Medicare Supplement Plans Florida: How to Pick a Letter and Time It Right

If you have settled on Original Medicare, the next question is what to do about the bills it leaves behind. Original Medicare pays most of a hospital stay or a specialist visit, but you owe deductibles and 20% coinsurance with no yearly ceiling, and one bad year can be expensive. The Medicare supplement plans Florida companies sell, also called Medigap, exist to pick up much of that share.

The good news is that the choice is narrower than it first looks. Every plan letter carries the same benefits no matter which company sells it, so there are really three decisions: which letter, when to buy, and which company’s pricing you trust to hold up over the years.

How Medigap Fits With Original Medicare

Medicare pays its part of a covered bill first, then your Medigap policy pays some or all of the rest, depending on the letter you hold. You need both Part A and Part B to buy one, and you keep paying your Part B premium to Medicare on top of the separate Medigap premium.

A standard Medigap policy has no network. Any doctor or hospital in the country that accepts Medicare will take it, and you do not need a referral to see a specialist. For someone who spends summers up north, that is often the deciding feature. If you are still deciding between this route and an all-in-one plan, our comparison of Original Medicare and Medicare Advantage in Florida lays out how the two paths differ.

Three limits are worth knowing from the start. Medigap policies sold today do not cover prescriptions, so you pair one with a standalone Part D plan. Routine dental, vision, hearing aids and long-term custodial care are outside it too. And each policy covers one person, so a married couple buys two, which can be different letters from different companies.

The Lettered Plans and the Plan G vs Plan N Decision

Federal rules fix what each letter pays. A Plan G from one company covers exactly what a Plan G from any other company covers, which means you can choose the letter first and shop the companies second. People new to Medicare can choose from Plans A, B, D, G, K, L, M and N. Plans C and F are closed to anyone who became eligible for Medicare on or after January 1, 2020.

Plan G: the fewest bills

Plan G pays the Part A hospital deductible, hospital and skilled nursing coinsurance, Part B coinsurance and Part B excess charges. The one gap you cover yourself is the yearly Part B deductible, which is $283 in 2026. After that, covered care typically costs you little or nothing for the rest of the year.

Excess charges are the reason Plan G appeals to people who see a lot of specialists. A doctor who does not accept Medicare’s approved amount as full payment can, in many cases, bill up to 15% above it. Medicare calls this the limiting charge. Plan G absorbs it; several other letters leave it with you.

Plan N: a lower premium with small copays

Plan N usually costs less each month, and in return you share a little more. You pay the Part B deductible, a copay of up to $20 for some office visits, and up to $50 for an emergency room visit that does not end in an inpatient admission. Plan N does not pay excess charges.

Plan N tends to suit healthy people who see a handful of doctors a year, mostly ones who accept Medicare’s rate. Plan G tends to suit people with ongoing specialist care or anyone who would rather pay a higher premium than think about copays. The premium gap between them varies by company and ZIP code, so price both.

The other letters

Plans K and L pay a percentage of many costs and cap what you spend in a year: $8,000 for Plan K and $4,000 for Plan L in 2026, plus the Part B deductible. A high-deductible version of Plan G is also sold; in 2026 you pay up to $2,950 in Medicare-covered costs before the policy starts paying. These can make sense for people with solid savings who mainly want protection against a catastrophic year.

Your Medigap Open Enrollment Period Happens Once

Timing matters more with Medigap than with almost anything else in Medicare. Your six-month Medigap open enrollment period starts the first month you are 65 or older and enrolled in Part B. During those six months, a company cannot refuse to sell you any policy it offers or charge you more because of your health. It does not repeat.

If you are still working at 65 and delay Part B because you have coverage through a current employer, the window waits with you and opens when Part B starts. That is why the date you choose for Part B deserves some thought.

Florida’s own rules

Florida law extends this protection in two useful ways. People under 65 who have Medicare because of a disability or end-stage renal disease also get a six-month open enrollment period once they are enrolled in Part B. And if you are enrolled in Part B when group health coverage ends, Florida gives you two months to apply, during which a company must accept you without basing the decision or the price on your health. The details are in section 627.6741 of the Florida Statutes.

Even during open enrollment, a policy can make you wait up to six months before covering a pre-existing condition. That wait can be shortened or waived if you had continuous creditable coverage beforehand, which is common for people coming straight off employer or Marketplace coverage.

What Changes After the Window Closes

Outside a protected window, a Medigap company in Florida can ask health questions, review your records, and decline you or charge more. Healthy applicants are often accepted, but people with heart conditions, diabetes or a recent cancer diagnosis can find it hard to change plans later.

Guaranteed issue rights

Federal law gives you the right to buy certain Medigap policies regardless of health in specific situations, such as a Medicare Advantage plan leaving your area, losing employer retiree coverage that supplemented Medicare, or your Medigap company going out of business. You can generally apply as early as 60 days before the old coverage ends and no later than 63 days after it ends. Keep every letter that shows the date your coverage stopped, because the new company will ask for proof.

Trying Medicare Advantage first

If you joined a Medicare Advantage plan when you first became eligible at 65, you have a trial right: within the first year, you can switch to Original Medicare and buy a Medigap policy without health questions. If you dropped a Medigap policy to try Medicare Advantage for the first time, you can generally get that same policy back within the first year, as long as the company still sells it. People who have been in Medicare Advantage longer than that usually face underwriting, so check whether you would qualify before you leave a plan. If you are weighing a move in either direction, our guide to comparing Medicare Advantage plans in Florida covers the other side of the decision.

Assured Insurance Services can sit down with you, ask about your health, your doctors and how much of the year you spend away from Florida, and help you work out when your window opens and how a supplement fits into your wider Medicare decision. Call 772-220-7600 to set up a time.

How Medigap Pricing Works Over the Years

Because benefits are identical within a letter, price is where companies differ, and the first-year premium tells you only part of the story. Companies set premiums in one of three ways.

Community, issue-age and attained-age rating

A community-rated policy generally charges everyone the same premium regardless of age. An issue-age-rated policy is priced on your age when you buy it and does not go up because you get older. An attained-age-rated policy is based on your current age and rises as you age, so it often starts lowest and climbs. Any of the three can still rise with medical costs, so ask each company which method it uses and how its rates for your letter have moved in recent years.

Your ZIP code and tobacco use can also affect what you pay, and some companies offer discounts. The Medicare guide to choosing a Medigap policy explains the rating methods in more detail and includes the full benefit chart for every letter.

Comparing like with like

Line up Plan G against Plan G and Plan N against Plan N. Note the current premium, the rating method and the company’s rate history side by side. Every Medigap policy issued since 1992 is guaranteed renewable, so as long as you pay the premium the company cannot cancel you because of your health.

Medigap for Snowbirds and Trips Abroad

Medigap’s nationwide reach is its biggest draw for part-year Floridians, but trips outside the U.S. are different. Original Medicare generally does not cover care abroad. Plans C, D, F, G, M and N include a foreign travel emergency benefit that pays 80% of eligible emergency costs, with a $250 yearly deductible, a $50,000 lifetime limit, and coverage only for emergencies that begin within the first 60 days of a trip. It helps on a cruise or a vacation abroad but is no substitute for travel medical coverage on a long stay overseas. Medicare’s fact sheet on coverage outside the United States sets out these limits.

Some companies also sell Medicare SELECT policies, which carry the same standard benefits but require you to use network hospitals, and in some cases doctors, for full coverage. They can cost less, but if you split the year between two states, read the network rules closely before choosing one.

Pick the Letter, Then the Company

When you are ready to talk it through, the team at Assured Insurance Services will look at how you use care, explain where Plan G and Plan N would differ for someone in your position, and help you weigh Original Medicare with a supplement against the Medicare Advantage route, with Spanish-speaking help if you prefer. They do not offer every plan available in every area, and Medicare.gov or Florida SHINE (1-800-963-5337) can show you all of your options. You can see the Medicare options we help with or book a Medicare review whenever it suits you.

Frequently Asked Questions

Can I keep my Medigap policy if I move to Florida from another state?

Yes. A standard Medigap policy stays with you as long as you remain in Original Medicare and keep paying the premium, though the price may be adjusted for your new address. If you have a Medicare SELECT policy, you may need to change plans, since its network may not reach Florida.

Can I have a Medigap policy and a Medicare Advantage plan at the same time?

No. Medigap only works with Original Medicare, and a company generally cannot sell you a Medigap policy while you are enrolled in Medicare Advantage unless that coverage is ending. If you already hold Medigap and join Medicare Advantage, you would usually drop the Medigap policy.

Is there a trial period after I buy a new Medigap policy?

Yes. You have 30 days to look over a new policy and decide whether to keep it. If you are replacing an existing policy, keep the old one in force during those 30 days, which means paying both premiums briefly, so you are never without coverage.

Can I switch from Plan G to Plan N later to lower my premium?

You can apply at any time, but outside a protected window the new company can usually ask health questions and decline you. If your health is good, a later switch is often possible; just keep your current policy until the new one is approved and in force.
