Korean Medical Tourism Glossary: Visa, KAMI, KHIDI
Fifty-five medical-tourism terms I had to look up across six trips — visa categories, accreditation acronyms, attendant rules, refund language, and the agency-and-package vocabulary you'll see before you ever sign anything.
By my third trip to Seoul I had a folder on my phone called "M visa stuff" and a notes file called "acronyms I'm tired of Googling." KHIDI. KAMI. KIDI. KOFIH. MoHW. MFDS. C-3-3. M-1. M-2. The 90-day rule. 외국인환자 유치 등록업체 (which I copy-pasted into translator apps the first six times before I learned to read it). The vocabulary of Korean medical tourism is dense in a specific way — it's mostly government-registration language, visa-category language, and accreditation language stacked on top of the regular clinic vocabulary, and the documents that explain it tend to be either Korean-only or written in the kind of bureaucratic English that makes you tireder than when you started. The first time I tried to verify a clinic's foreign-patient registration I had four browser tabs open at the same time — the clinic's English page, the KHIDI portal, a Korean-English dictionary, and a translator app for the actual registration certificate which had been photographed and uploaded as an image rather than text. That was the moment I started writing things down. So I made a glossary. Fifty-two terms now, organized by what you'll actually need them for: visas and immigration, the registration system, accreditation acronyms, attendants and companions, agencies and packages, money and refunds, the stay infrastructure (recovery hotels, medical hotels, KIMS), and the post-treatment-back-home category that nobody warns you about until you're holding a Korean prescription at a US pharmacy counter trying to explain to the pharmacist what's in it. The book of acronyms can feel overwhelming on first read; in practice you only need maybe ten of these terms for a normal one-week non-surgical visit, and the other forty are for the longer recovery stays, the multi-trip plans, the surgical procedures, and the situations where a complication or refund question pulls you into the formal system. I'm not a lawyer, an immigration consultant, or licensed in anything — I'm a patient who's navigated the M visa or the 90-day stay rule across multiple trips and is putting the vocabulary in one place so you don't have to do the 2am Googling I did. None of this is legal advice. It's a phrasebook for the system you're about to enter.
“By trip three I had stopped Googling KHIDI in airport lounges. I knew what I'd booked, who held the registration, what the M-1 meant if I needed it, and which acronyms could be safely ignored. The vocabulary front-loads the work — and then the trips get easier.”

Frequently asked questions
I'm coming from the US for a 7-day non-surgical aesthetic clinic trip. Do I actually need an M visa?
Probably not. US passport holders enter Korea visa-free for stays up to 90 days under K-ETA, which covers most short aesthetic-clinic visits. The M visa adds value for longer recovery stays (post-surgery 4-8 weeks), multi-trip treatment plans where you're cumulatively bumping against the 90-day rule, or situations where you want to travel with an M-2 attendant under formal documentation. For a one-week non-surgical trip the visa-free entry is the cleaner path, and you can keep all the clinic registration verification (KHIDI, KAMI) on your end without involving immigration paperwork.
How do I actually verify a clinic's KHIDI registration before I pay them anything?
Go to khidi.or.kr/eng, find the medical-tourism section, and use the registered-provider search. Type the clinic's name in English (most large international-patient clinics will appear) and confirm the registration number on their site matches what you find on KHIDI. The format looks like A-2026-04-02-06873 — letter, year, month, sequence. If a clinic claims to accept international patients but doesn't appear in the KHIDI search and can't produce the registration number when asked, that's enough signal to walk. Reputable clinics display the number on their international-patient page voluntarily.
What's the actual difference between KHIDI registration, KAMI membership, and MERIT certification — are they all the same thing?
No, and the layered terminology is genuinely confusing the first few times you encounter it. KHIDI registration is mandatory and government-issued — without it, a clinic legally cannot market to or treat foreign patients. KAMI is voluntary industry-association membership — a self-organized group of clinics committed to international-patient practice; useful as one signal but not a regulatory floor. MERIT certification is a stricter government-affiliated accreditation specifically for facilities meeting elevated international-patient infrastructure standards — most relevant for hospital-tier facilities and surgical patients. JCI is global, third-party, and primarily for large hospitals. The mental model: KHIDI is the mandatory floor, KAMI is voluntary participation, MERIT and JCI are progressive ceiling credentials for higher-stakes contexts.
If I bring my mom on the trip as my attendant, does she need an M-2 visa?
Probably not for a 1-2 week aesthetic-clinic visit — she can travel under her own visa-free entry just like you, even though the clinic might list her as your 보호자 (attendant) on intake forms. The M-2 visa exists for situations where the attendant's stay specifically depends on their accompanying-person status — primarily multi-week surgical-recovery trips or cases where the attendant might cumulatively exceed visa-free limits. For a normal trip, your mom flies in on her own passport, the clinic notes she's your attendant, and that's the whole interaction. If the trip extends past 90 days or involves serious surgery, that calculus changes.
Will my US travel insurance cover anything that goes wrong with my Korean aesthetic procedure?
Almost certainly no. Standard US travel insurance excludes elective and cosmetic procedures explicitly — the exclusion language is in every plan's fine print. What travel insurance does cover for clinic patients is the unrelated emergency: you slip and break a wrist, you catch flu, your flight gets canceled and you miss the appointment. For procedure-related complications the financial exposure is on you. The realistic risk profile for Korean non-surgical 시술 at a registered clinic is low — Korea's safety record is strong and complications are rare — but "low risk" is different from "covered." Repatriation insurance is worth considering for multi-week surgical-recovery trips; for short non-surgical visits it's usually overkill.
Are referral agencies a scam, or are they legitimate, or somewhere in between?
Mostly somewhere in between. Korea regulates registered medical-tourism agencies under the same foreign-patient attraction law that covers clinics — legitimate agencies hold their own KHIDI registration and represent multiple registered clinics. The actual question is the financial transparency: how does the agency get paid (clinic-side commission vs patient-paid fee), which clinics are they actually able to recommend (the full registered universe vs the small subset that pays them), and whether the recommended clinic is also one you would have arrived at independently. For aesthetic-medicine patients booking with major Gangnam clinics, the value-add of an agency is often modest because the clinics themselves have well-developed international-patient infrastructure. For surgical or multi-procedure planning the agency's coordination function can be more useful. Ask directly which clinics they represent and what the fee structure is.
Why are US Medicare and most US health insurance not relevant for Korean clinic care?
Because both systems operate on territorial logic. Standard Medicare covers care received in the United States; coverage outside the US is extremely limited and excludes elective procedures entirely. Most US private insurance follows similar logic — it pays in-network providers in the US, and even out-of-network US care is usually covered at reduced rates rather than full denial. Korean clinics aren't in any US insurance network. The financial model for Korean medical tourism is paying out-of-pocket and treating Korean prices (which are often 30-60 percent of equivalent US aesthetic procedure prices) as the actual cost, not a covered benefit. Patients on Medicare assuming some portion of Korean care will be reimbursable usually discover otherwise after the fact.
Do I need to declare anything at US customs when I come home from Korea?
For most aesthetic-clinic trips, no. You're not bringing back medical devices, controlled substances, or biological materials. The medications you're prescribed (typically antibiotics, anti-swelling pills, mild pain relief) are usually in finished commercial packaging and in personal-use quantities, and the standard US customs declaration covers these without issue. The exception is controlled substances — sleep aids, stronger pain medications, some sedatives — which require both a copy of the Korean prescription and an English-translated doctor's letter. For routine non-surgical procedures this rarely applies. If you've had surgery and are on a controlled-substance regimen for recovery, ask the clinic to provide the customs documentation before you fly.
