Snowbirds: Medicare Advantage vs. Medigap

For people who split the year between Florida and another state, Original Medicare with a Medigap policy works with any provider in the U.S. that accepts Medicare, in both places, with no time limit. Medicare Advantage ties routine care to one service area and ends after more than 6 months away unless the plan has a visitor or traveler program. Florida has no Medigap birthday rule, so switching to Medigap later can mean health questions.

How each option works for a snowbird

Original Medicare with Medigap: Medicare pays first for hospital and medical care with any doctor or hospital that accepts Medicare, anywhere in the U.S. Your Medigap policy pays some or all of what's left, such as deductibles and the 20% Part B coinsurance, wherever Medicare pays. 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 serve a set of counties around your permanent home. 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.

Care in two homes

Question	Original Medicare + Medigap	Medicare Advantage
Routine care in your other state	Any provider in the U.S. who accepts Medicare.	Depends on the plan. HMOs usually need in-network providers in the plan's area; some plans pay out of network at a higher cost.
Emergencies and urgent care away	Covered anywhere in the U.S.	Covered anywhere in the U.S. (42 CFR 422.113).
Time limit away from home	None.	More than 6 months in a row outside the service area ends your enrollment (42 CFR 422.74(d)(4)).
Visitor or traveler programs	Not needed.	Optional for plans: can cover you for more than 6 but less than 12 months away, in areas and with providers the plan chooses.
Referrals and prior approval	No referrals. Medicare's rules decide what's covered.	Many plans need referrals or prior authorization for some services, wherever you are.
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; some plans offer emergency coverage abroad as an extra benefit.
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)).

A Medicare SELECT policy is the exception on the Medigap side: it requires its network hospitals, and sometimes doctors, for full benefits outside emergencies, so check where that network is.

How 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 set by the plan; out-of-network care, if covered, usually costs more.
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.	Required: up to $9,850 in network in 2027 (a PPO's combined limit can be up to $14,800).
Drug costs	Through a standalone Part D plan, capped at $2,400 in 2027.	Usually included, with the same $2,400 cap.
How premiums are set in Florida	Florida bars attained-age premium structures on Medigap policy forms sold mostly to people 65 and older (Fla. Stat. 627.410(6)(d)), and the Office of Insurance Regulation must approve rate changes. Premiums can still rise for everyone in a plan.	Premiums and benefits can change every January 1; your Annual Notice of Change shows what's new.

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.

Prescriptions either way

Whichever you choose, your drug coverage is tied to your permanent residence, and out-of-network pharmacies are covered only when you can't reasonably reach a network pharmacy, not for routine refills (42 CFR 423.124). Before you choose, check that the plan's pharmacy network includes pharmacies near both homes, and ask about mail order. A standalone Part D plan allows up to 12 months away before disenrollment; a Medicare Advantage plan's drug coverage ends with the plan after more than 6 months away. See snowbird prescriptions in Florida and up north.

Switching later: why Florida's rules matter

Florida's Medigap law (Fla. Stat. 627.671 to 627.675, and rule 69O-156) has no birthday rule, anniversary rule or yearly switching right. That makes the direction you move important.

Change	Health questions?	Rule
Buy Medigap in your first 6 months when you're both 65 and in Part B	No	Federal Medigap open enrollment
Buy Medigap under 65 with Medicare because of a disability or ESRD, within 6 months of Part B	No	Fla. Stat. 627.6741(1)(a)1
Buy Medigap within 2 months after group health coverage ends	No	Fla. Stat. 627.6741(1)(a)2
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 at 65 (trial right)	No	Federal guaranteed issue
Your Medicare Advantage plan ends, or you permanently move out of its area	No, for certain plans, including A, B, D and G (C or F if first eligible before 2020)	Federal guaranteed issue; apply up to 63 days after coverage ends

In short: in Florida it's easier to start with Medigap and move to Medicare Advantage later than the other way around. A new Medigap policy can be returned within 30 days for a full refund (Fla. Stat. 627.674). If your Medicare Advantage plan is ending for 2027, this may be your chance to buy Medigap without health questions; see Florida plans ending in 2027.

Which fits your pattern?

You see doctors regularly in both states: Original Medicare with Medigap avoids network and time limits. Add a Part D plan with pharmacies in both places.
You get almost all routine care at your permanent home and are away less than 6 months: a Medicare Advantage plan can work, since emergencies and urgent care are covered anywhere in the U.S.
You're away 6 to 12 months: Medicare Advantage only works with a plan whose visitor or traveler program covers where you go. Ask before you enroll.
You're thinking about making Florida permanent: settle that first. Your plan choices come from your permanent county. See moving to Florida with Medicare.

How to decide

List your doctors, hospitals and pharmacies in both places. Note which ones you see for ongoing care.
Count your months away. Compare them to the 6-month rule and any visitor program.
Check Medigap timing. If you're in your first Medigap open enrollment, or have a guaranteed-issue or Florida group-coverage window, that's when Medigap is easiest to buy.
Compare during Open Enrollment, October 15 to December 7. See snowbirds and Medicare and our snowbird checklist.

To compare Medicare Advantage plans and Medigap policies from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code.

Frequently asked questions

Should snowbirds choose Medicare Advantage or Medigap?

Neither is right for everyone. Original Medicare with Medigap suits snowbirds who want to see doctors in both states without network or time limits. Medicare Advantage can work if the plan's network or visitor program covers both places, or if you get only emergency and urgent care away from home.

Can a Medicare Advantage plan cover me in two states?

Some can. A PPO may pay for out-of-network care at a higher cost, and a plan may offer an optional visitor or traveler program that covers you outside its area within the U.S. for up to less than 12 months. Ask the plan which areas and providers it covers.

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

You can return to Original Medicare during Open Enrollment or the January to March Medicare Advantage 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.

Do I need a Part D plan with Medigap as a snowbird?

Usually yes, because Medigap doesn't cover prescriptions. Choose a standalone Part D plan with network pharmacies near both homes. CMS lists 11 standalone Part D plans in Florida for 2027.
