Special Note: If you’re born on the 1st of the month, your IEP starts 4 months before your 65th birthday.
Why It Matters: This is your first opportunity to enroll in Medicare Parts A and B. Delaying enrollment may lead to lifetime late penalties.
Timing: Varies by circumstance
8 months to enroll in Part B
63 days to enroll in Part D or Medicare Advantage (Part C)
Qualifying Events Include:
Losing employer or union coverage
Moving out of your current plan’s service area
Being misled or misinformed about your coverage

SEPs offer a valuable safety net when life changes unexpectedly. If any of these situations apply, it’s crucial to act quickly to avoid gaps in coverage.
Timing: October 15 – December 7 every year
Who It’s For: All Medicare beneficiaries
What You Can Do:
Switch between Original Medicare and Medicare Advantage
Change Medicare Advantage plans
Join, drop, or switch a Part D drug plan

This window is your chance to reassess your health needs and adjust your coverage accordingly.
Timing: January 1 – March 31
Who It’s For: People who missed their IEP

Caution: Enrolling during this period may lead to lifetime late penalties for Part B.
If you missed your IEP and don’t qualify for a SEP, this is your chance to get into the system—but penalties may apply.
