Profile Definitions and Methodology

All information in this report is taken from the Medicare Provider Analysis and Review (MedPAR) file which is updated annually by CMS based on the federal fiscal year.  The file includes billing data for 100% of all Medicare fee-for-service claims for discharges during the twelve months ending September 30.  The report is consistent with CMS Data Release policies.

Medical service categories are based on groupings of patient MS-DRGs.  Click on any medical service in the report to see the MS-DRGs that are combined to define the category.

• Number of Medicare Discharges - total number of IPPS claims for the MS-DRG.
• Average Length of Stay - total patient days divided by the number of discharges.
• Average Charges - total gross charges divided by the number of discharges
• Medicare CMI - the Medicare case mix index (CMI) is based on the Medicare Hospital Inpatient Prospective Payment System for the corresponding federal fiscal year.  The CMI for long term acute care (LTAC) hospitals reflects LTAC MS-DRGs.
