The South Korean Healthcare System: NHIS Health Insurance, Hospitals, Emergencies and Access for a Foreigner

The Korean healthcare system combines compulsory health insurance and medical aid for the least well-off. Three players share the roles: the Ministry of Health and Welfare sets policy, the NHIS runs the insurance, collects contributions and negotiates fees with establishments, and the Health Insurance Review & Assessment Service (HIRA) evaluates services. The NHIS is a single insurer: membership is compulsory for all residents, contributions depend on household income and assets, and establishments cannot refuse an insured patient.

Care is organised on two levels. First-line care is at a clinic or hospital; tertiary hospitals are reserved for specialised cases, with a referral letter from the doctor seen first. Establishments are public and private: the National Medical Center in Seoul and the Seoul National University Hospital are public institutions with international health centres. In April 2024, about 97% of the population came under health insurance and 3% under medical aid. The out-of-pocket share rises with the level of the establishment, a mechanism presented below.

Since July 2019, any foreigner who has resided in Korea for 6 months or more must be enrolled in the NHIS and receives the same benefits as a Korean, including hospitalisation, consultations, health check-ups and treatments. Conditions vary by profile:

• Employee of a covered employer: compulsory enrolment, declared by the employer from the start of employment, with no condition on length of stay. The contribution is 7.19% of salary in 2026, shared equally with the employer.
• Regional insured person (self-employed, retiree, unemployed): enrolment after 6 months of residence, with a contribution calculated by points on income and assets, to be paid before the 25th of each month. D-2 and D-4 students have been covered since March 2021; holders of a permanent resident visa (F-5) or spouse of a Korean visa (F-6) enrol on arrival. Diplomatic, tourist, short-stay and G-1 visas are excluded.
• Dependants: the spouse, direct ascendants and unmarried siblings can be attached if they meet income thresholds (less than 20 million KRW a year, about €13,200) and asset thresholds; the family tie is proved by documents authenticated by the Korean Ministry of Foreign Affairs, with Korean translation. Since 3 April 2024, enrolling a foreign dependant in principle requires 6 months of residence; for insured persons holding a D-2, D-4-3, E-9, F-5 or F-6 visa, minors under 19 and the foreign spouse are enrolled without this wait (Korea.net). Situations should be confirmed with the NHIS.

Exemption: the French embassy cites three categories that can request exclusion from the NHIS: seconded workers, CFE members and holders of recognised private insurance; the request is renewed every year. The NHIS specifies that the foreigner must prove equivalent cover, based on a foreign law, foreign insurance or an employer contract, and file the request within 14 days of the enrolment declaration. In case of late payment, the embassy reports benefits limited at hospitals and clinics, restrictions on visa applications or extensions and possible seizures on salary or assets. The page on healthcare reimbursement details each situation.

First-line care is at a clinic or hospital; access to a tertiary hospital goes through a referral letter if the patient’s condition calls for it. France Diplomatie observes that English-speaking doctors remain few, with the large hospitals of Seoul and a few establishments in the large cities offering international services. The National Medical Center thus offers an international health centre with interpretation in English, Chinese, Russian and Japanese and issuing of documents in English, and Seoul National University Hospital has a centre created in 1999 with English, Chinese, Mongolian, Russian, Arabic and Spanish interpreters (Korea.net).

Emergencies: 119 reaches the fire service and ambulance, 1339 medical emergencies and 112 the police. The Emergency Ready app, in English, makes it possible to call for help and locate medical emergency centres. A consular emergency line of the French embassy is reserved for immediate situations; routine questions go through the consular mailbox on weekdays. France Diplomatie reminds us that hospitalisation and health costs can be very high abroad and that the embassy does not pay them.

For outpatient care, the out-of-pocket share depends on the type of establishment: 30% at a clinic and a pharmacy, 40% at a hospital, 50% at a general hospital in an urban area (45% in a rural area) and 60% at a tertiary hospital. For hospitalisation, the co-payment is 20% of the cost, reduced to 5% for a registered cancer and to 10% for a rare or incurable disease. See the glossary entries on the co-payment and the out-of-pocket cost.

An annual ceiling limits cumulative co-payment: the NHIS publishes a table of ceilings from 870,000 KRW to about 8.26 million KRW (2025, or about €575 to €5,460), depending on the income decile and the length of hospital stay; dental implants are excluded from the calculation. Services not covered are billed to the patient in full. The contributions are described on the NHIS page: for an employee, 7.19% of salary in 2026, shared equally with the employer and due before the 10th of the following month; for a regional insured person, a score multiplied by a value of 211.5 KRW per point, with a minimum contribution equivalent to the average premium of foreign regional insured persons. Reductions of 10 to 50% exist for vulnerable groups and isolated areas. The conversions on this page rely on the ECB reference rate of 02/10/2026: 1,513.44 KRW per €1.

• Medicines: prescribed medicines are dispensed at a pharmacy with a 30% patient co-payment.
• Dental: dental care follows the co-payment principle by type of establishment; implants are excluded from the annual ceiling calculation.
• Maternity: the NHIS pays an allowance of 1 million KRW (about €660) per single-foetus pregnancy, increased for multiple births or underserved areas.
• Screening: the general health check-up is free; cancer screenings are covered at 90% by the NHIS, some with no patient co-payment.
• Optical: glasses and lenses are not among the benefits described by the NHIS; their cover is read in the benefits of a supplementary or international contract.

The guide to healthcare systems abroad places these mechanisms among those of other countries.

France Diplomatie recommends being up to date with the French vaccination schedule, notably diphtheria, tetanus, poliomyelitis, whooping cough and measles. Depending on the length and conditions of the stay, other vaccines may be added: hepatitis A, typhoid fever, rabies for young children and stays in rural areas, Japanese encephalitis for rural stays from May to October, tick-borne encephalitis in forest areas, tuberculosis for children under 15 on frequent or prolonged stays.

Mosquito-borne diseases (dengue, Japanese encephalitis and, in a few rural areas in the north, malaria) call for covering clothing, a repellent and protected housing. Fine-particle air pollution, increased in spring by the “yellow winds”, mainly affects the large cities and industrial regions: France Diplomatie advises reducing outdoor activities, staying hydrated and wearing a high-filtration mask, especially for children, older people, pregnant women and people with respiratory or heart conditions or asthma. The guide to living in South Korea completes these benchmarks on the climate.

The NHIS covers care in Korea, at national rates and with an out-of-pocket share. A resident who wants worldwide cover, direct access to international services, medical evacuation or repatriation can supplement it with the CFE or with international health insurance. The CFE and recognised private insurance also open the possibility of requesting exclusion from the NHIS, under the conditions recalled above. The pages expat health insurance and repatriation and assistance present these options; Expavy helps you weigh them against your situation.
