Enrollment Periods for a Medicare Advantage Plan

When can I join, switch, or drop a Medicare Advantage Plan?

  • When you first become eligible for Medicare, you can join during the 7-month period that begins 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65.
  • If you get Medicare due to a disability, you can join during the 7-month period that begins 3 months before your 25th month of disability and ends 3 months after your 25th month of disability.
  • Between October 15 and December 7 people who are eligible for Medicare can join, switch, or drop a Medicare Advantage Plan. Your coverage will begin on January 1, as long as the plan gets your enrollment request by December 7.

Can I make changes to my coverage after December 7?

Between January 1 and March 31, if you’re enrolled in a Medicare Advantage Plan, you can leave your plan and switch to another Medicare Advantage plan or Original Medicare. If you switch to Original Medicare during this period, you’ll have until March 31 to also join a Medicare Prescription Drug Plan (Part D) to add drug coverage. Your coverage will begin the first day of the month after the plan gets your enrollment request.

During this period, you cannot:

  • Switch from Original Medicare to a Medicare Advantage Plan.
  • Switch from one Medicare Prescription Drug Plan to another.
  • Join, switch, or drop a Medicare Medical Savings Account Plan.

Special Enrollment Periods

In most cases, you must stay enrolled for the calendar year starting the date your coverage begins. However, in certain situations, you may be able to join, switch, or drop a Medicare Advantage Plan during a Special Enrollment Period. Contact your plan if:

  • You move out of your plan’s service area.
  • You have Medicaid.
  • You qualify for Extra Help.
  • You live in an institution (like a nursing home).
