Profile Definitions and Methodology

Inpatient Utilization Statistics by Medical Service

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.
