What the rating means for you
- Medicare scores each contract on dozens of measures — staying healthy, managing chronic conditions, member experience, complaints, and customer service — then rolls them into the star rating.
- Medicare flags contracts that stay below 3 stars for three years; a low rating is a reason to look closely at alternatives in your area.
- Stars rate the whole contract, which may span many individual plans. Your specific plan's network, drug list, and costs matter just as much.
RECORDED — the star ratings, organization, parent, type, and SNP flag are CMS-published values (2026 Star Ratings). DERIVED — the percentile and the comparison to the national average.
