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.

Net Medicare quality adjustment
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. Inpatient prospective payment system hospitals only; Maryland hospitals are exempt..

Heart attack death rate

Heart failure death rate

Hospital-wide readmission rate
Rate of unplanned readmission within 30 days, all conditions. From 2025 CMS reports the Hybrid Hospital-Wide Readmission measure (claims plus EHR data), which replaced the claims-only measure; values are close but not strictly comparable across the change. CMS suppressed it for 2026.. Latest available: 2025 release.
