Turning 65 in Florida: The Complete Medicare Enrollment Checklist for 2026

Turning 65 is a milestone — and for most Americans, it's the moment Medicare becomes available. But Medicare enrollment is not automatic for everyone, the decisions you make in the months around your 65th birthday can affect your coverage and costs for years, and the rules are genuinely confusing.

I help people navigate this transition every day in Northeast Florida. Here's the complete checklist — what to do, when to do it, and what happens if you miss a deadline.

Your Initial Enrollment Period is a 7-month window centered on your 65th birthday month:

• 3 months before your birthday month
• Your birthday month
• 3 months after your birthday month

Example: If your birthday is September 15, your IEP runs June 1 – December 31.

When you enroll within this window affects when your coverage starts:

The takeaway: Enrolling in the 3 months before your birthday month gives you the earliest possible coverage start date. Don't wait until your birthday month if you want coverage to start on time.

☐ Determine whether you need to actively enroll

If you're already receiving Social Security benefits when you turn 65, you'll be automatically enrolled in Medicare Parts A and B. You'll receive your Medicare card in the mail about 3 months before your 65th birthday.

If you're NOT receiving Social Security, you must actively enroll. Most people enroll online at ssa.gov, by calling Social Security at 1-800-772-1213, or by visiting a local Social Security office.

☐ Decide whether to take Part B now or delay

If you have employer-sponsored health insurance through your own (or your spouse's) current employment at a company with 20+ employees, you may be able to delay Part B without penalty. This is called a Special Enrollment Period — you can enroll in Part B within 8 months of losing that employer coverage.

If your employer has fewer than 20 employees, Medicare becomes primary — you should enroll in Part B at 65 even if you have employer coverage.

☐ Start researching your Medicare options

The three main paths:

1. Original Medicare (Parts A + B) + Medigap + Part D — maximum flexibility, nationwide coverage, higher monthly premiums
2. Medicare Advantage (Part C) — bundled coverage, often $0 premium, network restrictions
3. Original Medicare only — not recommended; leaves you exposed to unlimited cost-sharing

☐ Enroll in Part A (if not automatic)

Part A (hospital insurance) is free for most people (you paid into it through payroll taxes). There's almost never a reason to delay Part A enrollment.

☐ Enroll in Part B (if not delaying due to employer coverage)

Part B covers outpatient care, doctor visits, preventive services, and durable medical equipment. The standard 2026 premium is $202.90/month, deducted from your Social Security benefit or billed directly if you're not yet collecting Social Security.

☐ Apply for Medigap if you're going that route

If you're choosing Original Medicare + Medigap, your Medigap Open Enrollment Period begins the first month you're both 65 and enrolled in Part B. During this 6-month window, you have guaranteed issue rights — insurance companies cannot deny you coverage or charge you more based on pre-existing conditions.

This is the most important window in your Medicare life for Medigap. Once it closes, you can be denied or charged more based on health conditions.

The most popular Medigap plans in Florida:

• Plan G: Covers everything except the Part B deductible ($283 in 2026). Most comprehensive option.
• Plan N: Covers everything except the Part B deductible and certain copays ($20 for office visits, $50 for ER). Lower premium than Plan G.
• Plan G High Deductible: Lower premium; you pay the first $2,870 (2026) before coverage kicks in. Good for healthy people who want catastrophic protection.

☐ Compare Medicare Advantage plans in your county

If you're considering Medicare Advantage instead of Medigap, use Medicare's Plan Finder at medicare.gov/plan-compare to see all plans available in your ZIP code. Compare:

• Monthly premium
• Out-of-pocket maximum
• Your doctors' network participation
• Your medications' formulary coverage
• Extra benefits (dental, vision, hearing, OTC)

☐ Confirm your Medicare card has arrived

If you were automatically enrolled, your Medicare card should have arrived 3 months before your birthday. If it hasn't, call Social Security.

☐ Enroll in Part D (prescription drug coverage)

If you're on Original Medicare + Medigap, you need a standalone Part D plan for prescription drug coverage. If you're on Medicare Advantage, drug coverage is typically included.

Important: Even if you don't take any medications, you should enroll in a low-cost Part D plan to avoid the Part D late enrollment penalty — 1% of the national base premium for every month you go without creditable drug coverage. This penalty is permanent.

☐ Finalize your plan selection

By your birthday month, you should have:

• Medicare Parts A and B active (or confirmed enrollment)
• A Medigap plan selected and applied for (if going that route)
• A Part D plan selected (or Medicare Advantage with drug coverage)

☐ Set up your MyMedicare.gov account

Create an account at mymedicare.gov to:

• View your Medicare Summary Notices (claims billed in your name)
• Track your deductible and out-of-pocket spending
• Check for potential fraud or billing errors

☐ Schedule your Welcome to Medicare preventive visit

Within the first 12 months of Part B enrollment, you're entitled to a one-time "Welcome to Medicare" preventive visit. This is a review of your health and risk factors — not a physical exam, but a valuable baseline. It's covered at 100% with no cost-sharing.

☐ Understand your Annual Wellness Visit

After your first year on Medicare, you're entitled to a free Annual Wellness Visit every year. This is different from a regular physical — it's a preventive visit focused on health risk assessment and preventive care planning. Take advantage of it.

If you don't enroll in Part B when you're first eligible (and you don't have a valid reason to delay), you'll pay a 10% premium surcharge for every 12-month period you were eligible but didn't enroll. This penalty is permanent — it follows you for life.

Example: You delay Part B for 2 years without a valid reason. Your Part B premium is permanently increased by 20% — from $185.00 to $222.00/month. Over 20 years, that's over $8,800 in extra premiums.

If you go 63 or more consecutive days without creditable prescription drug coverage after becoming eligible for Medicare, you'll pay a 1% penalty for every month without coverage, added permanently to your Part D premium.

Example: You go 24 months without Part D coverage. Your penalty is 24% of the national base premium (approximately $37.06 in 2026), added to your monthly Part D premium — permanently.

There's no government penalty for delaying Medigap enrollment — but there's a practical one. After your Medigap Open Enrollment Period closes, insurance companies can use medical underwriting to deny you coverage or charge you more. If you develop a health condition and then try to get Medigap, you may be unable to get it at any price.

If you're still working and covered by employer insurance at a company with 20+ employees, you can delay Part B without penalty. When you retire or lose that coverage, you have an 8-month Special Enrollment Period to sign up for Part B.

Important: COBRA does not count as employer coverage for this purpose. If you're on COBRA, enroll in Medicare during your IEP.

If you've been receiving Social Security Disability Insurance (SSDI) for 24 months, you're already enrolled in Medicare — regardless of your age. When you turn 65, you transition from disability Medicare to regular Medicare, and your coverage options expand.

If you're moving to Florida and turning 65, your Medicare options depend on your new county of residence. Medicare Advantage plans are county-specific — a plan available in your old state may not be available in Florida. You'll have a Special Enrollment Period to choose a new plan when you move.

Navigating Medicare for the first time is genuinely complex. The decisions you make during your Initial Enrollment Period — particularly around Medigap — can be difficult or impossible to reverse later.
