Medicare for Snowbirds: How to Stay Covered in Two States

Millions of retirees spend their winters in warmer states, Florida, Arizona, Texas, the Carolinas, and return north for the spring and summer. This lifestyle, often called snowbirding, is genuinely wonderful except for one thing: Medicare coverage does not follow you as cleanly as you might assume. Whether you can see a doctor in your winter state, what you pay, and whether your plan considers you out of network depends entirely on which type of Medicare coverage you have. Getting this wrong can mean paying full price for care, or being denied routine services entirely, hundreds of miles from home.

Bryce's Take

The snowbird coverage question is one I help a lot of Florida-bound retirees think through. If you are spending five or six months in Florida each year, an HMO plan centered in another state is essentially phantom coverage for half the year. Original Medicare plus Medigap solves this problem completely. The premium is higher, but you are never out of network anywhere in the country.

Original Medicare: the snowbird's friend

Original Medicare Parts A and B work at any Medicare-accepting provider anywhere in the United States, year-round, with no network distinctions, no out-of-state surcharges, and no prior notice required. If you see a Medicare-accepting physician in Florida in January and the same Medicare-accepting physician in Michigan in June, your coverage, cost-sharing, and access are identical in both states. This is the defining advantage of Original Medicare for people who live in multiple locations. Your Medicare card is essentially a nationwide insurance card accepted by 97% of physicians in every state.

Medigap: follows you wherever Medicare goes

Medigap supplement plans also cover you in both states without distinction. Since Medigap fills the gaps in Original Medicare, and Original Medicare works nationwide, your Medigap coverage works nationwide as well. A Plan G purchased in Michigan covers your 20% coinsurance in Florida during winter just as it does in Michigan during summer. There are no out-of-network concerns, no plan service area restrictions, and no need to notify your Medigap insurer that you will be in another state. This combination, Original Medicare plus Medigap, is the cleanest solution for snowbird coverage.

Medicare Advantage: the service area problem

Medicare Advantage plans are built around service areas, specific counties or regions where the plan has contracted providers. HMO plans generally cover non-emergency care only within that service area. PPO plans allow out-of-network care at higher cost-sharing but still have preferred in-network regions. If you enrolled in a Michigan Medicare Advantage HMO and spend five months in Florida each year, you are outside your plan's service area for nearly half the year. Routine doctor visits, prescription pickups (if the plan's preferred pharmacy network differs), specialist visits, and non-emergency care in Florida may be covered only at higher out-of-network rates or not covered at all under the HMO structure.

When Advantage does and does not cover you out-of-area

All Medicare Advantage plans are required to cover emergency care anywhere in the United States at in-network cost-sharing rates. Urgently needed care, care you need for a condition that would worsen without prompt treatment, must also be covered. But the definition of urgently needed care does not stretch to include routine care simply because you are out of state. A quarterly visit to your cardiologist in Florida is not urgently needed care under your Michigan Advantage plan. If you need that cardiologist visit, either pay out-of-pocket, use out-of-network PPO benefits if available, or establish care with an in-network provider in your winter state under a new Advantage plan.

Solutions for Advantage enrollees who snowbird

If you are enrolled in Medicare Advantage and spend significant time out-of-state, you have several options. Some Medicare Advantage plans, particularly PPO plans, have national networks with contracted providers in multiple states. Verify whether your plan has contracted providers in your winter location. Some national MA plan carriers like UnitedHealthcare, Humana, and Aetna have contracts with large physician groups in many states. Alternatively, consider switching to Original Medicare plus Medigap, which eliminates the service area problem entirely. The trade-off is typically a higher monthly premium and losing Advantage extras like dental and vision.

Part D pharmacy access in two states

If your Part D plan uses a preferred pharmacy network, verify that a preferred pharmacy is accessible in both your summer and winter locations. Most major pharmacy chains (CVS, Walgreens, Rite Aid, and major grocery pharmacies) are in most Part D preferred networks nationwide, so this is rarely a significant issue. If you use an independent local pharmacy, verify its network status in both states. Mail-order pharmacy with a 90-day supply avoids the geographic pharmacy issue entirely.
