Turning 65 in Florida: Your Medicare Enrollment Checklist

Your Initial Enrollment Period

Most people become eligible for Medicare the month they turn 65. Your Initial Enrollment Period (IEP) is a 7-month window: the 3 months before your birthday month, your birthday month itself, and the 3 months after. If you enroll in the months before or during your birthday month, coverage typically starts the first of your birthday month. If you enroll in the 3 months after, coverage starts the month after you sign up.

Step-by-Step Checklist

• 3-4 months before your 65th birthday: Confirm whether you or your spouse have active employer coverage that lets you delay Medicare without penalty, or whether you should enroll during your IEP.
• Sign up for Part A and Part B through Social Security (many people are auto-enrolled if already receiving Social Security benefits; otherwise you’ll need to apply).
• Decide: Medicare Advantage, or Original Medicare plus Medigap and Part D. This is the biggest decision and it’s worth comparing both paths for your specific health needs and budget.
• If choosing Medicare Advantage, check that your current doctors and prescriptions are covered by plans available in your ZIP code (Fort Myers, Naples, Cape Coral, Bonita Springs, and Estero all have different plan availability).
• If choosing Original Medicare, apply for a Medigap policy during your Medigap Open Enrollment Period, which starts the month your Part B becomes effective — this is the best time to get a Medigap policy without medical underwriting.
• Either way, enroll in a Part D prescription drug plan if you don’t already have drug coverage through a Medicare Advantage plan, to avoid a late-enrollment penalty.

Still Working? Special Rules Apply

If you or your spouse are still working and covered by an employer group health plan with 20 or more employees, you may be able to delay Medicare Part B without penalty until that coverage ends. In that case, you’d qualify for a Special Enrollment Period once employment or coverage ends. It’s worth confirming the specifics with your employer’s HR or benefits department before your 65th birthday, since the rules differ for smaller employers.

Common Mistakes People Make

• Missing the Initial Enrollment Period window entirely and facing a lifelong Part B late-enrollment penalty.
• Assuming COBRA or retiree coverage counts the same as active employer coverage for delaying Medicare — it generally doesn’t.
• Waiting past the Medigap Open Enrollment Period, when medical underwriting can apply.
• Not comparing Medicare Advantage and Original Medicare + Medigap before choosing, and later wanting to switch.
