You must wait for a suitable Medicare Advantage enrollment period to enroll in a Part C plan. An election period is the narrow window of opportunity you have a chance to enroll in, get out of, or change your Medicare Advantage plan.

Medicare Advantage Enrollment Periods

There are three windows of opportunity to enroll in a Medicare Advantage plan.

  1. Initial Coverage Election Period
  2. Annual Election Period
  3. Medicare Advantage Open Enrollment Period

Your Initial Coverage Election Period

Your Initial Coverage Election Period happens when you first become eligible for Original Medicare. It starts three months before your 65th birthday, includes the month you turn 65, and ends three months after that. This election period can also happen after receiving Social Security benefits for 24 months minimum.

The window of opportunity is the same seven months, but instead of revolving around your birth month, the month of your official eligibility is in the center.

The Annual Election Period

If your Initial Coverage Election Period has come and gone, another enrollment period to make changes in the Annual Election Period. For all qualifying beneficiaries, the AEP starts October 15 and lasts through December 7. Your benefits will kick in on January 1 of the following year.

The Medicare Advantage Open Enrollment Period

If you change your mind about Medicare Advantage, you’ll have to wait for The Medicare Advantage Open Enrollment Period, which occurs each year between January 1 and March 31.

During this window, you can switch to Original Medicare and enroll in a Medicare Part D prescription drug plan. You can also switch to Medicare Advantage from Original Medicare if you prefer.

Special Election Periods

Unless you qualify for a Special Election Period, you can’t enroll in Medicare Advantage outside one of the three above enrollment windows. There are certain qualifying life events that you must experience to get approved for this SEP. Some of those include (but are certainly not limited to):

  • Losing Medicaid eligibility
  • Becoming eligible for Medicaid
  • Moving into an institution
  • Qualifying for the Extra Help prescription drug program
  • Moving to a new zip code that your Medicare Advantage Plan does not service
