Star Ratings Program

CMS Star Ratings

The Centers for Medicare & Medicaid Services (CMS) has developed Medicare Advantage plan quality measurements called Star Ratings.

CMS Star Ratings are used to rate qualify plan performance for:

  • Medicare Advantage (Part C), including special needs plans
  • Prescription drug plans (Part D)

Measures include:

  • Operational measures such as call center metrics, complaints, etc.
  • Healthcare Effectiveness Data and Information Set (HEDIS) measures
  • Consumer Assessment of Healthcare Providers and Systems (CAHPS) measures, such as customer satisfaction
  • Pharmacy measures

CMS Star Ratings are published annually on the CMS website to inform consumers about plan performance.

Care Provider Role in CMS Star Ratings

  • Many measures require complete, up-to-date encounter data.
  • Some measures track treatment of chronic conditions such as diabetes management, controlling blood pressure and medication adherence.

Please encourage your patients who are Medicare Advantage and prescription drug benefit plan members to have an annual physical or well visit to document body mass index (BMI), medications, vital signs and any changes in the member’s health status.
