When a surgery quote arrives from a clinic in Medellin, it is in Colombian pesos. A quote from Monterrey is in Mexican pesos. Bangkok bills in Thai baht, Istanbul in Turkish lira. Reading these quotes requires more than dividing by the exchange rate, because the exchange rate you see on Google is not the rate you pay, and the timing of the conversion affects the total by 3% to 8%.
The rates that matter
| Rate Type | What It Is | Where You See It |
|---|---|---|
| Mid-market rate | The "real" exchange rate between two currencies with no markup | Google, XE.com, Reuters |
| Card rate | Your credit or debit card's conversion rate, typically 1-3% above mid-market | Your bank statement after you pay |
| Wire transfer rate | Your bank's rate for outgoing international transfers, typically 2-5% above mid-market plus a flat fee ($25-$50) | Your bank's wire transfer form |
| Wise rate | Near mid-market rate with a transparent fee of 0.4-1.5% | wise.com |
| Cash exchange rate | The worst rate, 4-8% above mid-market at airport kiosks, 2-4% at city exchange houses | Exchange booths and airports |
A worked example
Suppose a clinic in Medellin quotes a tummy tuck at 18,000,000 COP (Colombian pesos). Here is what that costs in US dollars depending on how you pay, assuming a mid-market rate of 4,200 COP per USD:
Same Quote (18M COP), Different Payment Methods
18,000,000 COP at mid-market 4,200 COP/USD = $4,286 base. Figures illustrative; actual rates fluctuate daily.
The difference between the best and worst payment method on the same quote is $530, or roughly 12%. On a larger procedure quoted at 50M COP, the gap widens to $1,400 or more.
What to ask the clinic
- Is the price locked in the local currency or in USD? Some clinics quote in USD and absorb the exchange risk. Others quote in local currency and the patient absorbs the fluctuation.
- When is payment due? If you pay a deposit 60 days before surgery and the balance on arrival, the exchange rate may be different on each date. Ask whether the clinic honors the rate at the time of the quote or the rate at the time of payment.
- Which payment methods does the clinic accept? Some clinics accept Wise transfers directly. Others require bank wires or cash only. A clinic that only accepts cash in local currency is steering you toward the worst exchange rate.
- Is there a credit card surcharge? Some clinics add 3% to 5% for credit card payments, which eliminates any credit card rewards benefit.
The Wise strategy
For medical travel payments, Wise (formerly TransferWise) consistently offers the lowest total cost for international transfers. It uses the mid-market rate and charges a transparent fee of 0.4% to 1.5% depending on the currency pair and payment method. You can lock the rate at the time of transfer, eliminating the risk of fluctuation between booking and payment. Many clinics in Colombia, Mexico, and Thailand accept Wise transfers directly to their local bank accounts.
