Does Medigap cover me when I travel or move to another state?

A supplement works in every state with no network, and it moves with you. What the foreign travel benefit pays, and where it stops.

Key points

A Medigap policy, the supplement that pays your share of Original Medicare bills, works in every state with any doctor who takes Medicare.
Moving does not change it, but a standalone drug plan has a service area, so a move usually means a new one.
The foreign travel emergency benefit covers only the first 60 days of a trip, and it stops at a lifetime maximum.

Yes. Your Medigap policy, the supplement that pays your share of Original Medicare bills, works everywhere in the United States with any doctor who takes Medicare. There is no network, the list of doctors a plan contracts with, and no service area. That is the main practical difference from a Medicare Advantage plan.

Traveling inside the country

Your coverage works the same way in every state. Routine care, specialists, scheduled procedures, emergencies. You do not have to tell anyone you are traveling, or look for a doctor inside a network.

An Advantage plan works differently. Emergencies are covered anywhere, but routine care away from home generally is not. See how Advantage plans handle travel.

Moving to another state

Your policy moves with you. You do not have to change plans or apply again. You also do not go through underwriting, which means a company reading your health history and deciding whether to take you.

Two things are still worth doing.

Tell your carrier your new address. The premium, the monthly bill for the coverage, varies by ZIP code, so yours may move either way.
If you have a standalone Part D plan, a drug plan you buy on its own, that one does have a service area. Moving opens a special enrollment period, a window to switch outside the usual dates, and you will likely need a new drug plan.

The supplement follows you anywhere, but the drug plan does not. Take care of the Part D side inside your special enrollment window after a move.

Foreign travel emergency coverage

Original Medicare generally does not pay for care outside the United States. Several Medigap plan letters include a foreign travel emergency benefit. It is usually built this way.

Emergency care only, and only during the first 60 days of a trip.
A separate deductible, an amount you pay yourself, before the benefit pays anything.
Then it pays a share of approved costs, commonly 80 percent.
It stops at a lifetime maximum, commonly a modest amount.

The coverage is real, and it is limited. On $10,000 of approved emergency care, 80 percent is $8,000, and the rest is yours. A serious event overseas, especially one needing an air evacuation, can pass the lifetime maximum quickly.

Travel into Mexico

This matters more in South Texas than in most of the country. The benefit does apply, under the same limits: emergency only, the first 60 days, the deductible, the percentage, the cap.

It does not cover routine or planned care across the border. If you cross often, or stay in Mexico for long stretches, a separate travel medical policy is inexpensive and covers that gap.

Before a significant trip

Check whether your plan letter includes foreign travel emergency coverage, and what the lifetime maximum is.
For a trip abroad, price a travel medical policy that includes emergency evacuation. Evacuation is the costly part, and the Medigap benefit will not stretch to cover it.
For travel inside the country, do nothing. You are already covered.
Carry both cards. You should not have to file claims yourself.

Before a trip abroad, check your plan letter and price a travel medical policy. See what Medigap does not cover. Call our McAllen office at (956) 687 3334 to go through your own policy, or enter your ZIP code in the plan pricing box on this page.

Common follow-up questions

Do I need to change my supplement if I move to another state?

No. It works nationwide with any doctor who takes Medicare. Tell your carrier your new address, since the premium can vary by ZIP code.

Does Medigap cover me in Mexico?

Several plan letters include an emergency benefit abroad, limited to the first 60 days of a trip, with a deductible and a lifetime maximum. Routine care is not covered.

What happens to my drug plan if I move?

Part D plans have service areas. Moving opens a special enrollment period, and you will likely need a different drug plan.
