Korean medical bills are genuinely cheap for routine care and genuinely expensive when they’re not. Understanding why — and knowing exactly which services are covered versus not — prevents unexpected bills and helps you use the system effectively. This guide explains how Korean medical cost-sharing works, where the price jumps happen, and what to expect at different types of facilities.
1. The Core System: Cost-Sharing Rates
Korea’s National Health Insurance (NHIS) covers a defined set of medical services. For covered treatments (급여 항목), you pay a percentage of the official fee — the rest is covered by NHIS. For non-covered treatments (비급여 항목), NHIS pays nothing and you pay 100%.
Standard cost-sharing rates for covered treatments by facility type:
| Facility Type | Your Share (Covered Treatments) |
|---|---|
| Local clinic (의원) — first visit | 30% |
| General hospital (병원, under 100 beds) | 40% |
| Hospital (종합병원, 100–500 beds) | 50% |
| Tertiary hospital (상급종합병원) without referral | 60% |
| Tertiary hospital with referral | ~20–30% (reduced with proper referral letter) |
| Emergency room | Varies by reason; 20–50% |

The practical implication: a consultation fee at a local clinic might total ₩15,000–25,000 — you pay ₩4,500–7,500. A consultation at Samsung Medical Center or Asan Hospital without a referral letter triggers the 60% rate on a higher base fee.
2. Why Routine Visits Are So Cheap
A typical local clinic visit in Korea:
- Consultation fee (진찰료): ₩15,000–22,000 base → your 30% share: ~₩4,500–6,600
- Common blood test panel: ₩30,000–60,000 total → your share: ~₩9,000–18,000
- Common prescription (3–5 days supply): ₩2,000–5,000 at the pharmacy
- Total for a typical illness visit: ₩10,000–25,000
Compare this to equivalent visits in the US (uninsured: $200–400+), UK private (£100–200), Australia (bulk-billed = free, but not always available), or Singapore ($80–200). For expats from expensive healthcare systems, Korean routine care is a genuine financial benefit.
3. Where Costs Jump: Non-Covered Treatments (비급여)
비급여 (non-covered) items are set at the hospital’s discretion — no NHIS price cap, no cost-sharing. You pay 100% of whatever the facility charges. Common non-covered treatments that surprise expats:
- MRI (most types): ₩200,000–600,000 depending on body part and facility. Some MRIs are now covered (brain, spine for specific indications); others remain non-covered. The coverage boundary has been expanding but is still inconsistent.
- CT scan: Better covered than MRI; most CTs with clinical indication are covered at 30–50% share
- Manual therapy and chiropractic: Generally non-covered at most facilities
- Aesthetic procedures: All cosmetic procedures (filler, Botox, laser, rhinoplasty) are non-covered — this is the largest category of 비급여 in Korea by volume
- Dental (general): Most dental treatment is non-covered — fillings, crowns, implants, orthodontics are paid out-of-pocket. Exceptions: scaling (teeth cleaning) once per year is covered, and dental X-rays for some indications
- Vision/glasses/contacts: Vision correction and corrective lenses are not covered. LASIK is non-covered.
- Certain injections and drips: Vitamin IV drips (popular in Korean clinics), some joint injections — non-covered
- Premium hospital rooms: Private rooms above the standard covered ward rate — the upgrade is non-covered
4. The Referral System and Why It Matters
Korea’s tiered hospital system is designed to funnel routine cases to local clinics (의원) and only move complex cases to large hospitals. Without a referral:
- Visiting a tertiary hospital (상급종합병원 — Samsung, Asan, Severance, SNUH) directly: 60% cost-sharing on covered items, plus a significant additional surcharge (상급종합병원 외래진료비 본인부담)
- With a referral letter from a local clinic: cost-sharing drops significantly and you get faster specialist access
For expats: see a local clinic first for non-emergency issues. Get a referral (진료의뢰서) if specialist care is needed. The cost difference is substantial and waiting times at smaller clinics are much shorter.
5. Catastrophic Cost Protections
Korea has a patient out-of-pocket ceiling to prevent catastrophic healthcare debt:
- Annual out-of-pocket maximum (본인부담 상한제): Varies by income — for average-income households, the cap is approximately ₩1,500,000–3,000,000/year on covered treatments. Above the cap, NHIS refunds the excess. Source: National Health Insurance Service (NHIS, 국민건강보험공단), 2025 Health Insurance Statistical Yearbook
- This cap applies only to covered (급여) treatments — 비급여 costs are excluded from the calculation
- For serious illness involving hospital stays: covered treatment costs are almost always manageable due to the cap system
6. International Medical Tourism in Korea
Korea is a significant medical tourism destination, which creates a parallel private/international medicine market in Seoul:
- International clinics and medical tourism services (Korea Medical Tourism Council) charge significantly higher rates for English-language services
- Some foreigners pay 비급여 international rates for convenience; others use the standard NHIS system and pay the same rates as Korean nationals
- If you’re enrolled in NHIS, you have full access to the standard system — use it rather than defaulting to expensive international clinics unless you have a specific reason
7. Dental in Korea: A Separate System
Dental costs deserve specific mention because they’re a consistent source of bill shock:
- Simple filling: ₩50,000–150,000 (non-covered)
- Root canal + crown: ₩500,000–1,200,000 per tooth (mostly non-covered)
- Implant: ₩1,200,000–2,000,000 per tooth (partially covered for patients 65+ for up to 2 implants; non-covered under 65 in most cases)
- Orthodontics (braces): ₩3,000,000–6,000,000 (non-covered)

Dental costs in Korea are cheaper than comparable out-of-pocket costs in the US or UK, but they’re a significant non-covered expense. Private dental insurance (available through Korean insurers) can offset this.
Frequently Asked Questions
Q: I went to a local clinic, then was referred to a hospital for surgery. My bill was much higher than expected. Why?
A: Hospital inpatient costs have higher cost-sharing rates than outpatient clinic visits. Additionally, surgical procedures often involve a mix of covered and non-covered components — the covered procedure may be cheap, but anesthesia type, specific surgical materials, or room choice may be non-covered. Ask for a 비급여 breakdown (비급여 진료비 확인서) before any planned procedure.
Q: Can I get a bill in English?
A: At major international hospitals (SNUH, Samsung, Severance) yes — they have international patient desks that provide English-language billing. At local clinics, usually not. Google Translate on the receipt is usually sufficient to identify the main items.
Q: Is there any benefit to paying into Korean private insurance on top of NHIS?
A: Yes — “실손보험” (Silseon, actual expense insurance) covers a portion of your 비급여 costs including many that NHIS doesn’t touch. It’s sold by Korean insurers (Samsung Life, Hanwha, etc.) and is widely held by Korean residents. For expats staying long-term, it’s worth considering.
