Original Medicare generally does not cover care in Mexico. Narrow foreign-hospital exceptions and some supplemental emergency benefits exist, but they do not provide routine resident healthcare.
In this guide
Original Medicare's foreign-hospital exceptions
Medicare lists three specific circumstances for foreign-hospital coverage: an emergency begins in the US and an appropriate foreign hospital is closer; an emergency occurs during qualifying direct travel through Canada between Alaska and another state; or a person lives in the US and the appropriate foreign hospital is closer to home.
Being a US citizen, having a Medicare card or developing an emergency while living in Mexico does not by itself satisfy these exceptions. Ask Medicare about an actual claim rather than assuming a border hospital is automatically covered. See Medicare's overseas fact sheet.
Medigap foreign travel emergency benefits
Certain Medigap plans include a limited foreign-travel emergency benefit. Medicare describes coverage for qualifying emergency care beginning within the first 60 days of a trip, paying 80% after a USD 250 annual deductible, subject to a USD 50,000 lifetime limit.
Verify that your exact policy has the benefit and how it defines a trip. These limits make it different from a policy intended for ongoing residence in Mexico. It is not a general benefit for planned surgery, routine appointments or indefinite stays.
Medicare Advantage and Part D
Some Medicare Advantage plans offer additional overseas benefits. Request the current Evidence of Coverage and ask about emergency definitions, payment limits, reimbursement and residence or service-area rules. Advertising that says “worldwide emergency” does not establish routine Mexican coverage.
Medicare drug plans do not cover prescription drugs purchased outside the US. Plan your local medication supply separately.

Before changing Medicare enrollment
Keeping Medicare may preserve access to eligible US treatment when you return. Dropping or delaying coverage can affect enrollment timing and penalties. Do not assume that a Mexican policy or voluntary IMSS enrollment provides an exemption from Part B rules.
Review your specific eligibility and enrollment situation with Medicare or Social Security before cancelling. Medicare's penalty guidance is a starting point, not a personal determination. Also ask how a move affects your Medicare Advantage or prescription plan.
Build a Mexico care plan
Compare eligibility for voluntary IMSS with the underwriting terms of a private or international plan. Existing conditions and initial age eligibility may limit options. Obtain acceptance and a start date before treating a new policy as active protection.
For self-pay care, request local provider quotes and plan hospital deposits and a claims reserve. Returning to the US for treatment is a separate logistical decision: urgent care may need to begin locally, and transport is not automatically covered. Review medical evacuation terms.
Keep your Medicare and supplemental policy details, Mexican assistance contacts and medical summary available to whoever would help in an emergency.
Frequently asked questions
Will Medicare pay for a Mexican emergency room visit?
Usually no. Original Medicare's foreign-care exceptions are narrow, and an emergency occurring in Mexico does not automatically qualify.
Is Medigap enough for living in Mexico full-time?
Its foreign emergency benefit has trip, deductible and lifetime limits. Confirm your policy; it is not routine resident health insurance.
Should I cancel Part B when moving?
Resolve your personal enrollment, penalty and return-to-US circumstances with Medicare or Social Security before deciding. Local coverage does not automatically remove those consequences.
