Understand the Medicare Initial Enrollment Period

Every Medicare beneficiary will have an IEP, or Initial Enrollment Period, during which they are eligible to enroll in Medicare. You can enroll in either Medicare Parts A and B or Medicare Advantage during this time. If you choose Parts A and B, you can also add on Part D (prescription drug coverage) and Medicare Supplements.

When is the Medicare Initial Enrollment Period (IEP)?

If you’re aging into the Medicare program (turning 65), your Medicare IEP will begin three months before you turn 65 and will end three months after. This gives you a total of  seven months to enroll. For example, if your birthday is April 1, your Medicare IEP will last from January 1 through August 1.

If you’re becoming eligible for Medicare based on another factor other than age, your IEP may be different. 

For example, if you are eligible for Medicare due to a diagnosis of either ESRD or ALS, you will be eligible to enroll following your diagnosis. If you start recieving disability benefits from Social Security, you will be automatically enrolled into the edicare program as soon as your benefits begin. 

If you become eligible for Medicare due to SSDI (Social Security Disability Income), you will be automatically enrolled in Medicare during your 25th month of receiving benefits.

If you qualify for Medicare and have an Initial Enrollment Period before you turn 65, you’ll have a second IEP when you do turn 65. This is called your “IEP2” and will start three months before your 65th birthday and end three months after.

When can I Apply for Medicare?

The Medicare Initial Enrollment Period is when most people are first able to apply for Medicare. If you miss your Initial Enrollment Period, you will need to enroll during the General Enrollment Period (Jan 1 through March 31).

Outside of the Medicare IEP and GEP, there are three other enrollment periods:

Free Prescription Discount Card

Late Enrollment Penalty Fee

In most cases, if you do not enroll during your Medicare Initial Enrollment Period, you will be charged a late enrollment penalty fee (added to your Part B premium). If you choose to delay coverage because you already have coverage under an employer, you can have your penalty fee waived.

When Will my Medicare Coverage Begin?

If you enroll within three months before your 65 birthday, your coverage will begin during your birthday month. If you wait until your birthday month or later, you may have to wait a few extra months for your coverage to become effective. If you miss your IEP and have to enroll during the General Enrollment Period in January, your coverage will most likely not begin until July. This, on top of the late enrollment fees, is why it is so important that you do not miss your Initial Enrollment Period!

How to Enroll in Medicare

Some people will be automatically enrolled in Original Medicare (Part A and Part B) and will not have to worry about enrolling during their Medicare Initial Enrollment Period. You may be automatically enrolled if you are turning 65 and are already getting either Social Security benefits or Railroad Retirement benefits. If you are automatically enrolled, you will receive a Medicare card about three months before your 65 birthday.

If you are not yet 65 but are receiving Social Security or Railroad Retirement Board disability benefits, you will be automatically enrolled in Medicare after about two years of receiving disability benefits. If you have ALS, you will be automatically enrolled in the same month that your disability benefits begin. If you have ESRD (end-stage renal disease), you can enroll any time even if you are not receiving disability benefits.

To begin your enrollment process, visit, call 1-800-772-1213 (TTY 1-800-325-0778), or visit your local Social Security office. Railroad Retirement beneficiaries can call 1-877-772-5772 (TTY 1-312-751-4701).

How to Enroll in Medicare Advantage

Have you read about what Original Medicare includes? Most people start by enrolling in Original Medicare through Social Security. However, a lot of people don’t realize that there are other options. Original Medicare only includes Part A (hospital coverage) and Part B (medical coverage). To get prescription drug coverage and avoid the late enrollment penalty fee, you’ll also need to enroll in either Part D or Medicare Advantage. Those plans are not offered by the government.

There are hundreds and hundreds of Part D and Medicare Advantage plans out there. The easiest way to enroll is by speaking with a licensed agent who knows about all or most of those plans and can help you pick the right one. Are you ready to get the coverage you deserve?
