Overall Star Rating

The Overall Star Rating combines each plan's scores for all the types of services they offer into a single summary score that makes it easy for you to compare plans based on quality and performance. Learn more about differences among plans by looking at the detailed ratings. What is being measured? For plans covering health services, the overall quality score is based on over 35 different topics. For example, plans are rated in how well they help you stay healthy as well as manage chronic (long-term) conditions. They are also rated according to results of satisfaction surveys of their members, tracking complaints filed by their members with Medicare, and monitoring of their customer service calls. For plans covering drug services, their overall quality is based on ratings in more than 12 different topics ranging from customer service of their call center and their appeals department to the accuracy of their prices on Medicare's website. They are also rated on the initiatives they take to improve the safety of prescription drugs. For plans covering both health and drug services, the overall score for quality of those services covers all of the topics described above.
