Medicare has five key enrollment periods: Initial (7 months around age 65), Medigap Open (6 months after Part B starts), Special (for life changes), General (Jan 1–Mar 31), and Annual (Oct 15–Dec 7). Our North Carolina agents help you navigate them to avoid penalties and secure the right coverage.
Navigating Medicare enrollment periods can feel overwhelming, but knowing the key ones helps you secure the right coverage without penalties. There are five main enrollment periods to understand:
Initial Enrollment Period (IEP): Your primary window to enroll in Medicare without penalties. This 7-month period starts 3 months before your 65th birthday month, includes your birthday month, and ends 3 months after.
Example: If you turn 65 in April, your IEP is January 1–July 31.
Enroll during this time for Parts A, B, C (Medicare Advantage), and D (prescription drugs) to start coverage the month you turn 65 (or the next month if enrolled later in the period).
If you miss it and lack creditable coverage, you may face lifelong late penalties.
Medicare Supplement (Medigap) Open Enrollment Period: A one-time 6-month period starting the month you enroll in Part B.
During this time, insurers cannot deny you coverage, charge higher premiums based on health, or impose waiting periods for pre-existing conditions.
This guaranteed-issue protection is available only once—miss it, and you may face medical underwriting or denials later.
Ideal time to add a Medigap plan for extra protection.
Special Enrollment Period (SEP) Triggered by qualifying life events, such as:
Losing employer group coverage (20+ employees)
Moving out of a plan’s service area
Other changes, like marriage, divorce, or loss of other coverage
Lasts 8 months (for employer-related events) or 2 months (for most others).
Allows penalty-free enrollment in Parts A/B, switching to/from Medicare Advantage or Part D, and avoiding gaps.
General Enrollment Period (GEP) for those who miss their IEP and don’t qualify for an SEP.
Runs January 1–March 31 each year.
Only for Original Medicare (Parts A and B); coverage starts July 1.
Late enrollment penalties usually apply.
Annual Enrollment Period (AEP) October 15–December 7 each year.
Make changes for the next year: switch Medicare Advantage plans, join or change Part D plans, or return to Original Medicare.
Changes take effect January 1.
