Medicare Supplement Plans in Florida: Comparing Medigap Options A Through N

If you’re turning 65, retiring, or approaching Medicare eligibility in Florida, you’ve probably been bombarded with mail, calls, and ads about Medicare Supplement insurance — also called Medigap.

The volume of information is overwhelming. The stakes are high. And the differences between plans matter enormously to your wallet.

Here’s a clear, honest guide to Florida Medigap plans — what they cover, how they’re priced, and how to make the right choice for your situation.

What Original Medicare Leaves Uncovered

Before you can understand Medigap, you need to understand the gaps in Original Medicare (Parts A and B):

Medicare Part A gaps (hospital):

• Hospital deductible: $1,632 per benefit period in 2024 (not per year — per spell of illness)
• Days 61–90: $408/day coinsurance
• Days 91+: $816/day coinsurance (lifetime reserve days)
• Skilled nursing facility days 21–100: $204/day coinsurance

Medicare Part B gaps (medical/outpatient):

• Annual Part B deductible: $240 in 2024
• 20% coinsurance on all covered outpatient services — with no out-of-pocket maximum
• Foreign travel: Not covered

That 20% Part B coinsurance with no cap is the big exposure. One cancer treatment course, one major surgery, one extended illness — and 20% of Medicare-approved amounts adds up very fast.

Medigap fills these gaps. Different plans fill different amounts.

How Florida Medigap Plans Are Standardized

Every Medigap plan sold in Florida must conform to federal standardization rules. A Plan G from Blue Cross is identical in benefits to a Plan G from Humana — the same 10 plan letters (A, B, D, G, K, L, M, N) mean the same coverage at every carrier.

What varies between carriers: premium pricing and claims service quality.

This is critically important: because benefits are identical for any given plan letter, the only reason to pay more for the same plan letter at a higher-premium carrier is… nothing. Price matters. Shop every available carrier.

The Main Florida Medigap Plans Compared

Plan G — The Most Popular Choice for New Enrollees

What it covers:

• Part A deductible: ✅
• Part A coinsurance and hospital costs (365 extra days): ✅
• Part B coinsurance (20%): ✅
• Part B excess charges: ✅
• Skilled nursing facility coinsurance: ✅
• Foreign travel emergency (80% up to limits): ✅

What it doesn’t cover:

• Part B deductible ($240/year): ❌

Plan G is as close to comprehensive Medigap coverage as currently available to new Medicare enrollees. The only thing you pay beyond your premium is the annual Part B deductible of $240.

Why it’s the top choice: After paying the $240 Part B deductible, your coverage is effectively 100% of Medicare-approved costs. No co-pays, no coinsurance, no surprise bills from covered services.

Florida average monthly premiums for Plan G (age 65, non-smoker):

• Lowest available: $90 – $120/month
• Mid-range: $130 – $170/month
• Higher-end carriers: $180 – $220/month

Because benefits are identical, buying the lower-premium option from a financially solid carrier is almost always the right call at Plan G.

Plan N — The Budget-Conscious Alternative

What it covers:

• Part A deductible: ✅
• Part A coinsurance: ✅
• Part B coinsurance: ✅ (with cost-sharing: up to $20 copay per office visit, up to $50 per ER visit)
• Skilled nursing facility coinsurance: ✅
• Foreign travel emergency: ✅

What it doesn’t cover:

• Part B deductible: ❌
• Part B excess charges: ❌
• Full Part B coinsurance (you pay copays at each visit): ❌ (partial)

Florida average monthly premiums for Plan N (age 65, non-smoker):

• Lowest available: $65 – $90/month
• Mid-range: $95 – $130/month

Plan N costs roughly $30–$50/month less than Plan G. The trade-off: you pay up to $20 per doctor visit and up to $50 per emergency room visit (waived if admitted). You’re also exposed to Part B excess charges — what doctors who don’t accept Medicare assignment can bill above Medicare-approved rates.

Plan N makes sense if: You’re relatively healthy, don’t anticipate frequent office visits, and your Florida doctors accept Medicare assignment (most do). The premium savings over 5 years can exceed $3,000.

Plan G High-Deductible — For Budget-Minded, Healthy Seniors

This plan has the same benefits as Plan G, but you pay a high deductible ($2,800 in 2024) before benefits kick in. After the deductible, coverage is identical to Plan G.

Florida average monthly premiums: $30 – $55/month

This plan makes sense for: very healthy seniors who want catastrophic protection while keeping premiums very low. If you go multiple years without significant medical needs, the premium savings can far exceed the occasional deductible.

Plan A — Bare Minimum (Rarely Recommended)

Covers only Part A coinsurance, Part A hospital costs, Part B coinsurance, and preventive care coinsurance. Does NOT cover the Part A deductible — meaning a hospital stay starts with $1,632 out of pocket.

Plan A is the cheapest Medigap plan and rarely the right choice. The Part A deductible exposure alone makes it a poor value for most Florida seniors.

Plans K and L — Cost-Sharing Plans

These plans cover a percentage of costs rather than 100%. Plan K covers 50% of most gaps; Plan L covers 75%. Both have annual out-of-pocket caps ($7,060 for K, $3,530 for L in 2024).

They’re rarely popular in Florida because the cost-sharing makes benefit calculation complex, and Plan N usually offers better value for a similar premium.

Open Enrollment: Your Most Important Window

When you first enroll in Medicare Part B (typically the month you turn 65), you have a 6-month Medigap Open Enrollment Period. During this window:

• No carrier can deny you coverage based on health status
• No carrier can charge you more due to pre-existing conditions
• You can buy any Medigap plan offered in Florida

After this window closes, Florida Medigap carriers can use medical underwriting — they can deny your application, charge you more, or exclude pre-existing conditions based on your health history.

This is not a window to miss. If you don’t buy during open enrollment and develop health problems later, you may find yourself uninsurable for Medigap — stuck with Original Medicare’s gaps forever.

Florida exception: Florida offers a birthday rule — once per year during the 60-day window following your birthday, you can switch from one Medigap plan to another plan with equal or lesser benefits, guaranteed issue regardless of health. This provides some flexibility after open enrollment, but only for lateral or downgrade moves — not upgrades.

Medicare Advantage vs. Medigap: The Key Decision

When you first enroll in Medicare, you choose a path: Medicare Advantage (Part C) or Original Medicare + Medigap.

This is the most important Medicare decision most Florida seniors make:

Medicare Advantage: All-in-one plans managed by private insurers. Usually lower monthly premiums (sometimes $0), but you’re subject to network restrictions, referral requirements, prior authorizations, and co-pays. Coverage quality varies dramatically by plan and county.

Original Medicare + Medigap: Keep any Florida doctor who accepts Medicare, no referrals, no network limits. Your predictable costs are the Medigap premium plus Part D drug plan premium.

Which is better? Depends on your health, where you live, how often you travel, and your financial situation. High-utilizers of healthcare often find Medigap’s unlimited coverage more valuable. Healthy seniors who value low premiums may prefer Medicare Advantage.

What’s harder to reverse: switching from Medicare Advantage back to Medigap requires passing medical underwriting in Florida (except during special circumstances). Getting onto a Medigap plan while healthy is easier than getting onto one after health issues develop.

How to Shop Florida Medigap Plans

Step 1: Determine which plan letter fits your needs and budget. Most new enrollees choose Plan G or Plan N.

Step 2: Compare every carrier offering that plan letter in your Florida ZIP code. Because benefits are identical, lower premium = better deal (assuming carrier financial stability).

Step 3: Check carrier financial ratings (A.M. Best A or better) and rate increase history. Some carriers offer low initial rates and then aggressively raise premiums. Ask your agent to show you 5-year rate increase history for any carrier you’re considering.

Step 4: Work with an independent Medicare specialist — not a captive agent for one carrier, and not a website that gets paid to steer you to high-commission plans. Independent brokers who specialize in Medicare can compare all available Florida carriers at once.

Step 5: Also enroll in a Medicare Part D prescription drug plan — Medigap doesn’t cover drugs. Part D plans vary in formulary and premium; match the plan to your specific medications.

Florida-Specific Medigap Considerations

Florida has a large Medicare population, which means strong carrier competition and generally good plan availability. Most major national Medigap carriers — AARP/UnitedHealthcare, Mutual of Omaha, Cigna, Humana, Aetna, Blue Cross Blue Shield of Florida — actively compete in the Florida market.

Florida’s warm climate attracts snowbirds and retirees from around the country. If you travel or spend part of the year elsewhere, Original Medicare + Medigap gives you coverage anywhere in the U.S. Medicare Advantage plans typically restrict you to a local service area.

The Bottom Line

Florida Medigap plans — particularly Plan G and Plan N — provide the most predictable and comprehensive coverage available to Medicare-eligible seniors. Open enrollment is your best opportunity to buy without underwriting. Miss it, and future coverage may cost more or be unavailable.

For most Florida seniors who can pass underwriting and can budget for the monthly premium, Medigap is the foundation of a sound retirement healthcare plan.

Work with an independent Medicare broker, compare at least 5–8 carriers, and enroll during your open enrollment window. This decision is too important to make in a rush or based on one agent’s pitch.
