As you’re comparing Medicare Advantage plans based on their benefits, you may also want information on how they are evaluated. Medicare Star Ratings, which are determined 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.

What are Medicare Star Ratings?

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:

  • Satisfaction surveys from members enrolled in the plan
  • Information from the plan itself – for example, how many members have disenrolled since the prior year
  • Reports from healthcare providers – for instance, how many members have received important health screenings and appropriate care

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.”

Medical Mutual’s commitment to customer care has been reflected in our Medicare Star Ratings. For 2021, our Medicare Advantage PPO plans have earned Medicare’s highest rating – 5 out of 5 Stars for 2022. Our HMO plans are also highly rated, earning 4.5 out of 5 Stars.
