About these rankings

Rankings use the 2026 release of CMS Care Compare data. Hospitals share a rank (“T”) when their values are equal, and only hospitals with a reported value for the sorted measure are ranked. Shading compares each value with every hospital in the country, so it doesn’t change with your filters. Small differences are often not statistically meaningful; use the methodology and glossary for context.

Approximate combined change to the hospital's Medicare inpatient payments from the three pay-for-performance programs, added together: the readmissions penalty, the value-based purchasing bonus or penalty, and the 1% cut for hospital-acquired conditions.

Value-based purchasing score
Hospital Value-Based Purchasing Total Performance Score (0-100), from outcomes, safety, patient experience and efficiency. It sets a Medicare bonus or penalty..
