Many Americans who move to Mexico assume their Medicare coverage will follow them abroad. Unfortunately, Medicare does not pay for healthcare services received outside the United States.
If you live in Mexico full time or spend significant time here, it’s important to understand how Medicare works internationally and what options are available to protect yourself.
As a U.S.-licensed insurance broker specializing in Americans living in Mexico, this is one of the most common questions I receive.
This guide explains how Medicare works abroad and what healthcare options expats typically consider.
Does Medicare Work in Mexico?
Medicare does not cover healthcare services received in Mexico.
Medicare was designed primarily for healthcare providers inside the United States, and hospitals outside the country cannot bill Medicare directly.
This means if you receive treatment at a hospital or clinic in Mexico, Medicare will not reimburse those medical expenses.
For Americans living abroad, this can create a coverage gap if medical treatment is needed while outside the United States.
Why Medicare Usually Does Not Cover Healthcare Abroad
Medicare was created to support healthcare services provided within the United States. Because of this, the program generally only pays for treatment performed by healthcare providers operating within the U.S. medical system.
Hospitals and doctors in Mexico do not participate in the Medicare program, which means they cannot submit claims directly to Medicare for payment.
As a result, Medicare coverage is limited to treatment that occurs inside the United States or its territories.
Rare Situations Where Medicare May Cover Care Outside the United States
There are a few limited situations where Medicare may pay for medical care received outside the United States, although these cases are uncommon.
Emergency Near the U.S. Border
If you experience a medical emergency and the closest hospital capable of treating you is in another country, Medicare may cover the treatment.
Travel Between Alaska and Another U.S. State
If you are traveling between Alaska and another U.S. state through Canada and a medical emergency occurs, Medicare may cover the care.
A Foreign Hospital Is Closer Than a U.S. Hospital
In rare cases where a foreign hospital is closer than a U.S. hospital capable of treating the emergency, Medicare may provide coverage.
These situations are very specific and does not apply to Americans who are living in Mexico full time.
What Most American Expats in Mexico Actually Do
Because Medicare generally does not cover healthcare outside the United States, Americans living in Mexico usually choose one of several strategies for healthcare coverage.
Option 1: Keep Medicare and Pay Out of Pocket in Mexico
Some expats keep their Medicare coverage in case they return to the United States but pay out of pocket for healthcare services in Mexico.
Private healthcare in Mexico is often significantly more affordable than in the U.S., which makes this approach workable for routine medical care.
Option 2: Keep Medicare A/B, and Purchase International Health Insurance
Many expats keep Medicare A/B while also purchasing an international health insurance policy that covers them in Mexico and worldwide.
This provides protection against major medical events and allows access to private hospitals in Mexico.
Option 3: Cancel Medicare Part B and Use Private Insurance
Some Americans who plan to live abroad long term choose to cancel Medicare Part B and rely on private international health insurance instead.
This decision depends on personal circumstances and long-term plans for returning to the United States, since Part B has a 10% penalty per year that you are not enrolled if you ever do enroll back into it in the future.
Healthcare Costs in Mexico
One reason many Americans feel comfortable living in Mexico without relying on Medicare is the affordability of private healthcare.
| Treatment | Typical Cost |
|---|---|
| Doctor consultation | $40 – $100 |
| MRI | $300 – $600 |
| Emergency room visit | $150 – $500 |
| Surgery | Often 60–80% less than the United States |
While healthcare in Mexico is generally much more affordable than in the U.S., major medical procedures or hospitalizations can still cost tens of thousands of dollars.
Because of this, many expats choose to carry private health insurance for protection against larger medical events.
Can You Keep a Medicare Advantage Plan if You Live Outside the United States?
Medicare Advantage plans are regional health insurance plans that operate within specific service areas in the United States. In order to enroll in and maintain a Medicare Advantage plan, you must live within the plan’s service area. The US address listed on your Advantage application.
If you move outside the United States permanently and no longer maintain a residence in the plan’s service area, you are no longer eligible to remain enrolled in that Medicare Advantage plan.
Because of this requirement, Medicare Advantage plans are not suitable for Americans who live abroad full time.
Even if someone initially enrolls in a Medicare Advantage plan before moving overseas, they may be disenrolled and cancelled once the plan determines they no longer reside in the service area.
For Americans living abroad, Original Medicare combined with other private health insurance strategies is usually a more practical approach.
How Medicare Supplement (Medigap) Plans Work Outside the United States
Medicare Supplement plans, also known as Medigap policies, are designed to work alongside Original Medicare (Part A and Part B). These policies help pay deductibles, copays, and coinsurance that Medicare does not cover.
Many Americans who move to Mexico choose to keep their Medigap policy because it provides strong coverage if they return to the United States for medical treatment.
Foreign Travel Emergency Benefit
Several Medigap plans include a limited benefit for emergency medical care outside the United States. This benefit is intended for short trips abroad rather than long-term residence in another country.
Typically, the foreign travel emergency benefit includes:
- Coverage for emergency medical care outside the United States for the first 60 days of the trip only!
- A lifetime maximum benefit of $50,000
- A deductible (usually $250)
- The policy paying 80% of covered emergency costs
This coverage usually applies only during the first 60 days of a trip outside the United States.
What This Means for Americans Living in Mexico
Because of these limitations, Medigap policies generally do not provide meaningful coverage for healthcare in Mexico if you are living abroad full time.
However, many expats still keep their Medigap policy because it provides excellent protection if they return to the United States for medical care.
For Americans living abroad, Medigap is often used as a way to maintain strong healthcare coverage in the U.S. while arranging separate healthcare coverage in Mexico.
The Bottom Line
If you live in Mexico, it is important to understand that Medicare alone will not provide meaningful coverage for healthcare outside the United States.
Many Americans living abroad combine Medicare with other strategies such as private international health insurance.
The best approach depends on your personal circumstances, travel habits, and long-term plans.
