Check registration to treat foreign patients
Korean law requires any medical institution treating foreign patients to register with the Ministry of Health and Welfare and to hold medical dispute insurance covering those patients. Registration is public and verifiable. A clinic that is not registered can still treat you legally as a walk-in, but you lose the insurance backstop and the dedicated coordination that registration implies. Ask for the registration status directly and treat evasion as an answer.
Confirm the specialist qualification, not just the licence
Every practising doctor in Korea holds a medical licence, but specialty certification is separate and is what distinguishes a board-certified plastic surgeon from a licensed physician performing cosmetic procedures. Both are legal. For surgery, look for certification by the relevant Korean specialty society, and for dermatology look for a board-certified dermatologist rather than a general practitioner running a skin clinic. Ask which named doctor will perform the procedure, since the doctor who consults is not always the one who operates.
Get an itemized quote before the deposit
A written quote should separate the professional fee, anesthesia, materials or implants, hospitalisation and aftercare. Bundled single-number quotes are where surprises live, particularly around anesthesia type and implant brand. If a procedure has a common add-on, such as ptosis correction with double eyelid surgery or bone grafting with a dental implant, ask explicitly whether the quote includes it.
Agree the follow-up schedule before you book flights
Almost every surgical procedure has a mandatory check at a fixed interval, and that interval, not the operation, determines how long you must stay in Korea. Suture removal at day five to seven, cast removal at day seven for rhinoplasty, a next-morning check after eye surgery. Ask for the schedule in writing and book the return flight around it rather than the other way round.
Understand what happens if something goes wrong at home
Complications usually appear after you have flown. Ask what the clinic covers if a revision is needed, whether they will correspond with a doctor in your own country, and what documentation you will receive at discharge. For implants of any kind, insist on the brand, model, size and lot number in writing, because your home clinician will need it.
Frequently asked questions
Do I need a medical visa to be treated in Korea?
Short treatments are commonly done on a normal tourist entry. A dedicated medical visa (C-3-3 for short stays, G-1-10 for longer treatment) is required for extended treatment and needs an invitation document from a registered medical institution or licensed agency.
Should I book through a medical tourism agency?
Not necessarily. Hospital international centers accept direct enquiries in English and arrange everything an agency would. Agencies add value for complex multi-department cases or uncommon languages. Only registered agencies may legally introduce foreign patients, so ask for the licence number and compare their quote against the clinic's direct price.
Is treatment in Seoul more expensive than elsewhere in Korea?
Generally yes, by roughly 10 to 30 percent for comparable procedures, with the Gangnam cluster at the top. Busan and Daegu offer established centers at lower prices, though with fewer English coordinators outside the largest hospitals.
