Two questions people mix up
"Does my insurance work abroad?" is really two separate questions, and the answers are often different:
- Emergency care while travelling: you fall ill or are injured unexpectedly. Some plans pay something toward this, usually with conditions, and travel insurance is designed for it.
- Planned treatment abroad: you choose to travel for a procedure. This is much less likely to be covered, because insurers and public systems generally want planned care inside their own networks.
A policy that covers a broken ankle on holiday may pay nothing toward a knee replacement you've booked in another country. Ask about each situation separately.
How major coverage types travel
| Coverage | Emergency care abroad | Planned treatment abroad | Source |
|---|---|---|---|
| US Medicare | Not covered outside the US, per the State Department | Not covered | US State Department, 2025 |
| US private and employer plans | Varies; many don't pay for air ambulance evacuation home | Rarely; check your plan | US State Department, 2025 |
| UK NHS | Government advises comprehensive travel insurance | Possible only via the S2 route (EEA countries and Switzerland) or the EU Directive route, under their rules | NHS, 2021 |
| Colombia's public system | Outside the scope of the law we reviewed | Public funds can't pay for services that must be provided abroad | Ley 1751 de 2015, Art. 15 |
| Travel insurance | Its main purpose; terms vary | Usually excluded; read the policy | Policy wording |
The common thread: national coverage is tied to national providers. Portability is the exception, and where it exists it comes with specific conditions.
United States: Medicare and private plans
The State Department's travel health guidance (updated August 2025) makes three points every US traveller should take seriously:
- The US government does not pay medical bills abroad. Embassies can help you find doctors and hospitals and contact family with your permission, but they won't cover costs.
- Medicare stops at the border: it won't pay for medical care you get outside the US.
- Most plans won't pay to fly you home by air ambulance. The department notes that medical evacuation can cost from $20,000 to $200,000 (USD), depending on where you are and your condition.
It also warns that in many places hospitals require payment or a deposit before treating you. Even if your plan will reimburse you later, you may need to pay first.
If you have Medicare plus a supplemental or Advantage plan, or an employer plan, check its own terms for foreign travel. Don't assume one part of your coverage behaves like another.
United Kingdom: the NHS and Europe
The NHS describes two routes by which UK residents may get NHS-funded planned treatment abroad. The Planned Treatment Scheme (S2 route) may entitle you to NHS-funded treatment in a European Economic Area country or Switzerland. A separate EU Directive route covers some healthcare in Europe. Both have their own eligibility rules and approval steps, which you need to follow before treatment.
Neither route reaches Latin America. A UK resident choosing private treatment in Colombia pays privately. The UK government also advises anyone going overseas to take out comprehensive travel insurance. We cover the European frameworks in more detail in cross-border healthcare policy explained.
Colombia: why public coverage stays home too
Portability problems aren't only for visitors. Article 15 of Ley 1751 de 2015, the statute that governs Colombia's health system, sets out which services public money may not pay for. Alongside services that are mainly cosmetic, experimental or unsupported by evidence, the list includes services that have to be provided abroad. Colombians with public coverage face the same basic rule as Americans with Medicare: coverage is designed for care at home.
Products that are designed to travel
If you need coverage outside your home country, you're usually looking at a product built for that purpose:
- Travel medical insurance covers unexpected illness and injury on a trip. Many policies exclude pre-existing conditions and planned treatment, and some exclude complications of treatment you travelled for.
- Medical evacuation cover pays to move you to an appropriate hospital or home. The State Department suggests considering it as part of travel insurance.
- International or expatriate health insurance is designed for people living abroad, and may cover treatment in several countries. Terms, waiting periods and exclusions vary widely.
- Complications insurance for medical travel is sold by some providers to cover problems arising from a planned procedure. Read exactly what's included and for how long after surgery.
We don't recommend specific insurers. Compare the policy wording, not the brochure.
What to ask your insurer, in writing
Before you travel for treatment, send your insurer these questions and keep the replies:
- Does my plan pay anything for emergency care in [country]? Up to what amount, and do I need to call you first?
- Does it pay anything for planned treatment in [country]? If not, is that stated in my policy?
- If I have a complication after returning home from treatment abroad, will you cover the follow-up care?
- Is medical evacuation or repatriation covered, and under what conditions?
- What documents do you need to process a claim for care abroad: itemised bills, translations, proof of payment, medical reports?
- Will you pay the hospital directly, or must I pay and claim back?
Question 3 is the one people forget. Find out who pays if something goes wrong after you get home. Our guide to aftercare at home after treatment abroad covers how to line up follow-up care before you leave.
Paperwork that keeps your options open
Even when coverage is limited, good records help with any reimbursement claim, tax question or later treatment:
- An itemised invoice showing the provider, the patient, dates and each service.
- Proof of payment, with the currency and exchange rate.
- A discharge summary and operative report, ideally with a translation.
- Details of any implants or devices used.
- Contact details for the treating doctor.
Emergencies are a separate plan
Whatever your policy covers, know where the nearest emergency department is and how it's paid for. Our comparison of emergency care systems explains how emergency access differs between countries.
An illustrative scenario
Illustrative example only, not based on any specific policy. Imagine someone with US employer coverage who books a planned hip operation abroad and buys a standard travel policy for the trip. Three things could happen:
- The operation itself: the employer plan treats it as out-of-network planned care abroad and pays nothing. The travel policy excludes planned treatment. The patient pays the full bill.
- A fall on day two, unrelated to the surgery: the travel policy may well respond, because this is the kind of unexpected event it's designed for.
- A wound infection after returning home: whether the employer plan pays depends on how it treats complications of care received elsewhere. This is exactly the question to ask in advance.
The same trip can involve three different coverage outcomes. Knowing which applies before you go is the whole point of checking.
The Takeaway
Medicare doesn't cover care outside the US, NHS funding for planned care abroad is limited to European routes, and Colombia's public funds don't pay for care that must happen abroad. Treat home coverage as staying home, buy travel or evacuation cover deliberately, and get your insurer's answers in writing before you book.
Frequently asked questions
Does Medicare cover me in Colombia?
No. The State Department's guidance is that Medicare won't pay for care received outside the US. If you have a supplemental or Medicare Advantage plan, check its terms separately, and consider travel medical insurance for your trip.
Will the NHS pay for my operation in Colombia?
No. NHS funding for planned care abroad runs through the S2 and EU Directive routes, and both are limited to Europe. A UK resident treated in Colombia pays the bill themselves.
Does travel insurance cover surgery abroad?
Standard travel insurance is designed for unexpected illness and injury, and usually excludes planned treatment. Some policies also exclude complications of treatment you travelled for. Read the exclusions before buying.
How much does a medical evacuation cost?
The State Department says air ambulance evacuation can cost from $20,000 to $200,000, depending on location and condition, and that most health plans don't pay for it. Evacuation cover is sold as part of many travel insurance policies.
Will my insurer cover complications after I get home?
It depends on your policy. Ask your insurer in writing before you travel, and arrange follow-up care at home in advance so you aren't trying to find a doctor while recovering.
