For most patients the best combination is a credit card with no foreign transaction fee for anything you might need to dispute, and a low-cost transfer service for large balances the clinic wants by bank transfer. Whatever you use, always pay in the local currency when a card terminal offers you dollars.
Patients spend weeks comparing surgeons and quotes, then lose a surprising amount of money at the last step: paying. Bank wire fees, poor exchange rates, and card terminal tricks can add up on a five-figure bill. The method you choose also affects what you can do if the clinic doesn't deliver what you paid for.
The options at a glance
| Method | Typical cost drivers | Dispute options | Best for |
|---|---|---|---|
| Credit card (no foreign transaction fee) | Card network exchange rate; any clinic card surcharge | Strongest: card disputes and chargebacks | Deposits, smaller balances, anything you might contest |
| Credit card (with foreign transaction fee) | Foreign transaction fee (often around 3%) plus exchange rate | Same as above | Only if no better card is available |
| Bank wire (SWIFT) | Outgoing wire fee, possible intermediary bank fees, bank's exchange markup | Weak: wires are hard to reverse | Large balances when the clinic requires it |
| Transfer service (e.g., Wise) | Disclosed transfer fee; rate close to the mid-market rate | Weak: like a wire, hard to reverse once delivered | Large balances by bank transfer, at lower cost than most bank wires |
| Cash | ATM fees, bad exchange rates, theft risk | None | Small local expenses only |
The one rule that saves the most money: pay in local currency
When you pay by card abroad, the terminal may ask whether you'd like to pay in US dollars or the local currency (Colombian pesos, Mexican pesos, Turkish lira, and so on). Choosing dollars triggers dynamic currency conversion, where the merchant's processor sets the exchange rate. That rate is usually worse than your card network's rate, and your card may still charge its foreign transaction fee on top.
Always choose the local currency. If a clinic processes your card in dollars without asking, ask them to rerun it in local currency before you sign. On a large surgical bill, that one choice can matter more than any other fee on this page.
Paying by credit card
Cards are usually the most protective option, because card issuers generally let you dispute charges for services you didn't receive as agreed. Bank transfers and cash don't offer that.
- Use a card with no foreign transaction fee. Many travel and premium cards waive it.
- Call your card issuer before you travel. A large foreign charge can trigger a fraud block at the worst moment. Ask about your credit limit, too.
- Ask the clinic about card surcharges before you arrive. Some clinics add a percentage for card payments, which may still be worth it for the protection.
- Keep the itemized invoice and the card receipt together. You'll need both for any dispute, and for HSA or tax purposes.
Paying by bank wire
Many clinics ask for the balance by bank transfer. A traditional bank wire works, but it's often the most expensive and least transparent option:
- Your bank charges an outgoing international wire fee.
- Intermediary banks along the way may deduct fees, so the clinic can receive less than you sent.
- Your bank's exchange rate usually includes a markup over the market rate, which often costs more than the visible fee.
- Once a wire is sent, it's very hard to recall.
Only send money to an account in the clinic's legal business name, and confirm the bank details by phone using a number from the clinic's official website. Never trust changed bank details sent by email or WhatsApp. Account-change scams target exactly this kind of large, one-time payment.
Using a transfer service like Wise
Transfer services were built for this problem. Wise, for example, shows its fee up front and converts at a rate it describes as the mid-market rate, which for large amounts is often noticeably cheaper than a traditional bank wire. Before you use any service, compare the total amount the clinic will receive against your bank's quote on the same day.
- Get the clinic's full bank details in writing, in the clinic's business name.
- Confirm them by phone using the number on the clinic's official site.
- Get a quote from your bank and from the transfer service for the same amount.
- Send a small test payment first if the clinic agrees, then the balance.
- Save the transfer receipt with the clinic's invoice.

Cash: keep it small
Carrying large amounts of cash for a medical bill puts you at risk of theft and leaves you with no dispute rights. If you travel with more than $10,000 in currency, US law also requires you to report it when you leave or enter the country. Keep cash for taxis, tips, and small purchases.
A sensible payment sequence
- Deposit: credit card, after you've read the refund policy. See our guide to deposits and cancellation policies.
- Balance: card if the clinic accepts it without a steep surcharge; otherwise a verified transfer to the clinic's business account, ideally after your in-person consultation and clearance.
- Local expenses: no-fee card in local currency, plus a little cash.

Quick answers
Should I pay for surgery abroad in dollars or local currency?
Choose the local currency when paying by card. Paying in dollars at the terminal usually means the merchant's processor sets a worse exchange rate, and your card may still add a foreign transaction fee.
Is it safer to pay a clinic by credit card or wire transfer?
Credit cards generally offer dispute rights that wires and transfer services don't. Wires and transfers can be cheaper for large amounts but are hard to reverse, so verify the recipient carefully.
How do I avoid wire transfer scams when paying a clinic?
Pay only to an account in the clinic's legal business name and confirm the details by phone using a number from the official website. Treat any emailed change of bank details as a warning sign.
