Turning 65 is a Medicare milestone. But the system doesn’t automatically enroll most people, and missing key deadlines can mean permanent penalties. Here’s a clear checklist to guide you through the process.
6 Months Before Your 65th Birthday
Start researching now. Understand the difference between Original Medicare and Medicare Advantage. Decide whether you want a Medigap supplement. Look at Part D drug plans in your area and check if your medications are covered. Give yourself time to make a thoughtful decision rather than a rushed one.
3 Months Before Your Birthday Month
Your Initial Enrollment Period (IEP) opens — it runs for 7 months total (3 months before your birthday month, your birthday month, and 3 months after). Enrolling in Part A and B during the first 3 months means your coverage starts on the first day of your birthday month.
If you’re already receiving Social Security benefits, you’re automatically enrolled in Parts A and B. Your card will arrive in the mail.
If you’re not on Social Security yet, you need to actively enroll at SSA.gov or by visiting your local Social Security office.
During Enrollment: Key Decisions
Decide on your coverage path. Option 1: Original Medicare (Parts A + B) + Medigap + Part D drug plan. Option 2: Medicare Advantage (Part C) which bundles A, B, and usually D together, often with dental and vision added.
Compare plans at Medicare.gov. Check that your doctors and prescriptions are covered under any plan you’re considering.
Still Working at 65?
If you have qualifying employer coverage through an active employer (yours or your spouse’s), you may delay Medicare without penalty. Confirm your employer coverage is “creditable” — meaning it’s at least as good as Medicare. Keep documentation in case you need to prove it later.
After Enrollment: Final Steps
Set up your MyMedicare.gov account. Shred your old insurance cards if Medicare is now your primary coverage. Let your doctors know your new coverage. Set a calendar reminder for the Annual Enrollment Period (October 15 – December 7) so you can reassess your plan each year.
