What Is the Star Ratings System?
The Star Ratings System evaluates the quality of care beneficiaries receive from Medicare Advantage and Part D plans on a 1 to 5 scale based on performance on more than 40 individual measures. The system was originally developed to help beneficiaries choose between available plans.
Medicare Advantage plans with higher Star Ratings of at least 4 stars receive increased funding as an incentive to achieve high performance. Plans use these funds to provide additional benefits and reduce beneficiary cost-sharing.
