Answer:

You can enroll in Medicare Advantage when you first become eligible for Medicare and then at certain times during the year as long as you are enrolled in Medicare Parts A and B.[1][2]

You can generally enroll in Medicare Advantage during the following periods:

Initial Enrollment Period: You can enroll in a Medicare Advantage plan any time during the seven month period surrounding and including the month you first become eligible for Medicare.

Part B Special Enrollment Period: You can enroll in Medicare Advantage during this period if you qualify for Part B Special enrollment.

Jan 1 – Mar 31 (General Enrollment): If you enrolled in a Medicare Advantage plan, you can switch to a different Advantage plan or switch back to Original Medicare (and join a Standalone drug plan if you wish). This period is also called the “Medicare Advantage Open Enrollment Period.”

April 1 – June 30 (Limited Enrollment for Part C and Part D): You can enroll during this period if you signed up for Parts A and B during general enrollment.

Oct 15 – Dec 7 (Open Enrollment): You can pick a new Medicare Advantage Plan or switch between Original Medicare and Medicare Advantage.
