What do Medicare Star Ratings mean?
Medicare Star Ratings is a scoring system Medicare uses to rate the performance of all Medicare prescription drug and health plans. Star Ratings range from 1 to 5 stars with five being the highest score. Medicare established Star Ratings to help consumers readily evaluate how well Medicare Prescription Drug plans and Medicare Advantage plans perform when considering enrollment choices.
Plan performance is rated on several categories, including quality of care, customer service, accuracy, safety and more. Every plan is evaluated and their ratings are subject to change every year. Medicare issues new Star Ratings every fall—prior to the Annual Election Period (open enrollment)—so that beneficiaries can make coverage choices based on the most up-to-date performance ratings.
