Mandatory National Health Insurance for foreign residents - enrolment, monthly premiums, coverage and dependants.
Enrolment in Korea's national health scheme is an obligation, not an option, and for most foreign residents it begins once you pass six months in the country. Employees are usually enrolled from their first month through work instead.
Two things about it cause real trouble, and both are avoidable: how your premium gets assessed, and what happens if you let it fall behind.
There are two routes in, and which applies to you changes what you pay.
Through your workplace. If you are employed, enrolment is handled by your employer from the start of the job, and the premium is split between you and the employer. It comes out of payroll and you do very little. This is the better position by a wide margin.
As a local subscriber. If you are not employed - a student, a dependant, self-employed, between jobs - you are enrolled in your own right once you pass the residence threshold, and you pay the whole premium yourself, billed monthly.
Enrolment as a local subscriber is generally automatic rather than something you apply for, and the first bill arriving unexpectedly is a common surprise. It is not a mistake.
For a workplace subscriber the premium is a percentage of your salary, shared with your employer. Straightforward.
For a foreign local subscriber it is not. Where income and property inside Korea cannot be properly assessed, the scheme can apply a benchmark figure based on the average subscriber instead of your actual means. The practical consequence is that a low earner can pay more than a Korean neighbour on a similar income, which is a long-standing and well-documented grievance.
Check how yours was assessed rather than assuming it is correct. If you have documentation of a genuinely low income, or your circumstances changed, take it to a local office. Reductions and exemptions exist in defined situations, including for some students and for certain hardship cases, and they are not applied automatically.
You can usually register a spouse and children living in Korea as dependants on your own cover rather than paying separate premiums, provided the relationship and income conditions are met.
| Who qualifies | Spouse, children, and in some cases parents, resident in Korea |
| What you need | Authenticated and translated marriage and birth certificates |
| What it costs | Generally no additional premium for a qualifying dependant |
| What to watch | A dependant with their own income above the limit must enrol separately |
The documents are the obstacle, not the rule. Authentication starts in the country that issued the certificate, so order spare certified copies once. Family and marriage covers that chain.
Students are inside the scheme rather than outside it, and the arrangement has changed in recent years, so this is one to confirm with your international office in your first weeks rather than assume.
Two things generally hold. A reduced rate applies to foreign students compared with other local subscribers, which is a meaningful difference on a student budget. And the enrolment is handled against your registration at the institution, so your international office will know the mechanics and the billing date.
What catches students is the gap: if you arrive and are not yet enrolled, you are uninsured, and a single unplanned admission costs more than a year of premiums. Carry travel or private cover until the scheme picks you up. International students covers the wider first-year sequence.
A broad range of outpatient, inpatient and prescription care, with you paying a modest share and the scheme paying the rest. Dental, vision and anything cosmetic are largely outside it, which is why supplementary private insurance is common in Korean households.
The gap between an insured and an uninsured bill is the whole reason this matters. Medical and health covers using the system, and making an insurance claim covers claiming.
This is the sentence to remember. Unpaid premiums can block a visa extension.
Arrears are not a billing dispute you can defer until it suits you. They are checked, and a straightforward renewal becomes a refusal over a few months of missed payments. Non-payment can also suspend your entitlement to benefits, so you pay full price at the hospital while still owing the premiums.
The fix is dull and complete: set up automatic debit the moment your bank account works. Banking covers it. If you are already behind, go to a local office and ask about an instalment arrangement rather than waiting.
In your first six months as a non-employee you are outside the scheme, so carry travel or private cover for that window. An uninsured hospital admission is the expensive scenario this bridges.
When you leave Korea, deregister rather than simply stopping payment, or billing continues against your registration number. If you have overpaid you can claim it back, and if you have been employed there is a separate question about your national pension contributions, which may be refundable or transferable depending on your nationality.
Medical and health covers using the care this pays for, and essential living covers where enrolment fits in your first months.
