Enrollment Periods

There are four enrollment periods for Blue Cross MedicareRx. Review them to find which one is right for you.

Annual Enrollment Period (AEP)

Anyone can join, switch or drop a Medicare prescription drug plan between October 15 and December 7. If you apply during this time, coverage begins on January 1.

Open Enrollment Period (OEP)

Medicare Advantage enrollees using the Medicare Advantage Open Enrollment Period (MA OEP) have a Special Election Period (SEP) to add or change Part D coverage. The MA OEP is available from January 1 through March 31 each year. It is also available for the first three months an individual has Medicare eligibility. The SEP is a onetime election to allow individuals enrolled in either a MAPD or Medicare Advantage only plan to switch to a MAPD, Medicare Advantage only or back to the Original Medicare with a stand-alone Part D Plan.

A Medicare Advantage eligible individual who elects Original Medicare during MA OEP may elect to enroll in a Prescription Drug plan during this time. The effective date for a MA OEP election is the first of the first of the month following receipt of the enrollment request.

Initial Enrollment Period (IEP)

When you are first 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.

Special Enrollment Period (SEP)

In most cases, you must stay enrolled for the calendar year when your coverage began. You may be able to join, switch or drop a Medicare prescription drug plan during a Special Enrollment Period. Here are some, but not all, of the ways that bring about a Special Enrollment Period:

  • Moving outside of the plan's approved service area
  • Entering or leaving a qualified institution, such as a nursing home
  • Becoming eligible for low-income subsidy assistance
  • Becoming enrolled in Medicaid
  • Leaving or losing your employer's health plan

Contact your plan if any of these situations apply to you. For more information, refer to the Medicare and You Handbook.

*Dates subject to change after January 1, 2022.
