Can a Medicare Supplement Company Turn You Down in Florida? Yes — and Here Is Exactly When

“I applied for a Medigap plan and got denied because of my health history-how is that even legal when I’ve paid into Medicare for years?” That question was posted publicly on a consumer Medicare Q&A site, and some version of it reaches our Jacksonville office most weeks. The answer is not the one anybody wants. In Florida, if you apply for a Medicare Supplement policy outside one of a small number of protected windows, the carrier is allowed to ask about your health, and it is allowed to turn you down.

Here is why that is legal. A Medicare Supplement policy — most people say “supplement”, the industry says Medigap — is not Medicare. It is a private insurance policy sold under state regulation that pays part of what Original Medicare leaves you owing. Federal law creates one protected stretch when carriers have to sell to you regardless of your health. Medicare.gov describes what happens once it closes in flat language: “your options to buy a Medigap policy may be limited and the policy may cost more,” and outside that window “there’s no federal guarantee that an insurance company will sell you a Medigap policy.”

Some states have written extra rights on top of the federal floor. Florida has not written an annual one. That single fact changes the maths of every Medicare decision made in Duval County, and almost nobody says it plainly on the way in.

A decline is not a mistake. It is how the rules were built.

People assume that because Medicare is federal, everything attached to it is federal too. Medigap is the exception. Congress set a floor — one guaranteed open enrollment period, plus a defined list of guaranteed-issue situations — and then left the states free to add more. Medicare.gov says so on the same page: “These answers only apply to your federal rights. Contact your state to find out if your state offers more opportunities for you to buy a Medigap policy under state law.”

So the honest question is never “can they do this?” It is “which state am I in, and what did that state add?” In Florida, the answer to the second half is: a two-month window after group coverage ends, a second open enrollment for people who came onto Medicare before 65, a free look, and a renewal guarantee. Not an annual switching right. Everything else runs on the federal floor.

What does “medical underwriting” actually mean?

Nobody says “medical underwriting” at a kitchen table. They say “health questions”, and that is the right way to think about it. Underwriting is the step where a carrier looks at your health, decides whether to issue you a policy at all, and decides what to charge if it does. During your protected window that step is skipped entirely. Outside it, the step is back, and it is the carrier’s decision, not Medicare’s.

You can see the shape of it in what Florida law bothers to limit. Florida caps a pre-existing condition exclusion at six months and requires a carrier to credit prior creditable coverage against it. A rule like that only exists because applications ask about conditions you already have. Medicare.gov puts the pricing side just as plainly: outside your open enrollment period, if you are able to buy a policy at all, “it may cost more due to past or present health problems.”

This is also why the second question we hear so often has no clean answer. Someone asked publicly: “How likely am I to qualify for Medigap at 73 after the six-month enrollment period? I have some medical history and a possible cancer workup, but no diagnosis, hospitalizations, or treatment.” There is no published table that answers that. Each carrier sets its own rules, and a pending workup is exactly the kind of open question an underwriter dislikes. Any agent who tells you the outcome in advance is guessing.

The one window nobody can turn you down in

Your Medigap open enrollment period runs six months and starts the first day of the month you are both 65 or older and enrolled in Medicare Part B. Florida restates that federal rule in its own 2026 Medigap FAQ, and adds a wrinkle that catches people born on the first of the month: if your birthday falls on the first day of the month, your Part B coverage and your Medicare Supplement open enrollment both begin the first day of the previous month. If you were born on 1 September, your window opened in August.

Six months sounds generous until you watch it get spent. Two months disappear into paperwork and Social Security. One month goes to reading mail. By the time most people feel ready to compare anything, half the window is gone. Our guide to the 2026 Medicare enrollment periods maps how this one overlaps with your Initial Enrollment Period, which is a different seven-month clock with a different job.

Does Florida have a Medigap birthday rule?

No. A handful of states have added a yearly window — often tied to a policyholder’s birthday — in which someone who already has a Medigap policy can move to another carrier without health questions. Florida is not one of them. The Florida Office of Insurance Regulation publishes a document called “2026 Medigap Frequently Asked Questions”, and read end to end it contains no annual or birthday-based right to change carriers without underwriting. The word “birthday” appears there only inside the rule about when Part B coverage starts, which is an effective-date mechanic, not a switching right.

This matters more in Florida than it would almost anywhere, because Florida sells so much Medicare Advantage. In Duval County, 80% of Medicare Advantage prescription drug plans carry a $0 monthly premium for the 2026 plan year — 28 of 35 of them. A $0 premium is the normal condition of the market here, not a bargain someone found for you. And the decision it invites at 65 is the one that quietly closes the supplement door later.

What Florida law gives you instead

Florida is not silent on Medigap. It is silent on one specific thing. The rest of the state’s consumer protections are real, they are written down, and most people never learn they have them until an agent points at them. The statutory hook, per the Florida Department of Financial Services, is s. 627.6741, Florida Statutes, which requires companies to provide an open enrollment period and not to discriminate in pricing.

Read that table as a list of doors. Most of them open once, on a specific date, because of a specific event. None of them opens every year just because time passed.

The Medicare Advantage trial right: your twelve-month way back

This is the single most valuable rule on this page for anyone who has just enrolled, and it is the one that gets left out of the sales call. If you joined a Medicare Advantage plan when you first became eligible for Medicare Part A at age 65, and you leave that plan within one year of joining, you are eligible for any Medicare Supplement policy from any company on a guaranteed issue basis. No health questions. It is a federal right, restated in Florida’s own 2026 Medigap FAQ.

Notice how narrow the conditions are. It has to have been your first Medicare Advantage plan, taken when you were first eligible at 65, and you have to act inside twelve months. Miss the date by a week and the right is gone for good. This is why we tell every client who chooses Medicare Advantage at 65 to write the trial-right expiry on the same calendar as their birthday, and to actually use the first year to test the plan against real appointments rather than brochures.

If you are already past that window and thinking about moving, our walkthrough on switching from Medicare Advantage back to Original Medicare covers the mechanics of the move itself. Just understand that leaving Medicare Advantage and getting a supplement are two separate transactions, and only the first one is guaranteed.

What if you came onto Medicare before 65?

Florida treats you better than the federal floor does. If you qualified for Medicare under 65 because of a disability or end-stage renal disease, Florida gives you a six-month Medicare Supplement open enrollment period that starts on your Part B enrollment date. That is the same protection a 65-year-old gets, at whatever age Medicare started for you.

Then Florida does something else. When you turn 65, you get a second open enrollment period. That is genuinely unusual and genuinely useful, because the policies and prices available to someone at 65 are typically different from those available to a 52-year-old on Medicare by disability. If you came onto Medicare early, your 65th birthday is not a formality. It is a second chance at a decision you may have had to make under pressure years ago.

Set a reminder for the month you turn 64. Both of these windows are date-driven, and nobody at Medicare or the state is going to phone you to say the door is open.

Pre-existing conditions, six months, and the coverage that erases them

A pre-existing condition exclusion is a stretch of time at the start of a new policy during which the carrier will not pay for a condition you already had. Florida caps that stretch at six months. More usefully, Florida says the carrier cannot impose one at all if you had a continuous period of creditable coverage of at least six months as of the date you applied.

For most people moving from an employer plan, or from Medicare Advantage, or from another supplement, that second sentence does the work. Six months of continuous prior coverage and the exclusion disappears. The trap is a gap. If you let coverage lapse while you shop, you can hand a carrier back a six-month exclusion you did not need to give it.

So the rule is simple and it is not negotiable: never cancel what you have until the new policy has actually been issued. Not applied for. Issued, in writing, with an effective date on it.

What does it cost to be stuck without a supplement?

This is the part that makes the rest of the page matter. Original Medicare on its own has no annual limit on what you can spend. Medicare.gov describes Part B coinsurance as “usually 20% of the cost for each Medicare-covered service”, and there is no ceiling on that 20%. Twenty percent of a knee replacement and twenty percent of a cancer course are both twenty percent.

The fixed numbers underneath it are published every autumn by CMS. For the 2026 plan year the standard Part B premium is $202.90 a month and the annual Part B deductible is $283. The Part A inpatient hospital deductible is $1,736 for each benefit period — not each year, each benefit period, which can happen more than once in twelve months. After that, hospital coinsurance starts.

None of those bars is the scary one. The scary one is the number that does not appear: the 20% Part B coinsurance, which has no annual cap and therefore no bar to draw. A Medicare Supplement policy exists to close that. Being unable to buy one is not an inconvenience; it is an open-ended exposure for the rest of your life.

The 2026 numbers written into a Florida Medigap policy

Medigap plans are standardised by letter, which means Plan G from one company covers the same things as Plan G from another. What differs is price, service and the company behind it. Several plan letters also carry dollar figures that CMS resets each year, and Florida publishes the current ones in the same FAQ we have been quoting.

If you are choosing between letters rather than choosing whether to have a supplement at all, our side-by-side on Plan G versus Plan N in Florida works through the copay trade-off in detail. The decision on this page comes first, though. There is no point comparing letters you may not be eligible to buy.

Two protections you already have and probably do not know about

The first is the free look. A Medicare Supplement policy issued or delivered in Florida must contain a provision allowing you to return the policy or certificate within 30 days and receive a full refund. Thirty days is enough to read the actual contract rather than the brochure, check that the effective date matches what you were told, and confirm the plan letter is the one you asked for.

The second is bigger. All Medicare Supplement policies sold in Florida must be guaranteed renewable, and Florida law prohibits companies from cancelling them except for nonpayment of premium or material misrepresentation. Read that carefully, because it answers the question people are really asking when they ask whether a carrier can drop them. Getting sick is not on the list. Filing claims is not on the list. Lying on the application is.

Guaranteed renewable is not the same as a fixed premium. Your rate can rise, and this is where the second Florida agency enters.

Who regulates this in Florida, and who do you call?

Most agency websites blur the two Florida agencies into one. They do different jobs, and knowing which is which saves you an afternoon on hold. The Department of Financial Services deals with people — it licenses and disciplines agents and runs the consumer helpline. The Office of Insurance Regulation deals with companies — it regulates carriers and has to approve any Medicare Supplement rate increase before that increase takes effect.

The Department of Financial Services gives Floridians one instruction we would put on a fridge magnet: contact us to verify the license of the agent and the insurance company before you sign an application for a policy. It takes about ninety seconds. Everyone in Florida selling you a Medicare product should survive that search comfortably, including us.

So what should you do before you enroll in anything at 65?

Everything above collapses into one practical instruction: protect the option before you need it. The six-month window is the only period in which every door is open, so the work belongs in front of it, not after. Here is the sequence we walk clients through, and it works whether or not you ever call us.

1. Find your exact Part B effective dateNot your birthday. Your Part B start date, from your Medicare card or your Medicare.gov account. Your six-month Medigap open enrollment is welded to it, and if your birthday falls on the first of the month, both dates shift a month earlier.
2. Write the closing date on a calendar in inkCount six months from the first day of that month and mark the last day. That is the date after which a carrier may start asking health questions. Put a second reminder 60 days before it.
3. Build three lists before you look at a single planEvery doctor you intend to keep, every prescription with its exact dose, and the hospital you would actually want to be taken to. Comparing plans without these three lists is comparing premiums, which is the least useful number on the page.
4. Decide the supplement question first, not lastAsk yourself whether you want the ability to buy a Medicare Supplement later. If the honest answer is yes, buy it now, inside the window, because “later” is where the health questions live. Our Advantage versus Supplement comparison lays out both sides.
5. If you choose Medicare Advantage anyway, date the trial rightWrite down the day you joined and the same day twelve months later. Inside that year you can leave and buy any Medigap policy from any company on a guaranteed issue basis. Use the year deliberately — book the appointments, fill the prescriptions, see whether the network holds.
6. Verify the license before you sign anythingSearch the agent and the carrier at licenseesearch.fldfs.com. It is the Florida Department of Financial Services’ own instruction to consumers, and it is free.
7. Make every number you are shown carry a plan yearA Medicare figure without a year attached is not a fact, it is a leftover. Ask “is that the 2026 number?” and watch what happens.
8. Get a second opinion that has nothing to sellCall SHINE at 1-800-963-5337 or 1-800-MEDICARE, and compare what they say to what your agent says. If the two versions disagree, you have learned something important about your agent.

Bring your current plan and your prescription list; we’ll do the comparison with you.

Before and after: two versions of the same decision

Before. Ray is 65, lives in Arlington, and takes a Medicare Advantage plan in his birthday month because the mailer said $0 and $0 is hard to argue with. It is a reasonable plan and he is healthy for eight years. At 73 his cardiologist moves out of the network, and Ray decides he would rather be on Original Medicare with a supplement. He applies, answers the health questions, and is declined. Nothing about that is unlawful in Florida, and nobody misled him. He stays where he is, and his exposure in a bad year is his plan’s in-network out-of-pocket maximum, which at the Duval County median is $6,750 for the 2026 plan year.

After. Same man, same health, one different month. Inside his six-month Medigap open enrollment he buys a standardised Medicare Supplement policy with no health questions asked. At 73 his cardiologist’s network status is irrelevant, because Original Medicare has no network. The trade-off is real and we say it out loud: he pays a monthly premium in every one of those eight years, that premium rises over time, and rate increases are reviewed by the Florida Office of Insurance Regulation rather than frozen. He bought predictability, and predictability is not free.

Illustrative example only. Ray is not a client and these are not quotes. The $6,750 figure is the median in-network out-of-pocket maximum across Duval County Medicare Advantage plans for the 2026 plan year, published by CMS; the county range runs from $2,500 to $9,250.

What if you took Medicare Advantage five years ago?

Then the trial right has expired and we are not going to pretend otherwise. Your remaining routes to a Medicare Supplement are a federal or Florida guaranteed-issue situation, or an application that goes through health questions and may be declined. That is the whole list. Anyone offering you a third route in Florida is describing another state’s rules.

What you can still do without anyone’s permission is change Medicare Advantage plans. Medicare.gov describes two annual chances: the Open Enrollment Period from 15 October to 7 December, with coverage starting 1 January and the request in the plan’s hands by 7 December, and the Medicare Advantage Open Enrollment Period from 1 January to 31 March, when someone already in a Medicare Advantage plan may switch to another Medicare Advantage plan or drop back to Original Medicare.

That second window is worth understanding precisely, because it lets you leave Medicare Advantage but says nothing about whether a supplement carrier will take you afterwards. Those are two separate doors, and only one of them is guaranteed to open. Apply rather than assume, since underwriting rules differ by carrier — and do the applying before you cancel anything.

You were declined. What do you do this week?

First, do not cancel your existing coverage. Whatever you have — a Medicare Advantage plan, a retiree plan, another supplement — keep it until something else is issued in writing. A decline plus a lapse is a much worse position than a decline.

Second, ask the carrier what the decision was based on, and ask for it in writing. Applications are sometimes declined on a data error, an old code that was never corrected, or a condition recorded under the wrong name. You cannot correct a record you have not seen.

Third, check whether you actually sit inside a protected window and did not realise it. The two-month Florida window after group coverage ends catches a lot of people who retired later than planned. So does the second open enrollment at 65 for anyone who came onto Medicare early. Both are on the table above.

Fourth, call SHINE at 1-800-963-5337. They have nothing to sell you, they know the Florida rules, and they will tell you whether a guaranteed-issue situation applies. Then, if you do buy a policy from anyone, remember the 30-day free look: you have a month to read it properly and return it for a full refund.

The trade-off nobody puts in the mail

We are not here to tell you Medicare Advantage is a trap. That would be its own kind of dishonesty. For plenty of people in Duval County a Medicare Advantage plan is a sound choice: the local market is deep, with 12 parent organisations offering plans in the county for the 2026 plan year, and CMS rated 61 of the 84 rated Duval plans at four stars or better, with a mean overall rating of 4.19.

What a Medicare Advantage plan costs you is not usually money on day one. It is optionality. You are trading a lower monthly outlay now for a future in which the alternative may require someone’s approval. If you are 65 and healthy and money is tight, that can be a perfectly rational trade — as long as you make it knowing what is on the other side of it.

How we help

McDowell Business Resources is an independent agency in Jacksonville. We are not an insurance carrier, and we are not affiliated with or endorsed by the U.S. government, the federal Medicare program or CMS. We do not offer every plan available in your area, which is exactly why we tell you to check Medicare.gov and call 1-800-MEDICARE for the full picture, and SHINE at 1-800-963-5337 for free counselling that has no commercial interest in your answer.

What we do is concrete. We find your Part B effective date and calculate the exact last day of your Medigap open enrollment window. We run your doctors and your prescriptions against the plans we represent rather than against a brochure. We tell you which of the Florida protections in the table above apply to your situation right now, and which do not. If you are inside a guaranteed-issue situation, we say so. If you are outside every one of them and an application will carry health questions, we say that too, before you apply.

Then we do it again each autumn, because plans change, and because the only thing worse than a decision made in a hurry is one that nobody revisits for eight years.

What you get from deciding this on the rules

You get to stop guessing. The Medicare mail is designed to make one product look obviously free and every alternative look like an expense, and it never mentions the six-month clock or the twelve-month trial right, because neither helps sell anything today. Once you know both dates, the choice becomes a normal financial decision with a known trade-off instead of a coin flip you will not be able to unflip.

If you are approaching 65 in Jacksonville, Orange Park, St. Augustine or Fernandina Beach, the single most useful hour you can spend is the one where somebody reads the Florida rules to you before the window opens. Whatever you decide, decide it on the numbers. If you want help getting to them, we’re here.
