## Abstract

This interim final rule with comment period implements revised Medicare severity long-term care diagnosis-related group (MS-LTC-DRG) relative weights for payment under the long-term care hospital (LTCH) prospective payment system (PPS) for federal fiscal year (FY) 2009. We are revising the MS-LTC-DRG relative weights for FY 2009 due to the misapplication of our established methodology in the calculation of the budget neutrality factor. The revised FY 2009 MS-LTC-DRG relative weights are effective for the remainder of FY 2009 (that is, from June 3, 2009 through September 30, 2009).
