When You Actually Need International Health Insurance

Who needs international health insurance and why

International health insurance is for people who spend significant time outside their home country and need medical coverage that works across borders. Your domestic health plan — whether it's through an employer, Medicare, or a private policy — typically does not cover you once you leave the United States, or covers you only minimally. If you get sick or injured abroad, you could face bills in the tens of thousands of dollars with no way to submit them to your home insurer.

You need international coverage if you are moving to another country for work, studying abroad for more than a few months, retiring overseas, or traveling for extended periods. You also need it if you are a foreign national living in the US on a visa and your visa status does not include health coverage. The difference between travel medical insurance (which covers short trips) and international health insurance is duration and scope: international plans are built for people who will be outside the US for months or years, and they cover routine care, not just emergencies.

People who do not need international health insurance include those taking a two-week vacation (travel medical insurance covers that), US citizens with Medicare who are staying in the US, and employees whose company provides coverage that extends to their destination country. If you are unsure whether your current plan covers you abroad, call the customer service number on your insurance card before you leave — most plans have a specific international line.

Key Takeaways

• International health insurance is necessary if you will be living or working outside the US for more than a few months, because your US health plan almost certainly will not cover you there.
• Plans vary widely in what they cover: some include routine doctor visits and prescriptions, others cover only emergencies, and some require you to pay upfront and claim reimbursement later.
• The cost depends on your age, the countries you will be in, and what type of coverage you choose — plans for young people in Western Europe cost less than plans for older people in countries with expensive healthcare systems.
• You can buy international insurance before you leave the US, or in some cases after you arrive in your destination country, but waiting can mean gaps in coverage or higher premiums.
• Some countries require proof of health insurance before they will issue a visa or residency permit, so check your destination's requirements before you book your move.

Types of international health insurance and what they cover

Expat health insurance is the most common type for people relocating long-term. These plans cover routine doctor visits, hospital stays, emergency care, and prescriptions in your destination country and often in multiple countries. They typically have a deductible (the amount you pay before insurance kicks in) and a maximum annual payout. Some plans let you see any doctor; others require you to use a network of approved providers. Premiums run from roughly $100 to $500 per month depending on your age and location, though this varies significantly.

International student plans are designed for people studying abroad and usually cost less than expat plans because they assume you are younger and will be in one country for a defined period. They cover emergency care and often routine visits, but may have lower maximum payouts than expat plans. Schools sometimes require students to purchase a specific plan or proof of equivalent coverage.

Travel medical insurance (covered in the previous section) is short-term coverage for trips lasting days to weeks. It is not the same as international health insurance and does not work for people relocating.

Visa-specific insurance is required by some countries as a condition of entry. The Schengen countries in Europe, for example, require visitors to carry insurance with a minimum coverage amount. Some countries like Thailand and Mexico do not legally require it but many employers or visa sponsors do. Check your destination country's visa requirements before you purchase a plan.

How to figure out what coverage you actually need

Start by identifying what your destination country's healthcare system looks like and what it costs. A doctor visit in Portugal might cost $30 to $50 out of pocket; the same visit in Switzerland could cost $150 to $300. Hospital stays vary even more widely. Research the average cost of common procedures in your destination — a broken arm, a dental filling, a night in a hospital — so you know what you are protecting yourself against.

Next, determine whether your destination country requires health insurance as a condition of residency or visa approval. Many countries do, and some specify a minimum coverage amount or require the policy to be purchased from an approved provider. Your destination's immigration website or your visa sponsor should tell you this. If insurance is required, you have less flexibility in what you can choose.

Consider whether you will need coverage in multiple countries or just one. A plan that covers only your destination country is usually cheaper than a plan that covers you globally or in multiple regions. If you plan to travel within your region (for example, traveling around Europe while based in one country), confirm that your plan covers those trips or whether you need a separate travel policy.

Think about what types of care matter to you. If you have a chronic condition like diabetes or high blood pressure, you need a plan that covers ongoing medication and doctor visits, not just emergencies. If you are young and healthy, you might choose a plan with a higher deductible to lower your monthly cost. If you are over 60 or have pre-existing conditions, your options narrow and premiums rise — some insurers will not cover people over a certain age, or will exclude pre-existing conditions entirely.

Where to buy international health insurance

You can purchase international health insurance directly from insurers, through brokers who specialize in expat coverage, or sometimes through your employer if you are relocating for work. Buying directly from an insurer means you handle all communication yourself; using a broker means someone helps you compare plans and handles paperwork, usually at no cost to you because the broker is paid by the insurer.

Major insurers that offer international plans include Allianz, Cigna, IMG Global, and Aetna International, though availability varies by country and age. Smaller regional insurers often offer plans specific to certain countries or regions. Your destination country may also have local insurers that offer plans to foreign residents — these are sometimes cheaper and always cover local providers well, but may not cover you if you travel outside that country.

Timing matters: some insurers will not sell you a policy if you have already left your home country or if you are already in your destination country. Others allow you to purchase after arrival but may charge a higher premium or impose a waiting period before coverage begins. If your destination country requires insurance as a visa condition, you usually need to purchase before you apply for the visa, which means buying before you leave home.

Compare at least three plans before you buy. Look at the deductible, the maximum annual payout, what is and is not covered, whether you can see any doctor or must use a network, and what the process is for claiming reimbursement. Read the fine print about pre-existing conditions, pregnancy, and dental or vision care — these are common exclusions.

Cost factors and what affects your premium

Your age is the single biggest factor in what you pay. A 25-year-old might pay $100 to $150 per month for basic expat coverage in a Western European country; a 55-year-old in the same country might pay $400 to $600 per month for the same coverage. Premiums jump significantly at age 60 and again at 65.

Your destination country affects cost because healthcare systems and provider costs vary widely. Insurance for someone in Portugal or Mexico is cheaper than insurance for someone in Switzerland or Australia. If you are moving to a country with a very expensive healthcare system, you will pay more.

Your coverage level matters: a plan with a $500 annual deductible and a $2 million maximum payout costs more than a plan with a $2,000 deductible and a $500,000 maximum. A plan that covers routine visits and prescriptions costs more than one that covers only emergencies and hospital stays.

Pre-existing conditions can increase your premium or disqualify you entirely from some plans. Some insurers will cover pre-existing conditions if you purchase within a certain window (for example, within 14 days of leaving your home country), but will exclude them if you wait longer. If you have a serious pre-existing condition, you may have very few options and will pay significantly more.

What international insurance typically does not cover

International health insurance almost never covers routine dental work, vision care, or hearing aids — these are usually excluded or available only as expensive add-ons. Cosmetic procedures are not covered. Mental health and psychiatric care are often excluded or limited to a small number of visits per year.

Many plans exclude or limit coverage for pregnancy and childbirth, especially if you become pregnant after the policy starts. Some plans will not cover you if you are traveling to a country specifically for medical treatment (called "medical tourism"). High-risk activities like professional sports or mountaineering are often excluded.

Pre-existing conditions may be excluded entirely, or covered only if you purchase within a specific timeframe after leaving your home country. Alcohol or drug-related injuries are sometimes excluded. Check your specific policy's exclusions list before you buy — these vary widely between insurers.

How to use your international insurance when you need care

When you need medical care, your first step is to call your insurer's claims line or use their app to find an in-network provider if your plan has one. In-network providers bill your insurance directly, so you pay only your deductible or copay. Out-of-network providers require you to pay upfront and submit a claim for reimbursement later, which can take weeks or months.

For emergencies, go to the nearest hospital or call emergency services — your insurer will sort out the billing afterward. Keep all receipts, medical records, and documentation of what was done and why. Your insurer will need these to process your claim.

Some plans require you to get approval before certain procedures or hospital stays. Check your policy documents to see what needs pre-approval and what does not. Failing to get approval when required can result in a denied claim or reduced reimbursement.

If you are claiming reimbursement, submit your claim within the timeframe your policy specifies — usually 30 to 90 days. Include receipts, an itemized bill from the provider, proof of payment, and any medical records. If your claim is denied, ask the insurer in writing why and request an appeal if you believe the denial is wrong.

Frequently Asked Questions

Can I use my US health insurance while living abroad?

Most US health plans do not cover you outside the United States, or cover you only for emergency care in very limited circumstances. Medicare does not cover you abroad at all. Call your insurer before you leave to confirm what, if anything, is covered internationally. If coverage is minimal or nonexistent, you need international health insurance.

What happens if I do not have health insurance in my destination country?

If you get sick or injured without insurance, you will have to pay out of pocket for all medical care. Bills can reach tens of thousands of dollars for hospital stays or surgery. Some countries require proof of insurance as a condition of residency, so you may not be able to legally stay without it. Even if not legally required, going uninsured is a serious financial risk.

Can I buy international health insurance after I arrive in my destination country?

Some insurers allow you to purchase after arrival, but many do not. Those that do often charge higher premiums or impose waiting periods before coverage begins. If your destination country requires insurance as a visa condition, you must purchase before you apply for the visa. It is safest to buy before you leave home.

Does international health insurance cover me if I travel to other countries while living abroad?

This depends on your specific plan. Some plans cover you throughout a region (for example, all of Europe) or worldwide. Others cover only your destination country and require a separate travel policy if you leave. Check your policy documents or ask your insurer before you travel.

What should I do if my claim is denied?

Ask the insurer in writing why the claim was denied and request a detailed explanation. Review your policy to confirm the service should be covered. If you believe the denial is wrong, submit a written appeal with any additional documentation that supports your case. Keep copies of everything you send.
