How To Handle Medical Bills and Insurance Abroad: What Every Traveler Needs To Know

 Most travel insurance claims are not denied because something wasn’t covered. They are denied because of one missing piece of information on one receipt, a code most travelers have never heard of, and most hospitals won’t include unless you specifically ask.

That single code could mean the difference between full reimbursement, a months-long delay, or a denial that costs you thousands of dollars out of pocket.

Knowing how these codes work is essential for every traveler, even if they never need them.

Does My Health Insurance Cover Me Abroad?

Most travelers assume that travel insurance, whether bundled with a credit card or purchased as an add-on, is essentially the same as a full, standalone policy. Unfortunately, this is incorrect, and it is one of the most costly assumptions a traveler can make.

Not all travel insurance is equal. It is critical to purchase a full travel insurance policy that covers your specific needs, activities, and destination. A limited or bundled policy will not serve you in a real emergency. Know what you are buying before you need it.

Here is what most travelers also get wrong: travel insurance is not your primary   Your home country’s primary health insurance always pays first for medical illness, injury, and hospitalization abroad. Travel insurance is secondary. It covers what your primary insurance does not, including deductibles, coverage gaps, and items your primary plan excludes overseas. Both work together, but your primary insurance always leads.

Before you leave home, call your primary health insurance and ask these questions:

∙ I will be traveling to (name the country). What is my coverage?

∙ Can you provide me with a dated letter of proof of coverage on letterhead stating my coverage amounts, limits, and what is covered overseas? This letter is typically valid for 1 year; request it annually, and you are covered for every trip.

∙ Will my deductible be waived for emergency medical care abroad? Many insurance companies will waive deductibles for emergency care, but you need to ask before you go.

∙ If you are covered by Medicare or a government health care plan, contact them directly. There may be very limited or no coverage overseas. Ask specifically which countries they have agreements with and what your individual coverage includes.

Make sure you have your physical insurance card with you on every trip. You will need it for follow-up visits and ongoing care.

One thing every traveler needs to be prepared for, regardless of coverage, is that most overseas medical facilities require payment up front. You pay first, submit your documentation, and then wait for reimbursement. Being financially prepared before you travel is not optional; it is essential.

What I learned the hard way:

I thought I had done everything right. I had my letter from my primary insurance company, a comprehensive travel insurance policy that fit my needs, and all my documents in order. What I was not prepared for came after, and it cost me money.

After receiving medical care abroad, I gathered all my receipts and submitted my claim, expecting reimbursement. My primary insurance denied it. The reason is that a diagnosis code was missing on the receipt, and the doctor had documented the services performed, but not the actual diagnosis. Without that code, my primary insurance had no basis to process the claim.

Getting that information after the fact from an overseas provider is extremely difficult. Phone calls go unanswered. Emails are ignored. And the clock is ticking. Without the correct documentation from the primary insurance, travel insurance often will not pick up the claim either, because they require the same paperwork. When one falls, the other follows.

What started as a missing code cascaded into a denied primary claim, a rejected travel insurance claim, and the potential for the entire bill, including trip delay coverage and transportation costs, to be charged to me. All because of one missing piece of information I could have obtained before I left the clinic.

I will explain exactly what that code is and how to get it in Section 4. It is the most important thing in this article.

Why Travel Insurance Claims Get Denied

Beyond missing documentation, another costly mistake most travelers never see coming is an incomplete itinerary.

Whether you are traveling for a two-week holiday or an extended period, 30 or 60 days, your travel insurance policy requires a complete and continuous itinerary. 

Every destination, hotel, flight, and mode of transportation must be documented and linked. A gap in that itinerary can cost you everything.

I learned this firsthand. I fell ill in a country and had to miss my flight and extend my hotel stay by two weeks due to medical care. I had comprehensive primary health coverage and extensive travel insurance. I was confident I was covered. I was wrong.

One short commuter flight to my next destination had not been included in my itinerary, a single gap in an otherwise complete travel plan. Because my itinerary was not continuous, my hotel extension, missed flight, daily food allowance, and additional expenses were all denied. 

The frustration of dealing with that on top of being ill was significant. Know your policy. If you have questions, ask before you travel, not after.

What most travelers do wrong when filing a claim:

Many insurance companies now offer apps to file claims while traveling, a helpful tool in theory. In practice, if your situation does not fit neatly into a specific prompt or category, these apps become useless. Do not rely on them alone.

The number one mistake travelers make when filing a claim is failing to submit all their documents. Submit everything: receipts, medical records, images, prescriptions, and even photos you have taken. Every piece of documentation strengthens your claim.

Keep a running log on your phone or in a document of every date and time for treatment and follow-up visits. Record every contact you make with your insurance company, how you contacted them, the date, time, and name of the person you spoke with. Always note your claim or case number so you can reference it quickly without having to start from scratch every time you call.

Timing matters more than most travelers realize:

Contact both your primary and travel insurance companies as soon as possible, before or immediately after treatment. Contact with both insurers is not just about filing a claim. It is about accessing the resources and support that both companies can provide you during a vulnerable situation.

Check with both insurance companies how long you have to file your claim after treatment is complete. Some insurers ask you to file once treatment is fully complete rather than during ongoing care. In many cases, you have up to a calendar year to file for reimbursement, but travel insurance timelines vary, so check your policy when you purchase it.

The resources that both companies can give you allow you to focus on getting better rather than stressing about paperwork in the middle of treatment. If you find yourself in financial hardship during your recovery, contact your travel insurance company; they may be able to assist with some expenses before your claim is fully processed.

Both companies will work together, and in most cases, you will be assigned a dedicated agent who knows your case and can be an invaluable resource throughout the process.

What most travelers don’t know about exclusions:

No travel insurance policy covers everything, not even the best ones. Activities, destinations, and missing documentation can all trigger limitations or exclusions. What you hear from friends or see on social media about travel insurance covering everything is not the full picture. Travelers, it is why choosing the right policy for your specific needs, activities, and destination before you travel is so important. Read your policy. Know your exclusions. Ask questions before you go.

 

What Documents Do You Need To File A Medical Claim Abroad?

The section most travelers skip and the one that costs them the most. Read it before you need it.

Every insurance company is different, but here are the most common and standard documents you will need to file a medical claim abroad. Having these ready before you leave any clinic or hospital will save you significant time, money, and frustration.

The essential documents:

∙ A line-by-line itemized statement of all services and procedures performed. Not just a receipt, it is a complete breakdown of every charge.

∙ A doctor’s statement of your diagnosis, the treatment performed, and any follow-up instructions. Understanding, this is a separate document from your itemized statement, not just your billing summary.

∙ Physical receipts for every credit card or cash payment. Pay separately for any items that fall outside your primary treatment. For example, if your doctor recommends a cream or medication, pay for it separately and get a separate receipt. Prescriptions and OTC medications often follow different reimbursement processes. If they appear on the same receipt as your treatment, it will delay your payout and create confusion during processing.

∙ The ICD diagnosis code on all documents. I will cover this in full detail in What Is an ICD Code and Why Does It Matter? It is the most critical piece of your entire claim.

∙ Any tests, X-rays, or imaging keep physical copies and request them on CD before you leave the facility. Keep these on hand in case you are asked for additional proof.

∙ The official claim form required by your insurance company. These are found on their website. Make sure every form is signed and dated before you submit. Missing a signature or date will delay your payment.

Digital and physical copies keep both:

Keep both digital and physical copies of every document until your claim is fully paid. A scanning app and cloud storage make this simple and secure. Once your claim is fully paid and closed, you can shred the physical copies. Always hold on to physical copies of tests and X-rays on CD. These are worth keeping long-term.

How to submit:

Most primary health insurance and travel insurance companies have secure online portals where you can upload your documents directly. By far, it is the fastest and most secure way to file. If additional information is needed, a representative will often send you a secure email link to speed up the process. 

Always use a VPN when submitting any personal health information while traveling abroad. Your privacy and security matter, especially when you are vulnerable and away from home.

Document your treatment with photos and video:

Take photos or short videos throughout your treatment, from the initial injury or illness through recovery. Every image is automatically time-stamped, creating a verifiable record of your treatment timeline. If your insurance company is missing a code or needs additional proof, these photos can be reviewed by their medical professionals to help process your claim. Visual documentation of your injury, swelling, or visible symptoms has helped travelers get claims processed that might otherwise have been delayed or denied.

Processing times and follow-up:

In most cases, claim processing takes anywhere from 30 to 90 days, depending on the insurance company and whether all documents were submitted correctly. Do not assume no news is good news. After a couple of weeks, follow up with the company to confirm they received all your documents and that nothing additional is needed to process your claim.

I have been in the situation of waiting 30 days only to find out the insurance company never received one of my documents, or something was not signed correctly. That delay was entirely avoidable. The insurance companies will not contact you if something is missing or incorrect; you have to advocate for yourself. Stay on top of it. A quick follow-up call or message every few weeks keeps your claim moving and prevents unnecessary delays.

What Is An ICD Code And Why Does It Matter?

Over years of navigating medical claims abroad, I learned that ICD codes are the single most important piece of documentation that most travelers never know to request.

An ICD code, which stands for International Classification of Diseases, is a standardized global system of codes used by the medical and insurance industries to identify and describe specific injuries, illnesses, or treatments. Every diagnosis has a code. Every procedure has a code. These codes are what insurance companies use to process and pay your claim. Without them, your claim has no medical basis and will be denied or delayed regardless of how much documentation you have submitted.

The system is detailed and organized by subcategories far more specific than most people realize. For example, a broken leg is not simply a broken leg. The ICD-10 codes for lower leg fractures alone include:

∙ S82.90XA — Unspecified fracture of unspecified lower leg, initial encounter

∙ S82.91XA — Unspecified fracture of right lower leg, initial encounter

∙ S82.92XA — Unspecified fracture of left lower leg, initial encounter

Some countries use ICD-10, while others have updated to ICD-11, a more current version of the same system. The codes are updated annually. For most insurance claims, as long as the correct ICD code appears on each line item of your documentation, your claim will process smoothly.

What to do if the provider says they don’t have these codes:

It has happened more often than you would expect, particularly in countries with universal healthcare systems, where providers find Western insurance documentation requirements cumbersome and frustrating. 

Sometimes it is a language barrier. Sometimes, it is a lack of familiarity with the complexity of submitting claims to Western insurance companies. Stay friendly, patient, and as helpful as possible. Most of the time, they will accommodate you.

What I have done in these situations is Google the specific ICD code for my condition and show the provider directly on my phone. Once they see what I am referring to, they will either confirm the code themselves or send it to their billing department for correction.

What to do if your claim is denied because of a missing or incorrect ICD code:

1. Contact your primary or travel insurance and ask specifically what part of the claim is being denied and why. Many times, it is a single coding error, one wrong code, that is the difference between a claim being paid or denied.

2. Contact the overseas provider directly. Email is often too slow, and responses are inconsistent. Call the provider and ask to speak with the billing department. Keep the conversation specific and factual. You may need to speak with more than one person before the issue is resolved.

3. Stay on the phone while they email you the corrected documents. Confirm you have received them before you hang up. I found this to be the most efficient way to resolve the issue with the correct coding.

4. Re-submit your claim with the corrected documents and follow up with your insurance company within a week or two to confirm receipt and check if anything else is needed.

5. Be aware that resubmitting a corrected claim will typically restart the processing time clock. Be patient, but stay on top of it.

The bottom line on ICD codes:

At times, ICD codes can seem like a daunting detail when you are already injured or ill, especially when your medical professional has provided a written statement. 

The reality is that this is standard practice for the global medical processing industry. Know that you have access to all of these codes. When a claim is denied, you can look it up, identify the issue, and advocate to get it corrected. That knowledge alone could save you thousands.

 

What Is A Fit To Fly Certificate?

Have you heard of a Fit to Fly certificate? I hadn’t until I needed one.

As I shared in my previous article, I suffered a serious injury abroad that required emergency surgery and hospitalization. What I didn’t anticipate was that I wouldn’t be cleared to fly home for 6-8 weeks. Fit to Fly is exactly what it sounds like: a medical clearance issued by your treating physician stating that you are safe to travel without risk of serious complications.

Your medical team makes this determination based on your condition, your recovery, and the demands of travel. They will also specify what assistance or accommodations you may need to travel safely. Airlines require this documentation to make the appropriate arrangements, including seating, boarding assistance, and other accommodations. There are many different types of Fit to Fly orders depending on your situation and your condition.

Your primary health insurance and travel insurance will also require a Fit to Fly certificate before they arrange transport back to your home country. It is both a liability waiver and a set of guidelines outlining exactly how you need to travel.

In my situation, I was unable to sit upright for an extended period on a long-haul flight. My doctor specified that I needed to travel lying flat and required a medical escort from the hospital to my home country, door to door, every step of the way. It is why having the right travel insurance made all the difference. Without it, I would have been entirely responsible for the cost of those arrangements. With it, I only had to focus on my recovery.

Choosing the right travel insurance before you leave is not just about covering medical bills. It is about making sure you can get home safely when you need to.

 

How Do I Get Reimbursed For Medical Expenses Abroad?

Once your claim is approved, getting your money back is more straightforward than most travelers expect if you know what to look for.

How payment is delivered:

Most larger health insurance and travel insurance companies offer electronic payment options. Review your claim form carefully. There is often a section where you can opt for electronic payment and enter your banking information directly. I have used this option for years, and it works smoothly and reliably.

Some companies use secure payment apps. When your claim is approved, they send you a secure link, and you choose at that time how to receive your funds. Travel insurance companies, in particular, are accustomed to clients being on the go and tend to have flexible digital payment options.

Smaller companies and certain divisions within larger insurance companies may still issue checks. For example, a prescription reimbursement and a medical claim may appear to be part of the same incident, but are often handled by entirely separate divisions with different protocols and payment methods.

Checks are typically sent to the default address on file with your primary insurer, which is usually your home address. Having a trusted family member or friend who can access your mail becomes invaluable. They can forward the check to you or deposit it on your behalf using your banking app. It is worth checking with your individual insurance companies before your trip to understand exactly how they process payments.

If your payment is less than expected:

Your insurance company will send you an EOB (Explanation of Benefits). This document shows exactly who paid, how much was paid, and the breakdown of every line item service. Review it carefully. If something does not look correct, the easiest first step is to call your insurance company directly. 

In many cases, they may be waiting for additional documentation before releasing the full payment. Once submitted, the claim will be reviewed and paid; it just takes additional time.

One important detail to keep in mind: if you paid for medical care in a foreign currency, your insurance company will convert the reimbursement at the current exchange rate. Depending on market fluctuations, this can slightly affect the amount you receive. 

If your claim is still denied after resubmission:

If you have submitted all your documents, verified the coding, and your claim is still being denied, you have the right to appeal. Most companies allow one or two appeals, depending on their policy. Be aware that appeals take time and can drag on. 

Ask yourself an honest question: Is this worth my time and energy? 

Medical treatment in many countries is significantly less expensive than in your home country. For non-catastrophic claims or smaller amounts, the time and stress of an extended appeals process may not be worth it.

You Came Here Because of One Code. You are leaving with the knowledge you hope you never need.

When I started this article, I told you that most travel insurance claims aren’t denied because something wasn’t covered. They are denied because of one missing piece of information on one receipt.

Now you know what that code is. You know how to get it, how to use it, and what to do if it is missing. You know how to file a claim, follow up on it, appeal it, and receive payment. You know what an EOB is, what a Fit to Fly certificate means, and why a complete itinerary is just as important as your documentation.

Most travelers only learn these things the hard way: after a denial, a delay, or a bill they were not expecting. You now know them before you ever need them.

Here is a thought I want you to remember: medical care abroad is not always a compromise.

During my own recovery from emergency surgery abroad, I received an advanced treatment that in my home country was reserved exclusively for professional athletes. I would never have had access to it at home. The experience was hard and scary. The care was exceptional.

Being prepared does not just protect you financially. It frees you to focus on what matters most: your recovery, your safety, and eventually getting back to doing what you love.

The world is still waiting for you. Go prepared.
