Medicare for Snowbirds: Staying Covered in Two States

Retired couple checking Medicare cards in Arizona

If you spend winters in Arizona, California or Florida and summers in Central Oregon, the simplest setup is Original Medicare paired with a Medigap (Medicare Supplement) plan and a stand-alone Part D drug plan. That combination lets you see any doctor or hospital in the country that accepts Medicare, so a second address doesn’t mean a second set of rules. Medicare Advantage can work too, but only if its network follows you. This guide explains how to tell the difference, what to check before you pack the car, and where the real surprises hide.

TL;DR

  • Medicare has no “snowbird plan.” Original Medicare plus Medigap is the most portable option across states, because you aren’t tied to a local network.
  • Medicare Advantage plans are built around service areas and networks. Non-emergency care away from home can cost much more or not be covered, so confirm exactly how a plan treats you in your winter state.
  • Medicare generally doesn’t cover care outside the U.S. Some Medigap plans give limited emergency coverage abroad, so a Mexico, Canada or Europe winter needs its own plan.
  • Oregon’s Birthday Rule lets many Medigap holders shop for a lower price each year without health questions. Time it around your birthday, not your travel dates.

What “snowbird” means to Medicare

Medicare doesn’t use the word. It sees a beneficiary with a permanent address, the one you give Social Security and your plan, and a set of rules that depend on which type of coverage you chose. For a Bend resident who drives to Yuma or Palm Springs in November, the question is never “where am I today?” It is “does my plan pay for care in the place I’m standing?”

That answer depends almost entirely on whether you have Original Medicare (Parts A and B) or a Medicare Advantage plan (Part C). The two behave very differently once you cross a state line. Medicare’s own explanation of how to get services shows the difference at the first step: with Original Medicare you show your Medicare card, while with a private plan you show the card issued by that plan.

Original Medicare plus Medigap: the portable option

Original Medicare is a federal program, not a regional one. If a doctor or hospital in Arizona accepts Medicare, you can use them with the same card you use at home in Bend. There are no networks to check and no referral to get from a doctor back in Oregon.

Medigap sits on top of that. It pays some or all of the costs Original Medicare leaves to you, such as deductibles and coinsurance, and the standardized plan letters mean a Plan G is a Plan G whether you buy it in Oregon or use it in Florida. That predictability is why so many people who split the year choose it. You can read how the plans compare on our Medicare Supplement (Medigap) plans page.

What you give up is monthly cost certainty. Medigap premiums are paid on top of your Part B premium, which is $202.90 a month in 2026 with a $283 annual deductible for most people. Higher earners pay an income-related surcharge. We break down the numbers in our guides to the 2026 Part B premium and IRMAA brackets.

Where Original Medicare still has gaps

Portability doesn’t mean everything is covered. Two gaps matter for people who travel a lot:

  1. The three-night rule. Original Medicare covers a skilled nursing facility stay after a hospital stay only if you were admitted as an inpatient for three consecutive days, not counting the day you leave. Medicare’s skilled nursing facility page is explicit that time in observation status doesn’t count, even if you stay overnight. If you land in a hospital far from home, ask every day whether you’re an inpatient or under observation.
  2. No coverage outside the U.S. More on that below.

Medicare Advantage: when the network is the problem

Medicare Advantage plans replace Original Medicare with a private plan that must cover the same basic benefits but can set its own rules, including provider networks. The SHIBA-affiliated SHIP Medicare Minute handout puts it plainly: these plans must provide the same benefits as Original Medicare but can have different rules, like provider networks.

For a snowbird, that is the whole issue. Advantage plans are generally tied to service areas, and people who choose them for extras like dental or vision often find that non-emergency care outside their home network costs far more or isn’t available. Emergency and urgent care are usually handled differently from routine care, but “usually” is not a guarantee, so read your plan’s evidence of coverage rather than relying on a sales call.

Some Advantage plans, particularly PPOs, have wider or multi-state networks. If you like the extra benefits and the lower premium, it is reasonable to consider one, as long as you check these items for both places you live:

  • Are your regular doctors and the nearest hospital in the network in your winter town?
  • What will you pay for a routine visit, a specialist and an out-of-network visit there?
  • Is there a limit on how long you can be away from the service area?
  • Does the plan’s pharmacy network cover a store near each address?

There is one trade-off in the other direction. Some Advantage plans waive the three-night rule that Original Medicare enforces, according to the same skilled nursing facility guidance. That can be a real benefit. It rarely outweighs a network that doesn’t reach your winter home, but it belongs on the list.

Side-by-side: which fits a two-state year?

Original Medicare + Medigap + Part D Medicare Advantage (with drug coverage)
Doctors and hospitals Any that accepts Medicare, nationwide Depends on plan network and service area
Routine care in your winter state Same as at home May cost more, or may not be covered
Monthly cost Part B plus Medigap plus Part D premiums Part B plus a plan premium, often lower
Extras such as dental and vision Not included; buy separately Often included
Three-night rule for nursing facility care Applies Some plans waive it
Best for People who want one set of rules in every state People whose plan network reaches both homes

Neither is right for everyone. A healthy 66-year-old who winters near a major city covered by a broad PPO may be well served by Advantage. Someone with a cardiologist in Bend and a heart condition that could flare in Arizona will usually sleep better with Medigap.

Prescriptions in two places

Part D is where plenty of snowbirds get tripped up, because pharmacies are not interchangeable. Before you leave, check three things with your plan:

  • Whether a pharmacy near your winter address is in the network and at what copay tier.
  • Whether the plan offers mail order, and whether it can ship to a second address.
  • Whether you can get an early or extended refill before you travel. Rules vary by plan and medication, so ask rather than assume.

It’s also worth checking that your drugs are on the plan’s formulary every October, because plans change each year. That’s one reason we like an annual look at your coverage, which is what our annual Medicare plan reviews are for.

If your winter is outside the U.S.

Mexico, Canada and Europe are common snowbird destinations, and this is where the biggest misunderstanding lives. Medicare usually doesn’t cover health care outside the U.S., with a few narrow exceptions. “Outside the U.S.” means anywhere other than the 50 states, Washington D.C. and the U.S. territories.

Certain Medigap plans (C, D, F, G, M and N) provide emergency care while traveling abroad, but with limits: a $250 annual deductible, 80% coverage, and a $50,000 lifetime cap, and it applies only to trips whose first 60 days of travel fall within certain rules. Medicare Advantage plans generally don’t cover foreign care unless they list specific extra emergency benefits. A winter-long stay in another country is a different matter from a two-week trip, because those 60-day limits on each trip are easy to exceed.

Medigap emergency travel coverage limits

So if you plan to spend months abroad, treat Medicare as unavailable for routine care and buy a separate travel medical policy that matches the length of your stay, including medical evacuation. We walk through the questions to ask in how to confirm Medicare’s foreign travel coverage.

The Oregon Birthday Rule: shop your Medigap while you’re away

Many of the people who contact us are paying more for Medigap than they need to. Oregon has a consumer protection built for exactly that. Under the Birthday Rule, you can switch to a different company’s Medigap policy during a 60-day window that starts 30 days before your birthday and ends 30 days after. You must keep the same plan type or pick one with lesser benefits. Acceptance is guaranteed regardless of your health, and coverage typically starts on the first of the month after you apply. It applies only to Medigap policies issued after January 1, 1990, and excludes self-funded employer group plans.

For snowbirds, the practical points are these:

  • Plan the window around your travel. If your birthday falls in January and you’re in Arizona, you can still apply remotely. Put the dates on the calendar before you leave.
  • Don’t cancel the old policy early. Wait until the new one is formally issued. Paying two premiums for a month is common and far cheaper than a gap in coverage.
  • Watch high-deductible Plan F. Oregon’s Birthday Rule fact sheet notes that moving from one high-deductible Plan F to another restarts the deductible under the new carrier.

We cover the window step by step in our posts on the Oregon Birthday Rule in Central Oregon and how to switch Medigap plans during the 60 days. If you’re newly eligible, a different timeline applies, covered in choosing a Medigap plan during open enrollment.

A pre-departure checklist

  1. Confirm your mailing address is current with Social Security, your Medigap carrier and your Part D or Advantage plan.
  2. Carry your red, white and blue Medicare card and your Medigap and Part D cards.
  3. Ask your Part D plan about a pharmacy near your winter address, mail order and early refills.
  4. If you have Advantage, call the plan and ask for written confirmation of what is covered in your winter state and for how long.
  5. Identify a nearby urgent care and hospital that accept your coverage before you need one.
  6. Going abroad? Price a travel medical policy that covers the whole trip and evacuation.
  7. Note your birthday window and your annual enrollment dates for next year.

If cost is a concern, you may also qualify for help. Medicare Savings Programs are run by your state and can pay Part A and Part B premiums for people who meet income limits. Because you’re a resident of one state, the state where you have your permanent address is the one to ask.

Our perspective: what we tell Bend snowbirds

We’re a local agency in Bend, and the most common mistake we see is buying coverage based on where you spend the summer. Someone picks an Advantage plan because it looks inexpensive and includes dental, and then learns in January that their doctor visit in a winter town sits outside the network. We would rather you hear that from us before you enroll than from a bill.

Our approach is education first. We don’t push a plan. We ask where you spend your time, which doctors you want to keep, which medications you take and how much cost uncertainty you can live with, and then we lay out Original Medicare with Medigap and Advantage side by side. Sometimes the answer is Medigap. Sometimes a PPO with a wide network suits a healthy person who winters in one place. Either way, you leave the conversation understanding your deadlines and your options, with no call-center script and no pressure. If you have a Medigap plan that has crept up in price, the Birthday Rule is the first thing we check.

FAQ

Does Medicare cover me in Arizona or Florida if I live in Oregon?

Original Medicare does, because it works nationwide with any provider who accepts Medicare. With a Medigap plan on top, your supplemental coverage follows you too. Medicare Advantage depends on the plan’s network and service area, so check before you leave.

Can I keep my Oregon Medigap plan if I spend winters elsewhere?

Yes. Medigap plans are standardized and not tied to a local network. Keep your permanent address current with your carrier and Social Security, and tell us if you plan to move your permanent residence, because that can change your options.

Does Medicare cover me on a winter trip to Mexico or Canada?

Usually not. Medicare generally doesn’t pay for care outside the 50 states, D.C. and the U.S. territories. Some Medigap plans offer limited emergency coverage abroad, so a separate travel medical policy is the safer choice for a long stay.

What is the three-night rule, and why does it matter when I travel?

Original Medicare covers skilled nursing facility care only after at least three consecutive days as an inpatient, and observation time doesn’t count. If you’re hospitalized away from home, ask staff each day whether you’re admitted or under observation, since it affects your rehab coverage.

When can I switch my Medigap plan to pay less?

In Oregon, the Birthday Rule gives you a 60-day window around your birthday to move to another company’s policy of the same or lesser plan type without health questions. Mark it on your calendar before you leave for the winter and keep your old policy until the new one is issued.
