Your 7-month window
| When you sign up | When coverage starts |
|---|---|

If you already get Social Security benefits at least 4 months before you turn 65, you'll be enrolled automatically and your card arrives about 3 months ahead. Otherwise, apply online at ssa.gov/medicare/sign-up, by calling 1-800-772-1213 (TTY 1-800-325-0778; press 7 for Spanish), or at a Social Security office.
What's different in Florida?
- State Group Insurance retirees: once you're eligible for Medicare, the State plan pays after Medicare and as if you had Part B, whether or not you do. Have Part A and Part B in place by your 65th birthday month. If you want one of the State's group Medicare Advantage plans, People First must receive your Medicare card; requests after the 20th of a month start the first day of the second month after. See Florida state retirees and Medicare.
- Medigap timing: Florida has no birthday rule, so plan your Medigap decision for the 6 months after your Part B starts.
- Snowbirds: choose your plan for the state that's your permanent residence. Medicare Advantage and Part D plans are tied to it; Original Medicare and Medigap work nationwide.
- Help paying: if your income is limited, apply for a Medicare Savings Program through ACCESS Florida at the same time; see Medicare Savings Programs in Florida.
When waiting is OK
If you or your spouse have group coverage from current work at an employer with 20 or more employees, you can usually delay Part B and sign up within 8 months after that job or coverage ends. COBRA and retiree coverage don't count. See working past 65.
For the full timeline, use the turning 65 in Florida guide. To compare coverage before your Medicare starts, you can request a call from a licensed insurance agent to go over plans from the companies they work with.

Frequently asked questions
What if I sign up during my birthday month?
Your coverage starts the first day of the next month. Signing up in any of the 3 months after your birthday month also starts coverage the month after you sign up, so waiting means a short period without Medicare if you have no other coverage.
My birthday is on the 1st. Does that change anything?
Yes. Social Security treats you as turning 65 the day before, so your window and coverage start a month earlier: your coverage can begin the first day of the month before your birthday month.
Does my Medigap clock start when I sign up?
It starts when your Part B starts, as long as you're 65. Florida has no birthday rule, so that 6-month Medigap open enrollment is your main guaranteed chance to buy a policy. Delaying Part B because of job coverage delays this window too, and Florida adds 2 months after group coverage ends.
