Florida Medigap Supplement Plans — Which Plan Is Right for You 2026

By the Florida Plan Finder Team · Licensed Florida Health Insurance Producer · NPN #21249133 · Last Updated: May 4, 2026

Original Medicare is powerful — it's accepted by nearly every doctor and hospital in the country — but it has significant cost-sharing exposure. The Part A hospital deductible ($1,676 per benefit period in 2026), the 20% Part B coinsurance with no out-of-pocket maximum, and SNF daily coinsurance can add up to tens of thousands of dollars in a bad health year. That's where Medigap comes in.

Medicare Supplement (Medigap) plans are sold by private insurance companies and are designed to work alongside Original Medicare, picking up the costs that Medicare doesn't pay. In Florida, there are 10 standardized Medigap plan types (A through N, with some letters retired), and the most popular are Plan F, Plan G, and Plan N. This guide walks you through how they compare, what they cost, and how to choose the right one for your situation.

Standardized Benefits Explained

Federal law requires that Medigap plans be standardized across all insurers. This means that a Plan G from Aetna and a Plan G from Mutual of Omaha cover the exact same benefits — not more, not less. The only difference is the monthly premium you pay. This is a huge consumer protection: you don't have to decode complex benefit grids to figure out what's covered. Every Plan G covers the same things.

This standardization also means comparison shopping for Medigap is straightforward. Once you decide which plan letter fits your needs, you simply compare premiums among carriers offering that letter in your Florida county. A licensed agent can pull quotes from multiple carriers simultaneously to find the best available rate.

Plans F, G, and N Compared

Below is a benefit-by-benefit comparison of the three most commonly purchased Medigap plans in Florida. A checkmark means the plan covers that benefit; an X means it does not.

Plan G vs Plan N: Cost Analysis

For most new Medicare enrollees in Florida in 2026, the real choice comes down to Plan G versus Plan N. Both cover the most significant gaps — the Part A deductible, SNF coinsurance, and Part B's 20% coinsurance. The differences are modest but meaningful depending on your health habits and doctor preferences.

Plan G advantages

• Covers 100% of Part B coinsurance with no copays at office visits.
• Covers Part B excess charges — important if you see doctors who don't accept Medicare assignment (who can charge up to 15% above the Medicare-approved amount).
• True "set it and forget it" coverage: after the $257 annual Part B deductible, your out-of-pocket for covered services is essentially zero.

Plan N advantages

• Typically $20–$50/month cheaper in premium than Plan G in Florida.
• A good fit for healthier beneficiaries who see the doctor infrequently — the premium savings often exceed the modest copays.
• Does not cover Part B excess charges, but this is rarely an issue if you stay with Medicare-assignment doctors (over 98% of Florida physicians accept Medicare assignment).

Issue-Age vs Attained-Age Rating in Florida

Unlike most states that mandate only one premium rating method, Florida allows Medigap carriers to use either issue-age rating or attained-age rating — and the difference significantly affects how your premiums grow over time.

Attained-age rating sets your premium based on your current age, increasing automatically as you get older each year (on top of any general medical inflation increases). Premiums tend to start lower in your mid-60s but escalate significantly by your 70s and 80s.

Issue-age rating bases your premium on the age at which you first enroll and does not increase simply because you're getting older. Premiums can still rise due to medical cost inflation, but they won't jump because you turned 70. Issue-age plans typically start somewhat higher but become more cost-effective over a long retirement.

When to Buy: Guaranteed Issue and Open Enrollment

The most important window for buying Medigap is your Medigap Open Enrollment Period: a 6-month window that begins the first month you're both age 65 or older AND enrolled in Medicare Part B. During this window, no carrier can deny you coverage, charge you more, or impose waiting periods based on your health history. This is federal law and it's ironclad.

Outside this window, Florida does not require carriers to offer guaranteed issue Medigap policies (with limited exceptions, such as losing employer coverage or moving out of an MA plan's service area). This means if you wait and develop a health condition, you may find it difficult or expensive to get Medigap coverage later — carriers can use medical underwriting and decline your application.

Top Medigap Carriers in Florida

Florida's Medigap market is competitive, with dozens of carriers offering Plan G and Plan N across the state. Premiums can vary significantly from one carrier to another for identical benefits — differences of $50–$100/month are not uncommon. The following carriers are among the most active and well-rated in Florida's Medigap market in 2026:

Because Medigap benefits are identical across carriers, the right choice for you depends on price, rating method, financial strength, and any available discounts (many carriers offer 5–12% household discounts when two members of a household both purchase policies).
