Moving to Florida on Medicare: what changes, and the enrollment window you don't want to miss

First, the part that doesn't change

If you have Original Medicare (Part A and Part B), that coverage travels with you. Parts A and B work the same in every state, so you don't re-enroll in basic Medicare just because you crossed a state line. What can change is everything built on top of Original Medicare — your Advantage plan, your drug plan, and in some cases your supplement.

What changes: Advantage and Part D are local

Medicare Advantage (Part C) and Part D prescription drug plans are built around a specific service area — usually your county. Plans, provider networks, and drug formularies are all local. So an Advantage or Part D plan you had up north almost certainly won't cover routine care the same way once you're a Florida resident. Moving is exactly the kind of event Medicare planned for: it triggers a Special Enrollment Period (SEP) so you can switch to a plan that works where you now live.

The move SEP has a specific shape worth memorizing:

• If you tell your current plan before you move, your window to switch starts the month before your move and runs for two full months after you move.
• If you tell your plan after you've moved, the window starts the month you notify them and runs for two full months after that.

Either way, you get a defined stretch — not forever. The cleanest approach is to line up your Florida plan choice around your move date rather than waiting until you're unpacked and the clock is already running.

The Florida wrinkle: Medigap here is different

This is where Florida trips people up, and where getting it right matters most.

Medicare Supplement (Medigap) plans are standardized and generally "portable" — a Plan G is a Plan G, and it keeps paying wherever you live. If you already have a Medigap policy, you usually don't need a new one just because you moved; you may just want to review the premium, since Florida pricing can run higher than what you paid elsewhere.

But two Florida realities change the math if you're thinking about getting or switching a Medigap plan after your move:

1. Florida has no Medigap "birthday rule." Some states (California is one) give you an annual window to switch Medigap plans without health questions. Florida does not. Outside of protected windows, Florida Medigap is medically underwritten — meaning an insurer can review your health history and, in some cases, decline you or charge more. The full explainer is on the Florida Medicare Supplement (Medigap) page.
2. Because of that, a move-related guaranteed-issue window can be valuable — but it's conditional. Certain moving situations (for example, losing your Medicare Advantage plan because you've left its service area) can open a limited guaranteed-issue right to buy specific Medigap plans without underwriting. A plain move doesn't automatically grant that in every case, so it's worth confirming whether your specific situation qualifies before the window closes. Miss it, and you may be back to underwriting — where approval isn't guaranteed.

In plain terms: in Florida, timing a Medigap decision is not something to leave to chance. If a protected window applies to you, using it is often far easier than trying to qualify medically later.

If you split the year: the snowbird question

Plenty of Florida newcomers keep a home up north and spend part of the year there. That's a real coverage-design question, not an afterthought — an Advantage plan tied to a Florida county may not travel well, while Original Medicare plus a Medigap plan usually does. There's a full walkthrough on the Medicare for snowbirds page, and it's the kind of thing worth talking through before you commit, so a plan that's perfect in Sarasota doesn't leave a gap in July.

Your move checklist, in order

1. Confirm your official move date. Your SEP timing keys off it.
2. Tell your current Advantage or Part D plan — ideally before you move — so your switch window opens on the early end.
3. Check your prescriptions and doctors against Florida plans. Formularies and networks are county-specific here; the plan that fit up north may not fit your new ZIP.
4. Review your Medigap situation if you have one, and — if you're getting or switching Medigap — find out whether a protected, no-underwriting window applies to you before it closes.
5. Make your changes while the window is open. Once you know what applies, enroll or switch; don't let the two-month clock run out.

You can do all of this yourself through Medicare.gov or 1-800-MEDICARE, and Florida has free, impartial counseling through SHINE (Serving Health Insurance Needs of Elders) at 1-800-963-5337 or floridashine.org. If you'd rather have someone walk your specific plans, counties, and timing with you, that's what I do — at no cost to you. Start with how it works or the plan basics, and reach out any time.
