Visiting a Hospital in Korea: Clinics, Referrals and What You Pay

The system is tiered, and the tier decides the cost

Korean medical institutions are graded, and where you walk in changes both the wait and the bill.

Type	Korean term	Typical use
Clinic	uiwon (의원)	First stop for common illness, minor injuries
Hospital	byeongwon (병원)	Inpatient capacity, broader departments
General hospital	jonghap byeongwon (종합병원)	Wide range of specialties
Tertiary hospital	sangdeup jonghap byeongwon (상급종합병원)	Referral-based, complex and serious conditions

The referral rule

To have national health insurance apply normally at a tertiary hospital, you generally need a referral (jinryo uiroeseo, 진료의뢰서) from a lower-tier institution. Arriving without one means paying a substantially larger share yourself.

This is the single most expensive mistake newcomers make. The instinct — go to the biggest, best-known hospital — produces a much larger bill and a much longer wait than starting at a neighbourhood clinic.

Emergency departments are an exception. Genuine emergencies do not require a referral. For emergencies call 119, which dispatches ambulances and fire services.

How to start

For a sore throat, a rash, a persistent cough or a minor injury, find a local uiwon with the relevant specialty on its sign — internal medicine (naegwa, 내과), ENT (ibiinhugwa, 이비인후과), dermatology (pibugwa, 피부과), orthopaedics (jeonghyeong-oegwa, 정형외과). Walk-in is normal; appointments are often unnecessary at clinic level.

What it costs

With National Health Insurance

If you are enrolled — as an employee subscriber through work or as a local subscriber — insurance covers a large share of the cost of covered treatment. A routine clinic consultation typically leaves you paying a modest amount at the desk. The proportion you pay rises with the tier of institution, which is another reason to start at a clinic.

Without insurance

You pay the full amount. This varies widely between institutions and can be many times the insured cost for the same consultation. Short-term visitors and those in the waiting period before enrolment face this.

What insurance does not cover

Even when enrolled, some things fall outside coverage (bigeupyeo, 비급여):

• Cosmetic procedures
• Some dental work
• Certain advanced imaging and tests, depending on indication
• Some newer treatments and medicines
• Private room supplements

Bills often mix covered and uncovered items. If a large uncovered charge appears, it is reasonable to ask before treatment what will and will not be covered.

Enrolment for foreign residents

Enrolment requirements apply to foreign residents meeting the criteria. Where you are a local subscriber rather than covered through an employer, premiums are assessed under rules that cannot see overseas income and assets, which produces a minimum premium that some find disproportionate to their Korean income. Students and freelancers meet this most often.

Confirm your position with the National Health Insurance Service rather than assuming. Being uninsured in Korea is not catastrophic for a minor illness but becomes very expensive for anything requiring admission.

Travel insurance is not a substitute for enrolment if you are a resident, though it may cover you during a waiting period. Check what your policy actually pays and whether it requires you to pay upfront and claim later.

Pharmacies are a separate stop

Korea separates prescribing from dispensing. The doctor prescribes; a pharmacy (yakguk, 약국) dispenses. You will almost always make two stops and two payments.

How it goes

1. Consultation at the clinic
2. Pay the clinic
3. Receive a prescription (cheobangjeon, 처방전) — usually two copies
4. Take it to a pharmacy, typically within a few minutes’ walk
5. Pay the pharmacy separately

Pharmacies cluster around clinics for this reason. The prescription has a validity period, so fill it promptly.

Over-the-counter medicine

Basic remedies — painkillers, cold medicine, digestive aids, plasters — are available at pharmacies without a prescription. A limited set of common medicines is also sold at convenience stores outside pharmacy hours.

Bring your own medication carefully

Some medicines that are ordinary elsewhere are controlled or prohibited in Korea, including certain ADHD medications, strong painkillers and some sleep aids. Bringing them without the correct documentation can cause serious problems at the border.

If you take prescription medication regularly:

• Check its status before travelling
• Carry your prescription and a doctor’s letter
• Where required, obtain advance approval from the Ministry of Food and Drug Safety

Repeat prescriptions are not transferred from overseas. A Korean doctor will assess and prescribe independently, and the equivalent medicine may differ in name, dose or availability. Bring documentation of what you take so the consultation starts from accurate information.

Finding care in a language you understand

International healthcare centres

Major hospitals in Seoul and other large cities operate international clinics or foreign patient services with staff who speak English and often other languages. They coordinate appointments, interpretation and billing. Cost may be higher than a neighbourhood clinic, but for anything complex the clarity is worth it.

Interpretation services

• 1339 — the health information call line, which handles medical enquiries
• 120 Dasan Call Centre in Seoul, with interpretation for city services
• BBB Korea — a volunteer telephone interpretation service
• Some hospitals arrange interpreters if booked in advance

Practical preparation

• Carry your alien registration card and insurance details
• Write down your symptoms, duration and current medications before going. Consultations are often brief, and having the facts ready changes the quality of the outcome.
• Note allergies and previous surgeries
• Ask for the diagnosis name in writing if you may need to follow up or claim on insurance

Emergencies

• 119 — ambulance and fire. Interpretation support is available.
• Emergency departments operate around the clock at general and tertiary hospitals
• Emergency care does not require a referral

If you are unsure whether a situation is an emergency, 1339 can advise, and 119 will not refuse a call because the situation turns out to be minor.

Dentistry and optometry are largely separate. Dental work is often uncovered or partly covered; glasses and contact lenses are bought at optician shops without a prescription requirement.
