The roaming retiree
Mostly abroad.
Different Medicare rules.
You're not splitting your time — you're mostly abroad, spending a couple of months in the US each year to anchor your domicile, see family, and handle logistics. That's a different situation from a snowbird, and it requires a different Medicare setup.
The 6-month Medicare Advantage rule isn't a risk you have to manage. At 8–10 months abroad it's a mathematical certainty — and the coverage decisions that follow from that are different enough to warrant their own page.

Four rules that change at 8 months.
If you're spending 8–10 months a year abroad — here's what's different from the snowbird situation:
- Medicare Advantage will disenroll you — 8–10 months abroad crosses the 6-month threshold every year. It's not a risk to avoid; it's a certainty to plan around.
- Keep Part B — dropping it locks in a permanent 10%-per-year penalty. The math almost never favors dropping it for full-time travelers.
- Original Medicare + Medigap Plan G handles your US visits — switch off Advantage before your first long trip, on your schedule, not the plan's.
- You need a full annual IPMI plan for abroad — not travel insurance, not a short-term plan. International Private Medical Insurance is your actual health plan for most of the year.
Medicare Advantage will disenroll you.
Plan around it.
For snowbirds, the 6-month service area rule is a trap — something that catches people who don't realize they're close. At 8–10 months abroad, it's a certainty you cross every year. The fix is the same, but the urgency is higher.
Auto-disenrollment, every year
Most Medicare Advantage plans require you to live in their service area — for most plans, the US. More than 6 months continuously outside that area and the plan can auto-disenroll you. You get a Special Enrollment Period to switch back to Original Medicare, but on the plan's timeline, not yours.
Switch before it happens
None of the problems below happen if you switch to Original Medicare during open enrollment, on your schedule, before your first extended trip. The Annual Enrollment Period runs October 15–December 7 each year. Do this the fall before you start traveling.
The Medigap problem after auto-disenrollment.
When you were originally on Medicare Advantage, you may have given up your Medigap guaranteed issue rights. After auto-disenrollment, you get a short window (typically 63 days) to buy Medigap — but depending on your state and when the disenrollment happens, insurers may be able to use medical underwriting. That means higher premiums, or outright denial, based on your health history.
Switching proactively — while you're healthy, on your terms — closes this risk completely.
Four layers. One job each.
The setup is similar to a snowbird's, with one significant difference: the international insurance layer. Snowbirds can often use shorter-term plans for their 3–6 months abroad. You need a full annual plan.
Keep it — always
Free for most people. Covers US hospital stays during your visits home. No reason to touch it.
Keep it — even at 2–3 months home
The $202.90/month premium (2026) feels wasteful when you're rarely in the US. But dropping Part B locks in a permanent 10%-per-year late enrollment penalty on any future re-enrollment. If there's any realistic chance of returning for US care — and for most perpetual travelers there is — keeping Part B is almost always the right call.
Your US-visit coverage
Medigap Plan G fills the 20% gap Original Medicare leaves on US care. Its foreign travel emergency benefit (80% up to $50,000 lifetime) is technically available abroad — but it's a backstop, not your primary abroad coverage. Its real job for perpetual travelers is covering US care during your annual visits home. Buy it before you switch off Advantage, while your options are fully open.
Full Medigap guide for expats →Your actual health plan abroad
For your 8–10 months abroad, you need a full International Private Medical Insurance policy — GP visits, specialist care, inpatient stays, chronic condition management, and prescriptions. This isn't travel insurance. Your IPMI plan is your real health plan for most of the year. Look for: no age cutoffs at 70 or 75, direct billing in the countries you frequent, and clear terms on pre-existing conditions upfront.

Snowbird (3–6 months abroad)
MA disenrollment is a risk to avoid. Shorter-term international plans work for abroad months. Medigap Plan G's foreign emergency benefit provides real backstop value abroad.
Perpetual traveler (8–10 months abroad)
MA disenrollment is certain — plan around it, don't try to avoid it. A full annual IPMI plan is required. Medigap's primary job is US care; IPMI handles abroad.
Five things to do before your first extended trip.
The retirees who handle this smoothly do it in the fall before the first year of full-time travel — not after a plan disenrolls them abroad.
Advantage or Original Medicare?
Check your Medicare card and plan documents. If you're on a Part C Advantage plan, you need to switch — not because the 6-month rule is a risk, but because it's a certainty you need to get ahead of.
Switch during Annual Enrollment
Coverage starts January 1. If you have a qualifying Special Enrollment Period, you may be able to move outside this window. Do this the fall before your first extended trip abroad.
Apply for Medigap Plan G
When leaving a Medicare Advantage plan you may have a guaranteed issue window — typically 63 days, and it doesn't apply to every plan type in every state. Apply while you're healthy, on your schedule. Don't rely on the window.
Get an annual IPMI plan
Don't confuse this with travel insurance. Compare annual IPMI plans with inpatient and outpatient coverage, direct billing in the countries you'll spend time in, and no age cutoffs in your 70s. Some plans have waiting periods — get quotes before you go.
Decide what to do with Part D
If your IPMI plan covers prescriptions abroad and you fill most medications overseas, Part D may feel redundant. But the penalty accrues at 1% per month — confirm your IPMI plan qualifies as creditable coverage before you drop it.
Common Questions
How is this different from the snowbird situation?
My Medicare Advantage plan will disenroll me anyway — why not just let that happen?
What's the difference between an IPMI plan and a travel insurance plan?
Do I still need Part B if I'm almost never in the US?
What does Medigap Plan G actually cover when I'm traveling?
What about Part D — do I still need prescription drug coverage?

Four things to do, in this order.

Switch off Medicare Advantage during Annual Enrollment
October 15–December 7, coverage starts January 1. Do this the fall before your first extended trip — before the 6-month rule catches you.
-
Apply for Medigap Plan G while you still can
This is the most time-sensitive step. Apply while you're healthy, on your schedule. Don't rely on a post-disenrollment guaranteed issue window.

Sort your tax residency and domicile
Full-time travel raises questions your snowbird neighbors don't face: which state is your domicile, where do you file, and does your travel pattern trigger foreign tax obligations? Get this sorted before you go.

Tracking your Schengen days?
Managing time abroad as a perpetual traveler means keeping a close eye on the Schengen 90/180 rule — the immigration limit that determines how long you can stay in Europe. Our free Schengen day counter shows how many days you've used in the trailing 180-day window and when you can legally re-enter.
