Medicare Star Quality Ratings

Medicare Star Quality Ratings for Medicare Advantage plans measure overall health plan performance. This program evaluates Medicare health and prescription drug plans. It is administered by the Centers for Medicare & Medicaid Services (CMS), the federal agency that oversees Medicare.

Based on CMS findings, each plan is assigned a rating between 1 and 5 Stars.
