Key Takeaways
Medicare is a federal health insurance program, covering a wide range of services to keep you healthy as you get older
It's important to take the time to understand when you are required to make a decision.
Not enrolling on time during your Initial Enrollment Period could lead to a penalty.
There are several times to enroll in Medicare, and each of those times has its own rules around applying and when coverage will begin. Understanding when to enroll is an important part of avoiding coverage gaps and Medicare late enrollment penalties.
Initial Enrollment Period
The Initial Enrollment Period (IEP) is the first time to sign up for Medicare and join Parts A, B, C, and D. It happens:
- 3 months before your 65th birthday,
- Your birthday month, and
- 3 months after your 65th birthday.
When is My 7-Month Initial Enrollment Period?
Coverage will start no sooner than the month of your 65th birthday month, but you can enroll three months before your birthday.
Example: If your birthday is in July, your Initial Enrollment Period begins April 1 and ends October 31.
If you miss your enrollment period, you will have another chance to enroll but waiting could result in late penalties and a period without health coverage. Learn more about penalties for late enrollment.
Special Enrollment Period
There are Special Enrollment Periods (SEPs) that apply when eligible for delayed enrollment in Medicare Parts A, B, C, & D. These SEPs are only available for certain circumstances. Learn more about Medicare Special Enrollment Periods.

General Enrollment Period
If you miss the Initial Enrollment Period or Special Enrollment Period, there is another chance to enroll.
Sign up for Medicare Parts A & B can also happen between January 1 and March 31 each year. Medicare coverage would begin on July 1 of the same year. (Coverage gaps and late enrollment penalties can apply.)
It is important to note that if Part A is needed during this time, enrollment in Part B is required as well.

Open Enrollment Period
The Open Enrollment Period – sometimes called the Annual Election Period or Annual Coordinated Enrollment Period – runs each year from October 15 to December 7. During this time:
- Anyone with Original Medicare (Parts A & B) can switch to a Part C (Medicare Advantage) plan.
- Anyone with Medicare Part C/Medicare Advantage can switch back to Original Medicare (Parts A & B) and enroll in a Part D plan.
- Anyone who has Original Medicare (Parts A or B) can join, drop, or switch a Part D prescription drug plan.
- Anyone with Medicare Part C/Medicare Advantage can switch to a new Part C plan.
Coverage will start on January 1 of the following year.
