During designated Medicare enrollment periods, you have the opportunity to enroll in a Medicare plan, change your current plan, or drop a plan altogether.
Understanding these periods is essential for both new and existing Medicare enrollees, as they help you avoid late enrollment penalties and ensure you maintain continuous coverage.
| Initial Enrollment Period (IEP) | General Enrollment Period (GEP) | Special Enrollment Period (SEP) | Annual Enrollment Period (AEP) | Open Enrollment Period (OEP) | |
|---|---|---|---|---|---|
| Who Needs | Turning 65 | Missed IEP | Various Special Circumstances* | Medicare Plan Enrollees | Medicare Advantage |
| Purpose | Enroll in Original Medicare | Enroll in Medicare Part A or Part B | Enroll in Medicare Part A or Part B | Reevaluate coverage & Make Changes | One-time change to MA Plan |
| When | 3 months before 65th birthday through 3 months after | January 1 - March 31 | Varies by Circumstances | October 15 - December 7 | January 1 - March 31 |
The Initial Enrollment Period (IEP) is your first opportunity to enroll in Medicare. It begins three months before your 65th birthday and lasts for a total of seven months, ending three months after you turn 65.
During this time, you can sign up for Medicare Part A and Part B (Original Medicare). If you're receiving Social Security Disability benefits or qualify for automatic enrollment, you may not need to enroll manually.
However, if you are not automatically enrolled and don't sign up during this period, you could face permanent late enrollment penalties, especially if you don't have creditable coverage in place.
The General Enrollment Period (GEP) is the second opportunity to enroll in Medicare if you missed your IEP or delayed signing up. The GEP takes place each year from January 1 to March 31.
If you enroll during this time, your Medicare coverage will not begin until July 1, potentially leaving you with a coverage gap. If you don't qualify for a Special Enrollment Period, the GEP may be your only chance to enroll in Original Medicare outside of your IEP.
Keep in mind that enrolling during the GEP usually means you'll face a late enrollment penalty, which could result in higher premiums.
The Medigap Open Enrollment Period allows you to enroll in a Medicare Supplement (Medigap) plan once you are enrolled in Original Medicare and are 65 or older. This period gives you a six-month guaranteed issue right to sign up for a Medigap plan without the risk of being denied coverage or facing higher premiums due to your medical history.
However, if you miss this window, insurers may have the right to deny coverage or charge higher rates based on your health condition.
The Medicare Annual Enrollment Period (AEP) runs from October 15 to December 7 each year. During this time, current Medicare enrollees can make important changes to their coverage, such as:
This period gives you the flexibility to adjust your Medicare coverage based on your evolving healthcare needs.
The Special Enrollment Period (SEP) allows you to enroll in Medicare without facing late enrollment penalties if you delayed your initial enrollment due to certain qualifying circumstances. For instance, you may qualify for an SEP if you had creditable coverage during your initial enrollment period but have since lost that coverage.
