CMS’ Medicare Star Ratings

Each year, Medicare rates health and prescription drug plans on a Five–Star Quality Rating System. The Star ratings measure Medicare Advantage plans based on five areas:

• Staying healthy
• Managing chronic (long-term) conditions
• Member experience with the health plan
• Member complaints
• Health plan customer service

Stars for each plan show how well the plan performs in a particular category. Star ratings range from 1 star to 5 stars, where a rating of 1 star means “poor” quality, 2 stars means “below average” quality, 3 stars means “average” quality, 4 starts means “above average” quality and 5 stars means “excellent” quality.
