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.

The 60-second version

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.
Section 01 · The core problem

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.

What happens

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.

Why not wait

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.

Section 02 · The right setup

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.

Part A

Keep it — always

Free for most people. Covers US hospital stays during your visits home. No reason to touch it.

Part B

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.

Medigap Plan G

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.

Annual IPMI Plan

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.

How this differs from the snowbird setup.

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.

Section 03 · Before you go

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.

Confirm your plan type

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.

October 15 – December 7

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.

Most time-sensitive step

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.

Before you leave

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.

Check before dropping

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.

FAQ

Common Questions

How is this different from the snowbird situation?
Scale. A snowbird spends 3–6 months abroad and may or may not cross the Medicare Advantage 6-month threshold depending on their specific plan and dates. A perpetual traveler spends 8–10 months abroad — they will cross it, every year, without question. The coverage solution is also different: snowbirds can often get by with a shorter-term international plan for their abroad months. Perpetual travelers need a full annual International Private Medical Insurance (IPMI) policy, because their abroad months are most of the year.
My Medicare Advantage plan will disenroll me anyway — why not just let that happen?
Because the timing and the Medigap situation won't be in your favor. When auto-disenrollment happens, you get a Special Enrollment Period to return to Original Medicare — but it's the plan's timeline, not yours. More critically: Medigap. If you originally enrolled in Medicare Advantage after your initial open enrollment window, you may have already given up your guaranteed issue rights. When you try to buy Medigap after being disenrolled, insurers in most states can use medical underwriting — which means higher premiums or outright denial based on your health history. Switching proactively, on your schedule, while you're still healthy, avoids all of this.
What's the difference between an IPMI plan and a travel insurance plan?
Travel insurance is designed for emergencies during short trips. It typically covers emergency evacuation and acute care — not chronic condition management, routine GP visits, specialist referrals, or prescription refills. International Private Medical Insurance (IPMI) is a full health plan: inpatient and outpatient care, specialist visits, ongoing prescriptions, mental health, preventive care, and more. For a retiree spending most of the year abroad, travel insurance isn't a substitute. You need a plan that functions as your actual health plan, not emergency-only coverage.
Do I still need Part B if I'm almost never in the US?
Almost certainly yes. Keep Part B. Dropping it to avoid the $202.90/month premium (2026 rate) triggers a permanent 10%-per-year late enrollment penalty on any future re-enrollment. If you ever return to the US — for family reasons, a health crisis, anything — you'd re-enroll at a significantly higher rate, permanently. The break-even for dropping Part B only makes sense for people making a genuine permanent move with no realistic return scenario. Full-time travelers almost always have some realistic chance of returning, even years from now.
What does Medigap Plan G actually cover when I'm traveling?
Medigap Plan G includes a foreign travel emergency benefit: 80% of covered emergency care costs after a $250 calendar-year deductible, up to $50,000 lifetime. It only applies to emergencies, and only in the first 60 days of a trip. For a perpetual traveler, this isn't your primary abroad coverage — your annual IPMI plan handles that. Think of Medigap's foreign emergency benefit as a backstop for the months you're back in the US, not as abroad health coverage. Its real value for perpetual travelers is filling Original Medicare's 20% gap on US care.
What about Part D — do I still need prescription drug coverage?
It depends on your prescriptions. If you fill most or all of your medications abroad (which many perpetual travelers do — costs are often lower), you may have limited use for US-specific Part D coverage. But the late enrollment penalty applies here too: 1% per month (12% per year, compounding) for every month without creditable drug coverage after becoming eligible. If there's any meaningful chance you'll need Part D in the future, maintaining it is usually cheaper than restarting with a penalty. Many IPMI plans include outpatient prescription coverage for abroad — check whether that counts as creditable coverage before dropping Part D.
When should I make the switch from Medicare Advantage to Original Medicare?
Before your first extended trip. The Annual Enrollment Period runs October 15–December 7, with coverage starting January 1. That's the standard window. If you have a qualifying Special Enrollment Period (moving, losing other coverage), you may be able to switch outside that window. The key point: switch while you're still home, before you've triggered the 6-month rule, and while you still have your best Medigap options. The moment you're auto-disenrolled abroad, your options narrow.
Your next step

Four things to do, in this order.

  1. 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.

  2. 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.

  4. 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.
