For most people, the quick answer is that Medicare does not cover routine care during foreign travel. Original Medicare, Part A and Part B, usually pays only within the United States and its territories.
It has a few narrow exceptions, such as an emergency in Canada while traveling directly between Alaska and another state, or when a foreign hospital is closer than a U.S. hospital in limited circumstances. So, what Medicare plans cover foreign travel more broadly? A Medicare Supplement (Medigap) policy can be the most dependable option for emergency medical care abroad.
Several standardized Medigap plans include a foreign travel emergency benefit, typically paying 80% of covered emergency costs after a deductible, up to a lifetime limit. It is not comprehensive international travel insurance, but it can substantially reduce exposure to an unexpected hospital bill.
Medicare Advantage plans may include emergency coverage outside the U.S., though benefits, copays, limits, and authorization rules vary by plan. Check the Evidence of Coverage before you leave, not just the plan’s marketing summary.
Stand-alone Part D drug plans generally do not add overseas medical coverage. For extended international travel, compare your Medicare coverage with a dedicated travel medical policy, especially for evacuation, trip interruption, and care that is not an emergency.
