If you’re shopping for a Medicare Advantage plan, you’re likely comparing plans based on their benefits and costs, but you may also want information on their quality. At the end of the day, we all want the best coverage and quality of care possible for our money. Medicare Star ratings, which are awarded by the Centers for Medicare & Medicaid Services (CMS), allow you to compare Medicare Advantage plans and Medicare Part D prescription drug plans based on many factors, including customer service, member satisfaction and quality of care.

How Medicare Star Ratings Work

Every year, CMS evaluates Medicare Advantage plans based on a 5-Star rating system. These ratings measure the quality of services people enrolled in Medicare Advantage receive from their plans. 

A plan’s rating takes into account a variety of sources:

  • Surveys of members enrolled in the plan – for example, how happy the members are with their plan
  • Information from the plan itself – for example, how many members chose to leave their plan
  • Third-party CMS contractors collecting additional data – for instance, a hospital reports how many members received important health screenings and appropriate care
  • Administrative data from CMS – includes regular monitoring activities on the plan’s performance

These details are combined to come up with the plan’s overall rating, which can range from 1 to 5 Stars. A rating of 5 Stars is considered “excellent.”

How to Use Medicare Star Ratings When Looking for a Plan

Overall, it’s best to choose the highest rated plan you can afford as plans with low Star ratings are generally associated with poor health outcomes. The great news is that many of the 5-Star Medicare Advantage plans are actually affordable and start as low as $0 per month. You can view all plans available in your area and compare their ratings by visiting the Plan Finder on Medicare.gov.

You can secure your Medicare coverage for January 2023 by joining MedMutual Advantage 5-Star HMO or PPO plan during the Annual Enrollment Period, whichruns through December 7, 2022.
