Medicare Advantage Open Enrollment Period

In addition to Medicare’s Annual Open Enrollment Period, you can take advantage of a separate Medicare Advantage Open Enrollment Period from January 1 through March 31. Unlike the Medicare Annual Open Enrollment Period, this enrollment period is only for people who are currently enrolled in a Medicare Advantage plan and wish to make changes.

During this open enrollment period, if you already have a Medicare Advantage Plan you can do the following:

  • Switch to another Medicare Advantage Plan, or
  • Cancel your current Medicare Advantage Plan and return to Original Medicare. In this scenario, you will also be able to join a Medicare Part D Plan.

Also keep in mind that If you enrolled in a Medicare Advantage Plan during your Initial Enrollment Period, which is the sign up period when you first become eligible for Original Medicare, you can change to another Medicare Advantage Plan or go back to Original Medicare within the first 3 months that you have coverage.

Note: Each year, insurance companies can make changes to Medicare plans, including changes to the prescription drugs they cover.  It is a good idea to review your current Medicare plan every year to make sure it still meets your needs.
