Enrollment Periods

Initial Enrollment Period (IEP), three months before and after you turn 65

For those who have never been eligible for Medicare, you will be able to enroll during the Initial Enrollment Period, which opens three months before you turn 65 and ends three months afterwards.  This Initial Enrollment Period is where you choose which plan you want to start with.

General Enrollment Period (GEP), January 1 – March 31

Anyone who missed their Initial Enrollment Period may enroll in Medicare Parts A and B.


Open Enrollment Period (OEP), January 1 – March 31

Medicare Advantage beneficiaries may change their plans during the Open Enrollment Period, or switch to Original Medicare.

Annual Enrollment Period (AEP), October 15 – December 7

The Annual Enrollment Period takes place each year from October 15 to December 7. This is the period where if you are already enrolled in Medicare you can make changes to your Medicare plan coverage.

Changes you may make during AEP include the following:

  • Switch from Original Medicare to an Advantage plan or vice versa.
  • Switch to an Advantage Plan where you choose whether to have prescription drug coverage or not.
  • Change from one Advantage plan to another.
  • Join, switch or leave a Medicare Part D prescription drug plan.
  • Switch to a private insurer.


Considerations during AEP:

  • Out of pockets costs: When making your Medicare decisions, consider costs of premiums, deductibles, copayments, and any other payments not covered by Medicare.
  • Prescription drug coverage: Check to see which drugs your plan covers, especially the drugs you currently use or may use in the future.
  • Health care needs: Consider whether upcoming or expected surgeries are covered and whether you would need to switch providers with the plan you choose.
  • Travel plans : Remember that Original Medicare does not typically cover overseas health care costs, so if you plan to travel overseas you may consider enrolling in a supplemental insurance plan.

Special Enrollment Period (SEP), depending on eligibility

Beneficiaries may change their Medicare coverage if they experience a qualifying event.
