One of Medicare’s most important goals is to make the quality of Medicare advantage plans transparent. In this effort, Medicare advantage plans are each year rated on a scale ranging from 1 to 5 stars. While a 5-star rating is considered excellent, a one-star rating represents poor performance. The overall score makes it easy for Medicare beneficiaries to compare plans, based on quality and past performance.
Medicare Advantage Plan Ratings are published each year in fall, before the open enrollment period begins, and beneficiaries may enroll in or switch plans.
How are 5-Star ratings for advantage plans in 2025 determined?
For 2025, Medicare uses different quality signals for MA-PDs (Medicare advantage plans that include prescription drug coverage) and stand-alone PDP contracts.
The criteria for Medicare Advantage plans (also referred to as ‘Medicare Part C’) include, but are not limited to the following topics:
The criteria for MA-PDs covers these topics:
You can find the official list with high and low performing Medicare Advantage Plans, published by CMS.gov here.
Medicare beneficiaries may enroll in, or switch between 5-Star rated advantage plans at any time during the year, provided they meet the requirements of the plan (having Medicare Part A and B, living within the plan’s service area, even with a pre-existing condition).
Attention: If you switch from MA-PD (an advantage plan that includes drug coverage) to a plan that doesn’t, you will have to wait until the next open enrollment period (Oct 15-Dec 7 each year) to enroll in a drug coverage plan, and you may have to pay a late enrollment penalty!
