AOR/BOR File [ZIP, 1MB] : This zip file for the FY 2020 proposed rule contains one excel spreadsheet with multiple tabs: one for the After Outliers Removed (AOR) and one 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.

  3. Case Mix Index File [ZIP, 44KB] : 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 2018, using the V35 Grouper).
  4. FY 2020 Proposed Rule: HCRIS Data File - Opens in a new window : CMS uses hospital cost report data from the Medicare Cost Report, Hospital Form 2552-10, to calculate the Cost-to-Charge Ratios (CCRs) used in the cost based MS-DRG relative weight methodology. The database for the Medicare cost reports is the Healthcare Cost Report Information System (HCRIS). The CCRs used in the calculation of the MS‑DRG relative weights for the FY 2020 IPPS Proposed Rule are derived from the December 31, 2018 quarterly update of the FY 2017 HCRIS.

  15. Hospital Readmissions Reduction Program Supplemental Data File: While the proposed rule discusses the supplemental data file, we have not updated the supplemental data file because the proposed readmissions payment adjustment factors are not available at this time because hospitals have not yet had the opportunity to review and correct the data before the data are made public under our policy regarding the reporting of hospital-specific data, and the information would be the same as the FY 2019 final rule supplemental data file. Therefore, we refer readers to the FY 2019 IPPS/LTCH PPS final rule supplemental file, which has the most recent finalized payment adjustment factor components and is the same data as would have been used to create the FY 2020 IPPS/LTCH PPS proposed rule supplemental data file.
