South Korea runs a single-payer universal system, National Health Insurance, and it is mandatory. Foreign residents are generally required to enrol after staying more than six months — and some, such as students and certain workers, from arrival. Premiums are income-based, or assessed for those without employment income. The scheme covers a large share of medical costs and patients pay the remainder.
South Korea has a single-payer universal system, National Health Insurance (NHIS), which is mandatory. Foreign residents who stay more than six months are generally required to enrol (some, such as students and certain workers, from arrival), with income-based premiums. The NHIS covers a large share of medical costs; patients pay the remainder.

Find out when you must enrol
Foreign residents generally enrol after more than six months, but some — students and certain workers — from arrival. Establish which applies to you rather than assuming the six-month rule.
- 2
Register with the NHIS
Enrolment is handled by the National Health Insurance Service. Because the system is single-payer and mandatory, there is one route rather than a choice of insurers.
- 3
Understand how your premium is set
Premiums are income-based, or assessed for those without employment income. That means a student or non-earner is still assigned a contribution rather than being exempt.
- 4
Budget for the patient share
The scheme covers a large share of medical costs and patients pay the remainder. Coverage is broad but there is still a co-payment at the point of care.
- 5
Keep contributions current
Manage enrolment and contributions through the NHIS and keep payments current, since arrears can affect your coverage.
- Enrolment timing established (six months vs from arrival)

Frequently asked questions
When do foreign residents have to join Korea's NHIS?
Generally after staying more than six months, but some categories — students and certain workers — from arrival. Establish which applies to you, because assuming the six-month rule can leave you late for enrolment.
Do students without income pay premiums in Korea?
Premiums are income-based, or assessed for those without employment income — so a contribution is still assigned rather than waived. Budget for it as a recurring cost rather than expecting an exemption.
Can I choose my insurer in Korea?
No. National Health Insurance is a single-payer, mandatory system, so enrolment runs through the NHIS rather than a market of insurers. Private insurance exists but as a supplement, not an alternative.
