Korea's National Health Insurance Service (NHIS) rules matter mainly to foreign residents, students, and workers—not short-term tourists. Eligibility depends on employment, registered residence, visa status, length of stay, and any accepted exemption. Use this page as a starting map and ask NHIS for a decision on your own case.
Foreign employees
NHIS says foreigners and overseas Koreans working at an insured workplace are generally enrolled through that workplace. Contributions are based on monthly wages and are normally shared by employee and employer.
Exclusion may be possible in limited cases when equivalent coverage exists under foreign law, foreign insurance, or an employer contract. It is not automatic: NHIS requires an application and evidence, with deadlines applying to some requests. Ask both the employer and NHIS before assuming overseas coverage replaces Korean enrollment.
Residents not enrolled through work
Qualifying foreign nationals and overseas Koreans who have stayed in Korea for more than six months are generally subject to self-employed insurance enrollment, according to NHIS. Eligible residence status and visa-specific details still apply. This does not mean every visitor becomes insured after six months, or that a short-term tourist can use NHIS benefits.
What coverage means
Insured foreign nationals receive the same categories of National Health Insurance benefits as Korean citizens, subject to standard benefit and co-payment rules. National insurance does not make every treatment, medicine, elective procedure, or clinic service free.
Prepare your passport, residence card if applicable, visa type, employment details, Korean address, arrival date, and any foreign-insurance documents. Family documents for dependent registration may require authentication and a notarized Korean translation; confirm current requirements before paying for translation.
