Talk to enough foreigners living in Korea, and the same story comes up.
You feel sick. You have no idea where to go.
The signs on every corner say uiwon, byeongwon, jonghap byeongwon — and they all look like they just mean "hospital." They don't. Korea draws hard legal lines between these categories. Walk into the wrong one, and you burn both time and money finding that out.
Today I want to lay out that structure, so the next time you're sick, you're not guessing.
Quick Answer
- Korean medical facilities fall into four tiers: clinic → hospital → general hospital → tertiary hospital, ranked by bed count and treatment scope.
- For anything minor — a cold, an upset stomach — start at a clinic. No appointment needed, and it's the cheapest option by far.
- Tertiary hospitals handle severe and complex disease. Show up without a referral letter and you're not classified as an emergency case — your insurance won't apply, and you pay the full bill yourself.
- In an actual emergency, call 119. It's free, and as of a recent rollout, it now offers text-based reporting, video calls, and three-way interpretation for foreign residents.
- Worried about the language barrier? BBB Korea (1588-5644) offers free phone interpretation in 20 languages. You only pay the call charge — the interpretation itself costs nothing.
- Want to be seen in English without the guesswork? Major hospitals like Severance, Samsung Medical Center, Seoul National University Hospital, and Asan Medical Center run dedicated International Health Care Centers.
1. Korea's Four-Tier Hospital System
Korean medical facilities are legally split into four tiers, defined by bed count and the scope of care they're licensed to provide.
Tier Bed Count What It Is When You Go
| Clinic (uiwon) | None — outpatient only | Small neighborhood practice | Colds, minor symptoms, everyday care |
| Hospital (byeongwon) | 30+ beds | Small-to-mid facility, admits patients | Symptoms serious enough to need admission |
| General Hospital (jonghap byeongwon) | 100+ beds | Multiple departments, specialists on staff | Cases needing coordination across departments |
| Tertiary Hospital (sanggeup jonghap byeongwon) | A certified subset of general hospitals | Certified for high-difficulty treatment of severe disease | Cancer, cardiac conditions, complex or rare disease |
The recommended flow is straightforward. Minor symptoms start at a clinic. Anything needing closer testing or admission moves up to a hospital or general hospital. Severe disease goes to a tertiary hospital.
Here's the advice I give every foreign friend who asks me this: don't start at the biggest hospital you can find. Korea has no registered "primary care doctor" system the way the US or UK does. You just walk into any clinic, no appointment, no assigned doctor. That's the fastest, cheapest place to start, full stop.
2. Tertiary Hospitals Require a "Referral Letter"
This is where a lot of foreigners get tripped up. The instinct is: "I should just go to the best, biggest hospital" — and they head straight for a tertiary hospital.
Here's the problem. Show up at a tertiary hospital without a referral letter, and unless you're classified as an emergency case, your insurance doesn't apply. You're on the hook for the full bill yourself.
- A referral letter is a document from a clinic or hospital stating: "this patient needs the specialized care a tertiary hospital provides."
- With that letter in hand, your national health insurance coverage applies normally.
- Get classified as an emergency case, and insurance kicks in even without a referral letter.
- One more wrinkle: if you were already treated for Condition A and now need tertiary-hospital care for a separate Condition B, you need a new referral letter specific to Condition B.
Bottom line: a tertiary hospital isn't a place you casually walk into. It's a destination you reach through a defined path.
3. In an Emergency: Just Call 119
If it's genuinely urgent, don't overthink it. Call 119.
- An ambulance is free.
- A newer multi-channel reporting system now supports text-based reporting, video calls, and three-way interpretation specifically for foreign residents in emergencies.
- Even without shared language, an interpreter can be brought in to relay what's happening.
(A note for anyone reading older guides: there used to be a separate emergency medical hotline, 1339. That's been folded into 119. If you see 1339 mentioned somewhere, know that the number to actually call now is 119.)
4. Beating the Language Barrier: Free Interpretation
Even outside an emergency, communication at a neighborhood clinic can hit a wall. There's a free service built for exactly that.

BBB Korea Phone Interpretation
- Domestic number: 1588-5644
- Supports 20 languages — English, Chinese, Japanese, Vietnamese, Thai, Russian, Arabic, and more.
- The interpretation itself is free. You only pay for the phone call.
- You can use it right at the clinic's reception desk or in the exam room. One caveat: it covers interpretation only — it won't negotiate costs or handle bookings on your behalf.
Install the app, verify your phone number, and you can request an interpreter directly. No app? Just call the main number.
5. Want English-Language Care? International Health Care Centers
If you'd rather remove the communication problem entirely, major hospitals run dedicated International Health Care Centers.
Severance Hospital, Samsung Medical Center, Seoul National University Hospital, and Asan Medical Center — among Korea's largest hospitals — each operate a center specifically for foreign patients. English-speaking coordinators handle everything from booking to the visit itself to payment.
One thing worth remembering: these centers mostly sit inside tertiary hospitals. That means the referral letter rule from Section 2 still applies. If you're dealing with something minor and want to use an International Health Care Center anyway, getting a referral letter from a regular clinic first is the safer move financially.
6. Getting Your Medication at the Pharmacy
After you see a doctor, you'll usually leave with a prescription. That prescription goes to a pharmacy (yakguk) — a separate stop.
- Prescription medications require you to hand over the prescription. No exceptions.
- Over-the-counter items — cold medicine, digestive aids — can be bought directly at the pharmacy, no prescription needed.
- Hospitals and pharmacies are separate businesses in Korea. Remember that your visit isn't finished until you've made that second stop.
FAQ
Can I just walk into any hospital without an appointment? Clinics, mostly yes. Tertiary hospitals and popular specialties often require an appointment, or come with a long wait even with one.
When should I actually go to the ER? When it's life-threatening or needs immediate treatment. Using the ER for a minor cold means a longer wait and a higher bill than a clinic visit would.
What happens if I go to a tertiary hospital without a referral letter? Unless you're classified as an emergency case, insurance won't apply, and you pay the full cost of treatment yourself.
What if nobody at the hospital speaks English? Call BBB Korea (1588-5644) for free interpretation, or use an International Health Care Center at one of the major hospitals.
What to Do Next
Korea's hospital system has clear tiers. Know the structure ahead of time, and being sick costs you far less time and money.
Three things worth doing right now:
- Find a clinic near where you live before you need one — so you're not searching mid-emergency.
- Save BBB Korea's number (1588-5644) in your phone.
- Remember: in an emergency, it's 119 now — not 1339.
TL;DR
- Korean hospitals split into four tiers — clinic, hospital, general hospital, tertiary hospital — and minor symptoms should always start at a clinic.
- Tertiary hospitals require a referral letter for insurance to apply, unless you're classified as an emergency case.
- Emergencies go through 119, and the language barrier has a free fix: BBB Korea's interpretation line at 1588-5644.
