Medicare Initial Enrollment Period (IEP)

What is the Medicare Initial Enrollment Period (IEP)?

The Initial Enrollment Period (IEP) is a 7-month window surrounding your 65th birthday. This period includes the three months before you turn 65, the month you turn 65, and the three months after. During this time, you can sign up for:

  1. Original Medicare (Part A and Part B)
  2. Medicare Advantage Plans (Part C)
  3. Medicare Prescription Drug Plans (Part D)
  4. Medicare Supplement Plans (Medigap)

For individuals with ESRD or ALS, you may enroll immediately after your diagnosis. If you begin receiving SSDI, Medicare enrollment happens automatically once your benefits begin. Those who qualify for Medicare due to a disability will be automatically enrolled in their 25th month of receiving SSDI benefits.

How to Enroll in Part A and Part B

If you are nearing 65, or already 65, you can enroll in Medicare Part A and/or Part B through Social Security’s website. If you’re already receiving Social Security or RRB benefits, you'll be automatically enrolled in both Parts A and B.

  1. Cost:Part A is generally premium-free if you have 40 quarters (10 years) of work history. However, you will pay a monthly premium for Part B.
  2. How to Enroll:You can apply online through the Social Security website, by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778), or by visiting your local Social Security office. Railroad workers can contact the RRB at 1-877-772-5772 (TTY 1-312-751-4701).

Enrolling in Medicare Advantage (Part C) and Prescription Drug Plans (Part D)

  1. Part C (Medicare Advantage):Your Initial Coverage Election Period (ICEP) aligns with your IEP if you sign up for Medicare Part B during the same timeframe. If you delay enrolling in Part B, your ICEP occurs during the three months before your Part B coverage begins.
    To be eligible for a Medicare Advantage plan, you must already have Part A and Part B coverage. You can also enroll during the Annual Election Period (AEP) or when you qualify for a Special Enrollment Period (SEP).
  2. Part D (Prescription Drug Coverage):Like Medicare Advantage, you can sign up for Part D during your IEP. If you're under 65 and qualify for Medicare due to a disability, your IEP for Part D starts three months before and ends three months after the 25th month of receiving SSDI or RRB benefits.

When Does Medicare Coverage Begin?

Coverage start dates depend on when you enroll:

  1. During the first three months of your IEP:Your coverage starts on the first day of the month you turn 65.
  2. During your birth month or later in your IEP:Your coverage may begin one month or later after you enroll.
  3. If you miss your IEP: If you enroll during the General Enrollment Period (GEP), which runs from January 1 to March 31 each year, your coverage starts on July 1.

Medicare Creditable Coverage

Creditable coverage refers to health insurance that is expected to pay as much as Medicare's standard prescription drug coverage. Providers must notify beneficiaries annually by October 15, or when there is a change in creditable coverage status. This ensures that individuals who have other forms of drug coverage, such as through a group health plan, can avoid higher late enrollment penalties if they enroll in a Medicare Part D plan later.

Missed Your Initial Enrollment Period?

If you miss your IEP, you may still have options for enrolling in Medicare:

  1. General Enrollment Period (GEP): If you didn’t sign up during your IEP, you can enroll from January 1 to March 31 annually, with coverage beginning July 1. Late enrollment penalties may apply.
  2. Special Enrollment Period (SEP): SEPs are triggered by specific life events, such as losing employer coverage, moving to a new area, or becoming eligible for Medicaid. If you’re still working and covered by an employer plan during your IEP, you’ll have an 8-month SEP after your employment or coverage ends to enroll without a penalty.

Other Enrollment Periods

  1. Annual Enrollment Period (AEP): IFrom October 15 to December 7 each year, you can make changes to your Medicare coverage. During AEP, you can switch between Medicare Advantage and Original Medicare, change Medicare Advantage or Part D plans, or add/drop Medicare Part D coverage. Changes take effect on January 1 of the following year.
  2. Medicare Advantage Open Enrollment Period (OEP): From January 1 to March 31, those already enrolled in a Medicare Advantage plan can make a one-time change to another Medicare Advantage plan or return to Original Medicare (with or without Part D).
  3. Medigap Open Enrollment Period: Your six-month Medigap Open Enrollment Period begins when you first enroll in Medicare Part B. During this time, you can buy any Medigap policy available in your state without being denied due to pre-existing conditions. Outside of this period, insurers can require medical underwriting, meaning they could deny coverage or charge higher premiums based on your health status.

Other Enrollment Periods

Medicare Savings Programs can help cover Medicare costs like premiums, copayments, and deductibles for individuals who meet certain income and asset limits. There are three primary MSPs:

  1. Qualified Medicare Beneficiary (QMB) Program
  2. Specified Low-Income Medicare Beneficiary (SLMB) Program
  3. Qualified Individual (QI) Program

Additionally, if you qualify for any of these programs, you are automatically eligible for Extra Help, which assists with Medicare Part D costs.

Dual Eligibility

Individuals who qualify for both Medicare and Medicaid, known as dual-eligibles, may receive additional assistance with Medicare costs. Medicaid can cover expenses like premiums, copays, and deductibles, and individuals may also be eligible for Extra Help with prescription drug coverage.
