Medigap vs. Medicare Advantage in Florida

In Florida, Original Medicare with a Medigap policy works with any provider in the U.S. that accepts Medicare and leaves few bills when you get care, in exchange for a monthly Medigap premium plus a Part D plan. Medicare Advantage uses a county-based network and charges copays as you go, up to a yearly limit. Florida has no Medigap birthday rule, so the choice you make at 65 matters most.

How does each option work?

Original Medicare with Medigap: Medicare pays first for hospital and medical care, and your Medigap policy pays some or all of what's left, such as deductibles and the 20% Part B coinsurance. You add a standalone Part D plan for drugs. See Medigap in Florida.

Medicare Advantage: a private plan approved by Medicare replaces Original Medicare for your Part A and Part B care. Most plans include Part D, use a provider network, and charge copays or coinsurance as you use care, up to a yearly limit. See Medicare Advantage in Florida.

You need Part A and Part B either way, and you keep paying your Part B premium either way. In Florida, 3,051,948 of 5,344,538 people with Medicare were in Medicare Advantage or another Medicare health plan in July 2026, and 2,292,590 in Original Medicare, per CMS.

How do the costs compare?

Cost	Original Medicare + Medigap + Part D	Medicare Advantage
Monthly premium	Part B, plus the Medigap premium, plus the Part D premium.	Part B, plus the plan's premium if it has one.
Bills when you get care	Depends on the plan letter. Plan G leaves you the Part B deductible; Plans K, L and N leave more cost sharing.	Copays or coinsurance for most services, set by the plan.
Yearly limit on medical costs	None in Original Medicare alone. Plan K's limit is $8,360 and Plan L's $4,180 in 2027; with Plan G, very little is left to pay.	Required: up to $9,850 in network in 2027 (a PPO's combined limit can be up to $14,800).
Drug costs	Through a Part D plan, capped at $2,400 in 2027.	Usually included, with the same $2,400 cap.
How premiums change	Florida law bars attained-age pricing, where a premium rises automatically as you age (s. 627.410(6)(d)), and the Department of Financial Services says Florida Medigap policies are sold on an issue-age basis. Premiums can still rise for everyone in a plan, but the Office of Insurance Regulation must approve each rate change first (rule 69O-156.012).	Premiums and benefits can change every January 1; your Annual Notice of Change shows what's new.
Doctors who charge above Medicare's rate	Federal limits apply: a provider who doesn't take assignment can charge up to 15% more. In Florida, doctors must accept Medicare's approved amount for emergency care, and specialists your doctor sends you to must accept it if your doctor does, unless you agree otherwise in writing first (s. 456.056). Plans F and G cover excess charges.	You pay the plan's cost sharing for in-network care.

Medicare Advantage plans may offer extra benefits such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.

Networks, counties, snowbird travel and storms

Question	Original Medicare + Medigap	Medicare Advantage
Which doctors and hospitals?	Any provider in the U.S. who accepts Medicare.	The plan's network. HMOs generally cover out-of-network care only for emergencies and urgent care; PPOs cover it at a higher cost.
Referrals and prior approval	No referrals. Medicare's rules decide what's covered.	Many plans need referrals or prior authorization for some services.
Choice where you live	The same in every Florida county.	Depends on the county. For 2027, Hillsborough County has 52 plans open to everyone, Miami-Dade {{fl:plans.counties.Miami-Dade.ma:n}}, Leon 13 and Monroe 7.
Months in another state	Works the same in every state, so it suits snowbirds.	Tied to one permanent home. Emergencies and urgent care are covered anywhere in the U.S.; routine care away usually isn't in an HMO. More than 6 months in a row away ends your enrollment unless the plan has a visitor or traveler program (42 CFR 422.74).
Travel outside the U.S.	Plans C, D, F, G, M and N pay 80% of emergency care for the first 60 days of a trip, after a $250 deductible, up to a $50,000 lifetime limit.	Generally not covered; check the plan's Evidence of Coverage.
After a hurricane	Any provider who accepts Medicare, wherever you evacuate.	When a disaster is declared and access is disrupted, plans must cover non-network facilities at in-network cost sharing (42 CFR 422.100(m)).

Switching later: why Florida's rules matter

Florida's Medigap law (Fla. Stat. ss. 627.671 to 627.675, and rule chapter 69O-156) has no birthday rule, anniversary rule or yearly switching right. It does add protections federal law doesn't have. This table shows when a company must sell you a policy without health questions:

Change	Health questions?	Rule
Buy Medigap in your first 6 months when you're both 65 and in Part B	No	Medigap open enrollment, s. 627.6741(1)(a)1 and federal law
Buy Medigap under 65 with Medicare because of a disability or end-stage renal disease, within 6 months of Part B	No; companies must offer their policies, usually at higher under-65 rates, with a new open enrollment at 65	s. 627.6741(1)(a)1; rule 69O-156.009
Your group health coverage ends, such as an employer or union plan	No, if you apply within 2 months after it ends	s. 627.6741(1)(a)2, a Florida-only right
Switch Medigap policies later	Usually yes	No Florida birthday rule
Leave Medicare Advantage for Medigap	Usually yes	No health questions only with a guaranteed-issue right
Leave Medicare Advantage within 12 months of joining it for the first time (trial right)	No	Federal guaranteed issue
Your Medicare Advantage plan ends, leaves your county, or you move out of its area	No, for certain plan letters	Federal guaranteed issue (rule 69O-156.0095); apply up to 63 days after coverage ends
Switch Medicare Advantage plans	No	October 15 to December 7, and January 1 to March 31

In short: in Florida it's easier to start with Medigap and move to Medicare Advantage later than the other way around. When you do buy a Medigap policy, you have 30 days to return it for a full refund (s. 627.674), and a new policy can't refuse to pay for a pre-existing condition for more than 6 months (s. 627.6741(2)).

Other Florida factors to weigh

State Group Insurance retirees: you can stay in a State plan that pays after Medicare, or join one of the State's group MA-PD plans. A retiree who cancels State Group Insurance can't come back later. See State Group Insurance vs. individual Medicare plans.
Florida Medicaid: with full Medicaid you usually don't need Medigap, and Florida law generally bars selling you one while you have Medicaid. People with full Medicaid must get it through a Statewide Medicaid Managed Care plan, and may qualify for a D-SNP. See D-SNP vs. Original Medicare and Florida Medicaid.
Military and veterans: TRICARE For Life pays after Medicare and requires Part A and Part B. See military, veterans and TRICARE in Florida.
Moving here: a Medigap policy from another state keeps working in Florida; a Medicare Advantage plan usually doesn't. Some states give extra Medigap switching rights, but those rights don't come with you to Florida. See moving to Florida with Medicare.
Plans ending in 2027: at least 302,773 Floridians in regular Medicare Advantage plans must choose new coverage. If that's you, this is a rare chance to buy Medigap without health questions. See Florida plans ending in 2027.

How to decide

List your doctors, hospitals and drugs. Include specialists and any provider in another state where you spend time.
Check what's sold in your county. Look up your county on our counties page and check each plan's network for your providers.
Compare a typical year and a bad year. Add premiums and expected copays, then compare with the plan's out-of-pocket limit or your Medigap plan's coverage.
Think about time away. If you spend months outside Florida, weigh how each option handles care there.
Mind your timing. Your Medigap open enrollment at 65, or within 2 months after group coverage ends, is when any company must sell you a policy at a price not based on your health.

To compare Medigap policies and Medicare Advantage plans from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code. The Office of Insurance Regulation's CHOICES rate comparison tool shows sample Medigap rates. Complaints about an agent or Medigap company go to the DFS Division of Consumer Services.

Frequently asked questions

Is Medigap or Medicare Advantage better in Florida?

Neither is better for everyone. Medigap with Original Medicare suits people who want any provider in the U.S. who accepts Medicare, live part of the year in another state, or want predictable bills. Medicare Advantage suits people comfortable with a local network who want drug coverage and possible extra benefits in one plan.

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

No. A Medigap policy doesn't pay anything while you're in Medicare Advantage, and it's illegal for a company to sell you one then unless you're switching back to Original Medicare. If you already have Medigap and join Medicare Advantage for the first time, you may want to keep it during your 12-month trial period.

If I choose Medicare Advantage, can I switch to Medigap later in Florida?

You can return to Original Medicare during Open Enrollment or the January to March window, but outside a guaranteed-issue situation a Medigap company can ask health questions and turn you down. Florida law has no birthday rule or yearly switching right.

Can I get Medigap under 65 in Florida?

Yes, if you have Medicare because of a disability or end-stage renal disease. Florida law gives you a 6-month Medigap open enrollment once you're in Part B, and companies that sell Medigap in Florida must offer their policies to you. Premiums are usually higher before 65, and you get a new open enrollment at 65.

Do I need a separate drug plan with Medigap?

Yes. Medigap policies don't cover prescriptions, so most people with Medigap also join a standalone Part D plan. CMS lists 11 standalone Part D plans in Florida for 2027. Most Medicare Advantage plans include drug coverage.
