Medicare’s Initial Enrollment Period Explained

Learn when to enroll in Medicare to get the most of your coverage and avoid penalties
Print Friendly, PDF & Email

It is important to know how the dates work when enrolling in Medicare to get the most out of it. Initial enrollment in Original Medicare, Part A or Part B, usually happens automatically if you are about to turn 65 and already receiving Social Security or Railroad Retirement Benefits benefits. If not, you will need to sign up for Medicare Part A and/or Part B during the Initial Open Enrollment.

When does Medicare’s Initial Enrollment Period (IEP) begin?

IEP begins 3 months before the month of your 65th birthday and ends three months after the month of your birthday, lasting a total of 7 months, including the month of your birthday. You can use our Medicare Deadline Calculator to determine your IEP window and other important deadlines.

Initial Enrollment for Medicare is also Initial Enrollment for Medigap, MA and Part D drugs.

The periods are slightly different though:

    • Once you enroll in Medicare Part A and B you get a 6-month-period in which you can enroll in a Medigap Plan that covers the 20% that Medicare doesn’t and pays for your deductibles, copays and coinsurance.
    • The Initial Enrollment Period for Medicare Advantage and Part D Drug Plan is the same as for Medicare. Meaning you have the three months before your birthday, the month of your birthday, and then three more months.

What if I missed Medicare’s Initial Open Enrollment Period?

Keep in mind that if you do not sign up for Medicare Part B when you are first eligible and instead do it later, you may have to pay a late enrollment penalty. You can read all about it in our article What if I missed my Medicare Deadline? If you delay your Medicare Part B enrollment because of current work coverage (either your own or your spouse’s), you can qualify for a Special Enrollment Period at the ending of this coverage and you will not be subject to any penalties.
