What Is a Good Hospital Rating? Understanding 1 to 5 Stars
When researching hospitals, you'll encounter star ratings that range from 1 to 5. But what constitutes a "good" rating, and how should you interpret these numbers? This guide helps you understand hospital ratings and use them wisely in your healthcare decisions.
Understanding the Star Rating Scale
CMS (Centers for Medicare & Medicaid Services) assigns overall quality ratings to hospitals based on data across multiple performance categories:
- 5 stars: Performance significantly above the national average — approximately 10-15% of rated hospitals achieve this
- 4 stars: Above average performance — roughly 20-25% of rated hospitals
- 3 stars: Average performance — the largest group, about 25-30% of rated hospitals
- 2 stars: Below average performance — approximately 20-25% of rated hospitals
- 1 star: Significantly below the national average — about 5-10% of rated hospitals
Is 3 Stars "Bad"?
A 3-star rating means a hospital performs at roughly the national average. This does not mean the hospital provides poor care. Many well-known, reputable hospitals receive 3-star overall ratings because:
- They may serve more complex, higher-acuity patients
- They may excel in certain specialties while scoring lower in others
- Teaching hospitals often score differently due to their training mission
- The rating averages across all categories, masking individual strengths
Why a 5-Star Hospital Isn't Always Your Best Choice
The highest-rated hospital may not always be the right hospital for your situation:
- Specialty matters: A 3-star hospital with an excellent cardiac program may be better for heart surgery than a 5-star hospital without one
- Distance and access: A closer hospital with good ratings may be preferable to a distant 5-star facility
- Your doctor: Your physician's privileges and experience at a specific hospital matter significantly
- Insurance network: Out-of-network care at a higher-rated hospital could result in substantial costs
Looking Beyond the Overall Rating
For the most meaningful comparison, examine the individual categories that matter for your specific needs:
- For surgery: Focus on mortality rates, safety of care, and infection rates for your procedure
- For chronic conditions: Look at readmission rates and effectiveness of care
- For emergency care: Check timeliness of care and emergency department metrics
- For comfort: Review patient experience (HCAHPS) scores

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.
