Medicare Advantage Special Enrollment Period

If you received a letter from your Medicare Advantage (MA) plan stating that it will no longer sell its plan in your area, you have a special enrollment from Dec. 8 to Feb. 28. You have the option to:

The new plan starts depending on when you enroll. To ensure coverage starts Jan. 1, you should enroll before Dec. 31. If you do nothing before Feb. 28, 2025, you’ll automatically be covered by Original Medicare Parts A and B only. But you must act if you want to continue to have prescription drug coverage, either by enrolling in an MA plan that includes drug coverage or by enrolling in a Medicare Part D prescription drug plan.  

Medicare Advantage Open Enrollment Period

Jan. 1 – March 31 is the Medicare Advantage Open Enrollment Period (MA-OEP). You must be enrolled in an MA plan on Jan. 1 to make a switch. Any changes you make take effect on the first day of the month after your request.
