Readmissions and return visits

Centers for Medicare & Medicaid Services · Medicare patients

Medicare's readmission program

Excess readmission ratio: this hospital's predicted readmissions divided by the number expected for a typical hospital with the same patients. Above 1.00 means more readmissions than expected. 2 of 4 conditions are above 1.00.

ConditionRatioPatientsReadmissions
Pneumonia 1.012 128 More than expected
COPD 1.008 76 More than expected
Heart failure 0.998 101 Fewer than expected
Hip or knee replacement 0.933 – Fewer than expected

Readmission rates count Medicare patients who were admitted to any acute-care hospital within 30 days of leaving this one, adjusted for how sick they were. "Better" or "worse" means CMS found the difference from the national rate statistically significant; most hospitals are "no different". Return-day and outpatient-surgery measures compare the hospital with what CMS expected for its own patients. The Readmissions Reduction Program ratios are shown as CMS publishes them; whether a hospital's payments are reduced depends on how its ratios compare with similar hospitals, so a ratio above 1.00 alone doesn't mean a penalty. About the data.

Medicare spending and payment programs

Centers for Medicare & Medicaid Services

Hospital-acquired conditions · FY 2026
No penalty
Not in the worst-performing quarter on infections and patient-safety problems. 719 of 3,012 hospitals were penalized.

The Hospital-Acquired Condition Reduction Program cuts Medicare payments by 1% for the quarter of hospitals with the worst scores. The Hospital Value-Based Purchasing Program withholds a small share of every hospital's Medicare payments and pays it back according to the total performance score. A spending ratio of 1.00 equals the national median; spending reflects prices, the services patients received and care after discharge, not quality. Some hospitals, such as critical access, children's and cancer hospitals, are not part of these programs. About the data.
