When Can I Enroll in a Medicare Advantage Plan?

medicare-advantage-enrollment-times

Enrollment for Medicare Advantage Plans isn’t open year-round, but you do have a number of opportunities to enroll in a plan of your choice or change plans.

To enroll in a Medicare Advantage Plan, you must already be enrolled in Medicare Parts A and B. All of these enrollment periods apply only if that requirement is met. (Learn more about enrolling in Original Medicare.)

Around Your 65th Birthday

You have a seven-month Initial Enrollment Period when you turn 65. It includes the three months before your birthday, your birthday month, and the three months after your birthday. You can enroll in a Medicare Advantage Plan at any time during your seven-month Initial Enrollment Period.

Learn more about Medicare and turning 65.

From October 15 to December 7

The Medicare Advantage Annual Enrollment Period occurs from October 15 to December 7 each year and offers the opportunity to enroll in or change Medicare Advantage Plans.

From January 1 to March 31

The Medicare Advantage Open Enrollment Period occurs during the first three months of the year and allows you to change Medicare Advantage Plans one time. This enrollment period is only open to you if you’re already enrolled in a Medicare Advantage Plan and want to enroll in a different plan.

During Special Enrollment Periods

There are a number of special circumstances that trigger Special Enrollment Periods (SEPs) during which you could enroll in a Medicare Advantage Plan. Special circumstances include:

  • You move to a new location
  • You lose your current coverage
  • You have an opportunity to get different coverage
  • There are changes in your current provider’s Medicare contract
  • You qualify for Extra Help
  • New Five-Star plan(s) becomes available
  • You qualify for dual-eligibility by having both Medicare and Medicaid
  • You’re eligible for a Medicare Special Needs Plan (SNP)

Special Enrollment Periods are not all the same length. Depending on your special circumstance, they can vary from one to three months long.

After Enrolling in Medicare Part B

If you don’t enroll in Medicare Parts A and B at the same time, and enroll in Part B during Medicare General Enrollment from January through March, you may have an opportunity to enroll in a Medicare Advantage Plan after you‘ve enrolled in Part B.
