ACTION: Proposed rule.

SUMMARY: This proposed rule would implement a case-mix adjusted bundled prospective payment system (PPS) for Medicare outpatient end-stage renal disease (ESRD) dialysis facilities beginning January 1, 2011, in compliance with the statutory requirement of the Medicare Improvements for Patients and Providers Act (MIPPA), enacted July 15, 2008. The proposed ESRD PPS would replace the current basic case-mix adjusted composite payment system and the methodologies for the reimbursement of separately billable outpatient ESRD services.

Background
1. Origins of the Composite Payment System
  
  Section 299I of the Social Security Amendments of 1972, Public Law 92-603, established the end-stage renal disease (ESRD) program under
  
  Medicare. That law extended Medicare coverage to individuals regardless of age who have permanent kidney failure, requiring either dialysis or kidney transplantation to maintain life, and meet certain other eligibility criteria. On July 1, 1973, the Medicare program extended benefits to about 11,000 beneficiaries with ESRD. In calendar year 1974, the program paid benefits of about $229 million for dialysis, transplant, and other services. By 1979, the number of beneficiaries had grown to 42,500, with payments reaching $985 million.
  
  Because of concern over the rapid escalation in expenditures for the ESRD program, the Congress enacted legislation in 1978 (Pub. L. 95- 292, ``ESRD Program Amendments of 1978''), which amended title XVIII of the Social Security Act (the Act) to add new section 1881, which governs Medicare payment for ESRD benefits. In particular, section 1881(b)(2)(B) of the Act directed us to publish regulations establishing methods and procedures to determine the costs incurred by
  
  ESRD providers and renal dialysis facilities in
  
  Page 49924
  
  furnishing covered services to individuals with ESRD, and to determine, on a cost-related or other equitable and economically efficient basis, payment amounts for part B services furnished by such providers and facilities to individuals with ESRD. Section 1881(b)(2)(B) of the Act also provided that we establish a prospective reimbursement method for those services with incentives for encouraging facilities to be more efficient and provide cost-effective care.
  
  The enactment of the Omnibus Budget Reconciliation Act of 1981,
  
  Public Law 97-35, resulted in a further directive for implementing changes to the ESRD payment system. Section 2145 of Public Law 97-35 amended section 1881 of the Act by requiring the Secretary to provide by regulation a method for determining prospectively the amounts of payments for dialysis services furnished by providers of services and renal dialysis facilities to individuals in a facility, and to such individuals at home. In particular, the law required that such method be based on a single composite weighted formula (``composite rate'')
  
  (which takes into account the mix of patients who receive services at a facility or at home and the relative costs for furnishing such services) for hospital-based facilities and such a single composite rate for other renal dialysis facilities, or that payment be based on such other method or combination of methods which differentiate between hospital-based and other renal dialysis facilities, and which would more effectively encourage more efficient delivery of dialysis services and would provide greater incentives for increased use of home dialysis.
  
  As a result of these statutory requirements, on February 12, 1982, we published a proposed rule on reimbursement for outpatient dialysis services (47 FR 6556) to implement section 1881 of the Act, as amended by section 2145 of Public Law 97-35. The regulations provided that each facility would receive a payment rate per dialysis treatment
  
  (``composite rate''), that is adjusted for geographic differences in area wage levels for the treatment furnished in the facility or at home. We refer to the methodology for payment of outpatient maintenance dialysis services on a per-treatment basis as the ``composite payment system''.
  
  Final regulations implementing the composite payment system were published on May 11, 1983 (48 FR 21254). The initial payment rates, which were developed from Medicare cost reports for fiscal years ending in 1977, 1978, and 1979, were established at $127 per treatment for independent facilities and $131 for hospital-based facilities. The composite payment system was effective August 1, 1983. It was limited to payments for the costs incurred by dialysis facilities furnishing outpatient maintenance dialysis, including some routinely provided drugs, laboratory tests, and supplies, whether furnished by hospital- based and independent facilities in a facility or at home. We established separate rates for hospital-based and independent dialysis facilities, and provided a process under which facilities with costs in excess of their payment rates could seek exceptions to those rates under specified circumstances.
  
  With regard to home dialysis, this system was the basis for reimbursing home dialysis furnished by hospital-based and independent facilities (``Method I''). (The other is ``Method II,'' under which the beneficiary works directly with a durable medical equipment supplier to obtain the supplies and equipment needed.) For further information on the distinctions between Method I and Method II, see section III.E of this proposed rule.
  
  The composite payment system implemented in 1983 was relatively comprehensive with respect to the renal dialysis services included as part of the composite payment bundle. However, a substantial portion of expenditures for renal dialysis services are excluded from the composite payment system and reimbursed in accordance with the respective fee schedules or other payment methodologies. For example, payment for erythropoiesis stimulating agents (ESAs) such as epoetin alfa (EPO, for example, Epogen[supreg]) and darbepoetin alfa
  
  (ARANESP[supreg]) used to treat anemia, and vitamin D analogues
  
  (paracalcitol, doxercalciferol, calcitriol), is made outside of the composite payment system as separately billable services. These separately billable services currently comprise about 40 percent of total spending for outpatient maintenance dialysis. The present payment for outpatient maintenance dialysis under Medicare represents a mix of prospective payment, fee-for-service, and other payment rules.
  
  Subsequent inflation increases to the composite payment system applied only in response to specific statutory directives. For example, between 1983 and 2001, the payment rates were increased only three times. A $1.00 increase per treatment was effective January 1, 1991 as a result of the enactment of the Omnibus Budget Reconciliation Act of 1990, Public Law 101-508. The rates were not revised again until the enactment of the Medicare, Medicaid, and SCHIP Balanced Budget
  
  Refinement Act of 1999, Public Law 106-113, which increased the payments by 1.2 percent effective January 1, 2000 and January 1, 2001, respectively.
  
  During the last few years, policymakers and other interested parties, including the Medicare Payment Advisory Commission (MedPac) and the Government Accountability Office (GAO), have examined the
  
  Medicare outpatient maintenance dialysis payment system and suggested a bundled prospective payment approach. See Medicare Payment Advisory
  
  Commission (MedPAC): Report to the Congress: Medicare Payment Policy,
  
  March 2001, March 2005, and March 2007, and GAO Report GAO-07-77, End
  
  Stage Renal Disease: Bundling Medicare's Payment for Drugs with Payment for All ESRD Services Would Promote Efficiency and Clinical
  
  Flexibility, November 2006. We believe that a fully bundled PPS would combine composite rate dialysis services with separately billable services under a single payment, adjusted to reflect patient differences in resource needs or case-mix. As in any PPS, dialysis facilities would keep the difference if Medicare payments exceeded costs for the bundled services, and would be liable for the difference if costs exceeded Medicare payments.
  
  Aside from resulting in a single comprehensive payment for all services included in the bundle, we believe a bundled ESRD PPS would have several objectives. These include eliminating incentives to overuse profitable separately billable drugs, particularly EPO, the targeting of greater payments to ESRD facilities with more costly patients to promote both equitable payment and access to services, and the promotion of operational efficiency. Because of the increased flexibility a bundled PPS would provide in the delivery of outpatient maintenance dialysis services, we believe that it could also increase desirable clinical outcomes, resulting in an enhanced quality of care.
2. Statutory Authority for a Bundled ESRD PPS 1. BIPA
  
  The Congress has twice required studies on the bundling of additional services into the composite payment system. In section 422(c)(2) of the Medicare, Medicaid, and SCHIP Benefits Improvement and
  
  Protection Act of 2000 (BIPA), Public Law 106-554, the Congress required the Secretary
  
  Page 49925
  
  to issue a report on a bundled system that would include separately billable drugs and clinical laboratory services routinely used in furnishing dialysis. The Secretary submitted this report, Toward a
  
  Bundled Outpatient Medicare End Stage Renal Disease Prospective Payment
  
  System, to Congress in May 2003. That report contained three major findings that would form the basis for the subsequent development of a bundled ESRD PPS: 1. Currently available administrative data are adequate for proceeding with the development of an expanded outpatient ESRD PPS. 2. Case-mix adjustment is potentially feasible based on available clinical information for ESRD patients in order to pay facilities appropriately for treating more costly resource intensive patients. 3. Current quality review initiatives provide a basis for monitoring the impact of a bundled ESRD PPS after implementation, to ensure quality of care does not deteriorate in response to the system's efficiency incentives.
  
  The Secretary's May 2003 report contained recommendations and conclusions drawn from research, which CMS had initiated on its own prior to the enactment of the law. In September 2000, the Kidney
  
  Epidemiology and Cost Center of the University of Michigan (UM-KECC) was awarded a multi-phased research contract. That research led to UM-
  
  KECC's August 2002 report, An Expanded Medicare Outpatient End Stage
  
  Renal Disease Prospective Payment System, Phase I Report. This report provided useful information on many of the issues that would need to be addressed before a bundled ESRD PPS could be implemented, and formed the foundation for the Secretary's May 2003 report. 2. MMA
  
  The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA), Public Law 108-173, also required the Secretary to submit to the Congress a report detailing the elements and features for the design and implementation of a bundled ESRD PPS. Section 623(f)(1) of the MMA specified that such a system should include the bundling of separately billed drugs, clinical laboratory tests, and other items
  
  ``to the maximum extent feasible''. That section also required the report to include a description of the methodology to be used to establish payment rates and that the report, detailing the design of an appropriate bundled payment system, be submitted to the Congress by
  
  October 1, 2005. Section 623(e) of the MMA also required a demonstration project testing the feasibility of using a fully bundled case-mix adjusted ESRD PPS.
  
  In addition to requiring a report on a bundled ESRD PPS, section 623 of the MMA amended section 1881(b) of the Act, by requiring significant revisions to the composite payment system. Specifically, section 623 of the MMA required:
  
  An increase of 1.6 percent to the composite payment rates effective January 1, 2005.
  
  An add-on to composite rate payments to account for the difference in payments for separately billable drugs based on a revised drug pricing methodology compared to the previous method.
  
  A ``basic'' case-mix adjustment to an ESRD facility's composite payment rate reflecting a ``limited number of patient characteristics.''
  
  That total payments under the basic case-mix adjusted composite payment system be budget neutral.
  
  An annual increase to the basic case mix adjusted payment amounts based on projected growth in expenditures for separately billed drugs (the ``growth update'').
  
  That payment rates be adjusted by a geographic index, as determined appropriate by the Secretary (and phased-in to the extent such index differed from the previous payment system).
  
  Reinstatement of the composite rate exceptions process, eliminated for most dialysis facilities beginning December 31, 2000 under BIPA, for ESRD pediatric facilities, effective October 1, 2002.
  
  On August 5, 2004 and November 15, 2004, we published a proposed rule and final rule (69 FR 47487 through 47730 and 69 FR 66235 through 66915), respectively, implementing the provisions affecting the composite payment system effective January 1, 2005, as set forth in section 623 of the MMA. We refer to the modified composite payment system as the ``basic case-mix adjusted composite payment system''. The development and application of the basic case-mix adjustments, using regression based adjustment factors for the patient variables of age, body surface area, and low body mass index, are explained in each of those rules. (For more information, we refer readers to 69 FR 47529 and 69 FR 66323, respectively.) The product of the specific adjusters for each patient, multiplied by the otherwise applicable composite payment rate, yielded the basic case-mix adjustment required by the MMA. The basic case-mix adjusted composite payment system was effective April 1, 2005, and was derived from UM-KECC's research summarized in its report,
  
  Methodology for Developing a Basic Case-Mix Adjustment for the Medicare
  
  ESRD Prospective Payment System (May 19, 2004 report and April 1, 2005 addendum).
  
  Subsequent to our implementation of the MMA requirements discussed above, UM-KECC continued its research to develop a case-mix adjusted
  
  ESRD PPS that would combine composite rate and separately billable services. UM-KECC reported its findings and recommendations in a final report submitted to CMS in February 2008, End Stage Renal Disease
  
  Payment System: Results of Research on Case-Mix Adjustment for an
  
  Expanded Bundle. That report is available on the Internet at: http:// www.sph.umich.edu/kecc/assets/documents/UM-KECC_Expanded_ESRD_
  
  Bundle.pdf. Individuals requiring special assistive technology may contact CMS at 410-786-4533 between the hours of 8:30 a.m. and 5 p.m. e.d.t. for assistance. UM-KECC's final report formed the basis for the
  
  Secretary's February 2008 Report to Congress, A Design for a Bundled
  
  End Stage Renal Disease Prospective Payment System, mandated under section 623(f)(1) of the MMA.
  
  The aspects of the basic case-mix adjusted composite payment system implemented as a result of section 1881(b)(12) of the Act, as added by section 623(d)(1) of the MMA, are important because they provide a foundation for the development of the case-mix adjusted bundled ESRD
  
  PPS required under Public Law 110-275, the Medicare Improvements for
  
  Patients and Providers Act of 2008 (MIPPA). Accordingly, we briefly describe below the basic case-mix adjustment under the current composite payment system before turning to the relevant provisions of
  
  MIPPA and the development of the proposed ESRD PPS. 3. The Basic Case-Mix Adjustment
  
  Resources required to furnish routine dialysis such as staff and equipment time vary by patient. For example, all other things being equal, larger patients cost more to deliver the same dose of dialysis than do smaller patients. Also, severely debilitated or aged patients may require more staff time than do younger healthier patients. Because of the variation in resources required to furnish routine dialysis to individuals with varying patient characteristics, facilities that treat a greater than average proportion of resource-intensive patients could be economically disadvantaged if they are paid a rate
  
  Page 49926
  
  based on average resources. In addition, patients who are costlier than average to dialyze may face difficulties gaining access to care because a fixed composite payment rate could create a disincentive to treat such patients. The purpose of a case-mix adjustment based on patient characteristics is to make higher payments to ESRD facilities treating more resource-intensive patients, according to objective quantifiable criteria. Such an adjustment also would reduce the disincentives to treat or provide the optimal dose of dialysis to such patients.
  
  The costs of providing the routine maintenance dialysis services that are paid under the composite rate are reported on the Medicare cost reports for hospital-based and independent ESRD facilities (Forms
  
  CMS 2552-96 and CMS 265-94, respectively). Patient-specific data related to the costs of furnishing composite rate services are not collected because these costs are included as part of the composite rate and are not separately billed. However, earlier UM-KECC research revealed considerable variability in costs and patient characteristics among dialysis facilities, and that several patient characteristics predicted facility costs. See Wolfe, R. et al., An expanded Medicare outpatient end stage renal disease prospective payment system, Phase I report, University of Michigan, Kidney Epidemiology and Cost Center,
  
  August 2002; Hirth, R.A., et al., Is case-mix adjustment necessary for an expanded dialysis bundle? Health Care Financing Review, Summer 2003, 24, pp. 77-88; Kidney Epidemiology and Cost Center: Methodology for developing a basic case-mix adjustment for the Medicare ESRD prospective payment system, May 19, 2004 report and April 1, 2005 addendum, prepared under contract no. N-12004-11-504200 for the Centers for Medicare and Medicaid Services.
  
  In order to determine a basic case-mix adjustment that could be applied to each ESRD facility's composite rate, UM-KECC further examined the relationship between facility-level costs for composite rate services based on the Medicare cost reports for hospital-based and independent facilities, and the average characteristics of patients treated by the facility. The research used data from Medicare cost reports for 3,254 independent and hospital-based ESRD facilities for 2000 to 2002, patient characteristics/co-morbidity data from CMS's
  
  Medical Evidence Form 2728 for 1995 through 2002, and Medicare claims for approximately 360,000 ESRD patients. See Hirth, R.A., et al.,
  
  Economic impact of case-mix adjusting the dialysis composite rate,
  
  Journal of the American Society of Nephrology, 16, 2005, pp. 1172-1176, and Wheeler, John R. C., et al., Understanding the basic case-mix adjustment for the composite rate, American Journal of Kidney Diseases, 47, No. 4, April 2006, pp. 666-671. Based on standard techniques of multiple regression analysis, UM-KECC found that age and body size had significant relationships to composite rate costs. The body size variables were body surface area (BSA) and low body mass index (BMI), calculated based on a patient's height and weight.
  
  A BMI less than 18.5 kg/m\2\ is considered a clinical measure of underweight status and is an indicator of patients who are malnourished or suffering from co-morbidities such as wasting syndrome. BSA is closely associated with the duration and intensity of dialysis required to achieve targets for dialysis adequacy. Facilities with a larger proportion of patients with a greater than average BSA, or with a BMI lower than 18.5, were found to have greater composite rate costs. The research also revealed a U-shaped relationship between age and composite rate costs, with the youngest and oldest age groups incurring greater costs for composite rate services due to resource needs.
  
  Although several co-morbidities were found to have statistically significant relationships to composite rate costs, CMS did not adopt them to develop the basic case-mix system mandated by the MMA for a number of reasons. For instance, the relationship of some co- morbidities to the composite rate costs was not stable over time. In addition, establishment of the diagnostic criteria used in connection with specific co-morbidities required further study.
  
  A few findings were surprising. For example, several patient characteristics, notably type 1 or type 2 diabetes, which generally are important with regard to the etiology of ESRD, did not show statistically significant relationships to composite rate costs for renal dialysis services. While the result that facilities with the greatest number of oldest patients incurred greater composite rate costs was expected, the finding that facilities with a higher proportion of patients in the youngest age group (a group that excludes pediatric patients or those less than age 18) incurred greater composite rate costs as well, was unexpected.
  
  The outcome of UM-KECC's research was a set of basic case-mix adjusters or multipliers for ESRD patients based on three variables.
  
  These variables were: (1) The patient's age (five groups), (2) BSA (a patient-specific value based on incremental differences from the national patient average), and (3) BMI category (two groups, value either less than, or equal to/greater than 18.5 kg/m\2\). CMS also developed a special adjuster for pediatric patients outside of UM-
  
  KECC's research methodology based on analysis of a sample of Medicare cost reports. The adjuster for each of these three variables is multiplied by the facility's composite rate to yield the current
  
  ``basic'' case-mix adjustment for each ESRD patient according to the specified patient characteristics.
  
  These adjusters were as follows:
  
  Composite rate
  
  Age group
  
  multiplier
  
  2) and has a BSA of 2.0 m2would be calculated as follows:
  
  Age Adjuster.............................. 1.055
  
  BSA Adjuster.............................. 1.037 (2.0-1.84)/0.1 = 1.060
  
  Low BMI Adjuster.......................... 1.112
  
  Case-Mix Adjuster......................... 1.055 x 1.060 x 1.112 = 1.244
  
  The resulting case-mix adjustment factor of 1.244 for this patient would be multiplied by the facility's otherwise applicable wage adjusted composite payment rate.
  
  The basic case-mix adjustment mandated under the MMA only affects the composite rate. It does not reflect costs associated with separately billable services. Separately billable services, particularly injectable drugs, are a significant component of the total dialysis resources used for each patient. Prior to the enactment of
  
  MIPPA on July 15, 2008, however, CMS did not have authority to bundle those services into a case-mix adjusted PPS.
  
  Page 49927
  
  4. MIPPA
  
  The implementation of the basic case-mix adjustments to the composite payment system effective April 1, 2005, and the Secretary's
  
  February 2008 Report to Congress, suggested that an expanded or bundled
  
  ESRD PPS which combined composite rate and separately billable services to yield case-mix adjusted payments was technically feasible. The report defined a payment bundle of dialysis-related services, described the methodology used to develop the regression based case-mix adjusters and the base period payment rates to which the case-mix adjusters would be applied, and discussed numerous other issues relevant to the bundling of outpatient dialysis services under a system of prospective payments. As a result of the July 15, 2008 enactment of MIPPA, section 153(b) of MIPPA amended section 1881(b) of the Act to require the implementation of an ESRD bundled payment system effective January 1, 2011 (herein referred to as the ``ESRD PPS''). Consistent with the language under the statute, we will refer to hospital-based and independent renal dialysis facilities as ``providers'' and
  
  ``facilities'', respectively, and when addressing both types of facilities, we will collectively refer to such entities as ``ESRD facilities'', as set forth in proposed Sec. 413.171. Section 153(b) of
  
  MIPPA specifies the following:
  
  The Secretary must implement a payment system under which a single payment is made to a provider of services or a renal dialysis facility for ``renal dialysis services'' in lieu of any other payment, and for such services and items furnished for home dialysis and self- care home dialysis support services.
  
  A definition for the ``renal dialysis services'' that are included in the bundle.
  
  The estimated amount of total payments under the ESRD PPS for 2011 must be equal to 98 percent of the estimated total amount of payments for renal dialysis services paid under Medicare, including payments for drugs, that would have been made with regard to services in 2011 if the new system was not implemented. Such estimate must be made based on per patient utilization data from 2007, 2008, or 2009, whichever year has the lowest per patient utilization.
  
  The ESRD PPS must include adjustments for case-mix variables, high cost outlier payments, and low-volume facilities and provide for a four-year transition (phase-in) period, with all facilities transitioned into the bundled ESRD PPS on January 1, 2014.
  
  ESRD facilities may make a one-time election before January 1, 2011, to be paid under the ESRD PPS and not go through the transition period.
  
  The ESRD PPS may include other payment adjustments, as the
  
  Secretary determines appropriate, including the use of a geographic index, and potential adjustments for pediatric patients and rural dialysis centers, and may provide for a unit of payment as the
  
  Secretary specifies (for example, per treatment or per unit of time).
  
  The ESRD PPS payment amounts must be annually increased by an ESRD bundled market basket beginning in 2012, and during the transition.
  
  Section 623(e) of the MMA, which requires a demonstration project of the use of a case-mix adjusted bundled ESRD PPS, be repealed.
  
  Section 153(a)(1) of MIPPA also requires that the composite payment rates be increased by 1.0 percent effective for services furnished on or after January 1, 2009, and before January 1, 2010, and increased by 1.0 percent for services furnished on or after January 1, 2010. In addition, section 153(a)(2) of MIPPA requires that the payment rate for dialysis services furnished on or after January 1, 2009, by ESRD providers of services, be the same as the payment rate for such services furnished by renal dialysis facilities. On November 19, 2008, we published the CY 2009 Physician Fee Schedule final rule (73 FR 69754), implementing the site neutral composite rate for ESRD facilities, and the CY 2009 1.0 percent increase to the composite rate.
  
  We expect to publish the CY 2010 1.0 percent increase to the composite rate in the CY 2010 Physician Fee Schedule final rule.
  
  In the following sections of this notice of proposed rulemaking, we describe the ESRD PPS we are proposing to implement effective January 1, 2011, in compliance with the statutory requirements of MIPPA.
Overview of the Proposed ESRD PPS

This proposed rule would implement a case-mix adjusted bundled PPS for Medicare outpatient ESRD dialysis patients beginning January 1, 2011, in accordance with the statutory provisions set forth in section 153(b) of MIPPA. We propose to implement this new system as described in proposed Sec. 413.172 and Sec. 413.215. The proposed ESRD PPS would replace the current basic case-mix adjusted composite payment system and methodologies for the reimbursement of separately billable outpatient ESRD services. Specifically, we propose that the ESRD PPS would combine payments for composite rate and separately billable services into a single base rate of $198.64 developed from CY 2007 claims data. Under the proposed rule, the base rate would be subsequently adjusted using patient-specific case-mix adjustment factors developed from separate equations for composite rate and separately billable services. The case-mix adjusters would include variables for age, body surface area (BSA), low body mass index (BMI), gender, eleven co-morbidity categories, and the onset of renal dialysis. These proposed adjustment factors were developed using standard techniques of multiple regression to yield case-mix adjusted payments per treatment. The per treatment payment amounts would also be adjusted to reflect urban and rural differences in area wage levels using an area wage index developed from Core Based Statistical Areas

(CBSAs definitions). The proposed rule also provides that ESRD facilities treating patients with unusually high resource requirements as measured through their utilization of identified services beyond a specified threshold would be entitled to outlier payments, that is, additional payments beyond the otherwise applicable case-mix adjusted bundled prospective payment amount. The proposed ESRD PPS also provides for special adjustments for pediatric patients and for facilities treating a low volume of ESRD patients, as well as a 4-year transition

(phase-in) period under which facilities would receive a blend of payments under the prior case-mix adjusted composite payment system and the new ESRD PPS.
The Proposed ESRD PPS Bundle

Section 1881(b)(14)(A)(i) of the Act, as added by section 153(b) of

MIPPA, specifies that the ESRD PPS must represent a single payment to

ESRD facilities for ``renal dialysis services'' in lieu of any other payment, and home dialysis supplies, equipment, and support services furnished pursuant to section 1881(b)(4) of the Act. Section 1881(b)(14)(B) of the Act, which identifies the renal dialysis services that are to be included in the ESRD PPS payment bundle, provides the following:

* * * the term ``renal dialysis services'' includes--

(i) Items and services included in the composite rate for renal dialysis services as of December 31, 2010;

(ii) Erythropoiesis stimulating agents and any oral form of such agents that are furnished to individuals for the treatment of end stage renal disease;

(iii) Other drugs and biologicals that are furnished to individuals for the treatment of

Page 49928

end stage renal disease and for which payment was(before application of this [new ESRD PPS]) made separately under this title, and any oral equivalent form of such drug or biological; and

(iv) Diagnostic laboratory tests and other items and services not described in clause (i) that are furnished to individuals for the treatment of end stage renal disease.

The methodology, which we subsequently describe, for the development of the proposed ESRD PPS, generally identifies the renal dialysis services that we propose to include in the proposed payment bundle in accordance with our interpretation of the statute. We also discuss in more detail below the definition for renal dialysis services under section 1881(b)(14)(B) of the Act.
1. Composite Rate Services
  
  Section 1881(b)(14)(B)(i) of the Act requires that the ESRD PPS payment bundle include composite rate services. As we indicated previously, the current case-mix adjusted composite payment system represents a limited PPS for a bundle of outpatient renal dialysis services that includes maintenance dialysis treatments and all associated services including historically defined dialysis-related drugs, laboratory tests, equipment, supplies, and staff time. It applies to Medicare beneficiaries receiving dialysis in ESRD facilities and to patients who have elected Method I home dialysis. (Under Method
  
  I, the ESRD facility with which the home patient is associated assumes responsibility for furnishing all home dialysis equipment, supplies, and home support services included in the provision of composite rate services. (See section 2740 of CMS Pub. 15-1.)) The ESRD facility receives reimbursement under the current case-mix adjusted composite payment system. For all other ESRD outpatient services not included in the composite payment rate under the current system, such items and services are billed separately in accordance with Medicare fee schedules and other payment methodologies under Part B and Part D. We propose to include in the proposed ESRD PPS those items and services included in the composite rate for renal dialysis services as of
  
  December 31, 2010, including self-dialysis training services, such as labor, supplies, and equipment(for greater detail, see discussion on self-dialysis training sessions in section E.2). Therefore, these costs for such composite rate services would be included in our computation of the proposed ESRD PPS base rate as explained in section VII. of this proposed rule. This not only would include payments for the costs of services directly related to dialysis, including payments for the costs of self-dialysis training sessions, but also payments authorized in accordance with the composite payment rate exception provisions set forth in 42 CFR 413.180 through 413.186. The costs for composite rate services are also included in our development of the composite rate regression model used to create the two equation patient specific case- mix adjusters that would be applied to the base rate. Composite rate services are defined in proposed Sec. 413.171.
2. ESAs and Their Oral Forms
  
  Section 1881(b)(14)(B)(ii) of the Act requires that ESAs and any oral form of such agents that are furnished to individuals for the treatment of ESRD be included in the ESRD PPS payment bundle. Epoetin alfa (EPO, for example, Epogen[reg]) and darbepoetin (ARANESP[reg]) are injectable ESAs, which are currently separately billable outside of the case-mix adjusted composite payment system. Payments for EPO[reg] and
  
  ARANESP[reg] would be included in the calculation of the proposed ESRD
  
  PPS base rate. These agents would also be included in the separately billable regression model used to create the two equation patient specific case-mix adjusters for the proposed ESRD PPS. We are currently unaware of any other injectable ESAs or oral forms of such ESAs used for the treatment of ESRD. However, should such agents become available subsequent to the implementation of the ESRD PPS on January 1, 2011, these agents would be considered renal dialysis services and subject to payment under the ESRD PPS. That is, consistent with the statute, we propose that no additional payment would be provided for such agents outside of the bundle of renal dialysis services included in the ESRD
  
  PPS. The inclusion of ESA's and their oral forms as renal dialysis services in the ESRD PPS payment bundle is set forth in proposed
  
  Medicare regulation 413.171.
3. Other Drugs and Biologicals and Their Oral Equivalents
  
  Section 1881(b)(14)(B)(iii) of the Act specifies that other drugs and biologicals that were furnished to individuals for the treatment of
  
  ESRD and for which payment was made separately under this title, prior to the implementation of the ESRD PPS, and their oral equivalent forms, must be included in the ESRD PPS payment bundle. Given the reference to
  
  ``this title,'' we interpret clause (iii) as requiring the inclusion in the ESRD PPS payment bundle all drugs and biologicals that were separately billable prior to the implementation of MIPPA under title
  
  XVIII of the Act. Therefore, we believe the ESRD PPS payment bundle would include all drugs and biologicals formerly separately payable under Medicare Part B and Part D. We recognize that an alternative reading of the last part of clause (iii) with respect to the phrase
  
  ``and any oral equivalent form of such drug or biological'' could be interpreted to limit the scope of the drugs and biologicals included in the bundle to only oral versions of injectables (or other non-oral routes of administration). However, we believe that this reading of the statute is unduly constrained. Therefore, our view is that the intent of clause (iii) is to include all drugs and biologicals formerly payable under either Medicare Part B or Part D used to treat ESRD, regardless of the route of administration.
  
  We believe that the exclusion of oral drugs and biologicals for which there is no injectable equivalent (or other non-oral form of administration) from the ESRD PPS would defeat one of the very purposes of the new system--the inclusion of all renal dialysis services furnished to ESRD patients in a comprehensive payment bundle to which a reasonable payment amount can be attached empirically. In addition, the exclusion of oral drugs and biologicals for which there is no injectable (or other non-oral) version does not make sense from a payment policy perspective. Such a policy would result in the gradual growth of excluded services from the ESRD PPS payment bundle, and the progressive erosion of the payment system, as new oral-only drugs and biologicals for the treatment of ESRD emerge. Moreover, we believe the inclusion of such drugs and biologicals is supportable under clause
  
  (iv). That is, we believe the language under clause (iv) addressing
  
  ``other items and services not covered in clause (i),'' provides sufficient authority to include all drugs and biologicals, including oral-only drugs and biologicals, used to treat ESRD in the ESRD PPS payment bundle. Therefore, we are proposing that drugs and biologicals used to treat ESRD that were separately payable prior to January 1, 2011, be included as part of the proposed ESRD PPS payment bundle.
  
  Accordingly, we propose to include such drugs and biologicals in the development of the proposed patient-specific case-mix adjusters and in the calculation of the proposed ESRD base rate to which the adjusters would be
  
  Page 49929
  
  applied. We identified specific National Drug Codes (NDCs) for drugs and biologicals previously payable under part D that we propose to include in the payment bundle. However, we propose that the ESRD PPS will apply, regardless of the emergence of new drugs or biologicals, or different NDCs for the classes of drugs and biologicals included in the
  
  ESRD PPS bundle. Finally, section 1881(b)(14)(B) of the Act specifically excludes vaccines from the payment bundle and, therefore, vaccines will not be included in the proposed ESRD PPS. We are seeking comments on our proposals above.
  
  We have found that eleven drugs and biologicals accounted for 99.7 percent of the payments under Part B for all injectable drugs and biologicals that were furnished to outpatient ESRD patients in CY 2007.
  
  These drugs and biologicals are epoetin alfa (EPO[reg]), darbepoetin alfa (ARANESP[reg]), calcitriol, doxercalciferol, paracalcitol, iron sucrose, sodium ferric gluconate, levocarnitine, alteplase recombinant, vancomycin, and daptomycin. These drugs and biologicals, as well as the others comprising 0.3 percent of the total payments for drugs and biologicals under Part B in CY 2007, would be included in the proposed
  
  ESRD PPS payment bundle. Of the top eleven injectable drugs and biologicals, several have oral versions. For example, levocarnitine, and the vitamin D analogues calcitriol, doxercalciferol, and paricalcitol are also available in oral form. The oral versions of these drugs are currently covered under Medicare Part D. Other drugs used to treat ESRD are available only in oral form and are currently payable under Part D. These include cinacalcet hydrochloride, lanthanum carbonate, calcium acetate, sevelamer hydrochloride, and sevelamer carbonate. Consistent with our interpretation of section 1881(b)(14)(B)(iii) of the Act, we propose that payments for all drugs and biologicals furnished to ESRD patients and separately billable prior to January 1, 2011, would be included under the proposed ESRD PPS payment bundle as renal dialysis services. Under this proposal, separate billing for these services would be prohibited. The proposed
  
  ESRD PPS methodology, both with respect to the computation of the case- mix adjusters and the calculation of the proposed ESRD base rate to which the adjusters would be applied, includes payments for these services. The inclusion of other drugs and biologicals and their oral equivalents as renal dialysis services in the ESRD PPS payment bundle is set forth in proposed Sec. 413.171.
4. Diagnostic Laboratory Tests and Other Items and Services
  
  Section 1881(b)(14)(B)(iv) of the Act requires that diagnostic laboratory tests not included under the composite payment rate (that is, currently separately billable laboratory tests) must be included as part of the ESRD PPS payment bundle. We propose to define such laboratory tests as laboratory tests that are separately billed by ESRD facilities as of December 31, 2010, and laboratory tests ordered by a physician who receives monthly capitation payments (MCPs) for treating
  
  ESRD patients that are separately billed by independent laboratories.
  
  Because many of the same diagnostic laboratory tests can be performed for both ESRD and non-ESRD patients, we believe that this approach for including laboratory services appropriately captures tests for inclusion in the payment bundle. We propose that payments for these laboratory services would be included in the development of the proposed patient-specific case-mix adjusters and in the proposed ESRD base rate to which the adjusters would be applied.
  
  Section 1881(b)(14)(B)(iv) of the Act also requires that the ESRD
  
  PPS payment bundle include ``other items and services not described in clause (i)''. We believe that this language can be reasonably interpreted to include other separately billable items and services used in the treatment of ESRD, such as supplies. Examples of such items and services would include, but not be limited to, items such as syringes, specialized tubing, as well as blood and blood products, which facilities may furnish during the dialysis treatment. We also believe that the language also can be interpreted to include the cost of other self-dialysis training services in the ESRD PPS (for further detail on self-dialysis training, see section E.2. below). We propose that such items and services be included in the ESRD PPS bundle. The inclusion of diagnostic laboratory tests and other items and services as renal dialysis services in the ESRD PPS payment bundle is set forth in proposed Sec. 413.171.
5. Home Dialysis Patients (Method I and II) and Self-Dialysis Training
  
  Section 1881(b)(4) of the Act authorizes the Secretary to make payment to providers of services and renal dialysis facilities, and to suppliers of home dialysis supplies and equipment, for the cost of home dialysis supplies and equipment and self-care home dialysis support services furnished to patients for self-care home dialysis. As a result of section 153(b) of MIPPA, as explained above, section 1881(b)(14)(A)(i) of the Act requires the Secretary to implement a payment system under which a single payment is made under this title to an ESRD facility for renal dialysis services and for such services and items furnished pursuant to section 1881(b)(4) of the Act. As we explained above, we also believe that self-dialysis training services would be considered renal dialysis services as defined in section 1881(b)(14)(B) of the Act. As a result, we are proposing that the costs of home dialysis services furnished to both Method I and Method II home dialysis patients under the current basic case-mix adjusted payment system, as well as self-dialysis training services, must be combined into a single payment under the proposed ESRD PPS. 1. Payment for Home Dialysis
  
  Currently, Hemodialysis, Continuous Cycling Peritoneal Dialysis
  
  (CCPD), Intermittent Peritoneal Dialysis (IPD) and Continuous
  
  Ambulatory Peritoneal Dialysis (CAPD) treatment modalities may be performed at home by appropriately trained patients. Medicare beneficiaries dialyzing at home must complete a Medicare Beneficiary
  
  Form (CMS-382) selecting between two methods of payment (Method I or
  
  Method II) as described below. a. Method I--The Composite Rate
  
  If a Medicare home dialysis patient chooses Method I, the ESRD facility with which the patient is associated must assume responsibility for providing all home dialysis equipment and supplies as well as providing home support services and receives the composite payment rate for such services. Support services needed to furnish home dialysis services include, but are not limited to: (1) Periodic monitoring of a patient's adaptation to home dialysis and performance of dialysis; (2) visits by trained technical personnel made in accordance with a plan prepared by a professional team; (3) unscheduled visits on an as needed basis; and (4) providing, installing, repairing, testing, and maintaining home dialysis equipment including appropriate water testing and treatment. For these services, the ESRD facility receives, in accordance with Sec. 414.330(a), the same Medicare dialysis payment rate as it would receive for an in-facility patient under the basic case-mix adjusted composite payment system. Under
  
  Method I, the ESRD facility bills the Medicare Administrative
  
  Contractor/Fiscal
  
  Page 49930
  
  Intermediary (MAC/FI) and the beneficiary is responsible for paying the
  
  Medicare Part B deductible and the 20 percent coinsurance on the
  
  Medicare rate to the facility. b. Method II--Dealing Directly With Suppliers
  
  In accordance with regulations at Sec. 414.330(a)(2), a Medicare
  
  ESRD beneficiary can elect to obtain home dialysis equipment and supplies from a supplier, that is not a Medicare approved dialysis facility (Method II). If a beneficiary elects Method II, the beneficiary will deal directly with a single Medicare Durable Medical
  
  Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) supplier to secure the necessary supplies and equipment to dialyze at home. The selected DMEPOS supplier (not a dialysis facility) must accept assignment and bills the Durable Medical Equipment Medicare
  
  Administrative Contractor (DME MAC). The beneficiary is financially responsible to the supplier for any unmet Medicare Part B deductible and for the 20 percent Medicare Part B coinsurance requirement. The amount of Medicare payment under Method II for home dialysis equipment and supplies may not exceed $1,974.25 per month for CCPD and $1,490.85 per month (57 FR 54186, published November 17, 1992) for all other modalities of home dialysis.
  
  For each beneficiary it serves, the supplier is required to maintain a written agreement with an approved ESRD facility to provide backup and support services. An ESRD facility that has a written agreement to supply backup and support services bills the MAC/FI for services provided under the agreement. Under Method II, an ESRD facility may be paid up to $121.15 (57 FR 54186, published November 17, 1992) per month for home dialysis support services, such as arranging for the provision of all ESRD related laboratory tests and billing for the laboratory tests that are included in the composite payment rate.
  
  An ESRD facility may not be paid for home dialysis equipment or supplies under Method II.
  
  Based on 2004-2006 data, only 3.1 percent of renal facilities report support service costs furnished to Medicare Method II home dialysis patients. The data also show that the number of Method II patients is small and has significantly declined over the study period
  
  (that is, 2004-2006) as shown below.
  
  Patients

  2004 4465.........................................................

  2006
  
  We are proposing that payment for all home dialysis services excluding physicians' services (See section III.F. below regarding the exclusion of physicians' services) would be included in the bundled payment to the ESRD facility, under the proposed ESRD PPS.
  
  In addition, as we indicated, section 1881(b)(14)(A)(i) of the Act requires that a single payment for renal dialysis services and items and services under section 1881(b)(4) be made to an ESRD facility.
  
  Therefore, since we are proposing that the costs of home dialysis services furnished under Method I and Method II (see section V Data
  
  Sources), regardless of home treatment modality, would be included in the proposed ESRD PPS, we also are proposing that the Method II home dialysis approach in its present form would no longer exist under the proposed ESRD PPS. With regard to payment limits for home dialysis services, in accordance with 6203(b) of Public Law 101-239, we published a final rule on November 17, 1992 implementing (57 FR 54179),
  
  Medicare program payment changes for home dialysis. In section 413.330(c), we set payment limits on what Medicare would pay for home dialysis supplies, equipment, and home support services as explained above. Accordingly, effective January 1, 2011, we propose to revise
  
  Sec. 414.330 to reflect that payment as established in section 1881(b)(14) of the Act will be the basis for home dialysis supplies, equipment, and home support services and therefore, Medicare would pay for home dialysis equipment, supplies and support services only under the prospective payment rate established in proposed 413.210 and payment limits previously established for such would no longer apply.
  
  We also note, that this proposal would not eliminate Method I in its present form. Therefore, effective January 1, 2011, a supplier could only furnish, under an arrangement with the ESRD facility, home dialysis equipment and supplies to a Medicare home dialysis beneficiary, and then the supplier would need to look to the ESRD facility for payment. We believe that this would reduce the administrative burden of maintaining two payment methods for home dialysis patients, since we believe that section 1881(b)(14)(A)(i) requires that all Medicare home dialysis patients would be paid under the ESRD PPS. We invite public comments on this proposal. 2. Self-Dialysis Training
  
  Currently, Medicare covers home hemodialysis training and two forms of PD training programs. Home dialysis and self-dialysis can only be performed after an ESRD patient has completed an appropriate course of training. The scope of training services that a certified facility provides to ESRD patients is described in Sec. 494.100(a). Medicare pays the ESRD facility its case-mix adjusted composite rate plus $12 per training treatment for CAPD and $20 per training treatment for
  
  CCPD. For hemodialysis training, Medicare pays the ESRD facility its case-mix adjusted composite rate plus $20 per training treatment
  
  (Medicare Claims Processing Manual, Chapter 8, Outpatient ESRD
  
  Hospitals, Independent Facility, and Physician/Supplier Claims, Section 50.8, Training and Retraining). We point out that effective January 1, 2011, under the proposed ESRD PPS, ESRD facilities would no longer receive an add-on of $12 for CAPD and $20 for hemodialysis and CCPD to the otherwise applicable payment amount per treatment for the costs of training. In addition, ESRD facility training expenses are included in the base period payment rate to which the combined rate and payment multiplier in the proposed two-equation model is applied.
  
  As we indicated, section 1881(b)(14)(B) of the Act, as added by section 153(b) of MIPPA, specifies the renal dialysis services that must be included in the ESRD PPS. Since self-dialysis training is used to train patients for the treatment modality of home dialysis with little or no help, we believe that these services would be considered
  
  ``renal dialysis services.'' As we indicated above, services related to self-training would meet the definition under clauses (i) and (iv) of section 1881(b)(14)(B) of the Act. As such, we propose to include the cost of self-dialysis training in the proposed ESRD PPS. We evaluated the current training cost reported by ESRD facilities (see section V
  
  Data Sources) to train ESRD patients for home dialysis. Training costs have been included in the composite rate payment adjusters in the proposed ESRD PPS. In section VIII.A. of this proposed rule, we point out that total composite rate costs included in the per treatment calculation include costs incurred for training expenses, as well as all home dialysis costs. We used the ESRD facilities cost reports to identify provider costs for training rather than payments. Therefore, in this proposed rule we propose to include
  
  Page 49931
  
  these costs in the composite rate portion of the two-equation ESRD PPS model described in section VI of this proposed rule. We believe that including training and home dialysis costs in the ESRD PPS would provide increased flexibility to dialysis centers for greater use of less costly PD and alternative treatment regimens such as nocturnal dialysis, home hemodialysis using compact portable dialysis machines, and shorter but more frequent dialysis sessions. For these reasons, we are proposing to include training and home dialysis costs in the proposed ESRD PPS, as set forth in proposed Sec. 413.217. Training costs were included in the calculation of the composite rate costs used to develop the regression-based adjustment factors for the composite rate portion of the two-equation model described in section VIII. In addition, the base rate to which the patient-specific case-mix adjustment factors are applied includes payments to ESRD facilities for training expenses. Because we are proposing that training costs under the ESRD PPS would be treated no differently than any other overhead expense, an explicit adjustment to the bundled payment amount for HD and PD training expenditures would not be necessary. We are seeking comments on our proposal to include home dialysis training services in the proposed ESRD PPS.
6. Physicians' Services
  
  Section 1881(b)(14)(A)(i), as added by MIPPA, states as follows in pertinent part:
  
  ``* * * the Secretary shall implement a payment system under which a single payment is made under this title to a provider of services or a renal dialysis facility for renal dialysis services (as defined in subparagraph (B)) in lieu of any other payment * * * and for such services and items furnished pursuant to [section 1881(b)(4)].''
  
  We believe this provision generally governs payment to ESRD facilities. With regard to physicians' services related to renal dialysis, such services are addressed in section 1881(b)(3) of the Act.
  
  At this time, we do not intend to significantly modify payment for physicians' services. Any changes with regard to the payment for physicians' services related to renal dialysis would be addressed in future rulemaking. Therefore, the scope of this proposed rule generally will be limited to payment for home dialysis and renal dialysis services furnished by ESRD facilities.
Unit of Payment

Under section 1881(b)(14)(C) of the Act, as added by section 153(b) of MIPPA, the ESRD PPS may provide for payment on the basis of renal dialysis services furnished during a week, or month, or such other appropriate unit of payment as the Secretary specifies. Approximately 92 percent of ESRD beneficiaries requiring outpatient dialysis undergo hemodialysis (HD), usually furnished in a facility. A small but increasing number of patients perform HD at home. The most typical schedule is 3 treatments per week, with each treatment averaging 3 to 4 hours. The remaining 8 percent of patients use peritoneal dialysis

(PD). PD is usually done at home, with or without machine assistance.

Unlike HD, which involves the circulation of the patient's blood and filtration of toxins using an artificial kidney machine, PD removes blood toxins through the draining of the dialysate from the lining of the abdomen or peritoneum several times a day. A form of PD, sometimes referred to as continuous cycling PD, is done with machine assistance while the patient sleeps, either at home or in specially designated areas at the ESRD facility.

Since the inception of the composite payment system in 1983, ESRD facilities have been reimbursed the applicable payment per treatment, with a maximum of 3 treatments for each full week a patient undergoes outpatient dialysis, unless additional treatments are justified by medical necessity. The 3-times weekly payment approach has applied regardless of whether the mode of dialysis is HD or PD. For example, an

ESRD facility's payment for a Method I home patient on PD for 21 days would be equal to 21/7 x 3 or 9 times the composite rate per treatment.

Both the Secretary's May 2003 and February 2008 reports on the development of a bundled ESRD PPS discussed the limitations of the per treatment method of payment under the composite payment system. For example, some have charged that the composite payment system's 3 times weekly payment structure, regardless of dialysis modality, has discouraged innovative treatment approaches that could lead to better clinical outcomes and an enhanced quality of life for patients. We believe that the argument is two-fold. First, the reliance on separately billable services as a source of revenue growth for ESRD facilities has potentially impeded the greater use of less costly PD

(which typically uses fewer separately billable drugs and less provider and facility overhead expense). Second, others argue that constraining payment based on number of treatments may reduce the use of alternative treatment regimens such as increased frequency nocturnal dialysis, home

HD using compact portable dialysis machines, and shorter but more frequent dialysis sessions (for example, 1.5 to 2 hours, five or six days per week).

These critics have maintained that combining composite rate and separately billable services during a specified interval of time would provide ESRD facilities the financing flexibility to use whatever forms of dialysis were in the best interests of the patient. Because ESRD facilities generally submit to Medicare a bill for all outpatient dialysis services furnished to a patient during the month, an ESRD PPS based on monthly payments was suggested as an alternative in the

Secretary's February 2008 Report to Congress. As we indicated above, section 1881(b)(14)(C) of the Act, as added by section 153(b) of MIPPA, gives the Secretary the discretion to establish an ESRD PPS based on an interval of time, or other appropriate unit of payment. In this notice we are proposing to establish an ESRD PPS which relies on a per treatment unit of payment. We propose to continue the present per treatment basis of payment in which ESRD facilities would be paid for up to three treatments per week, unless medical necessity justified more than three weekly treatments. ESRD facilities treating patients on

PD or home HD would also receive payments for up to three treatments for each week of dialysis, unless medical necessity justified the furnishing of additional treatments. Our reasons for continuing the present per treatment method of payment under the proposed ESRD PPS are set forth below.
1. Administrative Complexity Due to Phase-In
  
  Section 1881(b)(14)(E)(i) of the Act provides for a 4-year phase-in
  
  (transition), in equal increments for the implementation of the ESRD
  
  PPS. That is, the payments beginning January 1, 2011, must consist of a blend of the payment amounts under the new system and the prior payment rates in the following proportions:
  
  Prior
  
  New PPS
  
  payment

  Although ESRD facilities could elect to be excluded from the phase- in, in accordance with section 1881(b)(14)(E)(ii) of the Act, application of the phase-in under a monthly ESRD PPS would mean that a portion of each ESRD facility's total payments, would be based on a monthly payment methodology, while a portion would be based on the current per treatment system. We believe that combining a monthly ESRD
  
  PPS with the current per treatment methodology during the transition period would unduly complicate billing and increase the likelihood of payment errors and processing delays.
2. Administrative Complexity Due to Interruptions in Service
  
  A monthly payment approach under the ESRD PPS likely would not pose a problem for patients who receive their dialysis treatments at a single ESRD facility throughout the month with no interruptions in service. However, we note that this situation applies to about 81 percent of patient months. Approximately 19 percent of outpatient dialysis patients incur an interruption of service or receive their treatments at more than one facility during a month. The combination of intervening events in the available data for CYs 2004-2006 is shown in
  
  Table 1.
  
  BILLING CODE 4120-01-P
  
  Page 49933
  
  GRAPHIC
  
  TIFF OMITTED TP29SE09.000
  
  BILLING CODE 4120-01-C
  
  To properly account for events which interrupt a patient's outpatient dialysis, the days associated with these intervening events would have to be tracked and counted so that a pro rata reduction to the otherwise applicable monthly payment amount could be determined.
  
  This becomes especially cumbersome if a patient receives treatments at more than one facility and an interruption in service occurs (for example, due to hospitalization). Although Table 1 reveals that this circumstance occurs in less than 1 percent of patient months, the administrative complexity involved in monitoring events, which cause an interruption in the patient's normal schedule of receiving dialysis treatments, particularly where multiple
  
  Page 49934
  
  facilities are involved, would be considerable.
  
  Table 1 shows that for CY 2006, 79.05 percent of patient months did not involve an intervening event and did not include transfer to another facility. These patient months, when included with CY 2006 events that also account for an interruption of dialysis due to hospitalization, start of dialysis later in the month, or death/ withdrawal from dialysis, account for 94.09 percent of CY 2006 patient months. One option that we considered for the approximately 15 percent of patient months in which a patient did not undergo a full month of dialysis due to hospitalization, onset of dialysis later in the month, or death/withdrawal from dialysis, was applying a prorated monthly payment rate to cover these situations, and reverting to a per treatment payment methodology for all other situations. However, we believe that this approach would be too administratively complex. For example, under this approach a facility could find that some of its patients would be paid a full monthly ESRD PPS rate, those with an interruption in service would be paid a prorated monthly rate, and others would be paid based on a per treatment method.
3. No Incentive To Discourage Skipped Treatments
  
  A monthly ESRD PPS would afford facilities the maximum degree of clinical flexibility in treating patients. Facilities could provide whatever mode and frequency of dialysis, were in the best interests of the patient. However, under a monthly ESRD PPS, we believe that facilities may make less of an effort to discourage patients from skipping treatments. Because facilities do not receive reimbursement for skipped sessions under the current per treatment payment system, we are very concerned that a monthly ESRD PPS would provide no incentives for discouraging skipped treatments. Therefore, implementation of a monthly ESRD PPS would require either a stringent monitoring system to ensure the skipping of treatments does not become a byproduct of the new PPS's incentives, or require that a minimum number of treatments must be furnished to each patient in a month to ensure quality of care does not deteriorate. Both options would undercut two of the principles, which are part of the foundation of the new ESRD PPS, administrative simplicity and clinical flexibility.
  
  Given the difficulties of implementing a monthly ESRD PPS during a transition period in which a per treatment methodology applies, we are proposing to continue the present per treatment payment methodology in connection with the proposed ESRD PPS, as set forth in proposed Sec. 413.215. We may reconsider this decision after the transition period has ended. Some of the factors that we may evaluate at that time are whether the ESRD PPS has resulted in improved clinical outcomes, the degree to which facilities have increased the utilization of other modes of dialysis such as home PD, and whether interested stakeholders at that time would favor a monthly or other per unit of time payment methodology. We especially encourage comments from the industry and from organizations representing dialysis patients on our proposal to continue the per treatment methodology under the proposed ESRD PPS. In the following sections, we describe the data sources and analytical techniques used to develop the proposed per treatment ESRD PPS.
Data Sources

As discussed above, section 1881(b)(14)(B) of the Act, as added by section 153(b) of MIPPA, defines the renal dialysis services that must be included in the ESRD PPS. Based on our interpretation of the statute, we are proposing to construct the payment bundle using the following Medicare cost and payment information:

Composite rate services as measured using composite rate costs as calculated from the Medicare cost reports;

Drugs and biologicals (for example, injectables) that are separately billed by ESRD facilities on Medicare outpatient institutional claims;

Drugs and biologicals (for example, oral) used to treat

ESRD patients obtained from claims submitted by Part D stand-alone prescription drug plans;

Laboratory tests that are separately billed by ESRD facilities on Medicare outpatient institutional claims;

Laboratory tests ordered by a physician who receives MCPs for treating ESRD patients that are separately billed by independent laboratories;

Other items and services separately billed by ESRD facilities that are used in conjunction with injectable medications or laboratory tests, such as blood products, syringes, and other dialysis supplies that are billed on Medicare outpatient institutional claims.

While cost information for composite rate services is available from the Medicare cost reports, the cost report does not contain information on the costs of the separately billable categories of services noted above. Accordingly, the methodology described in this notice of proposed rulemaking applicable to separately billable services relies on separately billable payment information from

Medicare claims.

The descriptive statistics, case-mix model, and other analyses presented in this proposed rule are based primarily on CMS claims files for Medicare ESRD patients, and the Medicare cost reports for hospital- based ESRD outpatient dialysis providers and independent ESRD facilities. Resource utilization for separately billable services was based on patient-level Medicare outpatient claims for CYs 2004 through 2006. Since composite rate cost information is available only at the facility level, resource utilization for composite rate services was measured using the Medicare cost reports for each outpatient dialysis provider and facility (that is, hospital-based and independent facility). For the case-mix model for the proposed ESRD PPS, we relied on Medicare claims and cost reports for CY 2004 through CY 2006, because those years represented the latest most complete data available for the preparation of this proposed rule.

With regard to the budget neutrality requirement under section 1881(b)(14)(A)(ii) of the Act, which requires that the estimated total amount of payments for 2011 for renal dialysis services be equal to 98 percent of the estimated total amount of payments for renal dialysis services, that would have been made for services furnished in 2011 if the ESRD PPS had not been implemented, we are required to use per patient utilization data from 2007, 2008, or 2009, whichever has the lowest per patient utilization. To comply with this provision of the statute, we plan to evaluate available claims for Medicare ESRD beneficiaries for CYs 2007, 2008, and 2009 to determine which year resulted in the lowest average payment amount per treatment. Because the lowest payment amount per treatment would reflect the lowest utilization of outpatient ESRD services among patients absent evidence that per unit prices for those services declined, we believe that selection of the CY with the lowest payment per treatment for calculation of the ESRD base rate would comply with section 1881(b)(14)(A)(ii) of the Act.

Currently, the latest payment information from Medicare claims that is available in sufficient time for the preparation of this proposed rule is for CY 2007. Cost report information subsequent to CY 2006, and

Medicare claims data subsequent to CY 2007, could not be evaluated given the necessary lead time required to prepare this proposed rule.

We plan to examine

Page 49935

available Medicare cost report information for CYs subsequent to 2006 in developing the case-mix adjusters to ensure use of the latest available data, and available payment data from Medicare claims for CY 2008 and CY 2009 to comply with the lowest per patient utilization requirement of section 1881(b)(14)(a)(ii) of the Act, in preparing the final rule. Any later payment data used in developing the ESRD PPS published in the final rule, would be updated in accordance with the methodology explained elsewhere in this proposed rule. (See Section

VII., Development of Budget-Neutral ESRD Bundled Base Rate.)

We used several data sources for evaluating the patient and facility characteristics that were also used with the case-mix analyses. Patient demographic information was obtained from the Renal

Management Information System (REMIS)/Consolidated Renal Operations in a Web-Enabled Network (CROWN), and the ESRD Standard Information

Management System (SIMS). These data sources include the Medical

Evidence Report Form (Form 2728), which is completed at the onset of renal replacement therapy (RRT), which is either dialysis or transplantation to sustain life at the onset of kidney failure. Patient body size measures were developed from the height and weight values reported on the Form 2728. Beginning April 1, 2005, these values were obtained from the patient claims for outpatient dialysis. Patient co- morbidities were measured using the Form 2728, supplemented with diagnoses reported on Medicare hospital inpatient, skilled nursing facility, hospital outpatient, hospice, home health agency, and physician claims. The claims diagnoses were used to identify co- morbidities that were not abstracted using the Form 2728, and to capture changes in patient condition subsequent to the onset of kidney failure. Because diagnoses reported on laboratory claims may represent a suspected condition subject to testing rather than an established diagnosis, laboratory claims were not used to identify co-morbidities in the case-mix models.

We measured dialysis facility characteristics using a combination of SIMS (ownership type and geographic location), the Medicare cost reports (facility size), the Online State Certification and Reporting

System or OSCAR (hospital affiliation for satellite units), and other available information (for example, identifying facilities with composite payment rate exceptions).
1. Patient Claims Data
  
  The outpatient facility paid claims file is the primary source of information for payments ESRD facilities receive for the treatment of
  
  ESRD patients. The ``type 72X'' bills provided the detailed data for dialysis payments. The claims files used for the analyses in this proposed rule are based on patients with at least one claims record for dialysis. We used carrier claims and durable medical equipment claims to track dialysis-related payments to other providers such as independent laboratories.
  
  The case-mix models were based on claims from CYs 2004, 2005, and 2006. These were the most complete CY records available for use with the Medicare cost reports from the same periods to develop the payment methodology, given the lead time necessary for the preparation of this proposed rule. We plan to use available CY data subsequent to 2006 data in developing the payment methodology in connection with the final rule. The number of Medicare claims, patients, dialysis sessions, and
  
  ESRD facilities represented in the source claims data are shown in
  
  Table 2. We have also provided the same information for CY 2003 for comparison purposes.

  The primary case-mix analyses relied on pooled data from CY 2004 through CY 2006, which included a total of 8,041,181 Medicare ESRD patient months. The case-mix analyses included 95.4 percent of patients with Medicare outpatient dialysis claims during CYs 2004-2006. Over the 3-year period, the case-mix analyses included data for 453,789 Medicare
  
  ESRD patients treated in 4,250 ESRD facilities.
5. Prescription Drug Event Data, CY 2007
  
  We obtained the total CY 2007 payments for Medicare Part D drugs from Part D claims submitted by prescription drug plans (drugs formerly covered under Part D prior to the ESRD PPS). The claims were restricted to Part D claims submitted on behalf of Medicare ESRD beneficiaries with valid type 72X claims in CY 2007 and Part D coverage. We used claims for the following classes of drugs to calculate the estimated
  
  Part D payments for drugs used to treat ESRD (formerly covered under
  
  Part D) for inclusion in the ESRD PPS payment bundle:

Analytical Approach

In this proposed rule, we are presenting a case-mix model that UM-

KECC has developed using standard techniques of multivariate regression. In multivariate or multiple regression, a set of independent or predictor variables are tested to determine the extent they can predict or ``explain'' the variation in a related dependent or predicted variable. The unit of analysis in such models is important because the level at which resource use can be measured differs for composite rate and separately billable services. We can measure separately billable services for individual patients using the payment information obtained from Medicare claims. However, the available measure of resource use for composite rate services consists of costs from the Medicare cost reports. These costs do not distinguish patient- specific differences within ESRD facilities, because they combine treatment costs for all ESRD patients.

In the Secretary's February 2008 report to Congress, we described two approaches for developing the case-mix models using multivariate regression. Under the first approach, referred to as the one-equation model, composite rate costs and separately billable payments for all patients treated in each ESRD facility are added together. When the result is divided by the number of corresponding ESRD treatments, the predicted or dependent variable of bundled services reflects a facility-level model of combined composite rate and separately billable services. This approach has the relative simplicity of having the case- mix adjustments based on a single statistical model estimated at the facility level.

The other approach, which we refer to as the two-equation model, relies on two separate regression equations, one to predict variation in composite rate costs at the facility level, and the other to predict variation in separately billable payments at the patient level. This approach has the advantage of measuring patient-level variation in the utilization of separately billable services available from the Medicare claims. It also permits combining separate composite rate and separately billable regression equations into a single payment equation.

The case-mix model, which we have adopted in developing the proposed ESRD PPS, is based on the two-equation model. The basis for our selection of the two-equation model was set forth in the

Secretary's February 2008 report to Congress:

In an extensive series of analyses, UM-KECC determined that application of the one-equation bundled PPS model (that is, a facility-level model) yielded very different regression coefficients for a number of potential case-mix adjusters compared to the two- equation bundled PPS model. These differences were attributed to the correlation between the tested case-mix variables and unobserved facility characteristics. UM-KECC concluded that a patient-level model would have the advantage of reducing potential bias related to unobserved facility characteristics, would result in more precise coefficient estimates, and yield greater stability in these estimates over time. A patient-level model for the separately billable services can be combined with a facility-level model for composite rate services to yield a single payment equation.

This is the approach adopted to develop the case-mix adjusters for the ESRD PPS described in this proposed rule.

For those interested, a more extensive and detailed mathematical explanation of the two-equation model used to develop the case-mix adjusters is contained in UM-KECC's February 2008 report, End Stage

Renal Disease Payment System: Results of Research on

Case-Mix Adjustment for an Expanded Bundle (see pp. 38-44 and Technical

Appendix C).
Development of ESRD PPS Base Rate

The patient-specific case-mix adjustments developed from the two- equation regression model for composite rate and separately billable services, which we have described in section VIII. of this proposed rule, would be applied to a base payment rate per treatment (``base rate''). The base rate would also be adjusted to reflect ESRD facility differences in area wage levels using a proposed wage index as described in section VIII.C. In this section, we describe the calculation of the proposed ESRD base rate, as set forth in proposed

Sec. 413.220, and the computation of the reduction factors used to adjust the base rate for projected outlier payments and budget neutrality in accordance with sections 1881(b)(14)(D)(ii) and 1881(b)(14)(A)(ii) of the Act. The base rate presented in this proposed rule, and defined in proposed Sec. 413.171, was calculated entirely from CY 2007 Medicare claims data. The proposed base rate, which represents the average Medicare allowable payment (MAP) for composite rate and separately billable services, was developed from CY 2007 claims data. We used claims data for CY 2007 in connection with the preparation of this proposed rule because such data were the latest available. We expect to have claims data for CY 2008 and partial claims information for CY 2009 in connection with our preparation of the final rule. Comparing per treatment payment amounts developed from available claims data for CYs 2007, 2008, and 2009 would permit a determination as to which year resulted in the ``lowest per patient utilization'' of dialysis services as required in accordance with section 1881(b)(14)(A)(ii) of the Act. The components of the proposed base rate based on CY 2007 claims data and the methodology used to project the base rate to CY 2011 (the first year of the ESRD PPS), are described below.
1. Calculation of the CY 2007 Unadjusted Rate per Treatment
  
  Sections 1881(b)(14)(A)(i) and 1881(b)(14)(B) of the Act, as added by MIPPA, specify the renal dialysis services, and other items and services, which must be included in the payment bundle of the ESRD PPS.
  
  Table 8 shows the payments for the various components which comprise the renal dialysis services which we propose to include in our development of the base rate using available CY 2007 claims data, in accordance with our interpretation of the statute. We first describe each of the components of the ESRD PPS payment bundle included in the
  
  CY 2007 unadjusted rate per treatment. Thereafter, we describe the adjustments used to calculate the ESRD PPS base rate from the CY 2007 unadjusted rate per treatment.

  Page 49941
  
  BILLING CODE 4120-01-C 1. Composite Rate Services
  
  The first component of the ESRD PPS payment bundle shown in Table 8 is ``Outpatient dialysis and other composite rate services''. This line item refers to total CY 2007 payments for composite rate services as obtained from ESRD facility claims (bill type 72X claims). This total includes all composite rate payments to ESRD facilities, including exception payments made in accordance with Sec. 413.182 through Sec. 413.186. Claims from ESRD facilities that did not have a valid county code, such that the relevant CBSA-based wage index (see section
  
  VIII.C.) could not be determined, were excluded. In addition, claims for patients with a missing birth date, which is necessary in order to calculate the basic case-mix adjustment under the composite payment system, were also excluded. 2. Dialysis Support Services
  
  We computed a total amount for the next component of the ESRD PPS payment bundle shown in Table 8, ``Dialysis support services''. This total represents total payments for support services furnished to
  
  Method II home dialysis patients, and reported under subcategory 5 of revenue codes 082X through 085X on the type 72X claims. 3. Part B Drugs and Biologicals
  
  The next component of the ESRD PPS bundle shown in Table 8 is
  
  ``Part B drugs and biologicals''. We found that total payments for the top 11 Part B drugs and biologicals reported on the type 72X claims, accounted for 99.7 percent of total spending for Part B drugs. Monthly payments for Epogen were capped to reflect no more than 30,000 units per treatment, as amounts in excess of this value were considered clinically implausible. 4. Laboratory tests
  
  Another component of the ESRD PPS bundle shown in Table 8 is
  
  ``Laboratory tests billed by dialysis facilities or ordered by physicians receiving monthly capitation payments for treating ESRD patients''. Payments for laboratory tests represent the total amount paid to dialysis facilities for outpatient laboratory tests billed on the type 72X claims, as well as payments for laboratory tests ordered by physicians receiving MCP amounts and billed on carrier claims. We identified laboratory tests ordered by physicians receiving MCP using the list of physicians for CY 2006, which was the latest available list at the time of this proposed rule. The estimates for total laboratory payments will be updated using the list of CY 2007 MCP physicians in connection with the publication of the final rule. 5. DME Supplies and Equipment
  
  ``DME supplies and equipment'' is another component of the ESRD PPS payment bundle. Payments for these items and services were obtained from the CMS 1500 claims for Method II home patients. 6. Supplies and Other Services Billed by Dialysis Facilities
  
  This category of the ESRD PPS payment bundle primarily includes payments for syringes used in the administration of intravenous drugs during the provision of outpatient dialysis. These supplies and services were billed by the dialysis facilities on the type 72X claims. 7. Former Part D Drugs
  
  This amount represents total payments on behalf of the ESRD beneficiaries with Part D coverage in CY 2007 for Part D drugs and biologicals which we consider furnished for the treatment of ESRD.
  
  These drugs and biologicals, which are identified by class below, were obtained from CY 2007 Part D claims submitted on behalf of the Medicare
  
  ESRD beneficiaries with valid type 72X claims in CY 2007 with Part D coverage, using the NDC codes for the following drugs and biologicals:
  
  Vitamin D Analogues
  
  Calcitriol
  
  Paracalcitol
  
  Doxercalciferol
  
  Calcimimetic
  
  Cinacalcet hydrochloride
  
  Oral phosphate binder
  
  Lanthanum carbonate
  
  Calcium acetate
  
  Sevelamer hydrochloride
  
  Sevelamer carbonate
  
  The NDC codes used to identify the above drugs and biologicals are shown in the Appendix in Table C.
  
  The number of Medicare ESRD beneficiaries for which valid type 72X claims were filed in CY 2007, number of ESRD beneficiaries with Part D drug coverage, and number of beneficiaries with Part D claims for the specified drugs and biologicals noted above, are shown in Table 9. CY 2006 data are also shown in Table 9 for comparison purposes.

  Sevelamer Carbonate).
  
  The payment total for former Part D drugs includes payments by
  
  Medicare prescription drug plans, and all payments made by or on behalf of ESRD beneficiaries for the specified drugs. As noted in Table 9, the payment total for former Part D drugs only includes data for the 66.73 percent of ESRD beneficiaries who were enrolled in Part D. As a result, we do not have patient-specific information on the cost of drugs (part
  
  D equivalent drugs) for the remaining third of ESRD beneficiaries who do not have Part D coverage. To the extent these beneficiaries have drug coverage through their employer or other insurance, we do not have access to specific usage or payment information for these medications.
  
  Nonetheless, when the ESRD PPS is implemented January 1, 2011, former
  
  Page 49942
  
  Part D drugs would become renal dialysis services in accordance with section 1881(b)(14)(ii)(B) of the Act. As such, ESRD facilities would be responsible for providing ESRD-related oral drugs formerly covered under Part D to their patients.
  
  We are considering use of a proxy to capture the costs associated with ESRD-related drugs for those patients without Part D coverage. One possible approach would be for us to include payments under the Retiree
  
  Drug Subsidy (RDS) program which is described below. We believe that as the RDS payments could be made for ESRD-related drugs under title XVIII of the Act, use of RDS data would be consistent with section 1881(b)(14)(A)(ii) which requires that in implementing the ESRD PPS, the Secretary must ensure that the estimated total amount of payments under this title for 2011 for renal dialysis services equals 98 percent of the estimated total amount of payments that would have been made under this title if the ESRD PPS were not implemented.
  
  The RDS program was enacted in December 2003 by section 101 of the
  
  MMA. The program, which was effective January 1, 2006, was designed to support existing retiree benefit arrangements by providing subsidy payments to plan sponsors (that is, employers and unions). Subsidy payments to qualifying drug plan sponsors (for example, employers, unions) equal 28 percent of each qualifying retiree's allowable costs for prescription drugs otherwise covered by Medicare Part D, that are attributable to such drug costs between an applicable cost threshold and cost limit. For plan years ending in 2007, the applicable cost threshold is $265 and the cost limit is $5350.
  
  Based on CMS' Office of the Actuary's most recent CY 2007, we provided subsidy payments totaling $3.8 billion on behalf of 7.0 million beneficiaries. Plans submit aggregate qualifying cost data and a list of eligible beneficiaries. We could determine the number of ESRD qualifying covered retirees under the RDS as a percentage of all qualifying covered retirees under RDS. We could further estimate the
  
  ESRD-related percentage of the $3.8 billion in subsidy payments and add this amount to the estimated aggregate payments in 2007. We note that since we do not receive patient-specific information on drug usage under the RDS program, it would not be possible to capture the effect of these drugs on the patient and facility-level adjustment factors. We refer readers to 42 CFR Sec. 423.880 through Sec. 423.894 for more information on the RDS provisions. We invite public comment on this approach and other possible approaches to enable us to capture drug payment information for all Medicare ESRD patients. 8. Total MAP
  
  The total MAP amount represents the total payments made in CY 2007 for the composite rate and separately billable categories described above (that is, the sum of the payments for the items and services described in 1. through 7.) We propose to use the total MAP amount as the ESRD PPS base rate amount. 9. Total Medicare Hemodialysis-Equivalent Sessions
  
  In order to calculate the proposed ESRD PPS base rate per treatment, it was necessary to divide the total MAP amount described above by the number of Medicare HD-equivalent sessions. The number of
  
  Medicare HD-equivalent sessions represents the total Medicare treatments for outpatient dialysis as reported on the type 72X claims submitted by dialysis facilities. PD patient weeks were converted to
  
  HD-equivalent sessions. For this purpose one week of PD was considered equivalent to three HD treatments. Accordingly, a patient on PD for 21 days would have (21/7) x 3 or 9 HD-equivalent sessions. In determining the total number of Medicare treatments, the number of HD-equivalent sessions were capped at 20 per patient per month. We propose to use the total number of CY 2007 Medicare HD-equivalent dialysis sessions, 36,523,791, to calculate the ESRD PPS base rate. 10. Average MAP per Treatment
  
  We divided the total MAP in item 8, $9,239,987,362, by the total
  
  Medicare hemodialysis-equivalent sessions in item 9, 36,523,791, to yield an unadjusted rate per treatment for renal dialysis services in
  
  CY 2007. This unadjusted rate per treatment is $252.99. We propose to update this per treatment amount to reflect CY 2011 prices, and to standardize it to eliminate the effects of the case-mix and wage index adjustments in order to ensure duplicate payments do not occur under the ESRD PPS through the subsequent introduction of these variables in the payment formula. We also propose to further reduce the projected CY 2011 payment rate for estimated outlier payments, and the budget neutrality offset as set forth in sections 1881(b)(14)(D)(ii) and 1881(b)(14)(A)(ii) of the Act, respectively. This is the proposed amount per treatment that would be multiplied under the ESRD PPS to reflect patient-specific differences in case-mix, and other adjustments as set forth in section 1881(b)(14)(D) of the Act. We refer to this projected CY 2011 payment rate, after application of the standardization, outlier, and budget neutrality offsets, as the ESRD
  
  PPS base rate. The proposed definition of the base rate is set forth in proposed Sec. 413.171. Our proposed methodology for calculating the base rate to reflect the standardization, outlier, and budget neutrality reductions is explained in the sections that follow.
2. Determining the Update Factors for the Budget-Neutrality Calculation
  
  In order to estimate payments under the current payment system for each facility in CY 2011, the first year of the ESRD PPS, the components of the CY 2007 unadjusted per treatment rate were updated to reflect estimated 2011 prices, using the methodology as described in greater detail below. It is necessary to estimate 2011 payments under the current ESRD payment system (including all separately billable items) for each facility in order to meet the statutory budget- neutrality requirement for the ESRD PPS. Section 1881(b)(14)(A)(ii) of the Act requires that the ESRD PPS payment system be 98 percent budget neutral in 2011. In other words, the estimated total amount of payments under the ESRD PPS in 2011, including any payment adjustments, must equal 98 percent of the estimated total amount of payments for renal dialysis services that would have been made with respect to services in 2011 if the ESRD PPS system had not been implemented. Therefore, we must first estimate what ESRD facilities would have been paid under the current system in CY 2011, by updating the 2007 payments to reflect 2011 prices. We then divide the total estimated CY 2011 payments by the number of CY 2007 treatments to determine the CY 2011 average payment per treatment. We do not make adjustments for future changes in treatments as this would require us to make assumptions about patient specific characteristics. If we were to project CY 2011 treatments we would increase the current basic case-mix adjusted composite payments by the same amount. This would in effect have no impact on the calculation of the per treatment amount. This CY 2011 unadjusted per treatment payment amount becomes the basis for meeting the budget neutrality requirement. Below we describe the update factors used to estimate CY 2011 payments for each component. 1. Composite Rate Services
  
  In order to update the basic case-mix adjusted composite payments to 2011,
  
  Page 49943
  
  we began with the CY 2009 base composite rate ($133.81) and the CY 2009 drug add-on percentage of 15.2 percent. In accordance with section 153(a) of MIPPA and 1881(b)(14) of the Act, we updated the composite rate by 1.0 percent for CY 2010 and by the estimated ESRD bundled market basket percentage increase minus 1 percentage point (1.5 percent) for CY 2011 resulting in a 2011 composite rate of $137.18. A full description of the ESRD bundled (ESRDB) market basket is presented in section XII. of this proposed rule. We are proposing to use this base composite rate for CY 2011, which includes ESRD bundled market basket minus 1 percentage point, to update the CY 2010 composite rate for purposes of establishing the ESRD PPS base rate, given that we interpret section 1881(b)(14)(F)(ii) to require us to update the composite rate portion of the blend by the market basket percentage minus 1.0 percentage point in all years of the transition (which includes CY 2011). Therefore, using the market basket in this way would be a consistent approach. As described in section XII. of this preamble, we are proposing a market basket increase of 2.5 percent for
  
  CY 2011. Therefore, we are proposing a 1.5 percent update to the composite rate for CY 2011, resulting in a CY 2011 composite rate of
  
  $137.18 ($135.15 * 1.015). We note that the drug add-on percentage is reduced from 15.2 to 14.8 as a result of the increases to the composite rate in CYs 2010 and 2011. Since the drug add-on is calculated as percentage of the base composite rate, the drug add-on percentage decreases with increases in the composite rate. The CY 2009 Physician
  
  Fee Schedule final rule provides details on why increases to the base composite rate require decreases to the drug add-on percentage to ensure that the total drug add-on dollar amount remains the same (73 FR 69755). We intend to update the drug add-on, if necessary, for the ESRD
  
  PPS final rule.
  
  We used the applicable facility-level and patient-level basic case- mix adjustments from the CY 2007 claims to re-compute payment using the applicable basic case-mix adjustments applied to a 100 percent CBSA wage-adjusted composite rate using the most recently available ESRD wage index, which is the CY 2009 final rule ESRD wage index with a 0.60 floor. We did this to use the most recent wage indexes available in estimating 2011 payments. The other components of the bundle, which are discussed below do not have payments which are computed with wage indexes. We used a 0.60 floor because we anticipate that floor will be in effect in CY 2011. We have been reducing the wage index floor by .05 every year and we expect to continue this policy. (More information on
  
  CBSAs and the wage index floor is presented in section VIII.C.1 of this proposed rule).
  
  In addition, payment rates to facilities that have chosen to retain their exceptions under the basic case-mix composite payment system are not updated because, once approved, the exception amounts were fixed payment amounts, and hence the 2007 amounts represent the 2011 amounts.
  
  See the CY 2005 PFS final rule for a discussion regarding the application of statutory increases to exception amounts (69 FR 66332). 2. Self-Dialysis Support Services for Method II Patients
  
  The allowance per month under Method II for home dialysis support services may not exceed $121.15 per month for all forms of dialysis.
  
  Since home dialysis support services for Method II patients are subject to a monthly capitation payment that is not increased, the CY 2007 amounts represent the CY 2011 amounts. 3. Part B Drugs and Biologicals
  
  Under the current system, payments for ESRD drugs and biologicals under Part B are paid on average sales price plus 6 percent (ASP+6 percent) methodology. We reviewed ASP prices for four quarters of 2006, 2007, 2008 and two quarters of 2009 for the top eleven separately billable drugs. Given the variability shown in the prices over the last several years and the lack of a clear pattern, we propose to use the 2009 prices as proxy for 2011 values. At the time of the final rule, we will reevaluate this decision based on additional quarters of ASP drug pricing data. Thus, we used the growth from the average of the quarters for 2007 to the average of the two available quarters of 2009. For other ESRD-related Part B drugs, we used a weighted average of the top eleven Part B drugs to update those drug prices to 2011. Since the top eleven drugs represent 99.7 percent of total separately billable Part B drug payments, we believe that the overall weighted average was representative for the remaining 0.3 percent. See Table 10 for the growth factor that was applied to the 2007 drug payment levels.

  4. Laboratory Tests
  
  We updated payments for laboratory tests paid through the laboratory fee schedule to 2011 using projected CPI-U increases and any legislative adjustments that would be applied to this fee schedule.
  
  This is the statutory update required for lab services. This amount totaled a growth of 5.1 percent from 2007 to 2011. 5. DME Supplies and Equipment
  
  Since payments for supplies and equipment for Method II patients are subject to a monthly capitation payment that has not increased, the
  
  CY 2007 amount represents the 2011 amounts. 6. Supplies and Other Services
  
  This category primarily includes the $0.50 administration fee for separately billable Part B drugs. Since this fee has not increased, there was no price update. 7. Former Part D Drugs
  
  Former Part D drugs were updated by the growth rates for overall prescription drug prices that were used in the National Health
  
  Expenditure Projections. See http://www.cms.hhs.gov/
  
  NationalHealthExpendData/03_
  
  NationalHealthAccountsProjected.asp#TopOfPage for further reference on the National Health Expenditure Projections. Since we do not currently have enough data to establish a trend for Part D prices and since we use this price growth in the overall Part D projections, we believe it is an adequate proxy. This amount totaled a growth of 12.2 percent from 2007 to 2011.
  
  Once we determined updated CY 2011 payments for each component of the items and services discussed above, we added the components together to determine each ESRD facility's total payments under the current payment system in CY 2011. These estimated total 2011 MAPs divided by the total 2007 Medicare HD-equivalent sessions

  yield the unadjusted per treatment base rate for renal dialysis services in CY 2011 of $261.58.
  
  We used $261.58 as the starting point for further adjustments in determining the proposed ESRD PPS per treatment base rate. The 2011 unadjusted average payment per treatment of $261.58 was then used in the payment model to estimate total payments under the proposed ESRD
  
  PPS in CY 2011. These CY 2011 ESRD PPS estimated payments were based on treatment data from the CY 2007 claims file.
3. Standardization Adjustment
  
  CY 2011 payments under the proposed ESRD PPS were initially estimated without a budget-neutrality adjustment, using the unadjusted
  
  CY 2011 average payment per treatment amount of $261.58. We calculated the PPS payments using treatment counts from the 2007 claims file. The wage index and all applicable proposed patient-level and facility-level adjustments were applied to the unadjusted CY 2011 average payment per treatment to determine the estimated payment amount under the proposed
  
  ESRD PPS for each treatment and ESRD facility. We note that to simulate payments, we used the latest available final CY 2009 ESRD wage indexes, with no floor. While we anticipate a 0.60 floor for the ESRD wage index for the current basic case-mix composite payment system, we are proposing to eliminate the wage index floor for the ESRD wage index to be used for the proposed ESRD PPS in CY 2011 (see section VIII.C.1 for a detailed discussion of the ESRD wage index).
  
  Next, we standardized the ESRD PPS payments in order to account for the overall positive effects of the proposed ESRD PPS case-mix patient and facility adjustment factors and wage indexes. We must standardize payments in order to ensure that total projected PPS payments are equal to the payments under the current basic case-mix adjusted composite payment system. In order to standardize the ESRD PPS payments, we compared the proposed ESRD PPS amounts calculated from the treatment counts in the 2007 claims file to the current system payments from the 2007 Medicare claims file updated to 2011 (as explained in greater detail in section VII.B. above). A standardization factor was calculated by dividing total estimated payments in 2011 under the current payment system by estimated payments under the proposed ESRD
  
  PPS in 2011. The standardization factor was calculated to be 0.7827, or a reduction of 21.73 percent. As a result, the CY 2011 unadjusted per treatment base rate of $261.58 was reduced by 21.73 percent to $204.74.
  
  We are proposing that the base rate per treatment be further modified by the adjustments described below.
4. Calculation of the Budget-Neutrality Adjustments a. Outlier Adjustment
  
  Section 1881(b)(14)(D)(ii) of the Act provides that the ESRD PPS shall include a payment adjustment for high cost outliers due to unusual variations in the type or amount of medically necessary care, including variations in the amount of erythropoiesis-stimulating agents necessary for anemia management. We believe the payment adjustment under section 1881(b)(14)(D)(ii) of the Act for outlier cases should be applied in a budget neutral manner, as doing so will ensure that estimated total payments under the proposed ESRD PPS equals 98 percent of the estimated total amount of payments for renal dialysis services that would have been made with respect to services in 2011 if the ESRD
  
  PPS system had not been implemented.
  
  To ensure that the proposed outlier policy under the ESRD PPS is budget neutral, we propose to reduce the base rate by the proposed outlier percentage, or 1 percent. Specifically, we propose to reduce the base rate from $204.74 to $202.69. We did this to account for the 1 percent of aggregate ESRD PPS payments estimated to be made as outlier payments. We then re-estimated the prospective payment amounts with the new reduced base rate of $202.69, allowing 1 percent of payments to be outliers. The appropriate outlier payment amount for each treatment was determined as described in greater detail in section X.A.2 of this proposed rule. The outlier amount was computed for all treatments, and the total outlier payment, across all treatment amounts was added to the prospective payment amount for all treatments.
  
  In summary, we are proposing an outlier percentage of 1 percent; therefore, the proposed base rate per treatment must include a reduction of 1 percent. Thus the proposed standardized base rate of
  
  $204.74 was reduced by 1 percent to yield a proposed base rate of
  
  $202.69. b. 98 Percent Budget Neutrality Adjustment
  
  Section 1881(b)(14)(A)(ii) of the Act requires that the proposed
  
  ESRD PPS payment system be 98 percent budget neutral. In other words, the estimated total amount of payments under the ESRD PPS in 2011, including any payment adjustments, must equal 98 percent of the estimated total amount of payments for renal dialysis services that would have been made with respect to services in 2011 if the ESRD PPS had not been implemented. Therefore, we reduced the 2011 standardized base rate per treatment, which was already adjusted for 1 percent outlier payments, by an additional two percent, from $202.69, to yield a proposed base rate of $198.64.
  
  To summarize, the proposed base rate per treatment with an outlier adjustment and budget neutrality was calculated to be $198.64. This amount includes a 21.73-percent reduction from $261.58 to account for standardization to the projected CY 2011 current system payment per treatment, a 1-percent reduction to account for proposed outlier payments, and a 2-percent reduction for the required 98-percent budget neutrality. The outlier policy we are proposing is set forth at proposed Sec. 413.237.
5. Calculation of Transition Budget-Neutrality Adjustment
  
  Section 1881(b)(14)(E)(i) of the Act requires the Secretary to provide ``a four-year phase-in'' of the payments under the ESRD PPS for renal dialysis services furnished on or after January 1, 2011, with payments under the ESRD PPS ``fully implemented for renal dialysis services furnished on or after January 1, 2014.'' Although the statute uses the term ``phase-in,'' for purposes of the proposed ESRD PPS, we will use the term ``transition'' to be consistent with other Medicare payment systems.
  
  Section 1881(b)(14)(E)(ii) of the Act permits ESRD facilities to make a one-time election to be excluded from the transition. An ESRD facility that elects to be excluded from the transition receives payments for renal dialysis services provided on or after January 1, 2011 based on 100 percent of the payment rate under the ESRD PPS, rather than a blended payment based in part on the payment rate with regard to the current basic case-mix adjusted composite payment system and in part on the payment rate under the ESRD PPS. The implementation of the transition is discussed in section XIII.A of this proposed rule.
  
  The transition period policy is set forth in proposed Sec. 413.239.
  
  Section 1881(b)(14)(E)(iii) of the Act also requires that we make an adjustment to payments for renal dialysis services provided by ESRD facilities during the transition so that the estimated total amount of payments under the ESRD PPS, including payments under the transition, equals
  
  Page 49945
  
  the estimated total amount of payments that would otherwise occur under the ESRD PPS without such a transition. The transition budget neutrality adjustment would be comprised of two parts. First, we would make a payment adjustment under the basic case-mix adjusted composite payment system portion of the blended rate during the transition, in addition to computing a factor that would make the estimated total amount of payments under the ESRD PPS including payments under the transition equal the estimated total amount of payments that would otherwise occur without such a transition. We describe each part in detail in the paragraphs that follow.
  
  First, to ensure that estimated total payments during the transition equal the estimated total amount of payments that would otherwise occur without such a transition, in addition to accounting for payments for composite rate services and items and services that are separately billable under Part B, it is necessary to reflect payments for ESRD-related Part D drugs that are currently separately payable under Title XVIII. Specifically, as we discussed in section
of this proposed rule, section 1881(b)(14)(B) of the Act defines renal dialysis services to include, among other things, certain drugs and biologicals, including drugs and biologicals that were separately payable under Parts B and D. Under the current ESRD basic case-mix adjusted composite payment system, ESRD facilities generally do not furnish oral drugs and biologicals to their ESRD patients. ESRD patients currently acquire these drugs and biologicals either through

Medicare Part D, private insurance, or independently.

As described in section III. of this proposed rule, we are proposing to include renal dialysis service drugs formerly covered under Part D under the proposed ESRD PPS. As a result, we are further proposing that ESRD facilities would be required to furnish these and any other self-administered ESRD-related drugs to beneficiaries either directly or under arrangement.

As further discussed in section VII. of this proposed rule, the cost of the drugs and biologicals currently separately payable under

Part D that we propose to be designated as Part B renal dialysis services for purposes of the proposed ESRD PPS, would be reflected in the ESRD PPS portion of the blended payment. That is, once the ESRD PPS is implemented on January 1, 2011, ESRD-related Part D drugs would become Part B renal dialysis service drugs and would no longer be separately covered under Part D. This is due to section 1881(b)(14)(A)(1) of the Act, which specifies that after January 1, 2011, a single payment is made under title XVIII for renal dialysis services furnished by ESRD facilities in lieu of any other payment for such services, as well as the new statutory definition under section 1881(b)(14)(B) of the Act. In addition, we note that ESRD-related Part

D drugs are not part of the basic case-mix adjusted composite payment system or otherwise covered under Part B (in contrast to other separately billable ESRD-related items and services). As a result, ESRD facilities that elect to go through the transition would have no mechanism by which to receive payment for former Part D drugs with regard to the basic case-mix adjusted composite payment system portion of the payment blend (though such services would be captured with regard to the portion of the blended payment for the ESRD PPS). Because

ESRD-related Part D drug payments would not be included in the portion of the blend based on the basic case-mix adjusted composite payment system, payments to ESRD facilities that elect to go through the transition may be understated during the transition.

Additionally, as required by section 1881(b)(14)(A)(ii) of the Act and described in section VII.D.b of this preamble, the estimated total amount of payments under the proposed ESRD PPS in 2011, including any payment adjustments, must equal 98 percent of the estimated total amount of payments for renal dialysis services under title XVIII that would have been made with respect to services in 2011 if the ESRD PPS system had not been implemented. As we noted, Part D drugs are not part of the basic case-mix adjusted composite payment system or otherwise covered under part B as separately billable ESRD-related items or services. However, because the payments for the ESRD-related Part D drugs proposed for inclusion in the ESRD PPS were made under title

XVIII, we are required to include such items in the 98 percent budget neutrality adjustment.

Thus, to be consistent with the 98 percent budget neutrality requirement and to make estimated payments during the transition equal payments without the transition, we propose to provide a $14.00 per treatment adjustment to the portion of the blend with regard to the basic case-mix adjusted composite payment system. This amount is based on the 2011 per treatment ESRD-related Part D drug payments included in the proposed ESRD PPS base rate. We first computed the 2007 per Part D payment per treatment described in section VII.A. We then updated this amount to 2011 by applying the 12.2 percent update factor described in section VII.B.

We further propose that the $14 per treatment adjustment that would be made to the portion of the blend with regard to the basic case-mix adjusted composite payment system would be made without regard to basic case-mix adjustments or wage index adjustments. This is because ESRD- related Part D drugs were not included in the development of the adjustments for the basic case-mix adjusted composite payment system.

We considered an alternative approach for meeting the statutory transition budget neutrality adjustment. Under this approach, we would exclude estimated payments for ESRD-related Part D drugs from the estimated 2011 payments related to the basic case-mix adjusted composite payment system. That is to say, we would not pay ESRD facilities for the ESRD-related Part D drug payment with regard to the basic case-mix adjusted composite payment system portion of the blended payment during the transition, and therefore, we estimate that ESRD facilities may receive smaller blended payment amounts during the transition. Excluding ESRD-related Part D drugs from the basic case-mix adjusted composite payment portion of the blended payment would likely lower blended payments under the transition and, as a result, we estimate that many more facilities would elect to be paid 100 percent of the ESRD PPS rather than electing to go through the transition.

These facilities would have to give up their option to go through the transition in order to receive 100 percent ESRD PPS payments for ESRD- related Part D drugs. The transition provides a more gradual change to

ESRD PPS for those facilities that would receive lower payments under the proposed ESRD PPS. We believe it is more equitable to provide a $14 per treatment adjustment the portion of the blend related to the basic case-mix adjusted composite payment system. In addition, we believe that the transition budget neutrality adjustment should not change facilities' incentives with respect to whether or not to opt out of the transition. This approach would change the incentives because excluding

ESRD-related Part D drugs from portion of the blended payment related to the basic case-mix adjusted composite payment system might lower blended payments under the transition, thereby increasing the incentive to elect to be paid under 100 percent ESRD PPS. This approach also would skew the impact analysis because it compares payment amount related to the basic case-mix adjusted composite

Page 49946

payment system without Part D payments, while payments under the proposed ESRD PPS include payments for Part D drugs. For the impact analysis to accurately represent payments that are included in the proposed ESRD PPS and be consistent with the 98 percent budget neutrality requirement, we believe we need to include payments for

ESRD-related Part D drugs in our estimate of what ESRD facilities would be paid in 2011 for both the basic case-mix adjusted composite payment system and the proposed ESRD PPS, had an ESRD PPS not been implemented.

For these reasons we rejected this alternative.

Accordingly, in order to make ESRD PPS budget neutral during the transition with respect to ESRD-related Part D drugs, we propose to make a $14 per treatment adjustment to the portion of the blend related to the basic case-mix adjusted composite rate payment system.

The second part of the transition budget neutrality adjustment addresses the overall effect of the ESRD facilities' decision whether to be paid under the transition versus being paid under the ESRD PPS.

In the absence of such an adjustment, total payments would be higher under the transition payment system (blended payment amount) than under a 100 percent fully implemented PPS payment system, as we presume that each provider would likely choose the option that is most beneficial to them. In other words, we believe ESRD facilities that estimate that their aggregate payments will be higher under the transition than under the ESRD PPS likely will elect to be paid under the transition. This in turn would increase the total payments paid by CMS, with total payments then likely to exceed the 98 percent budget neutrality target amount, as discussed in section VII.D.b of this proposed rule. We interpret this provision as requiring, during the first 3 years of the transition, a budget neutrality adjustment applied to all payments to

ESRD facilities (both those paid under the transition and those electing to be paid under the ESRD PPS) to offset the additional payments to those ESRD facilities that elect to be paid a blended payment under the transition rather than to be paid based on 100 percent of the payment amount under the proposed ESRD PPS. Thus, we are proposing to create a transition budget neutrality adjustment factor to be applied to all payments to ESRD facilities during the transition.

This transition budget neutrality adjustment factor is intended to make the estimated total payments under the transition equal our estimate of total payments under the ESRD PPS were there no transition.

One alternative we considered was applying the budget neutrality adjustment factor to the 2011 ESRD PPS base rate only. However, we believe this approach would unfairly penalize those facilities that opt to be paid based on 100 percent of the payment amount under the ESRD

PPS, as it would lower all of their payments. Those facilities that are paid on a blended payment methodology would only have 25 percent of their payment lowered in CY 2011, as only 25 percent of the blended payment is based on the payment amount under the proposed ESRD PPS.

Thus, in effect, this approach would result in those facilities electing to be paid based on 100 percent of the payment rate under the

ESRD PPS subsidizing those electing to be paid under the transition. In addition, we believe that the transition budget neutrality adjustment should not change facilities' incentives with respect to whether or not to opt out of the transition. This alternative would change the incentives by lowering payments under the ESRD PPS by a larger percentage than the blended payments under the transition, thereby increasing the incentive to elect to be paid under the transition. For these reasons we rejected this alternative.

Another alternative we considered was applying the adjustment only to the blended payments for facilities that elect to be paid under the transition. However, we believe that this approach would unfairly penalize those ESRD facilities that choose to be paid under the transition, as it would lower their payments but would not lower the payments to those facilities that elect to be paid based on 100 percent of the payment rate under the ESRD PPS. Similar to the alternative in the previous paragraph, this alternative would also affect ESRD facilities' incentives with respect to whether or not to opt out of the transition, and thus we also rejected this alternative.

We therefore propose to apply the transition budget neutrality adjustment factor to all ESRD payments, including the component of the blended rates based on the current basic case-mix adjusted composite payment system. We propose this approach, because we believe that it would not unfairly penalize one group, it would evenly distribute the effect of the transition budget neutrality adjustment, and it would not change ESRD facilities' incentives with respect to whether to opt out of the transition.

In calculating the transition budget neutrality adjustment factor, we propose to first determine the estimated increase in payments under the transition and then determine an offset factor. In order to do this, we must first make assumptions on which facilities would choose to opt out of the transition and be paid based on 100 percent of the payment rate under the ESRD PPS in 2011. In order to estimate which

ESRD facilities will and will not elect to opt out of the transition, we are proposing to estimate aggregate payments for each ESRD facility under both the current basic case-mix adjusted composite payment system, including payments for separately billable services, and the proposed ESRD PPS (based on 100 percent of the payment amount under the

ESRD PPS). We are assuming that facilities that would receive higher aggregate payments under the proposed ESRD PPS would elect to be paid based on 100 percent of the payment rates under the ESRD PPS.

Conversely, ESRD facilities that would receive higher aggregate payments under the current basic case-mix adjusted composite payment system would elect to be paid the blended rate under the transition.

Based on this approach, we estimate that 36 percent of ESRD facilities will choose to be excluded from the transition and that 64 percent of ESRD facilities will choose to be paid the blended rate under the transition. Consequently, we estimate that during the first year of the transition, total payments to all ESRD facilities would exceed the estimated payments under the ESRD PPS in the absence of the transition. Thus, in order to maintain the 98 percent budget neutrality required by section 1881(b)(14)(E)(iii) of the Act during the initial year of the transition period, we are proposing to reduce all payments to ESRD facilities in CY 2011 by a factor that is equal to 1 minus the ratio of the estimated payments under the ESRD PPS were there no transition (that is, 98 percent of total estimated payments that would have been made under the current basic case-mix adjusted payment system) to the total estimated payments under the transition, or 3.0 percent. For 2011, application of this factor would result in a 3.0 percent reduction in all payments to ESRD facilities. We propose to apply this adjustment to both the blended payments made under the transition and payments made under the 100 percent ESRD PPS. We propose to calculate similar factors for CYs 2012 and 2013 that would allow a blended payment system to be budget neutral to a fully implemented 100 percent ESRD PPS.

We invite comments on the calculation and application of the

Cost Regression Used To Develop Proposed Payment Adjustment

Factors
1. Proposed Regression Analysis 1. Dependent Variables
The proposed two-equation regression approach used to develop the proposed ESRD PPS includes a facility-based regression model for composite rate service, and a patient-level regression model for separately billable services. The measures of resource use that were specified as the dependent variables in each of the two equations are explained below. a. Average Cost per Treatment for Composite Rate Services

We measured resource use for the maintenance dialysis services included in the current bundle of composite rate services using ESRD facility data obtained from the Medicare cost reports for hospital- based ESRD providers and independent ESRD facilities. The average composite rate cost per treatment for each ESRD facility was calculated by dividing the total reported allowable costs for composite rate services for CYs 2004, 2005, and 2006 (Worksheet B, column 11, rows 7- 16 on CMS 265-94; Worksheet I-2, column 11, rows 2-11 on CMS 2552-96) by the total number of dialysis treatments and Worksheet C, column 1, rows 1-10 on CMS 265-94; Worksheet I-4, column 1, rows 1-10 on CMS 2552-96). Continuous ambulatory peritoneal dialysis (CAPD) and continuous cycling peritoneal dialysis (CCPD) patient weeks were multiplied by 3 to obtain the number of hemodialysis equivalent treatments. We point out that our computation of the total composite rate costs included in this per treatment calculation includes costs incurred for training expenses, as well as all costs incurred by ESRD facilities for home dialysis patients. The resulting composite rate cost per treatment was adjusted to eliminate the effects of varying wage levels among the areas in which ESRD facilities are located using the CY 2009 ESRD wage index and the estimated labor-related share of costs from the composite rate market basket. The description of that labor-related share was contained in the Secretary's 2008 Report to

Congress. That is, 53.711 percent of each ESRD facility's composite rate cost per treatment was divided by the ESRD wage index to control for area wage differences. No floor or ceiling was imposed on the wage index values used to deflate the composite rate costs per treatment. We applied a natural log transformation to the wage-deflated composite rate costs per treatment to better satisfy the statistical assumptions of the regression model, and to be consistent with existing methods of adjusting for case-mix, in which a multiplicative payment adjuster is applied for each case-mix variable. As with other health care cost data, there was skewness in the cost distribution for composite rate services in which a relatively small fraction of observations account for a disproportionate fraction of costs. Cost per treatment values which were determined to be unusually high or low in accordance with predetermined statistical criteria were excluded from further analysis.

(For an explanation of the statistical methodology used to identify outlier composite rate costs per treatment, see pp 45-48 of UM-KECC's

February 2008 report.) b. Average Medicare Allowable Payment (MAP) for Separately Billable

Services

Resource use for separately billable dialysis related services was measured at the patient level using the payment data on the Medicare claims for CYs 2004-2006. This time period corresponded to the most recent 3 years of Medicare cost report data that were available to measure resource use for composite rate services. Measures of resource use included the following separately billable services: injectable drugs billed by ESRD facilities, including ESAs; oral forms of ESAs and other oral drugs used to treat ESRD payable under Medicare part D; laboratory services provided to ESRD patients, billed by freestanding laboratory suppliers and ordered by physicians who receive monthly capitation payments for treating ESRD patients, or billed by ESRD facilities; other services billed by ESRD facilities, including support services for Method II home patients; medical equipment and supplies for Method II home patients billed by durable medical equipment suppliers.

We obtained Medicare claims data for separately billable services for CYs 2004-2006 for patient months in which outpatient dialysis was provided and Medicare was the primary payer. For oral drugs (formerly) covered under Medicare part D, we used CY 2007 claims data for ESRD beneficiaries with Medicare part D coverage. Measures of resource use were based on MAPs, which were calculated using the payment data on the claims. Currently, the only payment data available for Part D claims are for CYs 2006 and 2007. However, these data were not available in sufficient time to be included in the development of the proposed separately billable case-mix adjusters, given the lead time necessary for the preparation of the proposed rule. We expect that additional

Part D claims data will be available for the preparation of the final rule. Therefore, we intend to include appropriate available payment data from Part D claims for CYs 2006 through 2008 in our development of the regression based case-mix adjusters for the overall payment model, and will address their inclusion in the final rule. Payments for Part D drugs were included in the proposed ESRD base rate, which relied on claims for CY 2007. See section VII.A.7.

Medicare payments were inflated by a factor of 1.25 for services that have a 20 percent patient coinsurance (for example, most injectable drugs) to yield the MAP. For laboratory tests that have no patient coinsurance obligation, the Medicare payment is identical to the MAP. As required under section 1881(b)(14)(B) of the Act, as added by section 153(b)(1) of MIPPA, vaccines are excluded from the ESRD PPS and therefore, were excluded from the computation of separately billable drugs. The MAP amounts do not include the annual part B payment deductible, which may apply to separately billable services because we were unable to determine whether the deductible amount was incurred in connection with another part B service. We point out that the part B payment deductible can apply in connection with any part B service, not just outpatient dialysis related services.

For the case-mix analyses, MAP values based on CY 2004 through 2006 claims were adjusted to approximate drug payments for the current year.

In CY 2007 the top 11 separately billed Part B drugs accounted for approximately 99.8 percent of drug expenditures for Medicare ESRD beneficiaries. We repriced the MAPs for these drugs in 2004, 2005, and 2006 by using a ratio. That ratio was obtained by dividing the Medicare payment rate in the first quarter of 2008 by the Medicare payment rate in 2004, 2005, and 2006. This repricing was done for the following injectable drugs: epoetin alfa, darbepoetin alfa (ARANESP[supreg]), iron dextran, iron sucrose, sodium ferric gluconate, calcitriol, doxercalciferol, paracalcitol, levocarnitine, alteplase recombinant, and vancomycin. (Although iron dextran was among the top 11 drugs in

CYs 2004-2006, it was superseded by daptomycin in CY 2007.) The resulting MAP closely reflects the current prices based on Medicare reimbursement rates. The ratios used to

Page 49948

adjust the MAPs for the 11 specified injectable drugs are shown in

Table 11.

BILLING CODE 4120-01-C

The adjusted MAP values were standardized to reflect the number of

Medicare outpatient dialysis treatments reported on the claims. This approach is consistent with the unit of payment under the current composite payment system. For patients who received PD during the month, the number of PD days reported on the claims was multiplied by

\3/7\ to obtain the number of HD-equivalent treatments. For example, 7

PD days were converted to 3 treatments since hemodialysis is typically performed 3 times per week. Monthly treatments reported on the claims were capped at 20 treatments in excess of this number were considered implausible. The average MAP per treatment for EPO was limited to no more than 30,000 units, since higher doses were considered clinically suspect or inappropriate. The ratio of the adjusted MAP values for separately billable services divided by the total number of treatments was used to calculate the average adjusted MAP per treatment. As with the analysis of composite rate services, we applied a natural log transformation to the values of the separately billable MAPs per treatment, with statistical outlier values excluded from further analysis employing the same criteria used to identify aberrant composite rate costs. 2. Independent Variables

Two major types of independent or predictor variables were included in the composite rate and separately billable regression equations-- case-mix payment variables and control variables. Case-mix payment variables were included as factors that may be used to adjust payments in either the composite rate or the separately billable equation.

Control variables, which generally represent characteristics of ESRD facilities such as size, type of ownership, facility type (whether hospital-based or independent), etc., were specifically included to obtain more accurate estimates of the payment impact of the potential payment variables in each equation. Control variables were excluded from consideration as actual payment adjusters because they represent facility characteristics rather than patient characteristics. In the absence of using control variables in each regression equation, the relationship between the payment variables and measures of resource use may be biased. a. Control Variables

Seven control variables were included in the regression analysis.

They were: (1) Renal dialysis facility type (hospital-

Page 49949

based versus independent facility); (2) facility size (10,000 dialysis treatments); (3) type of ownership (independent, large dialysis organization, regional chain, unknown); (4) whether the ESRD facility received a composite rate payment exception between November 1993 and

July 2001; (5) adequacy of dialysis, based on the percentage of patients having a urea reduction ratio (URR) (BSA-1.84)/0.1

As we found when we developed the current basic case-mix adjusted composite payment system, the regression analysis conducted for this proposed rule indicates that MAPs rise as a patient's BSA increases.

However, we have found that the case-mix adjustment based on a patient's BSA under the proposed ESRD PPS reflects slightly different values from those used in connection with the current basic case-mix methodology under the composite payment system. The BSA case-mix adjustment factor in connection with the current basic case-mix adjustment was 3.7 percent for every 0.1 m\2\ change in BSA from the national average of 1.84. The BSA case-mix adjustment factor under the proposed ESRD PPS is 3.4 percent for every 0.1 m\2\ change in BSA from a national average of 1.87 based on updated and more complete data.

In the regression analysis we conducted for this proposed rule, we found that BSA continues to be a strong predictor of cost variation among ESRD patients. Accordingly, we are proposing 1.034 as a payment adjustment factor for BSA in the proposed ESRD PPS. b. BMI

As discussed previously in section I.B.3, the current basic case- mix adjusted composite payment system includes a payment adjustment for low BMI (2. The forward (step-up) method begins with no variables in the model with variables individually included if they are statistically significant (no additional variables have a p-value level 2. As a result of our analysis, four patient characteristic variables (sex, age, AIDS and peripheral vascular disease) were found to be modest predictors of cost variation among ESRD facilities.

In the CY 2005 PFS proposed rule, we explained that a number of co- morbidities were analyzed, including several that did not have statistically significant relationships to facility costs, as well as co-morbidity conditions that were excluded due to lack of data. For example, we explained that a patient's history of cancer was associated with higher costs; however, we found the measure too broad to be clinically meaningful. We indicated that we would continue to evaluate cancer as a potential variable for refinement purposes.

We also discussed in that proposed rule that we explored whether diabetes as a co-morbidity is predictive of high resource use and found that the predictive power of diabetes was dependent on whether peripheral vascular disease (PVD) was part of the model. We explained that PVD was always statistically significant, when accounted for, while most diabetic measures were not strongly associated with facility costs. Therefore, we

Page 49953

proposed a case-mix adjustment for PVD diagnoses. We note that 73 percent of patients with diabetes also included PVD. (For more information on this discussion, we refer readers to 69 FR 47531).

In the CY 2005 PFS final rule with comment period, which implemented the current basic case-mix adjusted composite payment system, we acknowledged that although the regression modeling suggested the inclusion of co-morbidities in the basic case-mix adjusted composite payment system, we were concerned that the available data to determine patient level co-morbidities might not accurately reflect relevant diagnoses. For example, we explained that AIDS would not likely be recorded on claims for outpatient dialysis patients and that requiring its inclusion could create powerful incentives for ESRD facilities to circumvent confidentiality requirements (69 FR 66326). We also explained that we found that the predictive power of diabetes was dependent on whether PVD, which was statistically significant, was part of the model (69 FR 47531). However, most measures of diabetes were not strongly associated with ESRD facility costs. While we proposed a case- mix adjustment for PVD in the CY 2005 PFS proposed rule (69 FR 47531), we received comments indicating that there was apparent disagreement among clinicians as to whether certain diagnoses are reflective of PVD in ESRD patients. Therefore, we eliminated the case-mix adjustment for

PVD in the CY 2005 PFS final rule with comment period.

There also were other factors that contributed to our decision not to include patient-level co-morbidities in the basic case-mix adjusted composite payment system. For example, with regard to substance abuse, we acknowledged in the CY 2005 PFS proposed rule, while the presence of alcohol and drug dependence was found to be predictive of higher facility level costs, we did not propose an adjustment as we believed substance abuse was underreported. Accordingly, we concluded that we would not include co-morbidities as a case-mix adjustment. However, we did establish the case-mix adjustments based on age, BMI, and BSA. Our analysis indicated that patients with extremely low or high BMI were costly to treat and included these as we believed this factor could be an important measure of resource consumption related to the composite rate services and could serve as a surrogate for the severity of co- morbidities. We also noted that the average patient BSA was found to be statistically significant and a consistent predictor of average treatment costs, indicating higher costs for larger adult patients. As discussed above, in the CY 2005 PFS final rule with comment period, we indicated that while co-morbidities were not part of the current basic case-mix adjusted composite payment system, we encouraged all facilities to report co-morbid conditions on the claims in order to enable future refinements to the basic case-mix adjustments that would reflect the type of co-morbidities that beneficiaries receiving ESRD services have which would provide a better database from which we can develop future case-mix measures for the ESRD PPS.

As discussed in section VIII.A, we retained UM-KECC to assist us in developing a case-mix adjustment for the proposed ESRD PPS. One of the tasks was the identification of specific diagnoses within co-morbidity categories. For this proposed rule, to capture changes in patient conditions, patient co-morbidities were measured using a combination of the co-morbidities reported on the Medical Evidence Form (CMS-2728) to obtain co-morbidities at the onset of dialysis adjustment, and diagnoses reported on the Medicare claims to identify co-morbidities not obtained from the Medical Evidence Form (CMS-2728).

We began with a long list of patient characteristics based on diagnostic categories developed for the Medicare Advantage Program and categories developed for the co-morbidities on the Medical Evidence

Form (CMS 2728). We also used co-diagnoses reported in multiple types of Medicare claims (inpatient dialysis and other outpatient, skilled nursing facility, physician/supplier, hospice, and home health). We are soliciting recommendations on the type of claims that reflect the co- morbidities for beneficiaries receiving renal dialysis services that could be used in future analyses.

We acknowledge the likelihood that some diagnoses reported on laboratory claims may represent a condition being excluded by the test, and therefore, diagnoses reported on laboratory claims were not used. A potential limitation of excluding laboratory claims from the identification process is that we may have underestimated the frequency of certain conditions. Patient characteristics considered for inclusion in the model are based on the magnitude and statistical significance of relationship to composite rate costs and separately billable payments.

To ensure that each potential case-mix adjuster has a relationship to cost which is statistically significant and to ensure that the magnitude of the relationship is economically meaningful, patient co- morbidities having statistically significant, low magnitude association with cost, as well as co-morbidities with ambiguous definitions were excluded. Several patient co-morbidities having statistically significant, low magnitude association with cost in the preliminary models and additional co-morbidities with ambiguous definitions, high prevalence, or both, were excluded.

A refined list of case-mix co-morbidities comprised of 1,022 ICD-9-

CM diagnoses codes were evaluated for persistence of effect and cost.

The resulting co-morbidity categories were cardiac arrest; pericarditis; substance abuse; positive HIV status and AIDS; gastrointestinal tract bleeding; cancer since 1999 (excludes non- melanoma skin cancer); septicemia/shock; opportunistic infections

(pneumonias); aspiration and specified bacterial pneumonias; pneumococcal pneumonia, empyema, lung abscess; monoclonial gammopathy; myelodysplastic syndrome; leukemia; hereditary hemolytic anemias and sickle cell anemia; lymphoma; hepatitis B; and multiple myeloma.

We used the stepwise regression model in analyzing co-morbidity data for case-mix adjustments in the proposed ESRD PPS. The relationship between patient characteristics and cost for composite rate services was estimated using a facility level regression model, as patient level data are not available. In other words, the average patient characteristics are related to the reported facility costs.

A patient level model was used to identify potential payment adjusters for separately billable services. The regression model, weighted by the number of dialysis sessions examined the same refined list of patient characteristics used in the model of composite rate costs. Eleven co-morbidity variables had statistically significant relationships to cost. However, the magnitude of the co-morbidity effects varied substantially. The largest payment multipliers were associated with gastrointestinal (GI) bleeding (31.6 percent), HIV/AIDS

(31.6 percent), bacterial and other pneumonias/opportunistic infections

(30.7 percent), hereditary hemolytic/sickle cell anemias (22.6 percent) and pericarditis (19.5 percent). As infections, GI bleeding and pericarditis are acute conditions with a diagnosis not exceeding 3 months, these diagnoses would result in a temporary payment adjustment.

The chronic conditions

Page 49954

result in a permanent increase on payment which we believe may tend to have a more persistent effect on cost. For example, cancer diagnosis would be eligible for a payment adjustment if the cancer diagnosis has a direct effect on the cost of ESRD treatment. In other words, the fact that an individual has or had cancer would not in itself imply that a co-morbidity payment adjustment is warranted as the adjustment is intended to adjust for higher patient costs. The same applies for any diagnosis in any of the co-morbidity categories.

While the modeling approach used separate equations for the composite rate and separately billable services to select patient characteristics as payment variables, we combined the estimated payment multipliers for composite rate and separately billable services. The payment multipliers were calculated as the weighted average of the composite rate and separately billable multipliers. The weights reflect each component's proportion of the total estimated costs, so that the resulting case-mix adjustment reflects the overall relationship between patient characteristics and estimated costs for the proposed ESRD PPS.

We note that cancer is included in the proposed co-morbidity adjustment diagnoses. As discussed above, we indicated in the CY 2005

PFS proposed rule that although a history of cancer was associated with higher costs, it was found that the measure was too broad to be meaningful. Subsequent to the research we performed in support of the basic case-mix adjusted composite payment system, we investigated the relationship between specific categories of cancer and costs. In an effort to create more clinically homogenous groups, we began with clinical categories that were developed for risk adjustment under the

Medicare Advantage program. The source for these cancer diagnoses was the Medicare claims, based on any occurrence since 1999. Starting with all cancers except for non-melanoma skin cancers, we split them into groups of cancers that were used by the Medicare Advantage Program namely, lung; upper digestive tract and other severe cancers; lymphatic system, head, and other major cancers; metastatic cancers; breast, prostate, colorectal, and other cancers and tumors; lymphoma; multiple myeloma; and leukemia. We performed analyses to estimate the relationship between these diagnostic categories and separately billable MAPs. These analyses demonstrated statistically significant associations between each of the cancer categories and SB MAP. In fact, the coefficient estimates were similar across categories. To advance the goal of parsimony in the model, we recombined the categories.

We also note that AIDS is included as a co-morbidity case-mix adjustment although it had been eliminated as an adjustment from the current basic case-mix adjusted composite payment system as reporting of AIDS was limited due to confidentiality requirements (69 FR 66326.)

However, we found that inclusion of HIV/AIDS in the proposed ESRD PPS increases the explanatory power of the model and provides higher payments for patients who are substantially more costly to treat. We recognize that these benefits must be balanced against the goal to maintain patient confidentiality in this sensitive clinical area. The model that we are currently proposing is the result of applying a combination of empirical results and our policy decision regarding the appropriateness of adjusting for specific patient characteristics. We recognize that this may result in difficulties for ESRD facilities required by State law to maintain patient confidentiality and therefore are unable to comply with reporting HIV/AIDS diagnoses on claims. We also acknowledge facilities may not be aware of patients' HIV/AIDS status. We are specifically soliciting comments on our proposal to include HIV/AIDS diagnoses in the proposed model.

Based upon our analysis, we are proposing adjustments for the following eleven co-morbidity categories under the proposed ESRD PPS as indicated in table 14 below, and seek comment on each adjustment.

\1\ Payment multipliers were calculated as the weighted average of the composite rate and separately billable multipliers. The weights used reflect each component's proportion of the total estimated costs so that the resulting case-mix adjustment reflects the overall relationships between patient characteristics and estimated costs for an expanded bundle of services.

Diagnoses that relate to earlier periods of care and have no bearing on the current RRT are excluded from the proposed co-morbidity case-mix adjustment. Therefore, we are proposing that in order to be eligible for the proposed co-morbidity payment adjustment, the co- morbid condition must exist (or have existed within the past 3 months for the diagnoses, as noted above) and affect treatment. For each claim, we are proposing that an ESRD facility may receive only one co- morbidity case-mix adjustment per co-morbidity category, but it may receive an adjustment for more than one co-morbidity category.

We are proposing that in order to receive a co-morbidity payment adjustment, the appropriate ICD-9-CM code that corresponds to the specific condition/disease that results in increased costs to ESRD facilities is to be placed on the claims and that coding guidelines are to be used in determining the appropriate codes. This includes using V codes for those conditions that reflect that a patient had a disease/ condition in the past and that the disease/condition has no effect on the cost of providing RRT. That is to say, we propose that these V codes (that is, history of a disease) for past disease/condition are not subject to any co-morbidity payment adjustment. We note we will issue through sub-regulatory guidance, any changes in codes eligible for a co-morbidity payment adjustment in the event of any changes in coding (for example, ICD-10-CM) in the future.

We performed analyses on FY 2007 dialysis claims to determine the extent that specific diagnoses within the eleven co-morbidity categories are on ESRD claims. We found that less than 50,000 claims out of three million (representing 1.7 percent of 3 million claims) had a diagnostic code corresponding to the co-morbidity categories eligible for a co-morbidity payment adjustment. Of these, 40,609 diagnoses related to septicemia and shock; 2,853 related to cancer; 1,933

Page 49955

related to Hepatitis B, and 973 to HIV/AIDS.

We also analyzed the ICD-9-CM diagnostic codes as identified by UM-

KECC. A complete list of the codes identified by UM-KECC is found in

Table A of the Addenda.

Table B, which can be found in the Addenda represents the codes associated with diseases/conditions that would be recognized for the purposes of an ESRD co-morbidity payment adjustment.

Please note that we have eliminated specific ICD-9-CM codes associated with specific diseases/conditions that we propose would not be recognized for purposes of a co-morbidity payment adjustment. These ineligible codes are discussed further below.

ICD-9-CM Codes With Their Associated Conditions/Diseases Not Recognized for the Purposes of a Co-morbidity Payment Adjustment

Based on our analyses, we are proposing that conditions/diseases associated with the following ICD-9 codes will not be recognized for the purposes of a co-morbidity case-mix adjustment. We explain the reason for not recognizing these codes in the sections discussed below.

We are soliciting comments regarding the conditions/diseases associated with the excluded codes. We are also soliciting suggestions of ICD-9-CM codes for conditions/diseases associated with which we should consider for future refinements. 1. ICD-9-CM Co-morbidities Not Affecting Costs in Outpatient ESRD

Facility and Not Recognized for Co-morbidity Payment Adjustment(s)

We believe that patients with the following co-morbidity condition(s) in Table 15 below, would not result in higher costs in an

ESRD facility. We believe that patients with these acute conditions/ diseases, many which are highly communicable, would not receive dialysis in an outpatient setting and therefore, a history of these conditions/diseases would not have an impact on ESRD provider/facility costs. Therefore, we are proposing that these conditions would not be recognized for purposes of the proposed co-morbidity adjustment. We are soliciting comments on these ICD-9-CM codes and their associated diseases/conditions.

3. ICD-9-CM Benign Tumor Codes Not Recognized for Co-Morbidity Payment

Adjustment(s)

As noted previously, the intent of the case-mix adjustment is to provide additional payment for conditions which are predictors of variation of average costs. Although the regression analysis identified cancer as a co-morbidity category because it resulted in higher costs, we believe that this would exclude benign tumors. Therefore, we are proposing that the following benign tumor codes/diagnoses in Table 17 will not be recognized for the proposed cancer co-morbidity payment adjustment.

6. Race/Ethnicity

Section 1881(b)(14)(D)(i) of the Act requires that the ESRD PPS include a payment adjustment based on case-mix that may take into account a patient's race and ethnicity. Consequently, we analyzed race and ethnicity as part of the regression analysis for the proposed ESRD

PPS to inform our proposal for this rule.

Prior to the enactment of MIPPA, we considered race and ethnicity as potential patient level payment adjusters. First, race was one of the 35 patient characteristics that were examined in developing the basic case-mix adjustments to the ESRD composite rate required under section 1881(b)(12) of the Act. Ultimately, however, the final basic case-mix adjusted composite payment system published in the CY 2005 PFS final rule with comment period did not include adjustments for race and ethnicity. (For more information, we refer readers to 69 FR 66330.)

We again considered race and ethnicity as potential patient level payment adjusters as part of our research for the Secretary's 2008

Report to Congress. In the Report, we concluded that although race and ethnicity perhaps had a statistically significant relationship with costs and payments, such indicators were judged not to be suitable for making payment distinctions in a bundled ESRD PPS given that race/ ethnicity is not objectively measured.

Specifically, because there is no quantifiable mechanism by which to measure one's race or ethnicity, the classification is commonly based on self-reported information. We believed that more measurable indicators of cost and payment would be the patient's underlying clinical conditions. We further noted in the Report a demonstrated significance that race has on provider costs and drug utilization, indicating that this adjustment may warrant further consideration in the development and implementation of a new ESRD PPS. We note that any relationship between race/ethnicity and costs and payments revealed in the analyses conducted for purposes of this ESRD PPS proposed rule is discussed further in the sections that follow.

The regression analysis conducted for purposes of this proposed rule relied on two separate data sources for race and ethnicity status to assess the extent to which race and ethnicity would account for cost factors that are otherwise unexplained in the model. The first analysis was based on race and ethnicity data retrieved from the Renal

Management Information System (REMIS) and the second analysis was based on data retrieved from the Medicare Enrollment Database (EDB). In Table 19 below, the table captures the key differences in racial and ethnic categorizations between the REMIS and EDB databases.

For rural Massachusetts, we propose to adopt the methodology originally adopted for CY 2008 for establishing a wage index value for rural Massachusetts. Because we had used the same wage index value for 2 years with no update, we believed it was appropriate to establish a methodology which employed reasonable proxy data for rural areas (including rural Massachusetts) and also permitted annual updates to the wage index based on that proxy data. We used the average wage index values from all contiguous CBSAs as a reasonable proxy for rural Massachusetts. In determining an imputed rural wage index, we interpret the term ``contiguous'' to mean sharing a border. In the case of Massachusetts, the entire rural area consists of Dukes and Nantucket

Counties. We determined that the borders of Dukes and Nantucket counties are contiguous with CBSA 12700, Barnstable Town, MA and CBSA 39300, Providence-New Bedford-Fall River, RI-MA. We propose to continue to use this methodology that averages the wage index values for the contiguous CBSAs, Barnstable Town, MA (CBSA 12700) and Providence-New

Bedford-Fall River, RI-MA (CBSA 39300) for an imputed wage index value for rural Massachusetts for CY 2011.

For Hinesville, GA (CBSA 25980), which is an urban area without specific hospital wage data, we propose to continue to use the methodology that was adopted in the CY 2007 PFS final rule (71 FR 231), which was to impute a wage index value for Hinesville, GA, using the average proposed ESRD wage index value for all urban areas within the

State of Georgia.

With regard to rural Puerto Rico, we are proposing a different policy under the proposed ESRD PPS. In particular, we have previously applied the ESRD wage index floor for rural Puerto Rico because all areas in Puerto Rico that have a wage index were eligible for the ESRD wage index floor. However, as we stated earlier in this section, for the proposed ESRD PPS, we are proposing to eliminate the use of a wage index floor under the proposed ESRD PPS wage index. Therefore, for rural Puerto Rico, we propose to use the value for rural Puerto Rico

(0.4047) that has been used by other payment systems that do not use a wage index floor. This wage index value is the latest available wage index value for rural Puerto Rico and is currently used for rural

Puerto Rico by other payments systems that do not have a wage index floor. We note that there are currently no ESRD facilities located in rural Puerto Rico.

We are also proposing to use the labor share as measured by the proposed ESRD bundled market basket, which is 38.160 percent (as described in section XII. of this proposed rule). We note that the labor-related share from the proposed ESRD bundled market basket

(38.160 percent) is lower than the labor-related share from the existing ESRD composite rate index (53.711 percent) because there are no labor costs associated with the separately billable portion of the proposed ESRD bundled market basket. Our proposed adjustment for wages is set forth in proposed Sec. 413.231. For this proposed rule, we used the most current final wage index that was available at the time analysis was completed. This was the final CY 2009 wage index data. As stated earlier in this section, the ESRD wage index values used in the basic case-mix adjusted composite payment system are calculated without regard to geographic reclassifications authorized under section 1886(d)(8) and (d)(10) of the Act and utilize pre-floor hospital data that are unadjusted for occupational mix (71 FR 69685; 73 FR 69758). We are proposing to use the same wage index for the ESRD PPS.

As we previously noted, in our current basic case-mix adjusted composite payment system, we incorporate the wage index budget neutrality factor into the wage index values. Since the CY 2009 ESRD wage index has the same values as the FY 2009 SNF PPS wage index, we recommend that entities wishing to replicate our analysis refer to the

FY 2009 final rule where the FY 2009 Skilled Nursing Facility (SNF) PPS wage index was published. The FY 2009 SNF PPS final rule (73 FR 46415) includes tables with these wage index values. Table 8 shows the wage index values for urban areas (73 FR 46441 through 46462) and table 9 shows the wage index values for rural areas (73 FR 46462).

Since the ESRD PPS will be implemented in CY 2011, we believe it is appropriate to use CY 2011 wage index values. However, the wage data will not yet be available when the ESRD PPS final rule is published.

Therefore, we propose to include the proposed CY 2011 ESRD PPS wage index data for purposes of the ESRD PPS (that would not include any wage index budget neutrality adjustment) along with the CY 2011 proposed update to the existing basic case-mix adjusted composite payment system. We anticipate that this would be published in the CY 2011 Physician Fee Schedule proposed rule, which we expect to be published in the summer of 2010. We also propose to publish the final

CY 2011 ESRD PPS wage index along with the CY 2011 final rule update to the existing basic case-mix adjusted composite payment system. We anticipate that this would be published in the CY 2011 Physician Fee

Schedule final rule, which we expect to be published in November of 2010. 2. Low-Volume Adjustment a. Statutory Authority

Section 1881(b)(14)(D)(iii) of the Act requires a payment adjustment that ``reflects the extent to which costs incurred by low- volume facilities (as defined by the Secretary) in furnishing renal dialysis services exceed the costs incurred by other facilities in furnishing such services, and for payment for renal dialysis services furnished on or after January 1, 2011, and before January 1, 2014, such payment adjustment shall not be less than 10 percent.'' b. Defining a Low-Volume Facility

As indicated above, section 1881(b)(14)(D)(iii) of the Act authorizes the Secretary to define ``low-volume facilities'' for purposes of a payment adjustment in the proposed ESRD PPS. We believe the low-volume adjustment should encourage small ESRD facilities to continue to provide access to care to an ESRD patient population where providing that care would otherwise be problematic. UM-KECC has performed analyses using data from CMS Medicare cost reports, SIMS, and

OSCAR for years 2004-2006 to assist us in determining

Page 49970

what the ESRD facility-level characteristics are that best demonstrate what is a low-volume facility.

To begin our process of developing the methodology for defining a low-volume facility, we set parameters for ESRD facility size. In this explanation and throughout this section, the term `year' is established by the ESRD facility's final-settled cost report, where the final- settled cost report reports costs for 12-consecutive months. Under the initial categorization, an ESRD facility with less than 5,000 treatments per year was considered small, a ESRD facility with 5,000 to 10,000 treatments per year was considered medium, and an ESRD facility with 10,000 treatments per year or more was considered large. The average ESRD facility size is relatively close to 10,000 treatments and this threshold has been used by others, for example, MedPAC.

With the data compiled and analyzed by UM-KECC, we were interested to see the distribution of ESRD facility size across the different ESRD facility ownership types. For purposes of defining a low-volume facility, we chose to categorize all ESRD facilities into four ESRD facility ownership types; (1) Independent, (2) regional chains, (3)

Large Dialysis Organizations (LDOs), and (4) unknown ownership type. Of the hospital-based ESRD facilities, we found that 75.5 percent are independent, 10.7 percent are members of a regional chain/other category, 0.7 percent are members of an LDO, and 13.2 percent have unknown chain status. UM-KECC's comparison between ESRD facility size and ownership type, (Table 21: ESRD facility size and ownership type, 2004-2006), indicated that ownership varies with ESRD facility size and smaller ESRD facilities, especially those with less than 3,000 treatments, are relatively more likely to be independent than larger

ESRD facilities. For example, 31 percent of ESRD facilities with less than 3,000 treatments are independent while only 18 percent of ESRD facilities with more than 10,000 treatments are independent.

TIFF OMITTED TP29SE09.087

BILLING CODE 4120-01-C

UM-KECC's comparison also indicated that while smaller ESRD facilities are less likely to be members of an LDO than larger ESRD facilities, a relatively large fraction of smaller ESRD facilities are members of an LDO. For an example, 61.4 percent of ESRD facilities with less than 5,000 treatments and 41.9 percent of ESRD facilities with less than 2,000 treatments are members of an LDO. As a result of the comparison between ESRD facility size and ESRD facility ownership type, we chose to use ESRD facility ownership type as a variable in a two- equation regression analysis to test whether cost varies by ESRD facility ownership type within a ESRD facility size category.

With the data analyzed by UM-KECC, we were also interested to see the distribution of ESRD facility size across ESRD facilities that have an urban or rural status. UM-KECC`s comparison of ESRD facility size and urban/rural status, (Table 22: ESRD facility size and rural status, 2004-2006 (n=11,814)), indicated that nearly half of the small ESRD facilities are rural and larger ESRD facilities are less likely to be rural.

2, and 4 discussed above.

We request public comment on the potential approaches set forth above for estimating the imputed MAP amounts of renal dialysis service drugs proposed for inclusion in the ESRD PPS bundle that currently are covered under Part D. We are also interested in any other potential data sources for estimating the imputed MAP amount of those ESRD- related drugs currently paid under Part D. ii. Determining Imputed Per Treatment ESRD Outlier Services MAP Amount

ESRD facilities currently submit claims on a monthly basis that identify line item dates of service. For purposes of determining whether an ESRD facility would be eligible for an outlier payment, it would be necessary for the ESRD facility to identify the actual ESRD outlier services furnished to the patient. Specifically, we are proposing that the ESRD facility would identify by line item on the monthly claim, all ESRD outlier services furnished to the patient. We would then estimate the imputed MAP amount for these services applying one of the proposed methodologies discussed above in section X.A.1. c. i. The imputed outlier services MAP amounts for each of these services would be aggregated and then divided by the corresponding number of treatments identified on the claim to yield the imputed outlier services MAP amount per treatment. An ESRD facility would be eligible for an outlier payment if the imputed average outlier services

MAP amount per treatment exceeds the sum of the predicted, outlier services MAP amount per treatment and the fixed dollar loss amount, as described below. d. Outlier Percentage and Fixed Dollar Loss Amounts

As discussed in section VII.D.a, we are proposing that payments under section 1881(b)(14)(D)(ii) of the Act for outlier cases be applied in a budget

Page 49993

neutral manner. Therefore, to ensure that the proposed outlier policy under the ESRD PPS is budget neutral, we propose to reduce the base rate by the proposed outlier percentage, or the percentage of total

ESRD PPS payments that are intended for payment of outlier cases, as defined in proposed Sec. 413.220(b)(4).

Using an outlier loss sharing percentage of 80 percent (which is discussed in the following section), we considered various percentages from 1 percent to 3 percent of aggregate payments and the fixed dollar loss amount that is computed from these two factors. (As discussed below, we are proposing separate fixed dollar loss amounts for the pediatric and adult populations.) The appropriate outlier amount was determined by comparing the predicted outlier services MAP amount

(which, for the reasons explained previously was limited to items and services that were separately billable under Medicare Part B), for the treatment plus the fixed dollar loss amount to the imputed per treatment ESRD outlier services MAP amount. For example, using an outlier percentage of 1 percent, if the total outlier payment amount for all providers was determined to be higher or lower than 1 percent of the total payments under the proposed ESRD PPS, then the fixed dollar loss amount was adjusted accordingly. This was done in an iterative fashion until the fixed dollar amount produced total outlier payment amounts for all ESRD facilities equal to 1 percent of total payments. We applied a similar process to identify the fixed dollar loss amount associated with other outlier percentages.

We analyzed outlier percentages from 1 to 3 percent of total ESRD

PPS payments and the corresponding fixed dollar loss amounts and percentage of patient months qualifying for outlier payments, which are presented in Table 37.

Martha's BSA is calculated as:

Page 49994

BSAMartha = 0.00718 * 167.64.725* 105.425

= 0.007184 * 40.9896 * 7.2278

= 2.1284

As identified in table 29, the separately billable multiplier for

BSA would be 1.033. Martha's case-mix adjustment based on her BSA of 2.1284 would be:

= 1.033 (2.1284-1.87/0.1)= 1.088

= 1.033 2.584

= 1.088

Step 1: Determine the predicted, ESRD outlier services MAP amount.

The product of the patient-level outlier services case-mix adjusters as identified in table 34:= 66 year old: 1.006, female: 1.149, BSA: 1.088, HIV/AIDS: 1.220, septicemia: 1.715, and hereditary hemolytic or sickle cell anemias: 1.179

= 1.006 * 1.149 * 1.088 * 1.220 * 1.715 * 1.179

= 3.10231

The adjusted, average, ESRD outlier services MAP amount

= $64.54

The adjusted, average ESRD outlier services MAP amount * product of the outlier services case-mix adjusters:

=$64.54 * 3.10231

= $200.22

Step 2: Determine the imputed average, per treatment, ESRD outlier services MAP amount.

The imputed monthly ESRD outlier services amount = $4000

The corresponding total number of treatments = 10

The imputed, average, per treatment, outlier services MAP amount =

= $4000/10

= $400

Step 3: Add the fixed dollar loss amount to the predicted, ESRD outlier services MAP amount.

The fixed dollar loss amount = $134.96

The predicted, ESRD outlier services MAP amount = $200.22

= $200.22 + $134.96

= $335.18

Step 4: Calculate outlier payment.

Outlier payment = imputed average, per treatment, outlier services

MAP amount--(predicted, ESRD outlier services MAP amount plus the fixed dollar loss amount) * loss sharing percentage:

= ($400 - $335.18) * .80

= $64.82 * .80

= $51.22

Hypothetical Example--Pediatric Patient:

John, a 13 year old hemodialysis pediatric patient with 1 or more co-morbidities.

Step 1: Determine the predicted, ESRD outlier services MAP amount.

As identified in table 35, the patient-level ESRD outlier services case-mix adjuster:

=13 year old hemodialysis patient with 1 or more co-morbidities

= 1.272

The adjusted, average, ESRD outlier services MAP amount = $64.54

The adjusted, average, ESRD outlier services MAP amount * the product of the outlier services case-mix adjusters:

= $64.54 * 1.272

= $80.09

Step 2: Determine the imputed, average, per treatment, ESRD outlier services MAP amount.

The imputed monthly ESRD outlier services amount = $4000

The corresponding total number of treatments = 10

The imputed, average, per treatment, outlier services MAP amount =

= $4000/10

= $400

Step 3: Add the fixed dollar loss amount to the predicted, ESRD outlier services MAP amount.

The fixed dollar loss amount = $174.31

The predicted, ESRD outlier services MAP amount = $80.09

= $80.09 + $174.31

= $254.40

Step 4: Calculate outlier payment.

Outlier payment = imputed, average, per treatment, outlier services

MAP amount - (predicted, ESRD outlier services MAP amount plus the fixed dollar loss amount) * loss sharing percentage:

= ($400 - $254.40) * .80

= $145.60 * .80

= $116.48

The outlier payment amount would be added to the ESRD PPS payment amount, per treatment. For a detailed description of calculating the

ESRD PPS payment amount per treatment, please refer to the hypothetical examples in section XI. of this proposed rule. 4. Application of Outlier Policy During the Transition and in Relation to the ESA Monitoring Policy

As discussed in section XIII. A. of this proposed rule, section 1881(b)(14)(E)(i) of the Act requires the Secretary to provide a four- year transition from the current basic case-mix adjusted composite payment system to the ESRD PPS for renal dialysis services furnished beginning January 1, 2011. Under the transition, ESRD facilities would receive a blended rate based in part on the payment rates under the current basic case-mix adjusted composite rate payment system and in part on the payment rates under the ESRD PPS. Section 1881(b)(14)(E)(ii) of the Act permits ESRD facilities to make a one- time election to be excluded from the transition from the current case- mix adjusted composite payment system to the ESRD PPS. Those ESRD providers and facilities that elect to be excluded from the transition would receive payments for renal dialysis services provided on or after

January 1, 2011 based on 100 percent of the payment rate under the ESRD

PPS, rather than a blended rate.

As indicated above, the current ESRD basic case-mix adjusted composite payment system does not provide for outlier payments. Rather, the proposed outlier payment policy would be limited to the proposed

ESRD PPS. We therefore propose that for those ESRD facilities that do not elect to be excluded from the 4-year transition, outlier payments would be limited to the portion of the blended rate based on the payment rates under the proposed ESRD PPS.

Nothing within this proposed outlier payment policy would replace the claims monitoring implications related to the utilization of separately billable erythropoiesis-stimulating agents (ESAs) including currently available epoetin alfa (EPOGEN[supreg], or EPO), darbepoetin alfa (ARANESP[supreg]) or any ESAs that may be developed in the future and used by beneficiaries receiving renal dialysis services. As we discuss in section XIV.B of this proposed rule, we are evaluating the extent to which we could continue to apply the ESA Monitoring Policy under the proposed ESRD PPS. We are also considering ways in which outlier payments would be computed under the proposed ESRD PPS. We believe that any dosing reductions associated with the application of the ESA Monitoring Policy would be factored in prior to determining eligibility for outlier payment.

We expect that ESRD facilities would exercise prudent clinical judgment in prescribing ESAs for patients who are resistant to these drugs, so as not to over-prescribe with the intent of capitalizing on outlier payments. However, we request public comments that would outline additional safeguards to protect against overuse of ESAs among the ESA-resistant patient population.
Comprehensive Payment Model Examples

In section VIII., we demonstrated how the case-mix adjustments based on separate estimating equations for CR and SB services (that is, the two equation model), were combined to obtain a single payment formula under

Page 49995

the proposed ESRD PPS. Table 29 in that section contained the proposed case-mix adjustments applicable to adult patients. In section IX, we presented our proposed pediatric payment model under the ESRD PPS.

Table 33 in that section contained the pediatric classification categories and corresponding case-mix adjusters which we propose to apply to pediatric ESRD patients. In this section, we explain how the area wage index and the case-mix adjustments would be applied to the proposed base rate described in section VII. reflecting combined CR and

SB services, resulting in a patient-specific per treatment payment amount under the proposed ESRD PPS, as set forth in proposed Sec. 413.215. We demonstrate how the proposed case-mix adjustments presented in Tables 29 and 33 would be applied for 7 hypothetical ESRD patients to obtain the per treatment payment amounts under the ESRD PPS. The product of the applicable case-mix adjustment factors is the patient multiplier or PM. The ESRD PPS case-mix adjusters are shown in Table 29 for adult patients and Table 33 for pediatric patients. Each example uses the base rate of $198.64, covering Part B renal dialysis services and self-care home dialysis services as set forth under section 1881(b)(4) of the Act. Each example also assumes an ESRD wage index value of 1.1000. Therefore, our starting point in each example prior to determining the patient-specific PM is a wage index adjusted base rate of $206.22. This amount was computed as follows:

Base rate $198.64

Labor-related share of base rate

($198.64 * .38160 = $75.80) 75.80

Wage index adjusted labor-related share

($75.80 * 1.1000) = $83.38 83.38

Non labor-related share of base rate

($198.64 * (1 - 0.38160) = $122.84 122.84

Wage index adjusted base rate

($83.38 + $122.84) = $206.22 $206.22

(The labor-related and non labor-related shares of the base rate (that is, 38.160 percent and 1-0.38160 or 61.840 percent, respectively, represent the labor-related and non labor-related components of the bundled ESRD PPS market basket, described in section XII. of this proposed rule.)

Example 1--Relatively Healthy ESRD Patient With no Co-morbidities; no

Outlier Payments Apply

John, a 45 year old male Medicare beneficiary, is 187.96 cm.

(1.8796 m.) in height and weighs 95 kg. John was diagnosed with ESRD in early 2009 and has been on HD since August 2009. He has chronic glomerulonephritis and hypertension, and has an AV fistula. The patient also has secondary hyperparathyroidism.

Table 29 reveals that none of John's co-morbidities is among those for which a case-mix adjustment applies. The only pertinent factors to adjust the base rate amount are age, height, and weight. Using the formula for BMI, we see that John is not underweight, having a BMI of 26.89 kg/m\2\, which is greater than the threshold value of 18.5, the cut-off for underweight status:

BMI = weightkg/height (m\2\)

= 95/1.8796\2\

= 95/3.5329

= 26.89

Therefore, there is no case-mix adjustment for low BMI. The formula for calculation of a patient's BSA is:

BSA = 0.007184 * heightcm\.725\ * weightkg\.425\

John's BSA is calculated as:

BSAJohn = 0.007184 * 187.96\.725\ * 95\.425\

= 0.007184 * 44.5346 * 6.9268

= 2.2161

Using the Table 29 multiplier of 1.034, John's case-mix adjustment based on his BSA of 2.2161 is computed as follows:

PmtMultBSA = 1.034(2.2161-187)/0.1

= 1.0343.461

= 1.1227

John's PM would reflect the applicable case-mix adjustments from

Table 29 for both age and BSA and may be expressed as:

PM = PmtMultage * PmtMultBSA

= 1.000 * 1.1227

= 1.1227

The ESRD PPS payment rate per treatment would be:

$206.22 * 1.1227 = $231.52

Example 2--Same as Example 1, Except Dialysis Began November 15, 2010

John's PM would have to include the adjustment for the onset of dialysis because the treatments for which we are calculating the payment amount occur within 4 months of November 15, 2010. This particular adjustment would continue to apply for treatments furnished between January 1, 2011 and March 15, 2011. The applicable case-mix adjustments would be for a patient new to dialysis, age, and BSA, and may be expressed as:

PM = PmtMultDialOnset * PmtMultage * PmtMultBSA

= 1.473 * 1.000 * 1.1227

= 1.6537

The ESRD PPS payment rate per treatment would be:

$206.22 * 1.6537 = $341.03

Example 3--Same as Example 1, with outlier payments. (For a description of the outlier payment methodology, see section X.)

John normally receives HD 3 times weekly. However, in January 2011 he suffered a compound ankle fracture and was hospitalized for 5 days.

During the hospitalization John did not undergo any dialysis treatments. After John was discharged and he resumed receiving outpatient dialysis, it was noted that John's dialysis clinical indicators were depressed, requiring additional laboratory testing and above average doses of several injectable drugs, particularly EPO[reg], to bring them to normal levels. During January, John, who received HD at his usual facility, received only 9 treatments. The facility submitted a bill for allowable total SB drugs and biologicals, laboratory tests, and supplies for January totaling $3000.00.

John's dialysis facility would receive $231.52 for each of the 9 treatments it furnished. The SB MAP per treatment averaged $3000.00/9 or $333.33 per session. We first determine if John's dialysis facility would be entitled to outlier payments:

Using Table 29 we compute the predicted SB MAP per treatment based on SB case-mix adjustments for BSA and age.

BSA PmtMultSB = 1.033 (2.2161-1.87)/0.1

= 1.033 \3.461\

= 1.1189

Age PmtMultSB = 1.000

PMSB = 1.1189 * 1.000 = 1.1189

SB MAP per treatment (see section X.A.1.b) $64.54

The case-mix adjusted predicted SB MAP is:

$64.54 * 1.1189 = $72.21

The fixed dollar loss amount for the predicted SB MAP, reflecting the case-mix adjustments for BSA and age, becomes:

$72.21 + $134.96 = $207.17

Because John's average SB MAP for services furnished was $333.33, which exceeds the case-mix adjusted fixed dollar loss amount of

$207.17, John's ESRD facility is eligible for outlier payments beyond the otherwise applicable $231.52 ESRD PPS amount. The outlier payments are computed as follows:

Amount in excess of fixed dollar loss amount

($333.33--$207.17) = $126.16

Loss sharing ratio 80%

Outlier payments per treatment

($126.16 * .80) = $100.93 $100.93

Page 49996

Outlier payments

($100.93 * 9 treatments) = $908.37

The total ESRD payments to this facility on behalf of John for

January would be:

Regular ESRD payments

$231.52 * 9 = $2083.68

Outlier payments 908.37

Total payments $2992.05

Example 4--ESRD Patient With Multiple Co-morbidities

Mary, a 66 year old female, is 167.64 cm. in height and weighs 105 kg. She has diabetes mellitus, a history of chronic Hepatitis B, parathyroidism, and liver cirrhosis. She was diagnosed with ESRD in 2005, esophageal varices in 2006, and had a diagnosis of upper gastrointestinal (GI) bleeding in January 2011. Mary receives HD at an

ESRD facility which qualifies for the low volume adjustment. We will not repeat the calculation for BMI in this example. Suffice it to say that this patient does not have a BMI less than 18.5 kg/m\2\, the required threshold for underweight status. Table 29 reveals that the PM in this example must be calculated to reflect the case-mix adjustments for gender, BSA, Hepatitis B, and upper GI bleeding, as well as a facility low volume adjustment. The formula for calculation of a patient's BSA is:

BSA = 0.007184 * heightcm\.725\ * weightkg\.425\

Mary's BSA is calculated as:

BSAMary = 0.00718 * 167.64\.725\ * 105\.425\

= 0.007184 * 40.9896 * 7.2278

= 2.1284

Based on the Table 29 multiplier of 1.034, Mary's case-mix adjustment based on her BSA of 2.1284 would be:

PmtMultBSA = 1.034 (2.1284-1.87)/0.1

= 1.034 \2.584\

= 1.0902

Mary's PM, including application of the low volume payment adjuster, may be expressed as:

PM = PmtMultgender * PmtMultBSA * PmtMultHepB * PmtMultGIBleed *

PmtMultLV

= 1.132 * 1.0902 * 1.089 * 1.316 * 1.202

= 2.1259

The ESRD PPS payment rate per treatment applicable to Mary would be:

$206.22 * 2.1259 = $438.40

Example 5--Aged ESRD Patient With Low BMI ((1.4404-1.87)/0.1

=1.034 (-4.296)

= .8662

Agnes's PM would reflect the applicable case-mix adjustments from

Table 29 for age, gender, BSA, low BMI, and cardiac arrest. It may be expressed as:

M = PmtMultage * PmtMultgender * PmtMultBSA * PmtMultBMI *

PmtMultCardArrest

= 1.076 * 1.132 * .8662 * 1.020 * 1.032

= 1.1106

The ESRD PPS payment rate per treatment for Agnes would be:

$206.22 * 1.1106 = $229.03

Example 6--Pediatric ESRD Patient With 2 Co-morbidities; no Outlier

Payments Apply

Jonathan, a 24-month old male, began dialysis 8 months ago due to autosomal recessive polycystic kidney disease. Jonathan inherited HIV/

AIDS from his mother, who has a history of drug abuse. Jonathan also has diabetes. The patient undergoes PD, with the assistance of a cycler.

Table 33 reveals that Jonathan has two qualifying co-morbidities, diabetes and HIV/AIDS. Because Jonathan is less than 13 years old, and undergoes PD, his pediatric classification group is category 2, for which the PM is 0.980. Jonathan's ESRD PPS payment rate per treatment would be:

$206.22 * 0.980 = $202.10

For as long as Jonathan is on PD, his treating dialysis facility would receive 3 times $202.10 or $606.30 weekly.

Example 7--Pediatric ESRD Patient With 1 Co-morbidity; Outlier Payments

Apply. (For a Description of the Outlier Payment Methodology, See

Section X.)

Timmy is a 16 year old male with ESRD due to renal hypoplasia. The patient was on PD until 2005, when he received a deceased donor kidney transplant. Timmy's transplant failed in August 2007, and he has been on HD since that time. The patient receives dialysis through an AV fistula. Timmy has a history of post-transplant lymphoma, which is in remission. He also has diabetes mellitus, which developed after the kidney transplantation. Timmy weighs 66.2 kg. and is 161.6 cm in height. He was hospitalized one month ago with Klebsiella bacteremia.

As part of his HD, Timmy receives Aranesp[reg] 60 mcg. IV q 2 weeks, paracalcitol 4 mcg. IV 3 times a week, and iron dextran 100 mg. IV every 2 weeks. The patient also takes 2 tablets (667 mg. each) of calcium acetate 3 times per day. Timmy had 12 HD treatments in January 2011. The facility submitted a bill for allowable SB drugs and biologicals, laboratory tests, and supplies totaling $3250.00.

Table 33 reveals that Timmy has 1 qualifying co-morbidity, diabetes. Because Timmy is 16 and undergoes HD, his pediatric classification group is category 8, for which the PM is 1.215. Timmy's payment rate per treatment, without regard to outlier payments, would be:

$206.22 * 1.215 = $250.56

Timmy's dialysis facility would receive $250.56 for each of the 12 treatments it furnished in January. Based on the total allowable billed

SB services of $3250, the SB MAP per

Page 49997

treatment averaged $3250/12 or $270.83 per session. We must determine if Timmy's dialysis facility would be eligible for outlier payments.

Using Table 33, we must calculate the case-mix adjusted predicted

SB MAP. (See section X.A.1.b)

SB MAP * PmtMult = $64.54 * 1.272 = $82.09

The fixed dollar loss amount for the predicted SB MAP is:

$82.09 + $174.31 = $256.40

Because Timmy's average SB MAP for services furnished was $270.83, which exceeds the case-mix adjusted fixed dollar loss amount of

$256.40, Timmy's ESRD facility is eligible for outlier payments beyond the otherwise applicable $250.56 ESRD PPS amount. The outlier payments are computed as follows:

Amount in excess of fixed dollar loss amount

($270.83--$256.40) = $14.43

Loss sharing ratio 80%

Outlier payments per treatment

($14.43 * .80) = $11.54 $11.54

Outlier payments

($11.54 * 12) = $138.48 $138.48

The total ESRD payments to this facility on behalf of Timmy for

January would be:

Regular ESRD payments

($250.56 * 12) = $3006.72 $3006.72

Outlier payments 138.48

Total payments $3145.20
ESRD Bundled Market Basket

Under section 1881(b)(14)(F)(i) of the Act, as added by section 153(b) of MIPPA, beginning in 2012, the ESRD bundled payment amounts are required to be annually increased by an ESRD market basket increase factor minus 1.0 percentage point. The statute further provides that the market basket increase factor should reflect the changes over time in the prices of an appropriate mix of goods and services used to furnish renal dialysis services. As noted in section VII.B of this proposed rule, under section 1881(b)(14)(F)(ii) of the Act, the ESRD bundled rate market basket will also be used to update the composite rate portion of ESRD payments during the PPS phase-in period from 2011 through 2013.

As required under section 1881(b)(14) of the Act, effective for CY 2012, CMS has developed an all inclusive ESRD bundled rate (ESRDB) input price index. Although ``market basket'' technically describes the mix of goods and services used to produce ESRD care, this term is also commonly used to denote the input price index (that is, cost categories, their respective weights, and price proxies combined) derived from that market basket. Accordingly, the term ``ESRDB market basket'' as used in this document refers to the ESRDB input price index.

A market basket has historically been used under the Medicare program to account for the price increases of the requisite inputs associated with the services furnished by providers. The percentage change in the ESRDB market basket reflects the average change in the price of goods and services purchased by ESRD facilities in providing renal dialysis services. Since we are proposing a single payment rate for both operating and capital-related costs, the proposed ESRDB market basket for ESRD facilities includes both operating and capital-related costs.

The following discussion includes an explanation of the methodology and results of the proposed ESRDB market basket. First, we describe the methodology behind the development of the proposed cost category weights. Next, we explain the basis for the selection of each price measure used to proxy the rate of price change for each expenditure or cost category. Next, we present the results of the proposed ESRDB market basket, and finally we propose our definition of the ESRDB labor-related share.

The ESRDB market basket is constructed in three steps. First, a base period is selected and total base period expenditures are estimated for a set of mutually exclusive and exhaustive spending categories. Then, the proportion of total costs that each category represents is determined. These proportions are called cost or expenditure weights. Each expenditure weight category is then matched to an appropriate price or wage variable, referred to as a price proxy.

These price proxies are price index levels derived from publicly available statistical series that are published on a consistent schedule, preferably at least on a quarterly basis. Finally, the expenditure weight for each category is multiplied by the index level of the respective price proxy to arrive at a weighted index level for each cost category. The sum of the products (that is, the expenditure weights multiplied by the price levels) for all cost categories yields the aggregate index level of the market basket in a given year.

Repeating this step for different time periods produces a series of market basket index levels over time. Dividing an index level in one period by an index level in an earlier period produces a rate of growth in the input price index over that time period.

We are proposing to use CY 2007 as the base year for the development of the ESRDB market basket cost weights. The cost weights for this proposed ESRDB market basket are based on the cost report data for independent ESRD facilities.

We refer to the market basket as a CY market basket because the base period for all price proxies and weights are set to CY 2007 = 100.

Source data included CY 2007 Medicare cost reports (Form CMS-265-94), supplemented with 2002 data from the U.S. Department of Commerce,

Bureau of the Census' Business Expenditure Survey (BES). The BES data were aged to 2007 using appropriate price proxies to estimate price growth. The price proxies used for the aging of the BES data come from publicly available price indexes such as various producer price indexes

(PPI), consumer price indexes (CPI), or employment cost indexes (ECI).

All of these price proxies are published by the U.S. Department of

Labor, Bureau of Labor Statistics (BLS). We are proposing to use CY 2007 because it is the most recent year that both relatively complete

Medicare cost report data and supplemental BES data is available.

Analysis of Medicare cost reports for CY 2002 through CY 2006 showed little difference in cost weights compared to CY 2007. Medicare cost reports from hospital-based ESRD providers were not used to construct the proposed ESRDB market basket because data from independent ESRD facilities tend to better reflect the actual cost structure faced by the ESRD facility itself, and are not influenced by the allocation of overhead over the entire institution, as can be the case with hospital- based providers. This approach is consistent with our standard methodology used in the development of other market baskets, particularly those used for updating the skilled nursing facility PPS and home health PPS.

Cost Category Weights

Using Worksheets A, A2, and B from the CY 2007 Medicare cost reports, we first computed cost shares for nine major expenditure categories: Wages and Salaries, Employee Benefits for direct patient care, Pharmaceuticals, Supplies, Laboratory Services, Blood Products,

Administrative and General and Other (A&O), Housekeeping and

Operations, and Capital-Related costs. Edits were applied to include only cost reports that had total costs greater than zero. In order to reduce potential distortions from outliers in the calculation of the cost weights for the major expenditure categories, cost values for each category less than the 5th percentile or greater than the 95th percentile were excluded from the

Page 49998

computations. The resulting data set included information from approximately 3,572 independent ESRD facilities' cost reports from an available pool of 3,970 cost reports. Expenditures for the nine cost categories as a proportion of total expenditures are shown in Table 38.

GRAPHIC

TIFF OMITTED TP29SE09.009

Some costs that are required to be included in the ESRD bundled payment are not reported on the Medicare cost report. As a result, we supplemented Medicare cost report data with expenditure estimates for various ESRD-related drugs currently covered by Medicare Part D, as well as with additional lab expenses. The estimates for both of the aforementioned expenditures were provided by KECC. There are also costs that are reported on the Medicare cost report, but are not included in the ESRD bundled payment. As a result, we removed the expenses related to vaccine costs from total expenditures since these are excluded from the ESRD bundled payment, but reported on the Medicare cost report.

We are proposing to expand the expenditure categories developed from the Medicare cost reports to allow for a more detailed expenditure decomposition. To expand these cost categories, BES data were used as the Medicare cost reports do not collect detailed information on the items in question. Those categories include: benefits for all employees, professional fees, telephone, utilities, and all other services. We chose to separately break out these categories to more accurately reflect changes in ESRD facility costs. We describe below how the initially computed categories and weights were modified to yield the final ESRDB market basket expenditure categories and weights presented in this proposed rule.

Wages and Salaries

The weight for wages and salaries for direct patient care that was initially computed was derived from Worksheet B of the Medicare cost report. However, because Worksheet B only includes direct patient care salaries, it was necessary to derive a methodology to include all salaries, not just direct patient care salaries, in order to calculate the appropriate market basket cost weight. This was accomplished in the following steps.

(1) From the trial balance of the cost report (Worksheet A), we computed the ratio of salaries to total costs in each cost center. The cost centers for which we calculated this ratio were drugs, housekeeping and operations, A&O, supplies, blood and blood products, laboratories, capital-related machinery, and EPO.

(2) We then multiplied the ratios computed in step 1 by the total costs for each corresponding cost center from Worksheet B. This provided us with an estimate of non-direct patient care salaries for each cost center.

(3) The estimated non-direct patient care salaries for each of the cost centers on Worksheet B estimated in step 2 were subsequently summed and added to the direct patient care salary figure (resulting in a new total salaries figure).

(4) The estimated non-direct patient care salaries (see step 2) were then subtracted from their respective cost categories to avoid double-counting their values in the total costs.

As a result of this process, we moved from an estimated Wages and

Salaries cost weight of 20.965 percent (as estimated using only direct patient care salaries as a percent of total costs found on the Medicare cost report) to a weight of 25.106 percent (capturing both direct and non-direct patient care salaries and, again, dividing that by total costs found on the Medicare cost report), as seen in Table 38.

When we add the expenditures related to lab expenses that were previously paid for under the Medicare fee schedule and not included in the Medicare cost report and the ESRD-related drug expenditures currently covered under Part D that were not included in the Medicare cost report, and remove the estimated vaccine costs that are to be paid outside of the bundle, then the cost weight for the Wages and Salaries category falls to 22.798 percent.

The final adjustment made to this category is to include contract labor costs. These costs appear on the Medicare cost report, however, they are embedded in the Administrative and General and Other category and cannot be disentangled using the Medicare cost reports alone. To move the appropriate expenses from the A&O category to Wages and

Salaries, we used data from the BES. We first summed total contract labor costs in the survey. We then took 80 percent of that figure and added it to Wages and Salaries. At the same time, we subtracted that same amount from A&O. The 80 percent figure that was used was determined by taking salaries as a percentage of total compensation

(excluding contract labor). The resulting cost weight for Wages and

Salaries increases to 24.516 percent.

Benefits

The Benefits weight was derived from the 2002 BES data aged forward to 2007 as a benefit share for all employees is not available from the

ESRD Medicare cost report. The cost report only reflects benefits for direct patient care. In order to include the benefits related to non-

Page 49999

direct patient care, we estimated this marginal increase from the BES

Benefits weight. This resulted in a Benefits weight that was 0.672 percentage point larger (5.748 vs. 5.076) than the Benefits weight for direct patient care calculated directly from the cost reports. To avoid double-counting and to ensure all of the market basket weights still totaled 100 percent, we removed this additional 0.672 percentage point for Benefits from Pharmaceuticals, Biological Products, Administrative and General and Other, Supplies, Laboratory Services, Housekeeping and

Operations, and the Capital-related Machinery components. This calculation reapportions the benefits expense for each of these categories using a method similar to the method used for distributing non-direct patient care salaries as described above.

The final adjustment made to this category is to include contract labor costs. Once again, these costs appear on the Medicare cost report, however, they are embedded in the Administrative and General and Other category and cannot be disentangled using the Medicare cost report alone. To move the appropriate expenses from the A&O category to

Benefits, we followed the same methodology used to apportion contract labor wages and salaries noted immediately above. For Benefits, we applied the remaining 20 percent of total contract labor costs, as estimated using the BES, and included that in the Benefits cost weight.

At the same time, we subtracted that same amount from A&O. The 20 percent figure that was used was determined by summing direct patient care benefits (as estimated using the Medicare cost report) and non- direct patient care benefits (as estimated using the BES) and taking that sum as a percentage of total compensation (excluding contract labor). The resulting cost weight for Benefits increases to 6.177 percent.

Utilities

We developed a weight for Utility expenses using the 2002 BES data, as utilities are not separately identified on the Medicare cost report.

We aged the 2002 utility expenditures to 2007. We then disaggregated the Utilities category to reflect three subcategories: Electricity,

Fuel (natural gas), and Water and Sewerage. We computed the ratio of each BES category to the total BES operating expenses. We then applied each ratio to the total operating expense percentage share as calculated from the cost reports, including the additions of ESRD- related drugs currently covered under Part D and additional lab expenses, to estimate the ESRD facility weight for each utility expenditure category. These amounts were then deducted from the share of the combined Operation & Maintenance of Plant and Housekeeping cost category, where the expenses are included on the Medicare cost report

(but cannot be separately identified). The resulting Electricity, Fuel

(Natural Gas), and Water and Sewerage ESRDB market basket weights are 0.586, 0.111, and 0.483 percent, respectively, yielding a combined

Utilities cost weight of 1.180 percent.

Pharmaceuticals

The proposed ESRDB market basket includes expenditures for all drugs, including separately billable drugs and ESRD-related drugs currently covered under Medicare Part D. We were able to calculate an expenditure weight for pharmaceuticals directly from the Drugs cost center on Worksheet B plus the expenditures of EPO which are reported on worksheet A2 of the Medicare cost reports. Vaccine expenditures, which are mandated as separately reimbursable, were excluded when calculating this cost weight. Section 1842(o)(1)(A)(iv) of the Act requires that influenza, pneumococcal, and hepatitis B vaccines described in subparagraph (A) or (B) of section 1861(s)(10) of the Act be paid based on 95 percent of average wholesale price (AWP) of the drug. Since these drugs are excluded from other prospective payment systems, we exclude them from the proposed ESRDB market basket, as well. We estimate that expenditures for these three vaccines are approximately 1 percent of the total Medicare-allowable payments for separately billable drugs. 2007 expenditures for ESRD-related drugs currently covered under Part D were added to cost report totals.

Finally, to avoid double-counting, the weight for the

Pharmaceuticals category was reduced to exclude the estimated share of non-direct patient care salaries and benefits associated with the Drugs and Epoetin cost centers. This resulted in a proposed ESRDB market basket weight for Pharmaceuticals of 30.743 percent. EPO expenditures accounted for 19.351 percentage points of the Pharmaceuticals weight,

ESRD-related drugs currently covered under Part D accounted for 4.681 percentage points of the Pharmaceuticals weight, and all other drugs accounted for the remaining 6.710 percentage points of the

Pharmaceuticals weight.

Blood Products

We calculated the weight for Blood Products in the ESRDB market basket using the separately billable expenditure amounts for the Whole

Blood and Packed Red Blood Cells cost center on Worksheet A of the

Medicare cost report. We then added the expenditures for A&O for Whole

Blood and Packed Red Blood Cells from Worksheet B to the net expenses from worksheet A to arrive at a total expenditure amount for Blood

Products. This total was divided by total expenses to derive a weight for the Blood Products component in the bundled rate market basket.

Similar to other expenditure category adjustments, we reduced the computed weight to exclude non-direct patient care salaries and benefits associated with the Blood cost centers. The proposed adjusted

Blood Products market basket weight is 0.035 percent.

Supplies

We calculated the weight for Supplies included in the bundled rate using the reimbursable and separately billable expenditure amounts for the Supplies cost center on Worksheet B of the Medicare cost report.

Supplies that are separately billable are reported as a separate line item on the cost reports and were also included. This total was divided by total expenses to derive a weight for the Supplies component in the

ESRDB market basket. The computed weight for this category was reduced by the non-direct patient care salaries and benefits associated with the Supplies cost center. The resulting proposed market basket weight for Supplies is 8.543 percent.

Laboratory Services

We calculated the weight for Laboratory Services included in the bundled rate using the reimbursable and separately billable expenditure amounts for the Laboratory cost center on Worksheet B of the Medicare cost report. The cost report expenditures do not include laboratory services paid for under the Medicare fee schedule, only facility- furnished laboratory tests. Since a large majority of laboratory tests are paid via the fee schedule, we adjusted the laboratory fees upward.

The inflation factor was computed from the ratio of ESRD facility

Medicare laboratory payment data to the other facility Medicare laboratory payment data. This provides a measure of the extent to which laboratory services fall under the Medicare fee schedule. For 2007, we increased the laboratory expenditures by a factor of 16.298, as estimated by KECC. The weight for this category was similarly reduced by the non-direct patient care salaries and benefits associated with the Laboratory cost center. The resulting proposed

Page 50000

market basket weight for Laboratory Services is 4.875 percent.

Housekeeping and Operations

We developed a market basket weight for this category using data from Worksheet A of the Medicare cost reports. Worksheet B combines the capital-related costs for buildings and fixtures with the Operation and

Maintenance of Plant (Operations) and Housekeeping cost centers, so we were unable to calculate a weight directly from Worksheet B. We separated these expenses from capital-related costs because we believe housekeeping and operations expenditures, such as janitorial and building services costs, are largely service-related and would be more appropriately proxied by a service-related price index. To avoid double-counting, we subtracted from the Housekeeping and Operations weight the utilities proportion described above, as well as the non- direct patient care salaries and benefits share associated with the

Operations and Housekeeping cost center. The resulting proposed market basket weight for Housekeeping and Operations is 1.766 percent.

Administrative and General and Other (A&O)

We computed the proportion of total A&O expenditures using the A&O cost center data from Worksheet B of the Medicare cost reports minus the A&O expenditures related to the Blood Products category. As described above, we exclude contract labor from this cost category and apportion these costs to the salary and benefits cost weights. Similar to other expenditure category adjustments, we then reduced the computed weight to exclude salaries and benefits associated with the A&O cost center. The resulting A&O cost weight is 13.617 percent. This A&O cost weight is then fully apportioned to derive detailed cost weights for

Professional Fees, Telephone, All Other Labor-related Services, and All

Other Nonlabor-related Services.

Professional Fees

A separate weight for Professional Fees was developed using the 2002 BES data aged to 2007. Professional fees include fees associated with the following: Advertising, accounting, bookkeeping, legal, management, consulting, administrative, and other professional services fees. To estimate professional fees, we first calculated the ratio of

BES professional fees to a total of administrative and other expenses from BES. We applied this ratio to the A&O total cost weight to estimate the proportion of ESRD facility professional fees. The resulting weight is 1.692 percent. This proposed cost weight is then separated into Labor-related Professional Fees (1.478 percent) and

Nonlabor-related Professional Fees (0.214 percent), which is described in more detail below.

Telephone

Because telephone service expenses are not separately identified on the Medicare cost report, we developed a Telephone Services weight using the 2002 BES expenses aged to 2007. We estimated a ratio of telephone services expenses to total administrative and other expenses from BES. We applied this ratio to the total A&O cost weight to estimate the proportion of ESRD facility telephone expenses. The resulting proposed market basket cost weight for Telephone Services is 0.590 percent.

All Other Labor-related Services

A separate weight for All Other Labor-related Services was developed using the 2002 BES data aged to 2007. All other labor-related services include repair and maintenance fees. We estimated a ratio of all other labor-related services expenses to total administrative and other expenses from BES. We applied this ratio to the total A&O cost weight to estimate the cost weight for ESRD facility All Other Labor- related Services. The resulting proposed market basket cost weight is 1.163 percent.

All Other Nonlabor-related Services

A separate weight for All Other Nonlabor-related Services was developed using the 2002 BES data aged to 2007. Non labor-related services include insurance, transportation, shipping, warehousing, printing, data processing services, and all other operating expenses not otherwise classified. We estimated a ratio of all other nonlabor- related services expenses to total administrative and other expenses from BES. We applied this ratio to the total A&O cost weight to estimate the cost weight for ESRD facility All Other Nonlabor-related

Services. The resulting proposed market basket cost weight is 10.172 percent.

Capital

We developed a market basket weight for the Capital category using data from Worksheet B of the Medicare cost reports. Capital-related costs include depreciation and lease expense for buildings, fixtures, movable equipment, property taxes, insurance, the costs of capital improvements, and maintenance expense for buildings, fixtures, and machinery. Because housekeeping and operations costs are included in the Worksheet B cost center for Buildings and Fixtures capital-related expense, we excluded these costs and developed a separate expenditure category as noted above. Similar to the methodology used for other market basket cost categories with a salaries component, we computed a share for non-direct patient care salaries and benefits associated with the Capital-related Machinery cost center. We used Worksheet B to develop two capital-related cost categories, one for Buildings and

Fixtures, and one for Machinery. We reasoned this was particularly important given the critical role played by dialysis machines.

Likewise, because price changes associated with Buildings and Fixtures could move differently than those associated with Machinery, we felt that separate price proxies would be more appropriate to track price changes for the different capital-related categories over time. The resulting proposed market basket weights for Capital-related Buildings and Equipment and Capital-related Machinery are 6.653 and 1.894 percent, respectively.

Table 39 lists all of the expenditure categories in the ESRDB market basket and their corresponding CY 2007 cost weights and proxies, as developed in accordance with the methodology described above.

Price Proxies

Once we determined the proposed CY 2007 ESRDB market basket expenditure categories and weights, appropriate wage and price series or proxies were selected to measure the rate of price change for each category. All of the proxies are based on BLS data, and are grouped into one of the following three BLS categories:

PPIs--PPIs measure changes in the prices producers receive for their outputs. PPIs are the preferable price proxies for goods and services that ESRD facilities purchase as inputs in producing dialysis services, since these facilities generally make purchases in the wholesale market. The PPIs that we use measure price change at the final stage of production.

CPIs--CPIs measure changes in the prices of final goods and services purchased by the typical consumer. Because these indexes may not reflect the prices faced by a producer, we used CPIs only if an appropriate PPI was not available, or if the expenditure more closely resembled a retail rather than wholesale purchase. For example, we used the CPI for telephone services as a proxy for the Telephone cost category because there is no corresponding PPI, and we reasoned that commercial and residential rates change similarly.

ECIs--ECIs measure the rate of change in employee wage rates and employer costs for employee benefits per hour worked. They are fixed- weight indexes that strictly measure changes in wages and benefits per hour, and are not affected by shifts in employment mix.

We evaluated the price proxies using the criteria of reliability, timeliness, availability, and relevance. Reliability indicates that the index is based on valid statistical methods and has low sampling variability. Timeliness implies that the proxy is published regularly, preferably at least once a quarter. Availability means that the proxy is publicly available. Finally, relevance means that the proxy is applicable and representative of the cost category weight to which it is applied. The CPIs, PPIs, and ECIs we propose to use meet these criteria.

Wages and Salaries

We propose to use the ECI (Wages and Salaries) for Health Care and

Social Assistance Workers (Civilian) as the measure of price growth for

Wages and Salaries in the ESRDB market basket. We feel that this price proxy most closely reflects both the types of occupations employed by

ESRD facilities, and the competitive nature of the dialysis and health services labor markets.

Benefits

We propose to use the ECI for Employee Benefits for Health Care and

Social Assistance Workers (Civilian) as the measure of price growth for

Benefits in the ESRDB market basket. We selected this price proxy because it most accurately represents the labor conditions associated with ESRD facilities' employee benefit costs, similar to our finding for wages and salaries.

Professional Fees

We propose to use the ECI (Compensation) for Professional and

Related Occupations (Private) as the proxy for professional fees. We selected this price proxy because it includes occupations such as lawyers, accountants, and bookkeepers that are represented in this cost category.

Utilities

We propose to use the PPI for Commercial Electric Power and the PPI for Commercial Natural Gas as the proxies for the Electricity and

Natural Gas cost categories, respectively. We propose to use the CPI for Water and sewerage as the price proxy for the water and sewerage cost category.

Page 50002

Capital-Related--Building and Equipment

We propose to use the CPI for Residential Rent as the price proxy for the Capital-related Building and Equipment cost category. As described earlier, this cost category includes building and fixtures, leased buildings, fixed equipment, and moveable equipment. Because machine equipment, particularly dialysis machines, is reflected in a separate cost category, the bulk of the expenditures captured here are for building and fixed equipment. Thus, we would prefer to have a proxy that captures the price change associated with this type of capital expense. While there can sometimes be differences in the price levels for residential and commercial rent, we believe the CPI for Residential

Rent approximates the change in the underlying costs associated with

ESRD facilities' capital costs such as depreciation, interest, taxes, and other capital costs. Given the lack of an ESRD-specific proxy for capital costs, we believe that the CPI for Residential Rent represents an adequate proxy for the changes in capital costs facing ESRD facilities.

Capital-Related--Machinery

We propose to use the PPI for Electrical Machinery and Equipment as the price proxy for the Capital-related Machinery cost category. This

PPI includes dialysis machines, which are a significant component of machine equipment costs reported by ESRD facilities. Therefore, we believe that this price proxy is the best measure of the price growth of this cost category.

Pharmaceuticals

ESRD facilities use a variety of drugs during dialysis treatment including EPO which is currently a separately billable drug and accounts for the majority of ESRD facility drug expenses. We pay for erythropoietic agents to treat chronic anemia in ESRD patients. At present, Epogen[ssscopy] and Aranesp[ssscopy] (both manufactured by a single supplier) are two of the prevailing erythropoietic drugs available to treat anemia in ESRD patients. Medicare is the dominant purchaser of EPO since it is mainly used to treat kidney dialysis patients.

For the proposed ESRDB market basket, we propose to use the PPI for

Prescription Drugs as the price proxy for the Pharmaceuticals category.

We propose the use of this proxy for a variety of reasons. First, all of the market baskets that we produce include price proxies that are intended to reflect the efficient average price increase associated with the purchase of the particular input category. Accordingly, we have chosen to proxy the Pharmaceuticals cost category in the proposed

ESRD market basket, which includes the mix of all prescription drugs purchased by dialysis facilities, by the PPI for Prescription Drugs because it reflects price changes associated with the average mix of all pharmaceuticals in the overall economy. Second, we anticipate the price changes associated with the assortment of drugs administered in

ESRD facilities should, over time, be similar to the average prescription drug price changes observed across the entire economy.

Finally, this price series was chosen as it is both publicly available and regularly published.

Blood Products

We propose to use the industry PPI for Blood and Organ Banks as the price proxy for this cost category. This is the price proxy that we recently proposed to use in the 2006-based inpatient hospital market basket (74 FR 24157).

Supplies

We propose to use the commodity-based PPI for Medical, Surgical, and Personal Aid Devices as a proxy for changes in ESRD supply prices.

Many of the supplies used in dialysis are included in this PPI, such as dialyzers, catheters, I.V. equipment, syringes, and other general medical supplies used in dialysis treatment.

Laboratory Services

We propose to use the PPI for Medical Laboratories as the price proxy for the ESRD Laboratory Services cost category. Most of the laboratory tests used in dialysis are blood chemistry tests (a covered component of the medical labs PPI). Additionally, some ESRD facilities are using diagnostic imaging services to monitor patient site access, and the points where waste exchange takes place (also a covered component of the medical labs PPI).

Telephone

We propose to use the CPI for Telephone Services as the price proxy for the Telephone cost category. This index is used as the price proxy for Telephone Services in other market baskets produced by CMS.

Housekeeping and Operations

We propose to use the PPI for Building Cleaning and Maintenance

Services as the price proxy for the Housekeeping and Operations cost category. This PPI includes housekeeping, janitorial, and maintenance

(excluding repairs) services, and is representative of the types of costs included in this cost category.

All Other Labor-Related Services

We propose to use the ECI (compensation) for Service Occupations

(Private) as the price proxy for the All Other Labor-related Services cost category. This category includes expenses related to repair services. We feel that the service occupations most accurately reflect the costs for these types of repair and maintenance services purchased by ESRD facilities.

All Other Nonlabor-Related Services

We propose to use the CPI for All Items Less Food and Energy as the price proxy for the All Other Nonlabor-related Services cost category.

This category includes costs such as data processing, purchasing, taxes, home office costs, and malpractice costs. The costs represented in this category are diverse and are primarily associated with the purchase of services. These costs are best represented by a general measure of inflation such as the CPI for All Items Less Food and

Energy. Food and energy are excluded from the index to remove the volatility associated with those items. Additionally, energy prices are already captured in the utility price proxies.

ESRDB Market Basket Increases

The proposed ESRDB market basket reflects the combination of weights and proxies discussed above. Table 40 contains the forecasted rate of growth for CY 2009 through CY 2019 for the ESRDB market basket.

Over this time period, the ESRDB market basket average increase is projected to be 2.7 percent.

ESRD Labor-Related Share

The labor-related share of a market basket is determined by identifying the national average proportion of operating costs that are related to, influenced by, or vary with the local labor market. The labor-related share is typically the sum of Wages and Salaries,

Benefits, Professional Fees, Labor-related Services, and a portion of the Capital share from a given market basket.

We used the 2007-based ESRDB market basket costs to determine the proposed labor-related share for ESRD facilities under a bundled system. Under the proposed ESRDB market basket, the labor-related share for ESRD facilities is 38.160 percent; as shown in Table 41 below.

These figures represent the sum of Wages and Salaries, Benefits,

Housekeeping and Operations, All Other Labor-related Services, 87 percent of the weight for Professional Fees (details discussed below), and 46 percent of the weight for Capital-related Building and Equipment expenses (details discussed below).

The labor-related share for Professional Fees (87 percent) reflects the proportion of ESRD facilities' professional fees expenses that we believe varies with local labor market. We recently conducted a survey of ESRD facilities to better understand the proportion of contracted professional services that ESRD facilities typically purchase outside of their local labor market. These purchased professional services include functions such as accounting and auditing, management consulting, engineering, and legal services. Based on the survey results, we determined that, on average, 87 percent of professional services are purchased from local firms and 13 percent are purchased from businesses located outside of the ESRD's local labor market. Thus, we are proposing to include 87 percent of the cost weight for

Professional Fees in the labor-related share.

The labor-related share for capital-related expenses (46 percent of

ESRD facilities' adjusted Capital-related Building and Equipment expenses) reflects the proportion of ESRD facilities' capital-related expenses that we believe varies with local labor market wages. Capital- related expenses are affected in some proportion by variations in local labor market costs (such as construction worker wages) that are reflected in the price of the capital asset. However, many other inputs that determine capital costs are not related to local labor market costs, such as interest rates. The 46-percent figure is based on regressions run for the inpatient hospital capital PPS in 1991 (56 FR 43375). We use a similar methodology to calculate capital-related expenses for the labor-related shares for rehabilitation facilities (70

FR 30233), psychiatric facilities, long-term care facilities, and skilled nursing facilities (66 FR 39585).
Proposed Implementation for the ESRD PPS
1. Transition Period
  
  Section 1881(b)(14) of the Act replaces the current basic case-mix adjusted composite payment system with a case-mix adjusted bundled prospective payment system, or the ESRD PPS, for Medicare outpatient
  
  ESRD facilities beginning January 1, 2011. Section 1881(b)(14)(E)(i) of the Act requires the Secretary to provide ``a four-year phase-in'' of the payments under the ESRD PPS for renal dialysis services furnished on or after January 1, 2011. Although the statute uses the term
  
  ``phase-in'', other Medicare payment systems use the term
  
  ``transition'' to describe the timeframe during which payments are based on a blend of the payment rates under the prior payment system and the new payment system. For purposes of this ESRD PPS proposed rule, we will use the term ``transition'' to describe this timeframe.
  
  Section 1881(b)(14)(E)(i) of the Act further requires that the transition occur ``in equal increments,'' with payments under the ESRD
  
  PPS ``fully implemented for renal dialysis services furnished on or after January 1, 2014.'' In addition, section 1881(b)(14)(E)(ii) of the
  
  Act permits an ESRD facility to make a one-time election to be excluded from the transition from the current basic case-mix adjusted composite payment system, with its payment amount for renal dialysis services based entirely on the payment amount under the ESRD PPS. This election must be made prior to January 1, 2011. In addition, section 1881(b)(14)(E)(iii) of the Act requires that we make an adjustment during the transition so that payments during the transition equal the estimated total amount of payments that would otherwise occur under the
  
  ESRD PPS without such a transition. The transition budget-neutrality adjustment is discussed further in section VII.E.
  
  In accordance with section 1881(b)(14)(E) of the Act, we propose to implement the transition from the current basic case-mix adjusted composite payment system in equal increments, with renal dialysis services and home dialysis furnished on or after January 1, 2014, paid entirely based on the payment amount under the ESRD PPS. Specifically, we propose that for renal dialysis services and home dialysis services provided during the transition period beginning January 1, 2011 and ending December 31, 2013, ESRD facilities receive a blended payment for each dialysis treatment consisting of the payment amount under the basic-case mix adjusted composite system and the payment amount under the ESRD PPS. Therefore, because ESRD facilities would receive an all- inclusive payment during the transition for all renal dialysis services and home dialysis items and services, other entities, such as Method II
  
  DME suppliers, laboratories, and Part D plans would no longer bill
  
  Medicare beginning January 1, 2011. To the extent these entities furnish items or services to ESRD patients, the entities would need to seek payments from the patient's ESRD facility. Further discussion on
  
  Method II DME suppliers, laboratories, and Part D plans can be found below.
  
  For CY 2011, we are proposing to make payments based on 75 percent of the payment rate under the basic case-mix adjusted composite payment system and 25 percent of the payment rate under the ESRD PPS. For CY 2012 we are proposing to make payment based on 50 percent of the payment rate under the basic case-mix adjusted composite payment system and 50 percent of the payment rate under the ESRD PPS. For CY 2013 we are proposing to make payment based on 25 percent of the payment rate under the basic case-mix adjusted composite payment system and 75 percent of the payment rate under the ESRD PPS. For renal dialysis services furnished on or after January 1, 2014, we propose that payment to ESRD facilities be based on 100 percent of the payment amount under the ESRD PPS.
  
  In particular, we propose that the portion of the blended rate based on the
  
  Page 50004
  
  payment amount with regard to the basic case-mix adjusted composite payment system would be comprised of the composite payment rate (which is adjusted by the basic case-mix and a wage index), the drug add-on amount, and payment amounts for items and services furnished to dialysis patients that are currently separately paid under Part B by
  
  Medicare to entities other than the ESRD facility. In addition to the above components of the basic case-mix adjusted payment system, as part of the transitional budget neutrality adjustment (describe in section
  
  VII.E.), we are also proposing to include a 14 dollar adjustment to the portion of the blended rate related to the basic case-mix adjusted payment system during the transition. The 14 dollar adjustment to the portion of the blended payment amount related to the basic case-mix adjusted payment system accounts for the ESRD related drugs and biological that are currently separately paid under Part D and are being proposed to be included in the ESRD PPS base rate.
  
  For the years during which the phase-in (transition) is applicable, section 1881(b)(14)(F)(ii) of the Act requires the Secretary to annually increase the portion of the proposed ESRD PPS that is based on the composite rate that would otherwise apply if the ESRD PPS had not been enacted. In particular, section 1881(b)(14)(F)(ii)(II) of the Act requires the composite rate portion of the blended payment to be updated annually by the ESRDB market basket minus 1.0 percentage point.
  
  Our interpretation of section 1881(b)(14)(F)(ii) of the Act is that the
  
  ESRDB market basket minus 1.0 percentage point would be applied only to the composite payment rate portion of the blended payment amount for each year of the transition (which includes CY 2011). A full description of the ESRDB market basket is presented in section XII.
  
  Therefore, for each year of the transition, we are proposing that the composite payment rate portion of the blended amount would be updated by a case-mix adjustment, the drug add-on adjustment, the current wage index, the ESRDB market basket minus 1.0 percentage point, and an adjustment to account for former ESRD-related Part D drugs to maintain transitional budget neutrality. Payments for items and services furnished to dialysis patients that are paid separately under
  
  Part B with regard to the current composite payment rate methodology, that is, ESRD-related laboratory tests, ESRD-related drugs, and ESRD- related supplies, blood, and blood products would no longer be paid separately. Instead, those items and services would be priced to reflect how they are currently paid, for example, using a fee schedule or ASP amount.
  
  We note that there are ESRD facilities that have existing exception amounts that are used for payment in lieu of the composite rate, drug add-on payment, and basic case-mix adjustments (further discussion of exceptions under the basic case-mix adjustment composite payment system can be found in section I.B.3). Any existing exception amount would not be updated by the ESRDB market basket throughout the transition.
  
  The portion of the blended rate based on the payment amount under the ESRD PPS includes the base rate and all applicable patient-level and facility-level adjustments, as would be determined under proposed
  
  Sec. 413.231 and Sec. 413.235. As set forth in proposed Sec. 413.237, we propose that the ESRD PPS portion of the blended rate would also include outlier payments.
  
  As specified in proposed Sec. 413.178, bad debt is paid separately from the ESRD PPS and any payment for bad debt would occur at the time a FI/MAC reviews an ESRD facility's cost report and makes a final determination on if there are any overpayments/underpayments due to the
  
  ESRD facility/Medicare. For more information regarding bad debt payments see section XIV.D.
  
  As previously noted, section 1881(b)(14)(E)(ii) of the Act gives an
  
  ESRD facility the option to make a one-time election to be excluded from the four-year transition from the current basic case-mix adjusted composite payment system in the form and manner specified by the
  
  Secretary. Once made, this election may not be rescinded. ESRD facilities may choose to be paid the blended rate under the transition period in order to give them time to determine the impact of the ESRD
  
  PPS on their operations and to adjust their operations accordingly. We believe ESRD facilities will choose to be excluded from the transition if they conclude that they would benefit financially from the payment amount under the ESRD PPS.
  
  Section 1881(b)(14)(E)(ii) of the Act requires that ESRD facilities wishing to be excluded from the transition make their election prior to
  
  January 1, 2011, in the form and manner specified by the Secretary. We are proposing that ESRD facilities notify CMS of their election choice in a manner established by their respective FI/MAC no later than
  
  November 1, 2010 regardless of any postmarks or anticipated delivery dates. A timeframe of 60 days before implementation is consistent with the timeframe that a FI/MAC is given to incorporate any updates to rates. We are also proposing that those ESRD facilities that become certified for Medicare participation and begin to provide renal dialysis services between November 1, 2010 and December 31, 2010 would notify their FI/MAC of their election choice at the time of enrollment.
  
  Once an ESRD facility notifies their respective FI/MAC of their election choice, on or before November 1, 2010 (or at the time of enrollment for newly certified ESRD facilities that begin to provide renal dialysis services between November 1, 2010 and December 31, 2010), the ESRD facility's election cannot be rescinded. We note that section 1881(b)(14)(E)(ii) of the Act provides that all ESRD facilities wishing to be excluded from the transition must make an election to be excluded from the transition. We therefore are further proposing that those ESRD facilities that fail to affirmatively make an election by
  
  November 1, 2010, would be paid based on the blended amount under the transition. Elections submitted by ESRD facilities that wish to be excluded from the transition that are received, postmarked, or delivered by other means after November 1, 2010 would not be accepted.
  
  All ESRD facilities wishing to be excluded from the transition should submit their election choice by the proposed deadline if they wish to be excluded from the transition and paid entirely based on the payment amount under the ESRD PPS for renal dialysis services furnished on or after January 1, 2011. Instruction as to how the FIs/MACs would implement the proposed ESRD PPS would be provided in future guidance.
  
  If the FIs/MACs express concern about the November 1, 2010 date, we would revisit the deadline in the ESRD PPS final rule. The proposed transition period policy is set forth in proposed Sec. 413.239.
  
  We are requesting public comment regarding our proposed blended payment rates and our proposed process for making the election to be excluded from the transition period. 1. New ESRD Facilities
  
  Although the first sentence of section 1881(b)(14)(E)(i) of the Act permits ``a provider of services or renal dialysis facility'' to make a one-time election to be excluded from the transition, the second sentence provides that this election must be made prior to January 1, 2011. Reading these two sentences together, we believe that only ESRD facilities providing renal dialysis services to Medicare beneficiaries before January 1, 2011, should have the option to choose whether to be paid under the
  
  Page 50005
  
  transition or under the ESRD PPS. We further note that the transition period provided for under section 1881(b)(14)(E)(i) of the Act is intended to provide existing ESRD facilities time to adjust from payments based on the current basic case-mix adjusted composite payment methodology to bundled payments under the ESRD PPS. New ESRD facilities that begin providing renal dialysis services and home dialysis to
  
  Medicare beneficiaries on or after January 1, 2011, would not have received payment under the current basic case-mix adjusted composite payment system; therefore, we do not believe new ESRD facilities require a transition period in order to make adjustments to their operating procedures. Accordingly, we propose that ESRD facilities that are certified for Medicare participation and begin providing renal dialysis services and home dialysis on or after January 1, 2011, not have the option to choose whether to be paid a blended rate under the transition or the payment amount under the ESRD PPS. Rather, we propose that new ESRD facilities be paid based on 100 percent of the payment amount under the ESRD PPS.
  
  As set forth in Sec. 413.171 of this proposed rule, we are proposing to define a new ESRD facility as an ESRD facility that is certified for Medicare participation on or after January 1, 2011. 2. Limitation on Beneficiary Charges Under the Proposed ESRD PPS and
  
  Beneficiary Deductible and Coinsurance Obligations
  
  Section 1833 of the Act governs payments of benefits for Part B services and the cost sharing amounts for services that are considered medical and other health services. In general, many Part B services are subject to a payment structure that requires beneficiaries to be responsible for a 20 percent coinsurance after the deductible (and
  
  Medicare pays 80 percent). With respect to dialysis services furnished by ESRD facilities to individuals with ESRD, under section 1881(b)(2)(a) of the Act, payment amounts are 80 percent (and 20 percent by the individual).
  
  In this rule, we have proposed the items and services that would be considered renal dialysis services included in the ESRD PPS payment such as the composite rate related services, certain separately billable drugs, former Part D drugs used in the treatment of ESRD, laboratory testing, etc. We understand that certain items and services such as laboratory tests and Part D drugs have different beneficiary coinsurance structures. However, these items and services would be considered renal dialysis services after the ESRD PPS is implemented when furnished by an ESRD dialysis facility to an ESRD beneficiary.
  
  Therefore, a 20 percent beneficiary coinsurance would be applicable to the ESRD PPS payment for these services including any adjustments to the ESRD PPS payment such as adjustments for case-mix, geographic wage index, outlier, etc.
  
  Thus, we are proposing that an ESRD facility receiving an ESRD PPS payment may charge the Medicare beneficiary or other person only for the applicable deductible and coinsurance amounts as specified in Sec. 413.176. The beneficiary coinsurance amount for the ESRD PPS base rate is 20 percent of the total ESRD PPS payment (including payments made under the transition). We note that the amount of coinsurance is based on the proposed ESRD PPS payment for renal dialysis services and home dialysis in 42 CFR part 413. In general, facilities are paid monthly by
  
  Medicare for the ESRD services they furnished to a beneficiary even though payment is on a per treatment basis. We are proposing to continue this practice to pay ESRD facilities monthly for services furnished to a beneficiary beginning January 1, 2011. During the transition period before January 1, 2014, ESRD facilities that do not elect to go 100 percent into the ESRD PPS in 2011 would receive a blended payment amount of the prospective payment system in effect prior to January 1, 2011, and the ESRD PPS payment amount for services furnished to a beneficiary. ESRD Facilities would receive a monthly payment that is a blended payment amount for services furnished to a beneficiary. The services included in this blended monthly payment amount would be subject to a 20 percent beneficiary coinsurance.
  
  Additionally, in accordance with section 1881(b)(1) of the Act and consistent with other established prospective payment systems policies, we are proposing in Sec. 413.172(b) that an ESRD facility may not charge a beneficiary for any service for which payment is made by
  
  Medicare. This policy would apply, even if the ESRD facility's costs of furnishing services to that beneficiary are greater than the amount the
  
  ESRD facility would be paid under the proposed ESRD PPS.
2. Claims Processing
  
  As indicated above, section 1881(b)(14)(A)(i) of the Act requires the Secretary to implement a payment system under which a single payment is made for renal dialysis services and other items and services related to home dialysis. For example, those services would include supplies and equipment used to administer dialysis in the ESRD facility or at a patient's home, drugs, biologicals, laboratory tests, and support services.
  
  Implementation of the proposed ESRD PPS will require a significant amount of changes to the way we process claims. Some of the changes could entail consolidated billing rules and edits and the data elements reported on claims, as discussed below. 1. Consolidated Billing
  
  Since the ESRD PPS payment model represents an all-inclusive payment for renal dialysis services and home dialysis items and services, the ESRD facility itself is responsible for virtually all of the services mentioned above that its patients receive. It is important that billing and payment for these services, which could be provided by other entities, such as laboratories, is made only to the ESRD facility so that duplicate payment is not made by Medicare. Therefore, as stated previously in section XIII.B, suppliers, laboratories, and Part D plans would not be permitted to bill Medicare for renal dialysis services and home dialysis items and services that they furnish to ESRD beneficiaries. The consolidated billing approach essentially confers to the ESRD facility itself the Medicare billing responsibility for all of the renal dialysis services that its patients receive. a. Laboratory Tests
  
  ESRD patients generally have many co-morbid conditions and are treated by other specialists for those conditions. As such, many of the same laboratory tests ordered by a physician to monitor a patient's
  
  ESRD, could also be ordered by other physician specialists treating the
  
  ESRD patient for other medical conditions. Therefore, it is difficult to differentiate between an ESRD related laboratory test and a test ordered for another condition. While the ideal scenario would be to require that payment for all potential ESRD related laboratory tests be made only to the ESRD facility, ESRD facilities may not be able to control the ordering of tests by physicians not treating the patient's renal disease. A consolidated billing approach could identify the source of a given laboratory test to allow separate payment when the test was not ordered in connection with the patient's ESRD condition.
  
  In order to ensure proper payment in all settings, we are exploring the use of modifiers to identify those services furnished to ESRD beneficiaries, which are excluded from the proposed ESRD PPS.
  
  Page 50006
  1. Drugs and Biologicals
  Certain drugs and biologicals routinely furnished to ESRD beneficiaries that are paid under the Medicare ESRD benefit are included in the current basic case-mix adjusted composite rate. Other
  
  ESRD-related injectable drugs are separately paid under Medicare Part
3. However, as mentioned above, section 1881(b)(14)(B) of the Act requires the inclusion of all drugs and biologicals used for the treatment of ESRD, including drugs and biologicals that were formerly covered under Medicare Part D. Therefore, we would include these drugs as part of the consolidated billing mechanism discussed above. As a result of including these former Part D ESRD drugs and biologicals in the proposed ESRD PPS, we are proposing that ESRD facilities would be required to furnish these and any other self-administered ESRD-related drugs to beneficiaries either directly or under arrangement. Such arrangements would prevent potential Medicare overpayments made under both Parts B and D. Further discussion regarding payment for former
  
  Part D drugs and biologicals can be found in section III.C. c. Home Dialysis
  
  Section 1881(b)(14)(A)(i) of the Act requires the costs of home dialysis supplies and services furnished under Method I and Method II, regardless of home treatment modality, be included in the proposed ESRD
  
  PPS. Thus, we are proposing that the Method II home dialysis approach in its present form would no longer exist under the proposed ESRD PPS effective January 1, 2011. This proposal does not eliminate Method I in its present form. Therefore, a supplier could only furnish, under arrangement with the ESRD facility, home dialysis equipment and supplies to a Medicare home dialysis beneficiary, and the supplier would have to look to the ESRD facility for payment. We believe that this approach is simpler and would reduce the administrative burden of maintaining two payment methods for home dialysis patients, as we believe that section 1881(b)(14)(A)(i) of the Act requires that all
  
  Medicare home dialysis supplies and services be paid under the proposed
  
  ESRD PPS and such payment be made to the ESRD facility. Further discussion of this proposal and information on home dialysis can be found in section III.E. 2. Expansion of the Data Elements Reported on Claims
  
  Under the current basic case-mix composite adjusted payment system,
  
  ESRD facilities are paid a composite rate for each dialysis treatment performed. Currently the composite rate includes a number of items and services beyond the dialysis treatment itself. The services that are billed on the claim do not provide any detail of the composite rate items and services that are furnished to the patient beyond the treatment itself. Examples of additional types of items and services that are included in the composite rate but are not captured on the claims and that we believe would be helpful in our ability to predict composite rate costs are: time on machine, nutritional services, social work services, and nursing services. We are not proposing additional reporting requirements at this time, but we believe that collecting additional data at patient-level is necessary for refinements to the proposed case-mix adjustments of the proposed ESRD PPS payment model.
  
  In the future, we may implement new reporting requirements where data elements, such as time on machine, nutritional services, social work services, and nursing services, would be relevant for case-mix refinements. We are requesting public comment regarding these data elements and other claim-based information that would identify patients who are high cost. Identifying other factors that explain costs could assist us in developing future patient-level adjusters that would further refine the model that we used to develop the proposed ESRD PPS.
  
  Detailed instruction as to how claims would be processed under the proposed ESRD PPS will be provided in future guidance.
4. Operational Issues Surrounding Payment for Self Administered ESRD-
  
  Related Drugs and Biologicals
  
  As we discussed in section III. of this proposed rule, section 1881(b)(14)(B)of the Act defines renal dialysis services to include, among other things, certain drugs and biologicals, including drugs and biologicals that were separately payable under Parts B and D. Under the current ESRD basic case-mix adjusted composite payment system, ESRD facilities generally do not furnish oral drugs and biologicals to their
  
  ESRD patients. ESRD patients currently acquire these drugs and biologicals either through Medicare Part D, private insurance, or independently.
  
  As described in section III. of this proposed rule, we are proposing to include renal dialysis service drugs formerly covered under Part D under the proposed ESRD PPS. As a result, we are further proposing that ESRD facilities would be required to furnish these and any other self-administered ESRD-related drugs to beneficiaries either directly or under arrangement. Regardless of the mechanism by which these drugs would be furnished (directly or under arrangement), as ESRD facilities assume responsibility for the provision of these drugs that were formerly furnished by the Part D plans, we believe that some of the Part D provisions set forth in the 42 CFR Part 423, would become relevant for ESRD facilities. We are particularly interested in assuring beneficiary access to these drugs. As such, we request public comment on the extent to which Part D access requirements including, but not limited to, pharmacy networks and formularies may be relevant in the context of ESRD facilities' provision of renal dialysis service drugs.
  
  In addition, consistent with the patients' rights processes set forth in Sec. 494.70(a) and the condition: governance processes set forth in Sec. 494.180(e) of the conditions for coverage for ESRD facilities, we would expect that the ESRD facilities would update their grievance processes to account for all self-administered ESRD-related drugs. Patients would continue to have access to both internal and external grievance processes including the ESRD Network and the State survey agency.
  
  In the case of any ESRD facility that would seek to furnish drugs directly by dispensing on-site, we would expect that such facility comply with state pharmacy licensure requirements. As an alternative, we believe that many ESRD facilities would forego the process of becoming licensed as a pharmacy and instead, furnish renal dialysis service drugs formerly covered under Part D under arrangement with a licensed pharmacy. Under this scenario, the patient's MCP physician would prescribe the drugs or biologicals. The patient would obtain these drugs from a retail or mail order pharmacy with which the ESRD facility has contracted. We would expect that the ESRD facility would provide their patients with a listing of pharmacies with which it would have arrangements with to dispense the renal dialysis service drugs.
  
  As indicated in proposed Sec. 413.241 of this proposed rule, we would further expect that the ESRD facilities would establish arrangements with pharmacies in a manner that would facilitate beneficiary access to renal dialysis service drugs. That is to say, at a minimum, we would expect that the arrangement would take into account variables like the terrain, whether the patient's home is located in an urban or
  
  Page 50007
  
  rural area, the availability of transportation, the usual distances traveled by patients in the area to obtain health care services, and the pharmacy's capability to provide all classes of renal dialysis service drugs to patients in a timely manner.
  
  In addition, we would expect that ESRD facilities would coordinate the provision of renal dialysis service drugs on behalf of traveling patients to facilitate ongoing compliance with the plan of care during periods of travel.
  
  To prevent duplicate payment under both Part D and Part B for bundled drugs and biologicals formerly covered under Part D, we are considering the incorporation of an ESRD indicator on the Part D eligibility information that would prevent Part D drug payments for bundled ESRD drugs and biologicals at the pharmacy. For example, similar to the Part D requirements in Sec. 423.120(c), ESRD facilities could issue a card or other type of technology that its enrollees may use to access renal dialysis service drugs through pharmacies with which they have established arrangements.
  
  The pharmacy would bill the ESRD facility for all renal dialysis service drugs and biologicals included in the proposed ESRD PPS that were dispensed, but would not be permitted to bill the patient for the usual Part B coinsurance amount, nor treat these drugs in accordance with the Part D rules. As discussed in section XIII.A.2. of this proposed rule, the ESRD facility would collect applicable beneficiary coinsurance that is based on the proposed ESRD PPS per treatment payment amount.
  
  As discussed in section VII. of this proposed rule, the cost of the drugs and biologicals currently separately payable under Part D that we propose to be designated as Part B renal dialysis services for purposes of the proposed ESRD PPS, would be reflected in the ESRD PPS portion of the blended payment. In addition, the mechanism by which we propose to address payment for these drugs during the transition as an adjustment to the blended payment related to basic case-mix adjusted composite payment system is discussed in section VII.D.b. of this proposed rule.
Evaluation of Existing ESRD Policies and Other Issues

We reviewed existing ESRD policies to determine their applicability to the proposed ESRD PPS. We propose to eliminate the exceptions for isolated essential facilities, self dialysis training costs, atypical service intensity (patient mix) and pediatric facilities that exist under the case-mix adjusted composite payment system. We would maintain the current erythropoeisis stimulating agent monitoring policy, bad debt policy, reporting requirements for circumstances whereby Medicare is the secondary payer (MSP), and the 50-cent deduction to fund the

ESRD Networks. We also propose to set forth in Sec. 413.195 the limitation on review with regard to the ESRD PPS. In addition, we are considering the extent to which the laboratory services 50 percent rule would continue to apply under the proposed ESRD PPS.
1. Exceptions Under the Case-Mix Adjusted Composite Payment System
  
  Section 1881(b)(7) of the Act and Sec. 413.182 generally address exceptions to the composite payment rates. Section 422(a)(2) of BIPA prohibited the granting of new exceptions to the composite payment rates after December 31, 2000, but did allow the continuation of the existing exceptions as long as the exception rate exceeded the applicable composite payment rate. Section 623(b) of the MMA amended section 422(a)(2) of BIPA to restore composite rate exceptions for pediatric facilities that did not have an exception rate in effect as of October 1, 2002. Section 422(a)(2)(D) of BIPA defined a pediatric facility as a renal dialysis facility at least 50 percent of whose patients are under 18 years of age.
  
  In the calendar year (CY) 2005 Physician Fee Schedule (PFS) proposed rule (69 FR 47535), we explained that section 422(a)(2)(C) of
  
  BIPA provided that any ESRD composite rate exception in effect on
  
  December 31, 2000, would continue as long as the exception rate exceeds the applicable composite payment rate. We further explained that when computing an exception amount, the facility's patient population and the higher costs relating to case-mix are taken into consideration. We indicated that we were proposing to allow each dialysis facility the option of continuing to be paid at its exception rate or at the basic case-mix adjusted composite rate. On April 1, 2004, we opened the exception window for pediatric facilities and noted that the window would close in September 27, 2004. In the CY 2005 PFS final rule with comment period (69 FR 66332), we stated that the exception process was opened each time there is a legislative change in the composite payment rate or when we open the exception window. We indicated our intent to open the pediatric exception windows on an annual basis. We also noted that we would provide for the continuation of the home training exception to allow for facilities with home training exceptions to retain their current training exception rates as well as take advantage of the case-mix adjusted rates for non-training dialysis.
  
  While section 153 of the MIPPA does not directly address exceptions, we believe that the ESRD PPS under section 1881(b)(14) of the Act, creates an ESRD bundled prospective payment in lieu of payment under previous ESRD payment systems and given that the ESRD PPS no longer directly addresses changes in the ESRD composite rate, we believe that the exceptions currently in place would no longer apply.
  
  We also believe that we have addressed the higher costs relating to case-mix through the patient characteristic adjustments and outlier payments that are discussed in detail in sections VIII.B and X.A.
  
  Therefore, we are proposing the elimination of the isolated essential facility, self dialysis training costs, atypical service intensity
  
  (patient mix) and pediatric facility exceptions effective for ESRD renal dialysis services furnished on or after January 1, 2014 (at the conclusion of the phase-in). In other words, any existing exceptions would terminate effective for ESRD treatment on or after January 1, 2014. Additionally, no further exception windows would be open effective for ESRD treatment furnished on or after January 1, 2011, the effective date of the ESRD PPS. In the event that an ESRD facility elects to receive full payment under the ESRD PPS for renal dialysis services furnished on or after January 1, 2011, any existing exceptions would no longer be recognized. In the event that an ESRD facility elects to receive payment under the transition period, any existing exceptions would be recognized for purpose of the basic case-mix adjusted composite payment system portion of the blended payment through the transition. We propose to include the periods of exceptions and the elimination of the exceptions to the composite payment rates in
  
  Sec. 413.180 of the regulations. With respect to appeals under Sec. 413.194(b) we point out that such appeals apply only to exceptions to the composite rate granted before January 1, 2011.
2. Erythropoiesis Stimulating Agent (ESA) Monitoring Policy
  
  In 2003, we solicited input from the ESRD community, in order to develop an erythropoiesis stimulating agent (ES
3. Monitoring Policy.
  
  After input from the community, we implemented, through administrative issuance, the first iteration of the monitoring policy effective for services provided on or after April 1, 2006. On July 20, 2007, we issued through administrative issuance, a revised policy effective for services
  
  Page 50008
  
  furnished on or after January 1, 2008. We are currently evaluating the extent to which we could continue the ESA Monitoring Policy for renal dialysis services furnished on or after January 1, 2011. Specifically, at the current time it is not known how the reduction in payment that is currently applied to the separately billed ESAs would be applied under the proposed ESRD PPS. As discussed in section X.A, we are also continuing to evaluate how to establish eligibility for outlier payments in instances where the ESA Monitoring Policy is implicated. We request public comments on this issue to inform our evaluation.
4. ESRD Facility Network Deduction
  
  Pursuant to section 1881(b)(7) of the Act, to fund the ESRD
  
  Networks, 50 cents is deducted from the amount of each payment for each treatment (subject to such adjustments as may be required to reflect modes of dialysis other than hemodialysis). The reduction amount applies to all treatment modalities. The methodology for calculating the reduction is described in the Medicare Claims Processing Manual,
  
  Pub. 100-04, Ch. 8, section 110. We would continue this deduction with the ESRD PPS effective for services provided on or after January 1, 2011, with a 50 cent reduction per treatment from the payment made to
  
  ESRD facilities under the ESRD PPS for facilities that elect to receive payment under the ESRD PPS (subject to such adjustments as may be required to reflect modes of dialysis other than hemodialysis). For facilities that elect to receive ESRD payment during the transition, we would apply the reduction methodology as described above to the blended payment amount during the transition.
5. Bad Debt
  
  Section 413.89 of the regulations and Chapter 3 of the Provider
  
  Reimbursement Manual, Part 1 (PRM) (CMS Pub. 15-1) set forth the general requirements and policies for payment of bad debts attributable to unpaid Medicare deductibles and coinsurance amounts. Additional requirements for ESRD facilities are set forth at Sec. 413.178.
  
  Under the basic case-mix adjusted payment system, Medicare pays
  
  ESRD facilities 80 percent of a prospectively set composite rate for outpatient dialysis services. The Medicare beneficiary is responsible for the remaining 20 percent as coinsurance, as well as any applicable deductible amounts as set forth in Sec. 413.176 of the regulations. If the ESRD facility makes reasonable collection efforts, as described in the Section 310 of the PRM, but is unable to collect the deductible or coinsurance amounts for items or services associated with the composite rate, we consider the uncollected amount to be a ``bad debt'' if the facility meets the requirements at Sec. 413.178 and Sec. 413.89 of the regulations and Chapter 3 of this proposed rule.
  
  At the end of the ESRD facility cost reporting period, Medicare recognizes a facility's Medicare bad debts. However, Sec. 413.178(a) requires CMS to reimburse ESRD facilities for its allowable bad debt up to the facility's costs as determined under Medicare principles.
  
  In developing the proposed changes to the ESRD payment system described in this proposed rule, section 153(a)(4) of MIPPA states, as a Rule of Construction, that, ``nothing in this subsection or the amendments made by this subsection shall be construed as authorizing or requiring the Secretary of Health and Human Services to make payments under the payment system implemented under paragraph (14)(A)(i) of section 1881(b) of the Social Security Act (42 U.S.C. 1395rr(b)), as added by paragraph (1), for any unrecovered amount for any bad debt attributable to deductible and coinsurance on items and services not included in the basic case-mix adjusted composite rate under paragraph
  
  (12) of such section as in effect before the date of the enactment of this Act.''
  
  Therefore, under the proposed ESRD PPS, bad debt payments will continue to be made for the unpaid Medicare deductibles and coinsurance amounts for only those items and services associated with the basic case-mix adjusted composite rate. However, since the proposed single
  
  ESRD payment rate is for items and services included in the composite rate and for drugs and laboratory tests, we are proposing to use only the composite rate portion of the proposed single ESRD payment rate to determine bad debt payments. We are proposing that bad debt payments for ESRD facilities would continue to be capped as required under Sec. 413.178(a). The Medicare cost report and instructions in the PRM, Part 2 (CMS Pub. 15-2) may be revised to report the case mix adjusted composite rate payment and associated cost data necessary to compute the ESRD facility bad debt payments.
  
  In addition, we are proposing to make a conforming change to regulation text at Sec. 413.178(d) regarding ESRD bad debt payment made under the proposed ESRD payment system described in this proposed rule. We are also including a cross-reference to Sec. 413.178 in Sec. 413.89(h) and (i).
6. Limitation on Review
  
  In addition to requiring the establishment of the ESRD PPS, section 153(b) of MIPPA amends section 1881(b) of the Act to provide for a limitation on review. Specifically, section 1881(b)(14)(G) of the Act provides the following: ``There shall be no administrative or judicial review under section 1869 of the Act, section 1878 of the Act or otherwise of the determination of payment amounts under [section 1881(b)(14)(A)], the establishment of an appropriate unit of payment under [section 1881(b)(14)(C)], the identification of of renal dialysis services included in the bundled payment, the adjustments under
  
  section 1881(B)(14)(D)
  
  , the application of the phase-in under
  
  section 1881(b)(14)(E)
  
  , and the establishment of the market basket percentage increase factors under [section 1881(b)(14)(F)].'' We propose to codify this limitation on review in Sec. 413.195 of the regulations.
7. 50 Percent Rule Utilized in Laboratory Payments
  
  As specified in CMS Pub 100-04, Chapter 16, Sect. 40.6, for a particular date of service to a beneficiary, if 50 percent or more of the covered laboratory tests within an Automated Multi-Channel
  
  Chemistry (AMCC) test are included under the composite rate payment, then all submitted tests are included within the composite payment and no separate payment in addition to the composite rate is made for any of the separately billable tests. If less than 50 percent of the covered laboratory tests within the AMCC are composite rate tests, then all AMCC tests submitted are separately payable. When ordering ESRD- related AMCC tests, ESRD facilities identify, for a particular date of service, each test that is included in the composite rate and each test that is not included. A ``non-composite rate test'' is defined as ``any test separately payable outside the composite rate or beyond the normal frequency covered under the composite rate that is reasonable and necessary.''
  
  During the transition period, the 50 percent rule would continue to apply to the basic case mix adjusted composite payment system portion of the blended payment. Under the proposed consolidated billing provisions discussed further in section XIII B. of this proposed rule, the ESRD facility itself would assume the Medicare billing responsibility for all of the renal dialysis services that its patients receive, including laboratory tests. As a result, the ESRD facilities would apply the 50 percent rule billing procedures
  
  Page 50009
  
  including application of the relevant modifiers.
  
  As described in section X of this proposed rule, under the proposed
  
  ESRD PPS, Medicare would not make separate payment for laboratory tests, rendering the 50 percent rule irrelevant for payment purposes.
  
  The 50 percent rule's relevance would be limited to its use in determining eligibility for outlier payment.
  
  In addition, preliminary analyses reveal a small impact upon removing from eligibility for outlier services the AMCC tests to which the 50 percent rule applies. As a result, we are considering excluding
  
  AAMC tests to which the 50 percent rule applies from the definition of outlier services, thus negating the need to apply the 50 percent rule under the proposed ESRD PPS. We plan to continue to evaluate the impact of this approach and include further discussion in the final rule. We request public comments on whether or not to include the AMCC tests to which the 50 percent rule applies within the definition of outlier services and retain the 50 percent rule under the proposed ESRD PPS.
8. Medicare as a Secondary Payer
  
  Medicare may be a secondary payer (MSP) when the primary payer is a group health plan for ESRD items and services furnished to Medicare beneficiaries during the 30-month Medicare coordination of benefit period. At this time, we are unable to identify the systems operations and billing procedures impact of this relationship under the current basic case-mix adjusted composite payment system, and we are exploring how it will be utilized and managed under the proposed ESRD prospective payment system. We believe that while there may need to be system changes in order to process MSP claims under the Proposed ESRD prospective payment system, there should be no impact on ESRD providers and on primary payers. We will issue through administrative issuance, any changes in the manner of reporting information, should that be required. We are soliciting public comment on the operational issues of
  
  MSP under the proposed ESRD payment system.
Quality Incentives in the End-Stage Renal Disease (ESRD) Program
1. Introduction
  
  Section 1881(h) of the Social Security Act (the Act), as added by section 153(c) of the Medicare Improvements for Patients and Providers
  
  Act of 2008 (MIPPA), requires the Secretary to develop a quality incentive program (QIP) that will result in payment reductions to providers of services and dialysis facilities that do not meet or exceed a total performance score with respect to performance standards established with respect to certain specified measures. As provided under section 1881(h) of the Act, the payment reductions, which will be up to 2.0 percent of the payments otherwise made to providers and facilities under section 1881(b)(14), will apply to renal dialysis services furnished on or after January 1, 2012, and the total performance score that providers and facilities must meet or exceed in order to receive their full payment will be based on a specific performance period prior to this date. The payment reductions will apply with respect to the year involved and will not be taken into account when computing future payment rates.
  
  The CMS is committed to developing and implementing an ESRD QIP, and we intend to issue a subsequent proposed rule that makes detailed proposals regarding how we plan to implement section 1881(h) of the
  
  Act. However, in the interim, with one exception described below, we believe it is important to describe the QIP conceptual model that CMS is considering proposing for purposes of the payment reduction that will apply with respect to renal dialysis services furnished on or after January 1, 2012. Therefore, we will present the model below so that the public has an opportunity to comment on it, and we will use the comments to inform our evaluative, analytic, and guidance efforts during the development of the QIP.
  
  The one exception mentioned above is the measure set that will apply for purposes of the CY 2012 payment reduction. We are making specific proposals with respect to that measure set in this proposed rule so that the public will be informed as early as possible regarding the measures on which the performance standards will be based.
2. Background
  
  Quality monitoring and provider accountability is important in the
  
  ESRD payment system and has been done for over 30 years. We will describe the evolution of our ESRD quality monitoring initiatives by category below: 1. ESRD Network Organization Program
  
  In the End-Stage Renal Disease Amendments of 1978 (Pub. L. 95-292),
  
  Congress required the formation of ESRD Network Organizations to further support the ESRD program. CMS currently contracts with 18 ESRD
  
  Networks throughout the United States to perform oversight activities and to ensure that dialysis patients are provided appropriate care. The
  
  Networks' responsibilities include monitoring the quality and improvement of care received, providing technical assistance to patients who have ESRD and providers/facilities that treat ESRD patients, and addressing patient grievances. In 1994, CMS and the
  
  Networks, with input from the renal community, established the ESRD
  
  Core Indicators Project (CIP). The ESRD CIP was CMS's first nationwide population-based study designed to assess and identify opportunities to improve the care of patients with ESRD. This project established the first consistent clinical ESRD database. Information included in the database included clinical measures thought to be indicative of key components of care surrounding dialysis. 2. Clinical Performance Measures (CPMs)
  
  Section 4558(b) of the Balanced Budget Act of 1997 required CMS to develop and implement, by January 1, 2000, a method to measure and report the quality of renal dialysis services furnished under the
  
  Medicare program. To implement this legislation, CMS developed the ESRD
  
  Clinical Performance Measures (CPM) Project, based on the National
  
  Kidney Foundation's Dialysis Outcome Quality Initiative (NKF-DOQI)
  
  Clinical Practice Guidelines. The purpose of the ESRD CPM Project is to provide comparative data to ESRD facilities to assist them in assessing and improving the care furnished to ESRD patients. Sixteen CPMs were developed in 1998 to measure and report the quality of dialysis services furnished under Medicare in the areas of hemodialysis and peritoneal dialysis adequacy, anemia management, and vascular access management. The first data collection effort for the ESRD CPMs began in 1999. These CPMs are calculated using information contained in patients' records. CPMs are collected on a national random sample of adult in-center hemodialysis patients, all in-center hemodialysis patients less than 18 years of age, and a national random sample of peritoneal dialysis patients. Data are collected annually and submitted to CMS via a predominantly paper-based process. The CPMs are calculated and released in the Department of Health and Human Services' Annual
  
  Report on the ESRD CPM Project.

  3. Dialysis Facility Compare (DFC)
  
  Also in response to the Balanced Budget Act of 1997, we created
  
  Dialysis Facility Compare (DFC) as a new feature on http:// www.medicare.gov that was modeled after Nursing Home Compare. We worked with a contractor and a consumer workgroup to identify dialysis facility-specific measures that could be provided to the public for consumer choice and information purposes. This tool was launched in
  
  January 2001 on the http://www.medicare.gov Web site to provide information to the public for comparing the quality of dialysis facilities and providers across the country, including specific information about services and the quality of care furnished by a specific dialysis facility/provider. DFC captures administrative and quality related data submitted by dialysis facilities and providers.
  
  The key quality measures captured in this tool include facility- level measures of anemia control, adequacy of hemodialysis treatment and patient survival. Medicare claims data are used to calculate the anemia management and dialysis adequacy rates and administrative data
  
  (non-clinically based data such as demographic data, and data acquired from the Social Security Administration and obtained from the CMS forms 2728 and 2746) used to determine the patient survival rates. The anemia measure shows the raw number or the percentage of patients at a given facility/provider whose anemia (low red blood cell count) was not controlled. More specifically, the anemia measure is the percentage of patients whose hematocrit levels are at 33 percent (33 percent out of 100 percent) or more (or hemoglobin levels of 11 g/dL or more). The dialysis adequacy measure shows the raw number or the percentage of in- center hemodialysis patients at a facility that get effective treatments during dialysis. More specifically, the measure is the percentage of patients with urea reduction ratio (URR) levels of 65 percent or more. The patient survival measure shows whether patients treated at a certain facility generally live longer, as long, or not as long as expected. These measures are updated annually on the DFC Web site, usually at the end of the year, using data from the previous year for the dialysis adequacy and anemia measures and data from the past four years for the patient survival measure.
  
  In November 2008, the anemia management measure was updated using facility and claims data from 2007. Recent evidence about increased risk of certain adverse events associated with the use of erythropoiesis-stimulating agents (ESAs), which are used to treat anemia, raised concerns about patients who have hemoglobin levels too high, as well as patients whose hemoglobin levels are too low. The Food and Drug Administration (FDA) responded by requiring manufacturers to develop a Medication Guide (http://www.fda.gov/cder/drug/advisory/
  
  RHE200711.htm) and to ensure that this information is provided to patients. The labeling guideline states ``The dosing recommendations for anemic patients with chronic renal failure have been revised to recommend maintaining hemoglobin levels within 10 g/dL to 12 g/dL''
  
  (http://www.fda.gov/cder/drug/advisory/RHE200711.htm). As a result of this guideline, DFC was revised to include two anemia measures: one measure shows the percentage of patients whose hemoglobin levels are considered too low (that is, below 10 g/dL), and a second measure shows the percentage of patients whose hemoglobin levels are too high (that is, above 12 g/dL). In addition, CMS has updated the way it reports patient survival rates on DFC to reflect whether patients treated at a provider/facility generally live longer than, as long, or not as long as expected. 4. ESRD Quality Initiative
  
  In 2004, the ESRD Quality Initiative was launched. The objective was to stimulate and support significant improvements in the quality of dialysis care. The initiative aimed to refine and standardize dialysis care measures, ESRD data definitions, and data transmission to support the needs of the ESRD program; empower patients and consumers by providing access to facility service and quality information; provide quality improvement support to dialysis providers; assure compliance with conditions of coverage; and build strategic partnerships with patients, providers, professionals, and other stakeholders. Components of this Quality Initiative included the DFC, the CPM Project, and the
  
  Fistula First Breakthrough Initiative. 5. ESRD Conditions for Coverage
  
  The ESRD Conditions for Coverage final rule published on April 15, 2008, and contains revised requirements that dialysis providers and facilities must meet in order to be certified under the Medicare program. As part of the revised requirements, dialysis providers and facilities are required to implement a quality assessment and performance improvement program. In addition, providers and facilities are required to submit the CPMs electronically on all their patients on an annual basis. The CPMs were updated and expanded in April 2008 through a National Quality Forum (NQF) endorsement process. The current
  
  CPMs include 26 measures in the areas of anemia management; hemodialysis adequacy; peritoneal dialysis adequacy; mineral metabolism; vascular access; patient education/perception of care/ quality of life; and patient survival. The anemia management measures for patients receiving erythropoiesis-stimulating agents (ESAs) and the urea reduction ratio (URR) measure (in-center hemodialysis) are not NQF endorsed. 6. CROWNWeb
  
  CMS has developed a new Web-based system, Consolidated Renal
  
  Operations in a Web-Enabled Network (CROWNWeb) for the purposes of collecting CPM data electronically from dialysis facilities. Use of the
  
  CROWNWeb system will increase the efficiency of data collection for both CMS and providers/facilities, improve data quality, and provide a more stable and accessible platform for continual improvements in functionality. In February 2009, CMS began implementing the CROWNWeb system with a number of providers/facilities and plans to expand reporting to additional providers/facilities as soon as practicable.
3. The ESRD Quality Incentive Program as Authorized by Section 1881(h) of the Act
  
  Recognizing the need for additional quality monitoring in an ESRD payment system, Congress required in section 153 of MIPPA that the
  
  Secretary implement an ESRD quality incentive program (QIP). We believe that the QIP is the next step in the evolution of the ESRD quality program because it measures provider/facility performance versus being focused on reporting outcome data.
  
  Specifically, section 1881(h) of the Act, as added by section 153(c) of MIPPA, requires the Secretary to develop a QIP that will result in payment reductions to providers of services and dialysis facilities that do not meet or exceed a total performance score with respect to performance standards established with respect to certain specified measures. As provided under this section, the payment reductions, which will be up to 2.0 percent of payments otherwise made to providers and facilities under section 1881(b)(14), will apply to renal dialysis services furnished on or after January 1, 2012, and the total performance score that providers and facilities must meet
  
  Page 50011
  
  or exceed in order to receive their full payment will be based on a specific performance period prior to this date. Under section 1881(h)(1)(C), the payment reduction will only apply with respect to the year involved and will not be taken into account when computing future payment rates.
  
  For the ESRD quality incentive program, section 1881(h) of the Act generally requires the Secretary to: (1) Select measures; (2) establish the performance standards that apply to the individual measures; (3) specify a performance period with respect to a year; (4) develop a methodology for assessing the total performance of each provider and facility based on the performance standards with respect to the measures for a performance period; and (5) apply an appropriate payment reduction to providers and facilities that do not meet or exceed the established total performance score.
  
  We view the ESRD QIP required by section 1881(h) of the Act as the next step in the evolution of the ESRD quality program that began more than 30 years ago. Our vision is to develop a robust, comprehensive
  
  ESRD QIP that builds on the foundation that has already been established. As we move towards this larger goal, we understand the importance of giving providers and facilities time to prepare for the implementation of this new quality incentive program and to assess how the new program will affect them.
  
  Therefore, we are outlining below a conceptual model that describes various components of an ESRD QIP that we are considering proposing in a future proposed rule. We want to make clear that this is only a model, with one exception. The exception, more fully described below, is that we are proposing to initially adopt for the QIP three measures, two of which assess anemia management and one which assesses hemodialysis adequacy, which can be calculated using Medicare claims data.
  
  Our goal is to propose to implement other components of the QIP in future rulemaking. Our purpose in describing a model in this proposed rule is to notify the public regarding what we believe at this time to be essential components of the QIP in the hope of receiving detailed comments on those components. We also note that the model described below represents our thinking on what we are considering implementing only for payment consequence year 2012 because we anticipate that the program will evolve as we conduct additional analyses, gather experience, and respond to industry feedback. 1. Proposed Anemia Management and Dialysis Adequacy Measures
  
  Section 1881(h)(2)(A)(i) of the Act requires that the measures specified for the QIP include measures on anemia management that reflect the labeling approved by the Food and Drug Administration for such management, and measures on dialysis adequacy. To implement this section, we are proposing that for the first QIP performance period, we will adopt the two anemia management measures and one hemodialysis adequacy measure that are currently used for DFC. Data needed to calculate these measures can be collected from Medicare claims submitted by ESRD providers and facilities on a patient-specific basis.
  
  The anemia management measures used for DFC assess the percentage of patients at a facility whose anemia was not controlled at both the high and low ends of the FDA recommended hemoglobin levels.
  
  Specifically, these measures are: (1) The percentage of patients at a provider/facility whose hemoglobin levels were less than 10 g/dL, and
  
  (2) the percentage of patients at a provider/facility whose hemoglobin levels were greater than 12 g/dL.
  
  Section 1881(h)(2)(A)(i) of the Act provides that the anemia management measures must reflect the labeling approved by the FDA for such management. The current FDA labeling guideline released November 8, 2007 for the administration of erythropoesis-stimulating agents
  
  (ESAs) to patients with chronic kidney disease, including ESRD patients, states ``The dosing recommendations for anemic patients with chronic renal failure have been revised to recommend maintaining hemoglobin levels within 10 g/dL to 12 g/dL.''
  
  We believe that the proposed anemia management measures reflect the approved FDA labeling for anemia management because they assess the number of patients whose hemoglobin levels are at the low and high end of the FDA label recommendation. In addition, we believe that it is more appropriate to adopt two measures which together assess the high and low ends of the FDA recommended hemoglobin level range, rather than a single measure that reflects the percentage of patients who have hemoglobin levels within the 10 through 12 g/dL range, because two measures will provide a richer picture of provider/facility performance. These data will also allow us to calculate the percentage of patients who have hemoglobin levels within the 10 through 12 range g/dL. Therefore, we propose to adopt these two anemia management measures for the QIP.
  
  Anemia data has been reported on Dialysis Facility Compare (DFC) since January 2001. As we noted above, we updated the reporting of anemia data for DFC in November of 2008 to be consistent with the new
  
  FDA labeling guideline released in November 2007; however, the methodology for calculating the provider/facility, state, and national averages for anemia measures has not changed since the initial release of DFC. We are proposing to use the same methodology we use to calculate the anemia management measures for purposes of DFC to calculate them for purposes of the QIP because the methodology is consistent with how we have calculated that data since 2001. Under this methodology, we will calculate the measures using hemoglobin data for
  
  Medicare patients who have been diagnosed with ESRD for at least 90 days and whose Medicare claims submitted by providers/facilities indicated the use of an ESA during that 90-day period. Data from patients whose first ESRD maintenance dialysis starts before day 90 or who have hemoglobin values of less than 5 or greater than 20 will be excluded from the measure calculation. In addition, there must be for the same patient at least 4 claims meeting this criteria for that data to be included in the data for a specific provider or facility.
  
  Technical details on the methodology we are proposing to use to calculate the anemia measures are available on the University of
  
  Michigan Kidney Epidemiology and Cost Center Web site at http:// www.sph.umich.edu/kecc/assets/documents/facguide.pdf.
  
  The hemodialysis adequacy measure (urea reduction ratio [URR]) that we are proposing to adopt is also used for DFC and assesses the percentage of patients at a provider or facility that get their blood cleaned adequately (blood urea is removed during their in-center hemodialysis). Specifically, this measure assesses the percentage of hemodialysis patients at a provider or facility whose urea reduction ratio (URR) is 65 percent or greater, a standard based on the National
  
  Kidney Foundation's Kidney Disease Quality Initiative Clinical Practice
  
  Guidelines (NKF-KDOQI). These guidelines are widely used and generally accepted throughout the ESRD community. More information on the calculation of the URR is available on the DFC Web site at http:// www.medicare.gov. This measure has been endorsed by the National
  
  Quality Forum (NQF), an organization that endorses quality measures through a public consensus process, although we note that NQF
  
  Page 50012
  
  endorsement of dialysis adequacy measures is not a requirement under section 1881(h)(2)(A)(i).
  
  The methodology for calculating the provider/facility, state, and national averages for the in-center hemodialysis measure has been used since January 2001 with the initial release of DFC, and we are proposing to use the same methodology to calculate the measure for purposes of the QIP to be consistent with how that data has been calculated since 2001. Under this methodology, we will calculate URR data only for Medicare patients who have been diagnosed with ESRD and received maintenance dialysis for at least 183 days from the date that they received their first maintenance dialysis treatment, and whose
  
  Medicare claims submitted by providers/facilities included a value for the URR. In addition, there must be for the same patient at least 4 claims meeting the criteria above for that data to be included in the data for a specific provider or facility. Technical details about the methodology we are proposing to use to calculate the hemodialysis adequacy measure are available on the University of Michigan Kidney
  
  Epidemiology and Cost Center Website at http://www.sph.umich.edu/kecc/ assets/documents/facguide.pdf.
  
  We note that the data we need to calculate the proposed anemia management and hemodialysis adequacy measures described above can be collected through ESRD claims, which is the only complete provider and facility level data set available to CMS at this time. For this reason, we are proposing to adopt only the two anemia management measures and one dialysis adequacy measure described above. Although we recognize that section 1881(h)(2)(A)(i) states that the measures shall include
  
  ``measures on anemia management that reflect the labeling approved by the Food and Drug Administration for such management and measures on dialysis adequacy,'' only one dialysis adequacy measure is collected nationally and available to determine provider and facility-specific values. For this reason, we are proposing at this time to adopt only one dialysis adequacy measure. We also note that section 1881(h)(2)(A)(iii) states that the measures shall include, to the extent feasible, other measures as the Secretary specifies including measures on iron management, bone mineral metabolism, and vascular access (including for maximizing the placement of arterial venous fistula). CMS is not proposing to adopt any measures in these categories at this time since we are not currently collecting data that would allow determination of provider and facility-specific performance with respect to these categories of measures. We are working to identify appropriate sources from which we can adequately capture data to support the future adoption of additional measures. Finally, it is not feasible to propose a patient satisfaction measure at this time because there is no validated data collection tool available to collect relevant and industry accepted patient satisfaction measure data.
  
  Therefore, it is not feasible to propose more than the aforementioned measures at this time because of the lack of complete and accurate data. Subsequent rulemaking will address other measures. 2. Performance Standards for the ESRD QIP Measures
  
  Section 1881(h)(4)(A) of the Act requires the Secretary to establish performance standards with respect to the measures selected for the QIP for a performance period with respect to a year. Section 1881(h)(4)(B) provides that the performance standards shall include levels of achievement and improvement, as determined appropriate by the
  
  Secretary. However, in our model, for the first performance period, we would establish a performance standard for the proposed anemia management and hemodialysis adequacy measures based on the special rule in Section 1881(h)(4)(E). This provision requires the Secretary to
  
  ``initially'' use as a performance standard for the anemia management and dialysis adequacy measures the lesser of a facility-specific performance rate in the year selected by the Secretary under the second sentence of section 1881(b)(14)(A)(ii), or a standard based on the national performance rate for such measures in a period determined by the Secretary. We would not include in this performance standard levels of achievement or improvement because we do not believe that section 1881(h)(4)(E) requires that we include such levels. In addition, we would interpret the term ``initially'' to apply only to the performance period applicable for payment consequence year 2012. For subsequent performance periods, we plan to propose performance standards under section 1881(h)(4)(A). Such standards will include levels of achievement and improvement, as required under section 1881(h)(4)(B).
  
  As stated above, to implement the special rule for the proposed anemia management and hemodialysis adequacy measures, we would need to compare the performance of a provider or facility on these measures during the year selected by the Secretary for purposes of calculating the ESRD bundle with the performance of the provider or facility using a performance standard based on the national performance rates for these measures in a period determined by the Secretary. For purposes of making this comparison in our model, the provider/facility-level performance year referenced in section 1881(h)(4)(E)(i) would be 2007, 2008, or 2009, depending on which of those years is selected by the
  
  Secretary for purposes of calculating the ESRD bundle. We would refer to this year as the ``base utilization year.'' The provider/facility- specific rates for 2007 are currently posted on the DFC Web site.
  
  In terms of establishing a performance standard based on national performance rates as required under section 1881(h)(4)(E)(ii), we are considering adopting a standard that is equal to the average performance of all dialysis providers and facilities based on 2008 data. These data for the anemia management and hemodialysis adequacy measures will be posted on DFC in November 2009.
  
  Although the 2008 data are not yet available on DFC, the national averages currently posted on the DFC website for 2007 are
  
  For the proposed anemia management measure (Anemia
  
  Management Measure less than 10)--the percentage of Medicare patients who have an average hemoglobin value less than 10.0 g/dL in a provider/ facility: 2 Percent
  
  For the proposed anemia management measure (Anemia
  
  Management Measure more than 12)--the percentage of Medicare patients who have an average hemoglobin value greater than 12.0 g/dL in a provider/facility: 44 Percent
  
  For the proposed hemodialysis adequacy measure
  
  (Hemodialysis Adequacy One)--the percentage of Medicare patients in a provider/facility with URR levels above 65 percent: 95 Percent.
  
  We expect that these averages will change for 2008.
  
  This means that, for purposes of implementing the special rule in our model for the proposed anemia management and hemodialysis adequacy measures, the performance standard for the initial performance period would be the lesser of (1) the provider/facility-specific rate for the base utilization year, or (2) the national average results from 2008 claims data. If a provider or facility performed below the national average, then we would
  
  Page 50013
  
  look at the provider/facility-specific rate for the base utilization year to determine whether the provider/facility's performance during the initial performance period meets or exceeds the performance standard.
  
  We note that the proposed hemodialysis adequacy measure would assess hemoglobin values only in hemodialysis patients who receive treatment at a provider or facility (and not in hemodialysis or peritoneal dialysis patients treated at home). In addition, the proposed hemodialysis adequacy measure would not assess hemoglobin values in pediatric dialysis patients. Therefore, we are seeking public input about this issue and ideas about whether and how we could assess dialysis adequacy for home dialysis (home hemodialysis and peritoneal dialysis) and pediatric dialysis. 3. Performance Period for the ESRD QIP Measures
  
  Section 1881(h)(4)(D) of the Act requires the Secretary to establish a performance period with respect to a year, and for that performance period to occur prior to the beginning of such year.
  
  Because we are required under section 1881(h)(1)(A) to implement the payment reduction beginning with renal dialysis services furnished on or after January 1, 2012, the first performance period would need to occur prior to that date.
  
  In selecting a performance period, we need to allow sufficient time to calculate the provider/facility-specific scores, determine whether providers and facilities meet the performance standards and prepare the pricing files needed to implement applicable payment reductions beginning on January 1, 2012. Among potential performance periods in our model would be all or portions of 2010. However, we are also considering other performance periods. We seek public comments about performance periods and will propose a specific performance period in future rulemaking. 4. Methodology for Calculating the Total Performance Score for the ESRD
  
  QIP Measures
  
  Section 1881(h)(3)(A)(i) of the Act requires the Secretary to develop a methodology for assessing the total performance of each provider and facility based on the performance standards with respect to the measures selected for a performance period. Section 1881(h)(3)(A)(iii) states that the methodology must also include a process to weight the performance scores with respect to individual measures to reflect priorities for quality improvement, such as weighting scores to ensure that providers/facilities have strong incentives to meet or exceed anemia management and dialysis adequacy performance standards, as determined appropriate by the Secretary. In addition, section 1881(h)(3)(B) requires the Secretary to calculate separate performance scores for each measure.
  
  Finally, under section 1881(h)(3)(A)(ii), for those providers and facilities that do not meet (or exceed) the total performance score, the Secretary is directed to ensure that the application of the scoring methodology results in an appropriate distribution of reductions in payments to providers and facilities, with providers and facilities achieving the lowest total performance scores receiving the largest reductions.
  
  As discussed earlier, we are proposing to adopt for the initial performance period two anemia management measures and one hemodialysis adequacy measure that are currently used for DFC. In our model, for purposes of calculating the total performance of each provider and facility during the initial performance period, we are considering assigning 10 points to each of these measures. That is, if a provider or facility meets the performance standard for one measure, then it would receive 10 points for that measure, and if the provider or facility meets the performance standards for all three measures, it would receive a total performance score of 30 points.
  
  In our model, we are considering, for scoring purposes, that a provider or facility that does not meet the performance standard set for a measure would receive fewer than 10 points, with the exact number of points corresponding to how far from the set standard the provider/ facility's performance falls. Specifically, we are considering implementing a scoring methodology that subtracts 2 points for each 2 percentage point increment range the provider or facility's performance falls from the set performance standard. For example, if we used as the performance standard during the initial performance period the national average of 44 percent (based on 2007 DFC data) for one of the proposed anemia management measures (percentage of patients whose hemoglobin levels are greater than 12 g/dL), and a particular provider/facility had 46 percent of patients with hemoglobin levels greater than 12 g/dL during that period, the provider/facility would receive 8 points for its performance on the measure because 46 percent is within the first 2 percentage point increment range from 44 percent (see Table 42 below).
  
  However, applying the special rule for the initial performance period, as required by section 1881(h)(4)(E), the provider/facility's performance of 46 percent would become the performance standard for scoring purposes, and the provider/facility would receive 10 points for this measure (see Table 43 below).
  
  Under our model, providers and facilities that exceed the performance standards based on the national average for the period that the Secretary has determined and if their performance rate improved from the ``base utilization year'' then the provider or facility would receive additional points. Using the 2007 DFC data again to illustrate, if a provider/facility had 43 percent of patients with hemoglobin levels greater than 12 g/dL during the initial performance period, the provider/facility's performance would be better than the 2007 national average of 44 percent. In addition, if the provider/facility had a performance rate of 46 percent in the base utilization year then the provider/facility's performance of 43 percent for the initial performance period would also be better. Therefore, the provider/ facility would receive 12 points, which is an additional 2 points or a
  
  ``bonus'' (maximum bonus in this conceptual model) above the 10 points that could be received for meeting the performance standard of a measure. We believe providers and facilities should only receive additional points if they achieve higher levels of performance, that is, their actual performance exceeds the performance standard for the national average for the period that the Secretary has determined and improves above the base utilization year.
  
  As we noted above, the right side of Table 42 that represents the percentage of patients whose hemoglobin levels are greater than 12 g/ dL, illustrates how this scoring methodology could work for a provider/ facility for which, after applying the special rule, the performance standard for the proposed anemia management measures is the national performance rates for 2007. Likewise, Table 43 shows an example using a provider/facility-specific rate as the performance standard (after applying the special rule) for the proposed anemia management measures.
  
  In addition, Table 44 illustrates how the scoring methodology would work using the national performance rate for 2007 as the performance standard (after applying the special rule) for the proposed hemodialysis adequacy measure, and Table 45 shows an example of the scoring for the proposed hemodialysis adequacy measure using a facility-
  
  Page 50014
  
  specific rate as the performance standard (after applying the special rule).
  
  Note that the bolded rows show the performance standard for the applicable measure.

  Another example of how the scoring methodology might work follows below. The example assumes that Facility A achieves the following results during the initial performance period: 1. Anemia Management (less than 10 g/dL): Percentage of patients whose hemoglobin levels are less than 10 g/dL is 4 percent. 2. Anemia Management (more than 12 g/dL): Percentage of patients whose hemoglobin levels are greater than 12 g/dL is 43 percent. 3. Hemodialysis Adequacy: Percentage of patients whose URR levels are greater than 65 percent is 93 percent.
  
  The total performance score for Facility A would be 30 points.
  
  Facility A would receive bonus points for the anemia management (more than 12 g/dL) because the facility was above the national performance standard for the period determined by the Secretary, which in this example is 2007, and improved above the base utilization year, which is also 2007 in this example. However, the facility would not receive bonus points for the hemodialysis adequacy measure even though it improved from its base utilization year because it did not receive a percentage higher than the national average so the facility would receive a score of 10 points. Table 46 shows how the total performance score would be calculated for Facility A.

  We believe this total performance score methodology is appropriate for the initial performance period in the new ESRD QIP because it is basic and straightforward, allowing providers and facilities to familiarize themselves with the new pay-for-performance quality system.
  
  We plan to propose a total performance scoring methodology using the applicable set of measures in future rulemaking. However, we are seeking input on this model of a total performance score methodology to be applied for payment consequence year 2012.
  
  In our model, the initial scoring method weights each of the three proposed measures equally. As we stated above, we also plan to implement performance standards that include levels of achievement and improvement after the initial performance period. From a clinical perspective, we believe that providers and facilities may be concerned about whether they have as much opportunity to improve their performance on one of the proposed anemia management measures
  
  (hemoglobin levels less than 10 g/dL) as they might with the other two proposed measures. We are specifically soliciting comments on whether this is truly a concern among providers and facilities and, if so, whether we should consider assigning less weight to the measure based on that concern. We are also soliciting comments on how reassigning weights to measures in general (that is, less to some, more to others) might affect providers and facilities in terms of the payment consequence. 5. Application of Payment Reductions Using the Total Performance Score
  
  With respect to the providers/facilities that do not meet (or exceed) the total performance score, section 1881(h)(3)(A)(ii) of the
  
  Act requires the Secretary to ensure that the application of the scoring methodology results in an appropriate distribution of reductions in payments among providers and facilities achieving different levels of total performance scores, with providers and facilities achieving the lowest total performance scores receiving the largest reductions.
  
  Under our model, for payment consequence year 2012, we are thinking about implementing a sliding scale of payment reductions, where the payment reduction for the lowest total performance score would be 2.0 percent.
  
  Under our model, the minimum total performance score that providers and facilities would need to achieve in order to avoid a payment reduction would be 28 points. The range for the payment reductions is shown in Table 6:
  
  Table 47--Model Range of Payment Reductions
  
  Total performance score
  
  Percent of payment reduction
  
  28 to 30 Points........................... 0 Percent. 24 to 26 Points........................... .25 Percent. 20 to 22 Points........................... .50 Percent. 16 to 18 Points........................... .75 Percent. 12 to 14 Points........................... 1.0 Percent. 8 to 10 Points............................ 1.25 Percent. 4 to 6 Points............................. 1.50 Percent. 2 Points.................................. 1.75 Percent.
  
  Page 50016
  
  0 Points.................................. 2.0 Percent.
  
  Based on our example involving Facility A above, this facility would not receive a payment reduction in 2012 because it achieved a total performance score of 30 points.
  
  We recognize that under our model, a provider or facility that scores poorly on one measure could nonetheless receive no reduction in payment because the provider or facility also exceeded the performance standard for one or both of the other two measures. We are concerned about this possibility and are considering proposing that, for any measure for which a provider or facility receives 4 points or less, the provider/facility receive a 0.25 percent payment reduction even if it receives a total performance score of 28 points. We are seeking comments on our modeled methodology for applying payment reductions in 2012. 6. Public Reporting of Measures
  
  Section 1881(h)(6) requires the Secretary to establish procedures for making information regarding performance under the QIP available to the public, including information on the total performance score and performance scores for individual measures achieved by each provider and facility. Providers and facilities are required to have an opportunity to review this information prior to it being made public.
  
  The Secretary is also directed in section 1881(h)(6)(D) to post a list of providers and facilities on the CMS Web site that indicates the total performance score and the performance scores for individual measures achieved by each provider and facility. In addition, under section 1881(h)(6)(C), the Secretary is required to provide certificates to providers and facilities that indicate the total performance score achieved by the provider or facility, and the provider or facility must prominently display the certificate in patient areas.
  
  We plan to establish procedures for making information available to the public in a future rulemaking, but welcome comments on how to best implement these statutory requirements.
Collection of Information Requirements

Under the Paperwork Reduction Act of 1995, we are required to provide 60-day notice in the Federal Register and solicit public comment before a collection of information requirement is submitted to the Office of Management and Budget (OMB) for review and approval. In order to fairly evaluate whether an information collection should be approved by OMB, section 3506(c)(2)(A) of the Paperwork Reduction Act of 1995 requires that we solicit comment on the following issues:

The need for the information collection and its usefulness in carrying out the proper functions of our agency.

The accuracy of our estimate of the information collection burden.

The quality, utility, and clarity of the information to be collected.

Recommendations to minimize the information collection burden on the affected public, including automated collection techniques.

We are soliciting public comment on each of these issues for the following sections of this document that contain information collection requirements (ICRs):
1. ICRs Regarding a Low-Volume Adjustment (Sec. 413.232(f))
  
  As discussed in section VIII.A.2.b. of this proposed rule, to receive the low-volume adjustment, we propose that an ESRD facility must provide an attestation to the Medicare administrative contractor or fiscal intermediary that it has met the criteria to qualify as a low-volume facility. The Medicare administrative contractor or fiscal intermediary would verify the ESRD facility's attestation of their low- volume status using the ESRD facility's final-settled cost reports.
  
  The burden associated with the requirement is the time and effort necessary for an ESRD facility attesting as a low-volume facility to develop an attestation and submit it to the Medicare administrative contractor or fiscal intermediary. In the 2006 data analysis conducted by our contractor, UM-KECC, 489 ESRD facilities were identified as below the low-volume threshold of 3,000 treatments per year. Of these 488 facilities, 166 met the additional low-volume criteria as specified in Sec. 413.232 of this proposed rule. We estimate that it would require an administrative staff member from each low-volume facility 5 minutes to develop the attestation and a negligible amount of time to submit it to the Medicare administrative contractor or fiscal intermediary. We further estimate several dozen additional ESRD facilities may meet the criteria of a low-volume facility prior to implementation of the ESRD PPS and therefore, we round the total number of estimated low-volume facilities to 200. Therefore, we estimate that the total initial ESRD facility burden would be 16.6 hours.
2. ICRs Regarding Transition Period (Sec. 413.239)
  
  As discussed in section XIII.A. of this proposed rule, prior to
  
  January 1, 2011, an ESRD facility may make a one-time election to be excluded from the four-year transition to the ESRD PPS. That is, a facility may elect to be paid entirely based on the proposed ESRD PPS beginning January 1, 2011. Proposed Sec. 413.239(b) states that an
  
  ESRD facility may make a one-time election to be paid for items and services provided during transition based on 100 percent of the payment amount determined under Sec. 413.215 of this part, rather than based on the payment amount determined under paragraph (a) of this section.
  
  The section specifies that such election must be submitted to the facility's Medicare administrative contractor or fiscal intermediary no later than November 1, 2010.
  
  We estimate that it would require an accountant or financial management staff member from each of the 4,921 ESRD facilities 1 hour to simulate average aggregate payments under the proposed ESRD PPS and compare them to average aggregate payments under the current basic case-mix adjusted composite payment system, for a total of 4,921 hours.
  
  In addition, for those facilities electing to be excluded from the four-year transition, the burden associated with the requirement in proposed Sec. 413.239(b) is the time and effort necessary to develop an election and submit it to the Medicare administrative contractor or fiscal intermediary. We estimate that it would require an administrative staff member from each facility 15 minutes to develop the notice and a negligible amount of time to submit it. We estimate that 36 percent of the estimated 4,921 ESRD facilities, or 1,794 ESRD facilities, would make the election no later than November 1, 2010.
  
  Therefore, we estimate that the total one-time ESRD facility burden would be 448.5 hours.

Regulatory Impact Analysis
1. Overall Impact
  
  We have examined the impacts of this rule as required by Executive
  
  Order 12866 on Regulatory Planning and Review (September 30, 1993), the
  
  Regulatory Flexibility Act (RFA) (September 19, 1980, Pub. L. 96-354), section 1102(b) of the Social Security Act, section 202 of the Unfunded
  
  Mandates Reform Act of 1995 (Pub. L. 104-4), Executive Order 13132 on
  
  Federalism (August 4, 1999), and the Congressional Review Act (5 U.S.C. 804(2)).
  
  Executive Order 12866 directs agencies to assess all costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits
  
  (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). A regulatory impact analysis (RIA) must be prepared for major rules with economically significant effects ($100 million or more in any 1 year). This proposed rule is an economically significant rule because we estimate that the requirement under section 1881(b)(14)(A)(ii) of the Act--that the estimated total payments for renal dialysis services in CY 2011 equal 98 percent of the estimated total payments that would have been made if the ESRD PPS were not implemented--equates to an approximate $200 million decrease in payments to ESRD facilities in CY 2011. In addition, given this estimated impact, this proposed rule also is a major rule under the Congressional Review Act. Accordingly, we have prepared a RIA that to the best of our ability presents the costs and benefits of the proposed rule. We request comments on the economic analysis provided in this proposed rule.
  
  The RFA requires agencies to analyze options for regulatory relief of small businesses if a rule has a significant impact on a substantial number of small entities. For purposes of the RFA, approximately 21 percent of ESRD dialysis facilities are considered small entities according to the Small Business Administration's size standards, which considers small businesses those dialysis facilities having total
  
  Medicare revenues of $34.5 million or less in any 1 year, and 19 percent of dialysis facilities are nonprofit organizations. For more information on SBA's size standards, see the Small Business
  
  Administration's Web site at http://sba.gov/idc/groups/public/ documents/sba_homepage/serv_sstd_tablepdf.pdf (Kidney Dialysis
  
  Centers are listed as 621492 with a size standard of $34.5 million).
  
  For purposes of the RFA, we estimate that approximately 21 percent of
  
  ESRD facilities are small entities as that term is used in the RFA
  
  (which includes small businesses, nonprofit organizations, and small governmental jurisdictions). This amount is based on the number of ESRD facilities shown in the ownership category in the impact Table 48.
  
  Using the definitions in this ownership category, we consider the 550 facilities that are independent and the 471 facilities that are shown as hospital-based to be small entities. The ESRD facilities that are owned and operated by large dialysis organizations (LDOs) and regional chains would have total revenues more than $34.5 million in any year when the total revenues for all locations are combined for each business (individual LDO or regional chain). Overall, a hospital based
  
  ESRD facility (as defined by ownership type) is estimated to receive a 2.4 percent increase in payments under the new ESRD PPS for 2011. An independent facility (as defined by ownership type) is estimated to receive a 0.0 percent increase in payments under the proposed ESRD PPS for 2011. Therefore, the Secretary has determined that this proposed rule will not have a significant economic impact on a substantial number of small entities.
  
  The claims data we use to estimate payments to ESRD facilities in this RFA and RIA does not identify which dialysis facilities are part of an LDO, regional chain, or other type of ownership. As each individual dialysis facility has its own provider number and bills
  
  Medicare using this number. Therefore, in previous RFAs and RIAs presented in proposed and final rules that updated to the basic case- mix adjusted composite payment system, we considered each ESRD to be a small entity for purposes of the RFA. However, we conducted a special analysis for this proposed rule that enabled us to identify the ESRD facilities that are part of an LDO or regional chain. The results of this analysis are presented in the type of ownership category of impact
  
  Table 48.
  
  We do not believe ESRD facilities are operated by small government entities such as counties or towns with populations 50,000 or less and therefore, they are not enumerated or included in this initial RFA.
  
  Individuals and States are not included in the definition of a small entity.
  
  In addition, section 1102(b) of the Act requires us to prepare a regulatory impact analysis if a rule may have a significant impact on the operations of a substantial number of small rural hospitals. Any such regulatory impact analysis must conform to the provisions of section 603 of the RFA. For purposes of section 1102(b) of the Act, we define a small rural hospital as a hospital that is located outside of a metropolitan statistical area and has fewer than 100 beds. We do not believe this proposed rule has a significant impact on operations of a substantial number of small rural hospitals because most dialysis facilities are freestanding. While there are 188 rural hospital-based dialysis facilities, we do not know how many of them are based at hospitals with fewer than 100 beds. However, overall, the 189 rural hospital-based dialysis facilities will experience an estimated 1.7 percent increase in payments. As a result, this rule will not have a significant impact on small rural hospitals. Therefore, the Secretary has determined that this proposed rule will not have a significant impact on the operations of a substantial number of small rural hospitals.
  
  Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) also requires that agencies assess
  
  Page 50018
  
  anticipated costs and benefits before issuing any rule whose mandates require spending in any 1 year $100 million in 1995 dollars, updated annually for inflation. In 2009, that threshold is approximately $133 million. While dialysis facilities will be paid approximately $200 million less, we do not believe that this proposed rule includes any mandates that would impose spending costs on State, local, or tribal governments in the aggregate, or by the private sector, of $133 million.
  
  Executive Order 13132 establishes certain requirements that an agency must meet when it promulgates a proposed rule (and subsequent final rule) that imposes substantial direct requirement costs on State and local governments, preempts State law, or otherwise has Federalism implications. We do not believe this proposed rule will have a substantial direct effect on State or local governments, preempt State law, or otherwise have Federalism implications.
  
  Payment for ESRD Bad Debt
  
  The proposed changes to the ESRD bad debt payment in this proposed rule are not changes to the existing ESRD bad debt payment methodology and, therefore, there is no impact on ESRD payments from implementing the Rule of Construction described in Section 153(a)(4) of MIPPA and described elsewhere in this proposed rule.
2. Anticipated Effects 1. Effects on ESRD facilities
  
  To understand the impact of the changes affecting payments to different categories of ESRD facilities, it is necessary to compare estimated payments in CY 2011 under the current basic case-mix adjusted composite payment system (current payments) to estimated payments in CY 2011 under the proposed ESRD PPS, including payments to ESRD facilities paid a blended rate under the transition (new payments). To estimate the impact among various classes of ESRD facilities, it is imperative that the estimates of current payments and new payments contain similar inputs. Therefore, we simulated payments only for those ESRD facilities that we are able to calculate both current payments and new payments.
  
  ESRD providers were grouped into the categories based on characteristics provided in the Online Survey and Certification and
  
  Reporting (OSCAR) file and the most recent cost report data from the
  
  Healthcare Cost Report Information System (HCRIS). We also used the
  
  June 2008 update of CY 2007 National Claims History file as a basis for
  
  Medicare dialysis treatments and separately billable drugs and biologicals.
  
  Table 48 shows the impact of the proposed ESRD PPS compared to current payments to ESRD facilities under the basic case-mix composite payment system, including all separately billable items. Column A of impact Table 48 indicates the number of ESRD facilities for each impact category and column B indicates the number of dialysis treatments (in millions).

  \1\ Assumed that 1794 out of 4921 Facilities choose to be excluded from the transition based on comparison of payments under current system to payments under proposed ESRD PPS.
  
  If payments under a 100% fully implemented ESRD PPS are higher than payments under current system, we assumed that the facility would elect to be excluded from the transition.
  
  \2\ Includes hospital based facilities not reported to have large dialysis organization or regional chain ownership.
  
  \3\ Of the 489 Facilities with less than 3,000 treatments, only 166 qualify for the low-volume adjustment. The low-volume adjustment is mandated by Congress.
  
  The impact to these Low volume Facilites is a 16.6% increase in payments.
  
  \4\ These facilities that choose to retain their exception rate (either IEF or atypical) rather than be paid under the current basic case-mix adjusted composite payment system.
  
  Section 1881(b)(14)(E)(ii) of the Act provides all ESRD facilities with the option to make a one-time election to be excluded from the transition from the current payment system to the ESRD PPS (see section
  
  VII.E of this proposed rule for details of this statutory provision).
  
  Electing to be excluded from the 4-year transition means that the ESRD facility receives payments for renal dialysis services provided on or after January 1, 2011, based on 100 percent of the payment rate under the proposed ESRD PPS, rather than a blended rate based in part on the payment rate under the current payment system and in part on the payment rate under the proposed ESRD PPS. In order to estimate which
  
  ESRD facilities would and would not elect to opt out of the transition and receive payment based on 100 percent of the payment amount under the ESRD PPS, we are proposing to estimate both the aggregate payments for each ESRD facility under the proposed ESRD PPS (based on 100 percent of the payment amount under ESRD PPS) and payments in the first year of the transition (based on a blend of 25 percent of payments under the proposed ESRD PPS and 75 percent of payments under the current basic case-mix adjusted composite payment system). We then assume that facilities that would receive higher aggregate payments under the proposed ESRD PPS would elect to be paid based on 100 percent of the payment amount under the proposed ESRD PPS, and facilities that would receive higher aggregate payments under the first year of the transition (based on a blend of 25 percent of payments under the proposed ESRD PPS and 75 percent of payments under the current basic case-mix adjusted composite payment system) will elect to be paid under the transition. Based on these assumptions, we are estimating that 36 percent of ESRD facilities would choose to be excluded from the transition and we estimate that 64 percent of ESRD facilities would choose to be paid the blended rate under the transition.
  
  Additionally, in accordance with section 1881(b)(14)(E)(iii) of the
  
  Act and as described in section VII.E of this proposed rule, we are proposing to apply a transition budget-neutrality adjustment factor to all payments. The purpose of this factor is to make the estimated total payments under the ESRD PPS equal the estimated total payments that would have been made if there had been no transition. We estimate this factor to be 0.970. Since the same factor would be applied to all payments, including the blended payment rates under the transition, the effect of the transition budget neutrality adjustment factor is the same for all impact categories.
  
  The overall effect of the proposed ESRD PPS, in the first year of the transition, is shown in column C. This effect is determined by comparing total estimated payments under the proposed ESRD PPS, which includes blended payments and payments that are computed using our assumption that 36 percent of ESRD facilities would elect to be paid 100 percent ESRD PPS and 64 percent of ESRD facilities would elect to go through the transition. These payments have also been adjusted to reflect the proposed transition budget-neutrality adjustment factor.
  
  Total payments are then compared to payments that would have been made to facilities for renal dialysis services provided during CY 2011 under the basic case-mix adjusted composite payment system plus items and services separately billable under Title XVIII, including ESRD-related
  
  Part D drugs. In column C, the aggregate impact on all facilities is a 2.0 percent reduction in payments, which reflects the statutory 98 percent budget neutrality provision. Hospital-based ESRD providers of services show a 2.1 percent increase because as a group they receive higher payments under the proposed ESRD PPS than they would receive under the current system. We believe that the model used to create the proposed ESRD PPS adjustment factors more accurately predicts costs for this provider category. Facilities with less than 3,000 treatments show a 5.1 percent increase in payments under the proposed ESRD PPS because many of these facilities are eligible to receive the low-volume adjustment, which is a 20.2 percent adjustment per treatment. As with hospital-based ESRD providers of services, we believe that the model more
  
  Page 50020
  
  accurately predicts costs for this category. Facilities that chose to retain a composite rate exception in the current system show a 5.2 percent increase in payments under the proposed ESRD PPS. This may be explained by the fact that the current basic case-mix adjusted composite payment system does not completely account for their higher costs and that the proposed ESRD PPS more accurately accounts for the higher costs of these facilities as a group. The largest decrease in payments under the proposed ESRD PPS is for facilities with more than 50 percent pediatric patients which will experience a 3.6 percent decrease. We believe this decrease may be a result of the current system overpaying for pediatric patients, rather than the proposed ESRD
  
  PPS underpaying this group of facilities. As described in more detail in section IX of this proposed rule, the current system provides a 1.62 increase factor for pediatric patients. This factor was developed using cost per treatment for pediatric facilities that had applied for and received an exception under the current system. The current 1.62 adjustment factor was intended as a temporary adjustment and we stated our intention to refine this adjustment (69 FR 66327). We believe that the proposed pediatric patient adjustments under the proposed ESRD PPS provide a more accurate estimate of costs for these pediatric patients and therefore this provider category because they are now empirically driven and tied to the proposed ESRD PPS base rate. While this provider category will experience a decrease in payments under the proposed ESRD
  
  PPS as compared to the current system, we believe the transition to the
  
  ESRD PPS will provide a more gradual decrease.
  
  Column D shows the effect if all ESRD facilities were paid 100 percent of the proposed ESRD PPS. In this column, we are showing a hypothetical effect, as the statute provides for a 4-year transition to a fully implemented ESRD PPS. We show this column as a comparison to column C, in order to show how each impact category would have been effected if the ESRD PPS had been fully implemented in 2011. In column
  
  D, the overall effect for all facilities in aggregate is a 2.0 percent reduction, which reflects the statutory 98 percent budget neutrality provision. As with column C, we see the same categories of ESRD facilities most impacted by the proposed ESRD PPS. However, in column D the changes are generally more pronounced as those providers do not have the mitigating effect of the transition. Since column D shows the hypothetical effect if all ESRD facilities were to be paid 100 percent of the ESRD PPS in the first year of the transition, we do not need to apply the transition budget neutrality factor to column D. We believe that the comparison of columns C and D shows that the statutory option to transition does provide a more gradual affect for provider categories that receive lower payments under the proposed ESRD PPS, as well as the effect of the transition budget neutrality factor.
  
  Generally, providers that do well under the proposed ESRD PPS show larger increases in column D compared to column C because column D does not reflect the transition budget neutrality adjustment. However, many provider categories include a combination of providers that are estimated to receive higher payments under the proposed ESRD PPS and providers that are estimated to receive lower payments under the proposed ESRD PPS. We believe the comparison of columns C and D also shows that our proposal to apply the transition budget neutrality factor to all payments does not penalize any one group, but rather it evenly distributes the effect of this transition budget neutrality factor among all provider types. 2. Effects on Other Providers
  
  Under the proposed expanded bundle in the proposed ESRD PPS, other provider types such as laboratories, DME suppliers, and pharmacies would have to seek payment from ESRD facilities rather than Medicare.
  
  This is because under the proposed ESRD PPS, Medicare is paying ESRD facilities one combined payment for services that may have been separately paid by Medicare in the past. As discussed in more detail in section X.B of this proposed rule, the other provider types noted above may continue to provide certain ESRD-related services, however, beginning January 1, 2011, they may no longer bill Medicare directly and instead must seek payment from ESRD facilities. 3. Effects on the Medicare and Medicaid Programs
  
  We estimate that Medicare spending (total Medicare program payments) for ESRD facilities over the next five years would be as follows:
  
  Table 49--Estimated Payments
  
  Estimated
  
  Calendar year
  
  payments ($ in billions)
  
  2011....................................................
  
  7.9 2012....................................................
  
  8.2 2013....................................................
  
  8.5 2014....................................................
  
  8.9 2015....................................................
  
  9.2
  
  These estimates are based on current estimates of annual increases in the ESRDB market basket (discussed in detail in section XII of this proposed rule) of 2.6 percent for CY 2012 and CY 2013, and 2.7 for CY 2014 and CY 2015. In addition, we estimate that there will be an increase in fee-for-service Medicare beneficiary enrollment of 1.8 percent in CY 2011, 2.4 percent in CY 2012, 2.5 percent in CY 2013, 2.4 percent in CY 2014 and 2.3 percent in CY 2015.
  
  Consistent with the requirement for 98 percent budget neutrality in the initial year of implementation, we intend for estimated aggregate payments under the proposed ESRD PPS to equal 98 percent of the estimated aggregate payments that would have been made if the proposed
  
  ESRD PPS were not implemented. Our methodology for estimating payment for purposes of the budget neutrality calculation uses the best available data. 4. Effects on Medicare Beneficiaries
  
  Medicare beneficiaries are responsible for 20 percent coinsurance on Part B renal dialysis services. The overall effect for all ESRD facilities in aggregate is a 2 percent reduction in payments, which reflects the statutory 98 percent budget neutrality provision. Since
  
  Medicare beneficiaries are responsible for 20 percent coinsurance on
  
  Part B renal dialysis services, this overall 2 percent reduction translates to a 2 percent reduction to beneficiary coinsurance.
3. Alternatives Considered
  
  In developing this proposed rule, we considered a number of alternatives. We considered other adjustments, including race, modality, and site of service. We considered alternative adjustments to explain variation in cost and resource usage among patients and ESRD facilities. For example, we considered alternatives in the outlier policy, such as outlier percentages of 1.5, 2, 2.5, to 3 percent, rather than the proposed 1 percentage policy. We also considered a monthly payment, but instead proposed a per treatment payment.
  
  We have discretion on some of the adjustments we are proposing, however this has no impact on the aggregate amount of spending in the first year of

  the ESRD PPS (CY 2011). The statute requires a low-volume adjustment of at least 10 percent and an outlier policy. However, the statute did provide the Secretary with discretion in defining low-volume facilities and establishing an outlier policy. These issues are discussed in sections VIII.C and X.A, respectively. The sections referenced also discuss our rationale for the policy decisions we made.
4. Accounting Statement and Table
  
  Whenever a rule is considered a significant rule under Executive
  
  Order 12866, we are required to develop an Accounting Statement showing the classification of the expenditures associated with the provisions of this proposed rule.
  
  Table 50, below provides our best estimate of the decrease in CY 2011 Medicare payments under the ESRD PPS as a result of the changes presented in this proposed rule based on the best available data. The expenditures are classified as a transfer to the Federal Government of
  
  $160 million dollars (or as a savings to the Medicare Program) and as a transfer to beneficiaries of $40 million.

  Beneficiaries to the ESRD Provider.
5. Conclusion
  
  The impact analysis shows an overall decrease in payments to all
  
  ESRD facilities for renal dialysis services of 2.0 percent. This is because of the statutory requirement that payments under the ESRD PPS in 2011 equal 98 percent of what ESRD facilities would have received were the ESRD PPS not implemented (or 98 percent of payments to ESRD facilities under the current payment system).

    * * * * * 6. Section 413.171 is added to read as follows:
    
    Sec. 413.171 Definitions.
    
    For purposes of this subpart, the following definitions apply:
    
    Base rate. The average payment amount per-treatment, standardized to remove the effects of case-mix and area wage levels and further reduced for budget neutrality and the outlier percentage. The base rate is the amount to which the patient-specific case-mix
    
    Page 50022
    
    adjustments and any ESRD facility adjustments described in Sec. 413.230, if applicable, are applied.
    
    Composite Rate Services. Items and services used in the provision of outpatient maintenance dialysis for the treatment of ESRD and included in the composite rate established under section 1881(b)(7) and section 1881(b)(12) of the Act, the basic case-mix adjusted composite payment system.
    
    ESRD facility. An ESRD facility is an independent facility or a hospital-based provider of services (as described in Sec. 413.174(b) and (c) of this chapter) including facilities that have a self-care dialysis unit that furnishes only self-dialysis services as defined in
    
    Sec. 494.10 of this chapter and meets the supervision requirements described in part 494 of this chapter, and that furnishes institutional dialysis services and supplies under Sec. 410.50 of this chapter.
    
    New ESRD facility. A new ESRD facility is an ESRD facility (as defined above), that is certified for Medicare participation on or after January 1, 2011.
    
    Renal dialysis services. Effective January 1, 2011, the following items and services are considered ``renal dialysis services,'' and paid under the ESRD prospective payment system under section 1881(b)(14) of the Act:
    
    (1) Items and services included in the composite rate for renal dialysis services as of December 31, 2010;
    
    (2) Erythropoiesis stimulating agents and any oral form of such agents that are furnished to individuals for the treatment of ESRD;
    
    (3) Other drugs and biologicals that are furnished to individuals for the treatment of ESRD and for which payment was (prior to January 1, 2011) made separately under Title XVIII of the Act (including drugs and biologicals with only an oral form), and any oral equivalent form of such drug and biological;
    
    (4) Diagnostic laboratory tests and other items and services not described in paragraph (1) of this definition that are furnished to individuals for the treatment of ESRD.
    
    Separately Billable Items and Services. Items and services used in the provision of outpatient maintenance dialysis for the treatment of individuals with ESRD that were, prior to January 1, 2011, separately payable under Title XVIII of the Act and not included in the payment systems established under section 1881(b)(7) and section 1881(b)(12) of the Act. 7. Section 413.172 is amended by revising paragraph (a), paragraph
    
    (b) introductory text, and paragraph (b)(1) to read as follows:
    
    Sec. 413.172 Principles of prospective payment.

  4. Establishment of rates. CMS establishes prospective payment rates for ESRD facilities using a methodology that--
    
    (1) Differentiates between hospital-based providers of services and independent ESRD facilities for items and services furnished prior to
    
    January 1, 2009, under section 1881(b)(7) and section 1881(b)(12) of the Act;
    
    (2) Does not differentiate between hospital-based providers of services and independent ESRD facilities for items and services furnished on or after January 1, 2009; and
    
    (3) Requires the labor share be based on the labor share otherwise applied to independent ESRD facilities when applying the geographic index to hospital-based ESRD providers of services, on or after January 1, 2009.
    
    * * * * *
    
    (f) Additional payment for separately billable drugs and biologicals. Prior to January 1, 2011, CMS makes additional payment directly to an ESRD facility for certain ESRD-related drugs and biologicals furnished to ESRD patients. Effective January 1, 2011, as specified in section 1881(b)(14) of the Act, payment to an ESRD facility for certain ESRD-related drugs and biologicals furnished to
    
    ESRD patients on or after January 1, 2011 is incorporated within the prospective payment system rates established by CMS in Sec. 413.230 and separate payment will no longer be provided.
    
    * * * * *
    
    (3) For drugs furnished prior to January 1, 2006, payment is made to hospital-based ESRD providers of services on a reasonable cost basis. Effective January 1, 2006, and prior to January 1, 2011, payment for drugs furnished by a hospital-based ESRD provider of service is based on the methodology specified in Sec. 414.904 of this chapter.
    
    (4) For drugs furnished prior to January 1, 2006, payment is made to independent ESRD facilities based on the methodology specified in
    
    Sec. 405.517 of this chapter. Effective January 1, 2006, and prior to
    
    January 1, 2011, payment for drugs and biologicals furnished by independent ESRD facilities is based on the methodology specified in
    
    Sec. 414.904 of this chapter.
    
    (5) Effective January 1, 2011, payment for drugs and biologicals furnished by ESRD facilities as defined in Sec. 413.171(c) is included in the ESRD prospective payment system rate established in Sec. 413.230. 9. Section 413.176 is revised to read as follows:
    
    Sec. 413.176 Amount of payments.
    
    For items and services, for which payment is made under section 1881(b)(7), section 1881(b)(12), and section 1881(b)(14)of the Act:

  5. If the beneficiary has incurred the full deductible applicable under Part B of Medicare before the dialysis treatment, Medicare pays the ESRD facility 80 percent of its prospective rate.
    
    (b) If the beneficiary has not incurred the full deductible applicable under Part B of Medicare before the dialysis treatment, CMS subtracts the amount applicable to the deductible from the ESRD facility's prospective rate and pays the facility 80 percent of the remainder, if any. 10. Section 413.178 is amended by revising paragraph (d) to read as follows:
    
    Sec. 413.178 Bad debts.

    (4) For ESRD facilities that are paid a blended rate for renal dialysis services provided during the transition described in Sec. 413.235(a) of this part, any existing exceptions for isolated essential facilities, self dialysis training costs, atypical service intensity
    
    (patient mix) and pediatric facilities is used as the payment amount in place of the composite rate, for exceptions in effect prior to January 1, 2011 and will be terminated for ESRD services furnished on or after
    
    January 1, 2014.
    
    (5) For ESRD facilities that, in accordance with Sec. 413.235(b) of this part, elect to be paid for renal dialysis services provided during the transition based on 100 percent of the payment amount determined under Sec. 413.220 any existing exceptions for isolated essential facilities, self dialysis training costs, atypical service intensity (patient mix) and pediatric facilities are terminated for
    
    ESRD services furnished on or after January 1, 2011. 12. Section 413.195 is added to read as follows:
    
    Sec. 413.195 Limitation on review.

Except as otherwise provided under Sec. 413.235 of this part, effective January 1, 2011, ESRD facilities receive a predetermined per treatment payment amount for items and services, specified under section 1881(b)(14) of the Act and as defined in Sec. 413.217 of this part, furnished to Medicare Part B fee-for-service beneficiaries.
    
    (b) The per-treatment payment amount is the product of the per treatment base rate described in Sec. 413.220 plus the applicable adjustments described in Sec. 413.231 through Sec. 413.237 of this part.
    
    (c) In addition to the per-treatment payment amount, as described in Sec. 413.215(a) of this part, the ESRD facility may receive payment for bad debts of Medicare beneficiaries as specified in Sec. 413.178 of this part. 16. Section 413.217 is added to subpart H to read as follows:
    
    Sec. 413.217 Items and services included in the ESRD prospective payment system.
    
    The following items and services are included in the ESRD prospective payment system effective January 1, 2011:
    
    (
  8. Renal dialysis services as defined in Sec. 413.171; and
    
    (b) Home dialysis services, support, and equipment as identified in
    
    Sec. 410.52 of this chapter. 17. Section 413.220 is added to subpart H to read as follows:
    
    Sec. 413.220 Methodology for calculating the per-treatment base rate under the ESRD prospective payment system effective January 1, 2011.
    
    (
  9. Data sources. The methodology for determining the per treatment base rate under the ESRD prospective payment system utilized:
    
    (1) Medicare data available to estimate the average cost and payments for items and services.
    
    (2) ESRD facility cost report data capturing the average cost per treatment.
    
    (3) The lowest per patient utilization calendar year as identified from Medicare claims for calendar years 2007, 2008, or 2009.
    
    (4) Wage index values used to adjust for geographic wage levels described in Sec. 413.231 of this part.
    
    (5) An adjustment factor to account for the most recent estimate of increases in the prices of an appropriate market basket of goods and services provided by ESRD facilities.
    
    (b) Determining the per treatment base rate for calendar year 2011.
    
    The ESRD prospective payment system combines payments for the composite rate items and services as defined in
    
    Page 50024
    
    Sec. 413.171 of this part and the items and services that, prior to
    
    January 1, 2011, were separately billable items and services, as defined in Sec. 413.171 of this part, into a single per treatment base rate developed from 2007 claims data. The steps to calculating the per- treatment base rate for 2011 are as follows:
    
    (1) Average payments in CY 2007, 2008 or 2009. CMS computes the average Medicare allowable payment for composite rate items and services and separately billable items and services furnished in CY 2007, 2008 or 2009 to yield a per treatment base rate for 2007, 2008 or 2009 and selects the year with the lowest per patient utilization.
    
    (2) Update of per treatment base rate to 2011. CMS updates the per- treatment base rate under the ESRD prospective payment system in order to reflect estimated per treatment costs in 2011.
    
    (3) Standardization. CMS applies a reduction factor to the per treatment base rate to reflect estimated increases resulting from the facility-level and patient-level adjustments applicable to the case as described in Sec. 413.231 through Sec. 413.237 of this part.
    
    (4) Outlier percentage. CMS reduces the per treatment base rate by 1 percent to account for the proportion of the estimated total payments under the ESRD Prospective Payment System that are outlier payments as described in Sec. 413.237 of this part.
    
    (5) Budget neutrality. CMS adjusts the per treatment base rate so that the aggregate payments in 2011 are estimated to be 98 percent of the amount that would have been made under title XVIII of the Social
    
    Security Act if the ESRD prospective payment system described in Sec. 413.210 through Sec. 413.239 of this part were not implemented.
    
    (6) First Four Years of the ESRD Prospective Payment System. During the first four years of ESRD prospective payment system (January 1, 2011 to December 31, 2014), CMS adjusts the per-treatment base rate in accordance with Sec. 413.239(d). 18. Section 413.230 is added to subpart H to read as follows:
    
    Sec. 413.230 Determining the per treatment payment amount.
    
    The per-treatment payment amount is the product of the per treatment base rate established in Sec. 413.220, the facility-level and patient-level adjustments described in Sec. 413.231, Sec. 413.232 and Sec. 413.235 of this part, and any outlier payment under Sec. 413.237. 19. Section 413.231 is added to subpart H to read as follows:
    
    Sec. 413.231 Adjustment for wages.
    
    (
  10. CMS adjusts the labor portion of the base rate to account for geographic differences in the area wage levels using an appropriate wage index (established by CMS) which reflects the relative level of hospital wages and wage-related costs in the geographic area in which the ESRD facility is located.
    
    (b) The application of the wage index is made on the basis of the location of the ESRD facility in an urban or rural area as defined in this paragraph (b).
    
    (1) Urban area means a Metropolitan Statistical Area or a
    
    Metropolitan division (in the case where a Metropolitan Statistical
    
    Area is divided into Metropolitan Divisions), as defined by OMB.
    
    (2) Rural area means any area outside an urban area. 20. Section 413.232 is added to subpart H to read as follows:
    
    Sec. 413.232 Low-volume adjustment.
    
    (
  11. CMS adjusts the base rate for low-volume ESRD facilities, as defined in paragraph (b) of this section.
    
    (b) Definition of low-volume facility. A low-volume facility is an
    
    ESRD facility that:
    
    (1) Furnished less than 3,000 treatments in each of the 3 years preceding the payment year; and
    
    (2) Has not opened, closed, or had a change in ownership in the 3 years preceding the payment year.
    
    (c) For the purpose of determining the number of treatments under paragraph (b)(1) of this section, the number of treatments considered furnished by the ESRD facility shall be equal to the aggregate number of treatments furnished by the ESRD facility and the number of treatments furnished by other ESRD facilities that are both:
    
    (1) Under common ownership with, and
    
    (2) 25 miles or less from the ESRD facility in question.
    
    (d) The determination under paragraph (c) of this section does not apply to an ESRD facility that was in existence and certified for
    
    Medicare participation prior January 1, 2011.
    
    (e) Common ownership means the same individual, individuals, entity, or entities, directly, or indirectly, own 5 percent or more of each ESRD facility.
    
    (f) To receive the low-volume adjustment, an ESRD facility must provide an attestation statement to the fiscal intermediary/MAC that the facility has met all the criteria as established in paragraphs (a),
    
    (b), (c), and (d) of this section. 21. Section 413.235 is added to subpart H to read as follows:
    
    Sec. 413.235 Patient-level adjustments.
    
    Adjustments to the per-treatment base rate may be made to account for variation in case-mix. These adjustments reflect patient characteristics that result in higher costs for ESRD facilities.
    
    (
  12. CMS adjusts the per treatment base rate for adults to account for patient age, patient sex (female), body surface area, low body mass index, onset of dialysis (new patient), and co-morbidities, as specified by CMS.
    
    (b) CMS adjusts the per treatment base rate for pediatric patients in accordance with section 1881(b)(14)(D)(iv)(I) of the Act, to account for patient age, treatment modality, and the presence of co- morbidities. 22. Section 413.237 is added to subpart H to read as follows:
    
    Sec. 413.237 Outliers.
    
    (
  13. The following definitions apply to this section.
    
    (1) ESRD outlier services are separately billable items and services as defined in Sec. 413.171 of this part and renal dialysis service drugs proposed for inclusion in the ESRD prospective payment system that currently are covered under Medicare Part D.
    
    (2) Adult predicted ESRD outlier services Medicare allowable payment (MAP) amount means the predicted per-treatment case-mix adjusted amount for ESRD outlier services furnished to an adult beneficiary by an ESRD facility as defined in Sec. 413.171.
    
    (3) Pediatric predicted ESRD outlier services Medicare allowable payment (MAP) amount means the predicted per-treatment case-mix adjusted amount for ESRD outlier services furnished to a pediatric beneficiary by an ESRD facility as defined in Sec. 413.171.
    
    (4) Adult fixed dollar loss amount is the amount by which an ESRD facility's imputed per-treatment MAP amount for furnishing ESRD outlier services to an adult beneficiary must exceed the adult predicted ESRD outlier services MAP amount to be eligible for an outlier payment.
    
    (5) Pediatric fixed dollar loss amount: The amount by which an ESRD facility's imputed per-treatment MAP amount for furnishing ESRD outlier services to a pediatric beneficiary must exceed the pediatric predicted
    
    ESRD outlier services MAP amount to be eligible for an outlier payment.
    
    (6) Outlier Percentage: This term has the meaning set forth in
    
    Sec. 413.220(c)(4).
    
    (b) Eligibility for outlier payments:
    
    (1) Adult beneficiaries. An ESRD facility will receive an outlier payment for a treatment furnished to an adult beneficiary if the ESRD facility's per-
    
    Page 50025
    
    treatment imputed MAP amount for ESRD outlier services exceeds the adult predicted ESRD outlier services MAP amount plus the adult fixed dollar loss amount. To calculate the ESRD facility's per-treatment imputed MAP amount for an adult beneficiary, CMS divides the ESRD facility's monthly imputed MAP amount of providing ESRD outlier services to the adult beneficiary by the number of dialysis treatments furnished to the adult beneficiary in the relevant month. A beneficiary is considered an adult beneficiary if the beneficiary is 18 years old or older.
    
    (2) Pediatric beneficiaries. An ESRD facility will receive an outlier payment for a treatment furnished to a pediatric beneficiary if the ESRD facility's per-treatment imputed MAP amount for ESRD outlier services exceeds the pediatric predicted ESRD outlier services MAP amount plus the pediatric fixed dollar loss amount. To calculate the
    
    ESRD facility's per-treatment imputed MAP amount for a pediatric beneficiary, CMS divides the ESRD facility's monthly imputed MAP amount of providing ESRD outlier services to the pediatric beneficiary by the number of dialysis treatments furnished to the pediatric beneficiary in the relevant month. A beneficiary is considered a pediatric beneficiary if the beneficiary is under 18 years old.
    
    (c) Outlier payment amount: CMS pays 80 percent of the difference between:
    
    (1) The ESRD facility's per-treatment imputed MAP amount for the
    
    ESRD outlier services, and
    
    (2) The adult or pediatric predicted ESRD outlier services MAP amount plus the adult or pediatric fixed-dollar loss amount, as applicable. 23. Section 413.239 is added to subpart H to read as follows:
    
    Sec. 413.239 Transition period.
    
    (
  14. Duration of transition period and composition of the blended transition payment. ESRD facilities not electing under paragraph (b) of this section to be paid based on the payment amount determined under
    
    Sec. 413.230 of this part will be paid a per-treatment payment amount for renal dialysis services (as defined in Sec. 413.171 of this part) and home dialysis, provided during the transition as follows--
    
    (1) For services provided on and after January 1, 2011 through
    
    December 31, 2011, a blended rate equal to the sum of:
    
    (i) 75 percent of the payment amount determined under the ESRD payment methodology in effect prior to January 1, 2011 in accordance with section 1881(b)(12) of the Act and items and services separately paid under Part B; and
    
    (ii) 25 percent of the payment amount determined in accordance with section 1881(b)(14) of the Act;
    
    (2) For services provided on and after January 1, 2012 through
    
    December 31, 2012, a blended rate equal to the sum of:
    
    (i) 50 percent of the payment amount determined under the ESRD payment methodology in effect prior to January 1, 2011 in accordance with section 1881(b)(12) of the Act and items and services separately paid under Part B; and
    
    (ii) 50 percent of the payment rate determined in accordance with section 1881(b)(14) of the Act;
    
    (3) For services provided on and after January 1, 2013 through
    
    December 31, 2013, a blended rate equal to the sum of:
    
    (i) 25 percent of the payment amount determined under the ESRD payment methodology in effect prior to January 1, 2011 in accordance with section 1881(b) (12) of the Act and items and services separately paid under Part B; and
    
    (ii) 75 percent of the payment amount determined in accordance with section 1881(b)(14) of the Act;
    
    (4) For services provided on and after January 1, 2014, 100 percent of the payment amount determined in accordance with section 1881(b)(14) of the Act.
    
    (b) One-time election. Except as provided in paragraph (b)(2) of this section, ESRD facilities may make a one-time election to be paid for items and services provided during the transition based on 100 percent of the payment amount determined under Sec. 413.215 of this part, rather than based on the payment amount determined under paragraph (a) of this section.
    
    (1) Except as provided in paragraph (b)(3) of this section, the election must be received by each ESRD facility's Medicare administrative contractor (MAC) by November 1, 2010, regardless of any postmarks or anticipated delivery dates. Requests received, postmarked, or delivered by other means after November 1, 2010 will not be accepted. Once the election is made, it may not be rescinded.
    
    (2) If the ESRD facility fails to submit an election, or the ESRD facility's election is not received by CMS by November 1, 2010, payments to the ESRD facility for items and services provided during the transition will be based on the payment amounts determined under paragraph (a) of this section.
    
    (3) ESRD facilities that become certified for Medicare participation and begin to provide renal dialysis services, as defined in Sec. 413.171 of this part, between November 1, 2010 and December 31, 2010, must notify their designated contractor (MAC) of their election choice at the time of enrollment.
    
    (c) Treatment of new ESRD facilities. For renal dialysis services as defined in Sec. 413.171, provided during the transition, new ESRD facilities as defined in Sec. 413.171, are paid based on the per- treatment payment amount determined under Sec. 413.215 of this part.
    
    (d) Transition budget-neutrality adjustment. During the first 3 years of the transition (January 1, 2011 through December 31, 2013),
    
    CMS adjusts all payments, including payments under this section, under the ESRD prospective payment system so that the estimated total amount of payment equals the estimated total amount of payments that would otherwise occur without such a transition. 24. Section 413.241 is added to subpart H to read as follows:
    
    Sec. 413.241 Pharmacy arrangements.
    
    Effective January 1, 2011, the ESRD facility that enters into an arrangement with a pharmacy to furnish renal dialysis service drugs must ensure that the pharmacy is located such that it has the capability to provide all classes of renal dialysis service drugs to patients in a timely manner.
