We are revising the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital-related costs to implement changes arising from our continuing experience with these systems, and to implement certain provisions made by the Deficit Reduction Act of 2005 (Pub. L. 109-171), the Medicare Improvements and Extension Act under Division B, Title I of the Tax Relief and Health Care Act of 2006 (Pub. L. 109-432), and the Pandemic and All Hazards Preparedness Act (Pub. L. 109-417). In addition, in the Addendum to this final rule with comment period, we describe the changes to the amounts and factors used to determine the rates for Medicare hospital inpatient services for operating costs and capital-related costs. We also are setting forth the rate of increase limits for certain hospitals and hospital units excluded from the IPPS that are paid on a reasonable cost basis subject to these limits, or that have a portion of a prospective payment system payment based on reasonable cost principles. These changes are applicable to discharges occurring on or after October 1, 2007. In this final rule with comment period, as part of our efforts to further refine the diagnosis related group (DRG) system under the IPPS to better recognize severity of illness among patients, for FY 2008, we are adopting a Medicare Severity DRG (MS DRG) classification system for the IPPS. We are also adopting the structure of the MS-DRG system for the LTCH prospective payment system (referred to as MS-LTC-DRGs) for FY 2008. Among the other policy decisions and changes that we are making, we are making changes related to: limited revisions of the reclassification of cases to MS-DRGs, the relative weights for the MS-LTC-DRGs; applications for new technologies and medical services add-on payments; the wage data, including the occupational mix data, used to compute the FY 2008 wage indices; payments to hospitals for the indirect costs of graduate medical education; submission of hospital quality data; provisions governing the application of sanctions relating to the Emergency Medical Treatment and Labor Act of 1986 (EMTALA); provisions governing the disclosure of physician ownership in hospitals and patient safety measures; and provisions relating to services furnished to beneficiaries in custody of penal authorities.
