The 5-Star Enrollment Period 

The 5-star enrollment period for Medicare Advantage. This SEP lasts for nearly a year as it runs from December 8 to November 30 of the following year.

If a Medicare Advantage plan with a 5-star rating is available in your area, you can use the 5-star Special Enrollment Period (SEP) to switch from their current Medicare plan to a Medicare plan with a “5-star” quality rating.

Medicare uses information from member satisfaction surveys, plans, and health care providers to give overall performance star ratings to plans. A plan can get a rating between 1 and 5 stars. A 5-star rating is considered excellent.

CMS rates Medicare Advantage and Part D plans annually, using a scale from one to five, with more stars equating to better performance and quality. A five-star rating is the highest a Medicare Advantage or Part D plan can receive, and half-ratings also exist (1.5, 2.5, 3.5, 4.5).


Here’s what the star ratings mean:


  • 5-star rating: excellent performance
  • 4-star rating: above-average performance 
  • 3-star rating: average performance
  • 2-star rating: below-average performance
  • 1-star rating: poor performance


Medicare Advantage Trial Right Period

If you enroll in a Medicare Advantage plan during your Initial Coverage Election Period when you were first eligible for Medicare, Or you have dropped a Medicare Supplement policy to enroll in a Medicare Advantage Plan for the first time, you are entitled to a 12-month trial period. During this 12-month window, you have a Special Enrollment Period you can use at any time to cancel your Medicare Advantage plan and return to Original Medicare.
