Initial Enrollment Period (IEP)

Each person who becomes eligible for Medicare will be granted an Initial Enrollment Period where they may enroll in Medicare for the very first time.

Your Medicare IEP typically begins three months before you turn 65 years old, include the month of your birthday and continue on for three additional months for a total of seven months.

Example: You turn 65 on June 5. Your Initial Enrollment Period starts on March 1 (3 full months before June) and ends September 30 (3 full months after June).

If you become eligible for Medicare before 65 due to a qualifying disability, you may be able to enroll in a Medicare Advantage plan after you have been getting Social Security or Railroad Retirement Board benefits for 24 full months.

After that point, you have 7 full months to enroll in a Medicare Advantage Plan. Your coverage will begin on your 25th month of receiving disability benefits.

If you have Amyotrophic Lateral Sclerosis (ALS), you are eligible for Medicare the first month you receive your disability benefits.

If you have End Stage Renal Disease (ESRD), you may also be able to enroll in Medicare Advantage plan if you qualify for Medicare because your kidneys no longer function, you need regular dialysis or have had a kidney transplant and if:

  • You worked for the amount of time required by Social Security, the Railroad Retirement Board (RRB) or as a government employee
  • You are already eligible for or already get Social Security or Railroad Retirement benefits
  • You’re the spouse or dependent child of a person who meets the above requirements

Fall Medicare Open Enrollment Period

The fall Medicare Open Enrollment Period is also sometimes called the Annual Enrollment Period (AEP).

The fall open enrollment period for Medicare occurs every year from October 15 to December 7.

During this time, beneficiaries can enroll in a Medicare Advantage plan, switch Medicare Advantage plans or drop a plan entirely to remain on Original Medicare (Medicare Part A and Part B).

Special Enrollment Period (SEP)

Depending on your circumstances, you may potentially qualify for a Medicare Special Enrollment Period (SEP) if you experience certain qualifying life events, including but not limited to:

  • Changing where you live
  • Losing your current Medicare Advantage plan through no fault of your own
  • Having your plan change its contract with Medicare

Call to speak with a licensed insurance agent who can help determine if you are eligible for a Special Enrollment Period.

How to enroll in a Medicare Advantage plan
