If you want to join a 5-star Medicare Advantage or Medicare D plan or switch to one you can do it in this window. Medicare awards 1- to 5-star ratings to Medicare Advantage and Prescription Drug Plans based on member satisfaction surveys and information from the plans and healthcare providers. The highest 5-star rating is considered excellent.
You can switch into a 5-star Medicare Advantage Plan, Medicare Cost Plan, or Prescription Drug Plan (PDP) in your area outside of the Annual Enrollment Period (AEP) during all but one week of the year (December 1 to 7). Your coverage starts the first day of the following month.
You can't keep switching, though. You can use only one 5-star Special Enrollment Period per year.
