Does Medicare Work in Mexico? Coverage Rules for US Retirees
What Medicare pays for south of the border, what Medigap and Medicare Advantage add, and the penalty math behind keeping or dropping Part B while you live in Mexico City.
Original Medicare generally does not pay for health care in Mexico. It covers foreign hospital care only in three narrow situations, mostly involving emergencies near the US border, and it never pays for drugs bought abroad. Most Medigap plans add a foreign travel emergency benefit that pays 80% after a $250 yearly deductible, up to $50,000 in a lifetime, as of November 2026.
Does Medicare cover care in Mexico?
In most situations, no. Medicare’s April 2026 fact sheet on coverage outside the United States says Medicare won’t pay for health care or supplies you get outside the US, and “outside the US” includes Mexico. If your situation does not fit one of the exceptions, you pay the full cost to the doctor or hospital.
The fact sheet lists three situations in which Medicare may pay for care in a foreign hospital:
- You are in the US when a medical emergency happens, and the foreign hospital is closer than the nearest US hospital that can treat you.
- You are traveling through Canada by the most direct route between Alaska and another state when an emergency happens, and the Canadian hospital is closer.
- You live in the US and the foreign hospital is closer to your home than the nearest US hospital that can treat you, emergency or not.
None of these applies to someone living in Mexico City. The first and third can apply to people who live in US border towns and use a hospital on the Mexican side.
What does Medicare pay for when an exception applies?
Part A covers inpatient care after formal admission to the foreign hospital. Part B covers ambulance and doctor services immediately before and during that covered stay. Medicare does not pay for return ambulance trips home or for doctor visits abroad after the stay ends.
Medicare does not cover dialysis abroad unless it happens during a covered inpatient stay, and Medicare plans cannot cover drugs bought outside the US. Foreign hospitals are not required to file Medicare claims, so you may have to pay and then submit a claim yourself on form CMS-1490S.
Does Medigap cover emergencies in Mexico?
Most Medigap plans do, with limits. Plans C, D, E, F, G, H, I, J, M and N include foreign travel emergency coverage. Plans E, H, I and J are no longer sold, but people who bought them before June 1, 2010 can keep them.
| Medigap foreign travel emergency benefit | Rule as of November 2026 |
|---|---|
| Deductible | $250 per year |
| What the plan pays | 80% of billed charges for certain medically necessary emergency care |
| Lifetime maximum | $50,000 |
| Trip limit | Care must begin during the first 60 days of a trip |
The 60-day condition is the catch for residents. A Medigap plan is built for travel, not for living abroad, so someone who has lived in Mexico City for years should not count on it for routine or ongoing care. Ask your Medigap company how it treats people who live outside the US.
What about Medicare Advantage and Part D?
Medicare Advantage plans follow Medicare’s rules on care abroad, though a plan may add extra benefits for emergency and urgently needed care outside the US. Check the plan’s evidence of coverage, and remember that Advantage plans are tied to a US service area.
Part D drug plans also require you to live in the US. Medicare says that when you move back after living abroad, you can join a drug plan or an Advantage plan during the two full months after the month you return.
Should you keep Part B while living in Mexico?
It depends on whether you plan to return to the US for care. Part B costs a monthly premium, $202.90 for the standard premium in 2026, even though it pays almost nothing in Mexico. Dropping it saves money now but has two costs later:
- A late enrollment penalty. Medicare adds 10% to the Part B premium for each full 12-month period you could have had Part B but did not, and you usually pay it for as long as you have Part B.
- A waiting period. Without a special enrollment period, you can sign up again only in the General Enrollment Period, January 1 to March 31, with coverage starting the month after you sign up.
Medicare’s penalty page does not list living abroad among the situations that avoid the penalty. Before deciding, call 1-800-MEDICARE or the Social Security Administration, and read Medicare’s page on avoiding late enrollment penalties.

How do US retirees in Mexico cover health care?
Many combine several options. Mexican private health insurance, known as major medical expense policies (gastos médicos mayores), covers hospital care in Mexico; see our guide to private health insurance in Mexico for how they work and their age limits. Legal residents can also apply for voluntary coverage with the Mexican Social Security Institute, described in our article on IMSS voluntary enrollment. Some pay cash for routine care and keep Medicare for treatment in the US.
Bottom line
Treat Medicare as US coverage only. Before moving, decide whether you will return to the US for major treatment, price a Mexican policy, and work out what dropping Part B would cost you in penalties if you come back.
FAQ
Will Medicare reimburse me for a hospital stay in Mexico City?
Almost certainly not. The three exceptions involve emergencies on or near the US border or travel through Canada, not living in Mexico City.
Does Medicare cover medical evacuation from Mexico to the US?
Medicare’s foreign coverage rules do not include return ambulance trips home. Evacuation cover comes from separate travel or evacuation insurance.
Can I use my Medicare card at Mexican hospitals?
Foreign hospitals are not required to file Medicare claims, and outside the three exceptions Medicare will not pay. Expect to pay directly or through a Mexican insurer.
