Original Medicare covers approximately 80% of most medical costs after your deductible. The remaining 20% coinsurance has no annual cap, which means a serious illness or extended hospital stay can result in thousands of dollars in out-of-pocket costs.

Medicare Supplement plans, also called Medigap, are private insurance policies that cover these gaps. They work alongside Original Medicare to reduce or eliminate your out-of-pocket costs for covered services.

Florida has a large and competitive Medigap market. Multiple insurers offer standardized plans, which means the benefits are identical across insurers for the same plan letter. The only difference is the premium you pay and the insurer's financial stability and customer service reputation.

Key Takeaways

Medigap plans are standardized by letter: A Plan G from Humana covers exactly the same benefits as a Plan G from Aetna or Blue Cross. The only differences between insurers for the same plan letter are the premium, the insurer's financial rating, and customer service quality.
Plan G is the most popular Medigap plan in Florida: Plan G covers the Part B coinsurance (20%), Part A coinsurance and hospital costs, the Part A deductible, skilled nursing facility coinsurance, and foreign travel emergency care. The only cost not covered is the Part B deductible ($257 in 2026).
Plan N offers lower premiums with some cost-sharing: Plan N covers the same benefits as Plan G except you pay up to $20 copays for office visits and up to $50 for emergency room visits. Plan N premiums are typically 20% to 30% lower than Plan G premiums.
Plan F is no longer available to new Medicare enrollees: Plan F was the most comprehensive Medigap plan, covering the Part B deductible as well. It is no longer available to people who became eligible for Medicare on or after January 1, 2020. If you were eligible before that date, you may still be able to enroll in Plan F.
The Medigap Open Enrollment Period is your best window to enroll: You have a 6-month Medigap Open Enrollment Period starting when you are both 65 or older and enrolled in Part B. During this window, insurers cannot deny you coverage or charge you more based on your health. Outside this window, Florida insurers can use medical underwriting.
Florida uses attained-age rating for most Medigap plans: Most Medigap insurers in Florida use attained-age rating, which means your premium increases as you get older. Issue-age rated and community-rated plans are also available from some insurers and may offer better long-term value depending on your situation.

How Medigap Plans Work in Florida

Medigap plans work alongside Original Medicare (Parts A and B). When you receive a covered service, Medicare pays its share first, then your Medigap plan pays its share based on the plan's coverage.

What Medigap does not cover:

Prescription drugs (you need a separate Part D plan)
Dental, vision, or hearing care
Long-term custodial care
Private-duty nursing

Who can buy Medigap in Florida: You must be enrolled in both Medicare Part A and Part B to buy a Medigap plan. You cannot have a Medigap plan and a Medicare Advantage plan at the same time.

Medigap vs. Medicare Advantage: These are two different approaches to Medicare coverage. Medigap supplements Original Medicare and gives you unrestricted access to any Medicare-accepting provider. Medicare Advantage replaces Original Medicare with a private plan that has a network. For a detailed comparison, see our guide on the best Medicare plans for seniors.

Comparing the Most Popular Medigap Plans in Florida

Florida beneficiaries have access to all standardized Medigap plan letters. The three most commonly purchased plans are G, N, and (for those eligible) F.

Benefit	Plan G	Plan N	Plan F*
Part A coinsurance and hospital costs	100%	100%	100%
Part B coinsurance	100%	100% (with copays)	100%
Part A deductible ($1,676)	100%	100%	100%
Part B deductible ($257)	Not covered	Not covered	100%
Skilled nursing coinsurance	100%	100%	100%
Foreign travel emergency	80%	80%	80%
Office visit copay	None	Up to $20	None
ER copay (non-admitted)	None	Up to $50	None

*Plan F is only available to those who became Medicare-eligible before January 1, 2020.

Plan G vs. Plan N decision: If you visit the doctor frequently or have ongoing specialist care, Plan G's no-copay structure may be worth the higher premium. If you are generally healthy and rarely visit the doctor, Plan N's lower premium may save you money overall even after accounting for the copays.

Medigap Premiums in Florida 2026

Because Medigap benefits are standardized, shopping for the lowest premium from a financially stable insurer is the primary way to save money on Medigap in Florida.

Typical 2026 monthly Medigap premiums in Florida (age 65, non-tobacco):

Plan	Monthly Premium Range	Annual Cost Range
Plan G	$120 to $220	$1,440 to $2,640
Plan G (High Deductible)	$35 to $65	$420 to $780
Plan N	$90 to $160	$1,080 to $1,920
Plan F (if eligible)	$140 to $250	$1,680 to $3,000

Premiums increase with age under attained-age rating, which is the most common rating method in Florida. A Plan G that costs $150 per month at age 65 may cost $200 or more per month by age 75.

Tobacco surcharges: Most Florida Medigap insurers charge tobacco users 10% to 25% more than non-tobacco users. Quitting tobacco before applying for Medigap can result in significant premium savings.

When to Enroll in Medigap in Florida

The timing of your Medigap enrollment significantly affects your ability to get coverage and the premium you pay.

The Medigap Open Enrollment Period (OEP): This is the most important enrollment window. It begins on the first day of the month in which you are both age 65 or older and enrolled in Medicare Part B, and lasts for 6 months. During this window, Florida Medigap insurers cannot deny you coverage or charge you more based on your health history. This is the best time to enroll.

After the OEP: Outside the OEP, Florida Medigap insurers can use medical underwriting. They can ask about your health history, charge higher premiums based on pre-existing conditions, or deny coverage entirely. This is why enrolling during the OEP is so important.

Guaranteed issue rights: Certain situations trigger a guaranteed issue right that allows you to enroll in Medigap outside the OEP without underwriting. These include losing employer coverage, your Medicare Advantage plan leaving your area, and (for first-time Medicare Advantage enrollees) the trial right within the first 12 months.

How to Shop for Medigap in Florida

Because Medigap benefits are standardized, the shopping process is straightforward once you have chosen a plan letter.

Step 1: Choose your plan letter. For most new enrollees, the choice is between Plan G and Plan N. Consider your typical healthcare usage, your risk tolerance for out-of-pocket costs, and the premium difference.

Step 2: Compare premiums from multiple insurers. Get quotes from at least 3 to 5 insurers. Florida has many Medigap insurers including Humana, Aetna, Cigna, Mutual of Omaha, United American, and others. Premiums for the same plan can vary by 30% or more between insurers.

Step 3: Check the insurer's financial rating. Look for insurers with an A.M. Best rating of A or better. Medigap is a long-term commitment and you want an insurer that will be financially stable for decades.

Step 4: Enroll during your OEP. Submit your application during your 6-month Medigap Open Enrollment Period to guarantee acceptance regardless of your health status.
