You’ve picked your hospital, gotten your quote, and now someone in the international-patient office has emailed you a bank account number and asked for a deposit. This is the part of medical tourism nobody warns you about: the mechanics of actually getting money from your bank account in Lagos, Dubai, Manila, or Nairobi into a Korean hospital’s KRW-denominated account without losing 5-8% to fees and exchange-rate spread, or having the payment bounce two days before your flight.
Why This Trips People Up
Korea’s Foreign Exchange Transactions Act treats inbound medical-purpose remittances differently from a routine personal transfer. Korean banks — KB Kookmin, Woori, Shinhan, KEB Hana — are required to record a “purpose of remittance” code on every incoming international wire above a reporting threshold, and medical treatment has its own code separate from “family support” or “travel.” If your sending bank fills in the wrong purpose code, or the beneficiary name on your wire doesn’t exactly match the name on the hospital’s account (down to spacing and capitalization), Korean banks routinely hold the funds for manual review — sometimes 3-5 business days — while your surgery date sits unconfirmed.
Hospitals with mature international desks (Samsung Medical Center, Asan Medical Center, Severance Hospital’s international health care center) know this and will hand you a pre-filled remittance instruction sheet with the exact beneficiary name, SWIFT/BIC code, account number, and — critically — a reference code tied to your patient file that must appear in the wire’s “message to beneficiary” field. Smaller clinics booking through a broker sometimes don’t, which is its own red flag (see our guide on spotting unlicensed facilitators).
The Three Ways Money Actually Moves
1. Traditional bank-to-bank SWIFT wire. Your bank sends via SWIFT to the hospital’s Korean bank, usually routed through one or two correspondent banks in between. Expect: an outgoing wire fee from your own bank (commonly $15-50 or the equivalent), a correspondent-bank handling fee deducted somewhere in transit that you don’t see coming (this is the “missing $20-40” people find when the hospital confirms a smaller amount arrived than they sent), and an FX conversion spread — banks typically mark up the mid-market exchange rate by 2-5% on a standard wire, more for less-traded currency pairs like Nigerian naira or CFA franc. On a $10,000 procedure deposit, that spread alone can be $200-500.
2. Multi-currency fintech transfer (Wise, Revolut Business, similar). These route as local transfers on both ends rather than a true SWIFT wire, which is why the FX spread is usually under 1% and fees are flat and disclosed upfront. The catch: not every corridor is supported to Korean won, and Korean banks are more likely to flag an incoming transfer from a fintech’s Korean banking partner for manual purpose-of-payment review than one from a well-known correspondent bank, because the sender-of-record on the Korean side is the fintech, not your own bank. Call the hospital’s international desk before using this route and confirm they’ve received payments this way before.
3. Card payment or hospital-hosted payment link. A growing number of hospitals now offer a Stripe- or PG-backed card payment link for deposits under a certain amount (often capped around $3,000-5,000 equivalent, since card-network fees on larger medical payments get expensive fast for the hospital). Fastest option, worst exchange rate — your card issuer’s cross-border FX fee (typically 1-3%) stacks on top of whatever markup the payment processor applies. Use this for a small confirmation deposit, not the full treatment cost.
The Double-Conversion Trap
If you’re paying from a country whose currency isn’t directly quoted against the Korean won — several African and GCC currencies fall into this bucket — your money may get converted twice: once from your local currency to USD or EUR, then again from USD/EUR to KRW. Each conversion carries its own spread. A patient wiring from a West African account through a correspondent-bank chain can lose 6-9% cumulatively to two conversions plus fees, versus 1-2% through a single-conversion multi-currency platform that quotes your currency directly against KRW. Ask your sending bank explicitly: “does this wire convert once or twice before it reaches Korean won?” Most bank staff can answer this if asked directly, even though it’s never volunteered.
What to Confirm Before You Send Anything
- Exact beneficiary name match. Get the account holder name in writing from the hospital and copy it character-for-character into your wire instruction — Korean hospital accounts are frequently held under a foundation or medical-corporation name (e.g., “Samsung Medical Center” is technically under the Samsung Life Public Welfare Foundation for some transactions) that doesn’t match the hospital’s public-facing name.
- The reference/message field. If the hospital gave you a patient ID or quote reference number, it belongs in the wire’s reference field, not just the email thread. This is what lets the hospital’s finance office match your payment to your file without a delay.
- Purpose-of-payment code. Confirm with your own bank that they’re coding it as medical treatment, not “gift,” “family support,” or generic “other.” The wrong code is the single most common cause of a held wire on the Korean receiving end.
- A same-day confirmation ask. Request that the international coordinator confirm receipt the same business day funds should land (Korean banks generally process incoming SWIFT wires same-day if they arrive before early afternoon KST) — don’t wait three days to ask “did it arrive,” because if it didn’t, you want to know while you can still fix it before your travel date.
