Understanding Medicare Enrollment Periods

Each year there are set times a person can enroll in Medicare or change existing Medicare plans. There are separate enrollment periods for Medicare Parts A and B (Original Medicare) and Medicare Part C (Medicare Advantage).

Medicare Enrollment Periods

  • Initial Enrollment Period (IEP) – the first time an eligible person can enroll in Medicare Parts A and B. This timeline begins three months before the month of a person’s 65th birthday and continues through the three months after a person’s 65th birthday.
  • Initial Coverage Election Period (ICEP) – the first time a newly eligible person can enroll in a Medicare Advantage plan. This often coincides with the Initial Enrollment Period.
  • General Enrollment Period (GEP) – runs January 1 – March 31 each year and provides an enrollment opportunity for individuals who didn’t sign up for Original Medicare (Part A and Part B) when they were first eligible. Individuals may have to pay a late enrollment penalty for not enrolling when first eligible and coverage will not start until July 1 of that year.
  • Annual Enrollment Period for Medicare Advantage and Prescription Drug Plan (AEP) – current Medicare recipients can change or enroll in Medicare Advantage coverage during this period that runs October 15 through December 7.
  • Special Enrollment Period (SEP) – certain life events can lead to an individual being eligible for enrolling in Original Medicare or enrolling in or changing Medicare Advantage coverage.

Opportunities for a Medicare Advantage Special Enrollment Period Include:

●      Moving to a new location where new plan options are available
●      Losing employer coverage
●      Being diagnosed with a qualifying chronic condition, such as diabetes or chronic heart failure
●      Moving in or out of a skilled nursing facility or long-term care hospital

Medicare Advantage Open Enrollment Period (OEP)

The Medicare Advantage Open Enrollment Period (OEP) runs from January 1 through March 31 and is new in 2019. Beneficiaries in a Medicare Advantage only or Medicare Advantage Prescription Drug plan as of January 1 can make a one-time change to:

  • Switch to a different Medicare Advantage Plan
  • Drop Medicare Advantage and return to Original Medicare (Part A and Part B)
  • Sign up for a stand-alone Medicare Part D Prescription Drug plan, if an individual elects to return to an Original Medicare plan

The Medicare Advantage OEP is only accessible for current Medicare Advantage policyholders. During Medicare Advantage OEP, 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
