Enrollment Periods

Enrollment Timeframes

When can you join a Medicare Advantage plan?

There are specific times when you can sign up for Medicare Advantage plans, or make changes to coverage you already have. You don't need to sign up for Medicare each year. However, each year you'll have a chance to review your coverage and change plans.

When you first get Medicare (Initial Enrollment Periods for Part C & Part D)

  • You are newly eligible for Medicare because you turned 65.
    • You can sign up for a Medicare Advantage plan during the 7-month period that starts 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65. Your coverage will begin the first day of the month after you ask to join a plan. If you join during one of the 3 months before you turn 65, your coverage will begin the first day of the month you turn 65.
  • You are newly eligible for Medicare because you have a disability (under 65).
  • You are already eligible for Medicare because of a disability, and you turned 65.
  • You have Medicare Part A coverage, and enrolled in Medicare Part B during the Part B General Enrollment Period (January 1–March 31).
    • You can sign up for a Medicare Advantage plan between April 1-June 30.

During certain times each year (yearly enrollment periods for Part C & Part D)

Each year, you have a chance to make changes to your Medicare Advantage or Medicare prescription drug coverage for the following year. There are 2 separate enrollment periods each year.
