For patients 18 years of age and older, the number of acute inpatient stays during the measurement year that were followed by an unplanned acute readmission for any diagnosis within 30 days and the predicted probability of an acute readmission. Data are reported in the following categories:
1. Count of Index Hospital Stays* (denominator)
2. Count of 30-Day Readmissions (numerator)
3. Average Adjusted Probability of Readmission
*An acute inpatient stay with a discharge during the first 11 months of the measurement year (e.g., on or between January 1 and December 1).
The 30-day Hospital-Wide, All-Cause Unplanned Readmission (HWR) Rate for the Merit-Based Incentive Payment System (MIPS) Groups measure is a risk-standardized readmission rate for beneficiaries age 65 or older who were hospitalized and experienced an unplanned readmission for any cause to a short-stay acute-care hospital within 30 days of discharge. The measure attributes readmissions to up to three MIPS participating clinician groups, as identified by their Medicare Taxpayer Identification Number (TIN) and assesses each group’s readmission rate. This clinician group-level, risk-standardized, all-cause unplanned readmission measure is a re-specified version of the hospital-level measure, “Hospital-wide Allcause Unplanned Readmission Measure” (NQF 1789), which is currently reported within the Inpatient Quality Reporting (IQR) program. This measure will replace the existing All-Cause Readmission (ACR) measure currently in use in QPP.
