Hospital Readmission Penalty (HRRP)

How It Works

The Hospital Readmissions Reduction Program (HRRP) was authorized by Section 3025 of the Affordable Care Act and began imposing payment penalties October 1, 2012 (FY2013). Its design is simple but powerful: CMS calculates an Excess Readmission Ratio (ERR) for each applicable condition at each hospital, comparing observed to expected 30-day readmissions after risk adjustment for patient age, sex, and clinical comorbidities. Ratios above 1.0 indicate worse-than-expected readmissions. The hospital's penalty is the weighted aggregate of its ERRs across the six tracked conditions (AMI, HF, pneumonia, COPD, elective THA/TKA, CABG), scaled to produce a payment reduction capped at 3% of base operating DRG payments. In the first year (FY2013) the cap was 1%, rising to 2% in FY2014 and 3% from FY2015 onward. Every year since launch, about two-thirds of eligible hospitals have received some penalty. In FY2024, 2,273 hospitals were penalized for a total payment reduction of approximately $320 million, with 39 hospitals hitting the 3% maximum. Hospitals serving the most socioeconomically disadvantaged populations historically received disproportionate penalties, since low-income patients readmit more often even after clinical risk adjustment. The 21st Century Cures Act mandated stratification into five peer groups based on proportion of dual-eligible (Medicare-Medicaid) patients starting FY2019, which reduced disparate impact but did not eliminate it. Penalty avoidance has driven a multi-billion-dollar transitional care industry: embedded case managers, home health partnerships with agencies like BAYADA and Kindred, telephonic nurse outreach, and readmission risk scoring using LACE and other algorithms. Studies show HRRP reduced readmissions 2-3 percentage points but some research suggests unintended mortality increases in heart failure, an ongoing controversy.
