La santé à South Korea

Comment fonctionne le système

South Korea has universal health coverage delivered through a single mandatory social-insurance scheme, the National Health Insurance Service (NHIS), which the government runs as the sole national insurer. Roughly 97% of the population is covered by NHI (employee-insured ~68.5% and self-employed ~28.5% as of April 2024), with the remaining ~3% covered by the tax-funded Medical Aid program for low-income residents, so coverage is effectively universal. NHIS is financed mainly by income-based contributions (employee rate 7.19% in 2026, split 50/50 employer/employee) plus government subsidies, which makes it a social-insurance (Bismarck) model rather than a tax-funded national health service. Most hospitals and clinics are privately owned and operated but are paid by NHIS under a single national fee schedule. Patients pay cost-sharing at the point of care: typically about 20% for inpatient care and 30% to 60% for outpatient care, scaling up with facility tier (around 30% at a local clinic up to 60% at a tertiary general hospital), with exemptions/reductions for children under 6, people over 65, low-income groups and serious illnesses.

Service delivery is overwhelmingly private: over 90% of hospitals and clinics are privately owned, but they operate inside the NHIS single-payer framework and bill at regulated rates. "Private" insurance in Korea is largely supplemental — a majority of households buy private indemnity policies to cover NHIS co-payments, uninsured items (advanced diagnostics, some new drugs, private/upgraded hospital rooms, dental and cosmetic work). For a temporary resident or nomad who is not yet enrolled in NHIS (under the 6-month threshold or on a short-term/tourist visa), care is paid out of pocket at full price or via private travel/expatriate health insurance; out-of-pocket costs are moderate by international standards but the 119 ambulance is free while the subsequent hospital treatment is billed separately. Major Seoul hospitals (Severance, Asan, Samsung Medical Center, Seoul National University Hospital) run dedicated International Health Care Centers with English-speaking doctors, nurses and coordinators aimed at foreign and medical-tourism patients.

South Korea is widely regarded as a high-quality, high-access system: per-capita health spending is comparatively low (about USD 4,570 vs USD 13,432 in the US) yet it delivers strong access and among the highest life expectancy in the OECD, and medical bankruptcy is rare thanks to broad coverage. The main quality caveats are the concentration of advanced care in large urban hospitals (especially around Seoul) and out-of-pocket exposure from outpatient co-payments and uninsured items, which is why most households carry private supplemental cover. The spending figures come from a Physicians for a National Health Program summary of Korea's National Health Insurance Service that cites OECD data.
