FY 2023 Final Rule Data Files

  1. FY 2023 Final Rule Impact File (ZIP): This file contains data elements by provider that were used in calculating the FY 2023 rates and impacts.
  2. AOR/BOR File (ZIP): Since we are finalizing to calculate the relative weights for FY 2023 by calculating two sets of weights (and then averaging the two sets of relative weights), one including all claims and one excluding COVID-19 claims, we are providing an AOR/BOR file for each calculation. The excel spreadsheet in each zip file contains multiple tabs: Tabs for the After Outliers Removed (AOR) and tabs for the Before Outliers Removed (BOR). There are also two tabs containing the variable descriptions. The variables in these files are used in the calculations of the relative weights as well as other calculations for the inpatient PPS. This file also contains the arithmetic and geometric mean lengths of stay which was previously included in Tables 7A and 7B.
  3. Case Mix Index File (ZIP): This file contains the non-transfer adjusted case mix index (CMI) based on the MS-DRGs billed on the claim in the year the claim was incurred (that is, during FY 2021, using the V38 Grouper).
