Medicare uses a five-star rating system to evaluate Medicare Advantage plans. Medicare star ratings can change from one year to the next. Learn how to compare star ratings for the Medicare Advantage plans offered in your area.
All Medicare Advantage plans (Medicare Part C) and Medicare prescription drug plans (Medicare Part D) are assigned an annual star rating by the Centers for Medicare & Medicaid Services (CMS).
A five-star rating system is used, with one star being given to the lowest-rated plans, and five stars being reserved for only the highest-rated plans. Star Ratings are calculated each year and may change from one year to the next.
Five-star Medicare Advantage plans may not be available where you live. You can use the Medicare star ratings to help you compare the plans that are available in your area.
In 2024, roughly 74 percent of beneficiaries in Medicare Advantage plans that offer prescription drug coverage are enrolled in a plan rated 4 stars or higher by Medicare, when weighted by enrollment. 1

TTY 711, 24/7Medicare determines which Medicare Advantage plans are highest rated based on information gathered from health care providers who accept the plan, plan member satisfaction surveys, positive health outcomes, customer service and more.
A 5-star plan is considered a highest-rated plan. 1-star plans are the lowest-rated plans, and these plans typically earn their low rating due to poor plan performance, low customer satisfaction and/or bad customer service.
The star rating system for Medicare Advantage plans is as follows:
Star Ratings
The rating system uses five key metrics in its assessment of a Medicare Advantage plan:
In addition to an overall rating, each Medicare Advantage plan is rated in each of the five individual categories. Medicare Star Ratings are released in October of each year for the upcoming calendar year.
If a plan receives a rating of fewer than three stars for three consecutive years, it becomes flagged by the CMS as a low-performing plan. If the plan continues to underperform, Medicare may remove the plan entirely from the marketplace.

TTY 711, 24/7 Continue onlineBecause the availability of Medicare Advantage plans varies from one location to the next, you may want to call to speak with a licensed insurance agent. A licensed sales agent can go over the plan options available in your area and identify if any have a five-star rating.
An agent can also discuss the costs, terms, coverage and other details about available plans, which can be helpful for you to know prior to enrolling. And if you choose to enroll, you’re eligible to enroll and you have a qualifying enrollment period, the agent can walk you through the steps and help you complete the process.
If you are enrolled in a Medicare Advantage plan rated lower than five stars but you find a five-star plan in your area, you may be able to switch to the five-star plan at any time between December 8 and November 30 of the following year. This is called the five-star Special Enrollment Period.

There are certain Medicare enrollment periods during which eligible Medicare beneficiaries may enroll in a Medicare Advantage plan.
You can sign up for a five-star plan (if you’re eligible, have a qualifying enrollment period and find a five-star plan in your area) when you first become eligible for Medicare Advantage. Your eligibility begins once you are enrolled in both Medicare Part A and Part B.
When you reach Medicare eligibility, you are typically given a 7-month Medicare Initial Enrollment Period. This period begins three months before you turn 65 years old, includes the month of your birthday and continues for three months thereafter.
If you are already enrolled in Part A and/or Part B, you may sign up for a Medicare Advantage plan during the fall Medicare Open Enrollment Period (also sometimes called the Medicare Advantage Annual Enrollment Period), which lasts from October 15 to December 7 each year.
If you are already enrolled in a Medicare Advantage plan, you may use this time to switch to a different Medicare Advantage plan or drop your plan to remain on Original Medicare.

As mentioned above, this period lasts from December 8 to November 30 of the following year. During this period, you can only switch to a five-star plan.
