Do Medicare Advantage plans work when I travel out of state?

Emergencies are covered anywhere. Routine care usually is not. Here is what that means for snowbirds, travelers and anyone crossing into Mexico.

Advantage plans are built around a local service area, which is exactly how they keep costs down. When you leave that area, what is covered changes.

What is always covered, anywhere in the country

• Emergency care
• Urgently needed care when you cannot reasonably get to an in network provider
• Dialysis while temporarily out of the area

Never delay going to an emergency room because you are out of your area. That is covered, and hesitating is the actual danger.

What usually is not

• Routine doctor visits
• Follow up care after an emergency, once you are stable
• Scheduled procedures and elective surgery
• Ongoing management of a chronic condition
• Prescription refills outside the plan's pharmacy network, which may cost more or not be covered

On an HMO, out of network routine care is typically not covered at all. On a PPO it is covered at a higher cost share. See the HMO and PPO comparison.

If you spend months away

This is where it gets serious rather than inconvenient. Most Advantage plans require you to live in the service area, and extended absence can affect your eligibility. Many plans allow a continuous absence of up to six months before disenrollment becomes an issue, but the rules vary by plan.

• Tell the plan about extended travel rather than hoping it goes unnoticed.
• Ask specifically about the visitor or traveler benefit, which some plans offer for stays away from home.
• If you regularly spend half the year elsewhere, consider whether Original Medicare with a supplement fits your life better. It works identically in all fifty states with no network at all.

Travel into Mexico

This matters here more than almost anywhere else in the country.

Original Medicare generally does not cover care outside the United States, with narrow exceptions. Advantage plans are not required to cover foreign care either, though some include a limited emergency benefit abroad.

If you cross regularly or spend extended time in Mexico, ask the plan directly what it covers outside the country and get the answer in writing. Do not assume, and do not rely on what a neighbor tells you their plan does.

Before any significant trip

1. Ask the plan what is covered where you are going, in writing.
2. Find out whether the plan has a national network you can use, which some carriers do.
3. Get prescriptions filled before you go, or confirm the pharmacy network reaches your destination.
4. Carry your plan card and know the number for the plan's nurse line and prior authorization desk.
5. For travel outside the country, price a travel medical policy. They are inexpensive and they cover the gap.
