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.
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.
