Money on a Colombia Medical Trip: Cash, Cards and ATMs

Treat your money in two buckets. The big clinic payment should go by card or verified bank transfer, with a receipt for every peso. Day-to-day spending works best with a low-fee card plus a modest amount of cash in Colombian pesos (COP). Most of the money mistakes on medical trips come from mixing those two up: carrying surgical fees in an envelope, or paying hidden conversion fees on every coffee.

Clinic payments vs daily spending

These two kinds of spending need different tools, and the table below shows why.

For the clinic, the questions to ask in writing are simple. Which methods do you accept? Is there a surcharge for cards? When is each payment due: deposit, balance, any later follow-up? Is the quote in pesos or US dollars, and which exchange rate applies if they differ? And what document do I get for each payment? For more on comparing what a quote covers, see questions to ask a clinic before you book.

Set up your cards before you fly

A card blocked by your own bank's fraud system is the most common money problem for medical travelers. A large charge from a foreign clinic is exactly what those systems are built to stop. A short call or app session before you leave prevents most of it.

• Travel notice: tell each bank your dates and that you'll be in Colombia (some banks now do this automatically. Ask).
• Limits: if you'll pay the clinic by card, ask for a temporary higher limit, or confirm the payment will go through on the planned day.
• Fees: ask for the foreign transaction fee and the ATM fee on each card. Some cards charge neither, others charge both.
• Two networks: bring cards on at least two networks (for example Visa and Mastercard) in case one is down or refused.
• A backup: one spare card that you never carry with your main one.
• Contact numbers: save your bank's international phone number. A toll-free number may not work from abroad.
• 2FA access: make sure you can still receive bank codes in Colombia. If they come by text message, keep your home SIM active (or switch the bank to app-based approval) before you leave.

Using cards in Colombia

In the parts of Medellín, Bogotá and Cali where most visitors stay, cards are widely accepted at supermarkets, pharmacy chains, restaurants and malls. Small neighborhood shops, market stalls, some taxis and tips are more often cash. A few things are different from home:

"¿A cuántas cuotas?"

Colombian card terminals often ask how many installments (cuotas) to split a credit purchase into. That's a feature for Colombian credit cards. With a foreign card, just say "una" (one).

Choose pesos, not your home currency

A terminal or ATM may offer to charge you in US dollars, euros or pounds "for your convenience." That's dynamic currency conversion, and the rate it uses is often worse than your own card network's. Pick pesos (COP) and let your bank convert.

The card stays in sight

Staff usually bring a portable terminal (datáfono) to your table. That's normal and lets you keep your card in sight, which is good practice anywhere.

You may be asked for ID

Some places ask for your passport number or a copy of it for card payments. Having a photo of your passport's data page saved on your phone keeps this quick.

ATMs: getting cash with less friction

Colombian ATMs (cajeros) usually charge foreign cards a per-withdrawal fee, on top of whatever your bank charges, and limit how much you can take out at once. Both vary by bank and change over time, so check the screen before you confirm.

1. Use ATMs inside banks, malls or supermarkets, during daytime, rather than street-facing machines at night.
2. Withdraw fewer, larger amounts (within what you're comfortable carrying), since fees are usually per withdrawal.
3. Decline conversion if the ATM offers to bill you in your home currency.
4. Cover the keypad and check the card slot looks normal before inserting.
5. Put the cash away before you walk out, not on the street.
6. Don't let a stranger "help" if the machine misbehaves. Cancel and use a different one.

Carrying cash safely while you recover

You'll want some pesos for taxis, small pharmacy runs, tips and snacks. You won't want a thick wallet. A few habits help:

• Day money only: carry what you need for today. Leave the rest in your accommodation's safe or locked luggage.
• Split it: keep a small amount in a different pocket from your main wallet.
• Small notes: drivers and small shops may not have change for large bills. Break big notes at supermarkets.
• Phone discretion: using your phone at the curb is how a lot of phones get snatched in big cities. Step inside to check maps or messages.
• Book rides through apps or your clinic or hotel rather than hailing on the street, especially at night. Our guide to getting around after surgery covers this.

Colombia requires travelers carrying more than US$10,000 (or the equivalent) in cash to declare it to customs (DIAN) when entering or leaving. Even below that, flying in with a large cash amount to pay a clinic is a risk you don't need to take.

Deposits and wire transfers: fraud cautions

Many clinics ask for a deposit to hold a surgery date, and some ask for it by international bank transfer. Transfers are legitimate and common. They're also nearly impossible to reverse once sent, which makes them the favorite tool of payment fraud. The basic precautions:

• Verify by phone. Before you send money, call the clinic on a number from its official website (not from the email asking for payment) and confirm the account details out loud.
• Treat changed details as a red flag. "Our bank account has changed, please use this one instead" by email or chat is a classic interception scam. Stop and verify by phone.
• Match the names. The account holder should be the clinic or company you're contracting with. Be very cautious about paying a personal account, or a "coordinator" you can't independently connect to the clinic.
• Get the terms first. Ask for the deposit's refund and rescheduling terms in writing before you pay.
• Send a small test first if you're unsure, and confirm the clinic received it.
• Ask for a receipt for the deposit, and keep the bank's transfer confirmation.

Pressure is a warning sign of its own. "The discount ends tonight" or "only one slot left, pay now" is not how a careful medical provider should be running your care.
