The Centers for Medicare & Medicaid Services (CMS) provides the star rating for Medicare plans based on information gathered through member surveys, health care providers, and plans. If a 5-star plan is available in your area, you may be able to switch plans during the 5-star Special Enrollment Period.
The 5-star Special Enrollment Period allows you to switch to a Medicare Advantage plan with a 5-star quality rating one time between December 8 and November 30.
