This field represents the Hospital Readmission Reduction (HRR) Program Payment Amount. The amount is the reduction to the claim for a readmission.
The ACA (Section 3025) requires CMS to reduce payments to subsection (d) Inpatient Prospective Payment System (IPPS) hospitals with excess readmissions. There is a variable that indicates whether the hospital was excluded from the HRR program (see CLM_HRR_PRTCPNT_IND_CD). This percentage reduction is applied to the base operating DRG amount(defined as the wage-adjusted DRG payment plus new technology add-on payments).
Additional information is available on the CMS "Hospital Value-Based Purchasing" website.
This amount is based on a percent (CLM_HRR_ADJSTMT_PCT).
This initiative began in 4th Quarter of 2012 (i.e., beginning of Federal fiscal year 13).
This field was new in 2012, and is null/missing for all previous years.
