Learn about the Medicare Advantage Open Enrollment Period with Medicare Helpline.

Medicare Advantage Open Enrollment Period (OEP)

The Medicare Advantage Open Enrollment Period is an additional opportunity for consumers on a Medicare Advantage plan to make a single plan change. OEP runs between January 1 and March 31 every year.

What can I change during the Medicare Advantage Open Enrollment Period?

The Medicare Advantage Open Enrollment Period is exclusively for those already on a Medicare Advantage Plan. If you qualify to make a change during the Medicare Open Enrollment Period, you can choose a different Advantage Plan or choose to return to Original Medicare. If you decide to discontinue the Advantage Plan, you can also enroll in a separate Prescription Drug Plan (Part D).

For those enrolled in a Medicare Advantage Plan, only one switch is allowed during the Medicare Advantage Open Enrollment Period in the first quarter of the year.

During this enrollment period, Original Medicare policyholders cannot:

  • Switch from Original Medicare to a Medicare Advantage plan
  • Join a Medicare Prescription Drug Plan (Part D)
  • Switch Medicare Prescription Drug Plans
