US News Hospital Rankings vs CMS Stars: What's the Difference?
Two of the most prominent hospital rating systems in the United States are the U.S. News & World Report Best Hospitals rankings and the CMS (Centers for Medicare & Medicaid Services) star ratings. While both aim to help patients find quality care, they use different methodologies and measure different things.
CMS Star Ratings Overview
CMS star ratings are produced by the federal government and appear on the official Medicare Care Compare website:
- Scale: 1 to 5 stars
- Data source: Publicly reported quality measures submitted by hospitals to CMS
- Scope: Rates nearly all Medicare-certified hospitals (approximately 4,500+)
- Categories: Mortality, safety, readmission, patient experience, and timely/effective care
- Cost: Free to access, no paywall
- Update frequency: Annually
- Methodology: Statistical clustering of quality measures across all categories
U.S. News & World Report Rankings Overview
U.S. News rankings are produced by a private media company and published annually:
- Scale: Ranked list by specialty (Best Hospitals for Cardiology, Orthopedics, etc.)
- Data source: Federal data, reputation surveys of physicians, and hospital-reported data
- Scope: Evaluates roughly 5,000 hospitals but only ranks the top performers in each specialty
- Categories: 15 adult specialties and 10 pediatric specialties
- Cost: Some content behind a paywall
- Update frequency: Annually (typically summer)
- Methodology: Combines clinical outcomes, physician survey responses, and patient experience
Key Differences
Purpose
- CMS: Provides a broad overall quality snapshot for all hospitals
- U.S. News: Identifies top performers in specific medical specialties
Reputation Component
- CMS: Does not include reputation surveys — relies entirely on measurable data
- U.S. News: Includes physician reputation surveys, which can favor large, well-known academic medical centers
Coverage
- CMS: Rates the vast majority of hospitals
- U.S. News: Many hospitals are evaluated but only top performers appear in ranked lists
Which Should You Use?
- For general quality comparison: Start with CMS star ratings for a broad, data-driven view
- For specific procedures or specialties: U.S. News rankings can help identify top specialty programs
- For comprehensive research: Use both systems together for the most complete picture
- Remember: Neither system captures everything about a hospital's quality, and both should be supplemented with input from your physician
Other Rating Systems
Additional resources for hospital quality information include:
- Leapfrog Hospital Safety Grade: Focus on patient safety (A through F grades)
- Joint Commission accreditation: Indicates the hospital meets national quality standards
- State health department reports: Inspection results and compliance data

Important
This article explains how hospital quality data works and is for general information only. It is not medical advice and must not be used to decide whether to seek, delay or refuse care — that is a decision for you and a clinician who knows your situation.
CMS quality measures describe care delivered during earlier reporting periods and are refreshed roughly quarterly. A hospital's staffing, services and performance can change well before the published numbers do.
