Under the Hospital Readmissions Reduction (HRR) Program, the amount used to identify the readmission adjustment factor that will be applied.
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.
The actual dollar amount of the adjustment that applied to the claim is found in the variable called CLM_HRR_ADJSTMT_PMT_AMT.
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.
