Medicare Plan G vs Plan N: Which Is Better in Florida?

Plan G and Plan N differ in exactly three ways: Plan N charges a copay of up to $20 for some office visits and up to $50 for an emergency room visit that does not end in admission, Plan N does not cover Part B excess charges, and Plan N costs less per month. Plan G is the better plan for you when the premium you would save on Plan N is smaller than the copays and excess charges you would actually pay; Plan N is better when the saving is bigger.

That is the whole comparison, and in Florida it has two local wrinkles that change the arithmetic: the state permits excess charges, and it requires issue-age pricing. The rest of this post walks through what each plan pays, how the copays really work, how to find your own break-even point with real Florida quotes, and the one rule about switching later that makes this a longer-term decision than it looks.

What is the difference between Plan G and Plan N?

Medicare Supplement plans, also called Medigap, are standardized by letter. A Plan G from one carrier pays the same benefits as a Plan G from any other; what differs is the premium and the company. That standardization is what makes the G-versus-N comparison so clean. Here is the federal benefit chart for the two plans, from Medicare.gov’s plan comparison (Medicare.gov), with the 2026 dollar amounts from CMS (CMS.gov):

Read the table top to bottom and the pattern is obvious. The big-ticket items, a hospital stay, a skilled nursing stay, the 20% coinsurance on a surgery or a course of chemotherapy, are paid in full by both plans. Neither plan touches the Part B deductible. The differences live in two small rows, and the premium row is the price the carrier puts on them.

One point worth stating plainly, because it confuses people who came to Medicare after 2020: Plan F, which did cover the Part B deductible, is closed to anyone who became eligible for Medicare on or after January 1, 2020. For most people shopping today, Plan G is the most complete plan on the shelf, and Plan N is the most complete plan below it. The question is whether the two small gaps are worth the premium difference.

How do Plan N copays actually work?

The exact wording on Medicare.gov is worth quoting, because the copays are smaller and narrower than people assume: “Plan N pays 100% of the costs of Part B coinsurance. You must pay a copayment of up to $20 for some office visits and up to $50 for emergency room visits when you aren’t admitted as an inpatient” (Medicare.gov).

Three things follow from that sentence:

• “Up to.” The copay is a ceiling, not a flat fee. On a visit where Medicare’s 20% coinsurance comes to less than $20, you pay the smaller amount.
• “Some office visits.” The copay attaches to visits billed as office visits with a physician. It is not a charge on every interaction with the health system; lab work, imaging, outpatient surgery and hospital care are not office visits and carry no Plan N copay.
• “When you aren’t admitted.” The $50 emergency room copay is waived if the ER visit turns into an inpatient admission. The visit that most worries people, the one that becomes a hospital stay, is the one with no copay.

There is no annual cap on the copays. That is the honest weakness of Plan N compared with Plan G, and it is why frequency of care, not severity, is the variable that decides between them. A person with one major surgery in a year pays roughly the same on either plan, because the surgery itself is covered in full by both. A person who sees three specialists monthly pays a copay at each visit on Plan N and nothing on Plan G.

What are Part B excess charges, and does Florida allow them?

The second gap is the one people either overrate or forget entirely. A Part B excess charge is the extra amount a doctor who does not accept Medicare assignment may bill you above the Medicare-approved amount. Medicare.gov’s rule: “In many cases, the charge can’t be more than 15% above the Medicare-approved amount for non-participating healthcare providers” (Medicare.gov). Plan G pays that charge; Plan N does not.

Two facts put the exposure in proportion:

• Most doctors do not bill them. The same Medicare.gov page states that “most doctors, providers, and suppliers accept assignment, but always check to make sure that yours do.” MedPAC, the federal commission that advises Congress on Medicare payment, puts it the same way: almost all clinicians billing the physician fee schedule do so as participating providers, meaning they accept Medicare’s fee schedule amount as payment in full (MedPAC).
• The 15% is smaller than it sounds. CMS explains that non-participating physicians are paid 95% of the fee schedule amount, and the limiting charge is 115% of that reduced figure, which works out to 109.25% of the ordinary fee (CMS.gov). The true premium over what a participating doctor would have charged is about 9.25%.

Florida is one of the states that permits excess charges, so the exposure exists here in a way it does not in the handful of states that have banned them. Whether it exists for you is a question about your own doctors, not about Florida: if your primary care physician, cardiologist and orthopedist all accept assignment, Plan N’s second gap is worth nothing. If the one specialist you see most is non-participating, it is worth something every visit. We work through the full arithmetic in what Medicare Part B excess charges are and which plans cover them.

How much cheaper is Plan N than Plan G?

There is no national answer, and any post that quotes one is quoting a marketing average. Medigap premiums are set by carrier, plan letter, age at issue and county, and Florida publishes the filed rates. The Florida Office of Insurance Regulation’s CHOICES tool lets you pull current Plan G and Plan N premiums for your age in Hillsborough, Pinellas, Pasco, Sarasota or any other county, carrier by carrier (Florida OIR). Two quotes from the same carrier, subtracted, give you the one number the whole decision turns on: your annual premium gap.

Once you have that gap, the break-even is simple arithmetic. Because the largest Plan N copay is $20, every $240 of annual saving buys twelve office-visit copays before Plan G would have been the cheaper year. The table below shows the shape of it using illustrative gaps, not quotes:

The right-hand column is the key. Most retirees in a normal year do not see a physician in the office twelve times, let alone thirty-six. That is why Plan N tends to win in ordinary years even at a modest premium gap, and why it can still win in a hospital year, since the hospital stay itself carries no Plan N copay.

What the table leaves out is excess charges, because they cannot be tabulated in advance. If your regular specialist is non-participating, add roughly 9.25% of that doctor’s Medicare-approved charges for the year to the Plan N side of the ledger before comparing.

If you would rather let a tool do this, our Plan G vs Plan N comparison calculator takes your two real quotes, your expected number of office and ER visits, and any excess charges, and shows which plan pencils out lower across a full year.

Which plan costs less in a light year and a heavy year?

Putting the pieces together, here are three illustrative years side by side. The Medicare figures are the 2026 amounts from CMS; the premium gap is a placeholder of $480 a year, which you would replace with your own. Neither column includes the premiums themselves or the $283 Part B deductible, which both plans leave to you.

Two things stand out. First, the hospital year is not the year that hurts Plan N, because the $1,736 Part A deductible and the inpatient care are paid in full by both plans, and the ER copay disappears on admission. Second, the year that does hurt Plan N combines two things: high visit frequency and a non-participating doctor. One without the other rarely closes a $480 gap.

That is the frame. What your own gap is, and how many visits and which doctors your year actually holds, are facts only you have.

Can you switch from Plan N to Plan G later?

This is the question to settle before you buy, because it does not have the answer most people expect. The instinct is to start on Plan N while healthy and move to Plan G if care becomes frequent. The problem is the door you would need to walk through.

Medicare.gov is direct: outside your six-month Medigap open enrollment period, you generally cannot switch policies except in specific situations, and if you do, “you may have to pay more for the new policy and answer some medical questions” (Medicare.gov). In practice, a move from Plan N to Plan G after your window closes is a new application, and the carrier is allowed to underwrite it. The diagnosis that makes you want Plan G is often the diagnosis that lets the carrier decline you.

There are exceptions, and they are narrow:

• Guaranteed issue rights. Certain events, such as a Medicare Advantage plan leaving your area or an employer plan ending, create a window in which carriers must sell you specific Medigap plans without health questions (Medicare.gov). They are event-driven, not something you can schedule. We walk through them in what happens if you miss your Medigap open enrollment window.
• The 30-day free look. If a carrier does approve a switch, Medicare.gov gives you 30 days on the new policy before you must cancel the old one. Do not cancel Plan N until Plan G is in force.
• Carrier-specific rules. Some companies let existing policyholders move between their own plan letters with reduced or no underwriting. That is company policy, not law, and it changes. Get it in writing before relying on it.

The reverse move, from Plan G down to Plan N, is easier in one respect: some carriers treat a reduction in benefits more leniently. But it is still an application, and it still depends on the company. The safe assumption is that the plan you buy at 65 is the plan you keep, so choose the one you would be content to hold at 80.

What is different about Plan G vs Plan N in Florida?

Three Florida rules shape this comparison in ways a national article cannot.

Florida permits excess charges. As above, this is the reason Plan N’s second gap has any value here, and the reason Plan G’s premium reflects it. A Florida shopper cannot dismiss excess charges the way a shopper in one of the banning states can, but should also not overweight them; whether they matter depends on the assignment status of the specific doctors you see.

Florida requires issue-age pricing. The Florida Department of Financial Services states that all Florida Medicare Supplement policies “must be sold on an ‘issue age basis.’ This means that an individual’s premium will not increase due to age as they get older” (Florida DFS). Medicare.gov describes issue-age pricing the same way: the premium is based on your age when you buy, and does not rise as you get older, though it can still rise for inflation and other reasons (Medicare.gov). For this comparison it means the premium gap you measure at 65 is the gap the plans were priced at for your entry age, not one that shrinks or widens with each birthday, as it would under attained-age pricing in many other states. We explain the three rating methods in do Medicare Supplement premiums go up with age.

Florida runs its own open enrollment rules, and publishes the rates. The state’s open enrollment period “begins the first day of the month a person turns 65 and is enrolled in Medicare Part B” and runs six months, matching the federal window. Florida also goes further than federal law: since October 1, 2009, section 627.6741 of the Florida Statutes has required a six-month open enrollment period for people who become eligible for Medicare Parts A and B through disability before 65, and a two-month guaranteed issue window after employer group coverage ends (Florida DFS; Florida Statutes 627.6741). And the filed rates for every carrier, plan letter, age band and county are public in the CHOICES tool, so a Tampa Bay shopper can put Plan G and Plan N side by side before speaking to anyone.

Who tends to choose Plan G, and who tends to choose Plan N?

Plan design should follow your cash flow, your doctors and your temperament, not a guess about future health that nobody can make reliably. The profile that usually lands on Plan G:

• Frequent, predictable care. Several specialists, regular follow-ups, a condition that means office visits most months. The copays would add up and the premium gap would not cover them.
• A non-participating specialist you intend to keep. If the surgeon or oncologist you trust does not accept assignment, Plan G removes the excess-charge exposure entirely.
• A preference for zero paperwork. After the $283 Part B deductible, a Plan G year is silent. For some people that predictability is worth more than the premium difference, and that is a rational choice, not a timid one.

The profile that usually lands on Plan N:

• Light or moderate use. A handful of office visits a year, doctors who accept assignment, and a premium gap that would cover several times that many copays.
• A budget where the premium saving stays saved. Plan N works when the difference sits in reserve for the occasional copay or an unexpected excess charge, not when it is absorbed into monthly spending.
• Comfort with a small variable bill. A $20 copay at the front desk does not bother everyone. If it would, Plan G’s premium buys peace of mind.

What neither profile should do is pick Plan N as a placeholder with a plan to upgrade later. Underwriting stands between you and that upgrade, and it gets taller with time.

How to decide between Plan G and Plan N in an afternoon

1. Pull two quotes for your age and county from the CHOICES tool or a licensed agent, from the same carrier, for Plan G and Plan N. Subtract to find your annual premium gap.
2. Count last year’s office visits honestly, and multiply by $20. That is your realistic copay exposure. Add $50 for any ER visit that did not end in admission.
3. Check your doctors’ assignment status. Ask each office directly, or look them up on Medicare.gov’s provider search, which shows whether a clinician accepts assignment. If every doctor you see is participating, excess charges are a non-issue for you today.
4. Compare the gap with the exposure. If the gap is larger by a comfortable margin, Plan N is the lower-cost plan for the way you use care. If it is close or smaller, Plan G is.
5. Decide the plan you want at 80, not just at 65, and buy it during your open enrollment window if you can, so the decision is made on price rather than on health questions. Our enrollment timeline tool shows your exact Medigap window from your date of birth.
6. Total the year. The annual Medicare cost estimator adds the Part B premium of $202.90 a month in 2026, your Medigap premium, your Part D premium and the $283 deductible into a single figure, so the two plans are compared on the whole year rather than on the premium alone.

The verified 2026 Medicare figures this post relies on are collected in the 2026 Medicare numbers, verified, and if you are weighing a lower-premium Plan G instead of Plan N, is high-deductible Plan G worth it in 2026 puts all three on one table.
