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. All text files in the zip file are for 508 compliance.

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 2024 IPPS Proposed Rule are derived from the December 31, 2022 quarterly update of the FY 2021 HCRIS. (HCRIS is updated on a quarterly basis).
