National Health Insurance (NHIS) for Foreigners in Korea: Who Must Join and How (2026)
Short answer: If you live and work at a business that is covered by workplace insurance, your employer enrols you in Korea’s National Health Insurance (NHIS) automatically. If you are not an employee, you must join as a “regional” (self-employed) subscriber once you have stayed in Korea for more than six months. That rule has applied since July 16, 2019. A few visa types start earlier, and a few are excluded.
This guide explains the two subscriber types, the visa-based exceptions, dependents and what the insurance does not pay for. It is based on NHIS’s own English and Korean pages. Some of those pages are older than others, so where the date matters it is stated below.
The two ways to be enrolled
| Employee subscriber | Regional (self-employed) subscriber | |
|---|---|---|
| Who | People who work at an insured workplace, including public officials and private school staff | Residents who are not employees or dependents, such as the self-employed, students and people not working |
| How you join | Automatically, through your employer’s report | Compulsory after more than 6 months in Korea (earlier for some visas) |
| Who pays | Employee and employer each pay 50% | You (or your household) pay the whole bill |
| How the premium is set | Monthly wage times a rate | Points for income, property and cars |
NHIS’s English guidance for foreigners states that foreigners and overseas Koreans who live and work at an insured workplace are enrolled as employee subscribers, and that those who have stayed more than six months must enrol as regional subscribers.
The 6-month rule and the visa exceptions
NHIS says the six-month mandatory enrolment has applied since July 16, 2019. Its Korean policy page then lists how it works by visa status:
- E-9, F-5 and F-6 holders are enrolled from their date of entry. If your foreigner registration came after entry, coverage runs from the registration date.
- D-2 (study) and D-4 (general training) students have been subject to compulsory enrolment since March 1, 2021.
- Excluded statuses: A (diplomatic), B (tourism), C (short-term) and most G-1 holders. The exceptions are G-1-6 and G-1-12 (humanitarian stay), who can enrol.
So a tourist or short-term visitor is not part of NHIS. Travel insurance is a separate matter, and this guide does not cover it.
NHIS’s English page also lists eligible visa groups (D-1 to D-9, E-1 to E-10, F-1 to F-6, H-1, H-2) and overseas Koreans registered under Korean law. Because that list is older, use it as a guide rather than a final answer and ask NHIS about your exact status.
Exemptions: already covered somewhere else
Some foreigners can apply to be excluded if they can prove equivalent medical coverage, either through a foreign law or insurer, or through a contract with their employer.
- For employee subscribers, NHIS says a withdrawal application filed within 14 days of the enrolment report makes the coverage start date also the loss date. The “Employee Health Insurance Withdrawal Application” and supporting documents are needed.
- For regional subscribers, NHIS’s Korean page says the exemption covers one year at a time and must be applied for again after that. It also says only foreign coverage taken out before you arrived is recognised.
Exemption decisions are made by NHIS, so do not assume you qualify. Ask before the first bill arrives.
How to enrol
- Employees: Your employer files the report. You usually do not need to do anything except provide your details.
- Regional subscribers: NHIS’s English page does not give a step-by-step process. It says to contact the NHIS branch for your address for dependents and special cases. Branches can be reached through the call center at 1577-1000, and NHIS lists an English consultant line at 033-811-2000.
Bring your Alien Registration Card, passport and, for dependents, family documents (see below).
Dependents
An employee subscriber can cover certain family members as dependents, so they do not pay their own premium. NHIS’s Korean dependent page lists:
- Who: a spouse, parents and grandparents, children and grandchildren (and their spouses), and siblings in limited cases (under 30, 65 or older, or with a disability).
- Income: total annual income of KRW 20 million or less. If the dependent is married, both spouses must meet this.
- Property: a taxable property value of KRW 540 million or less. Between KRW 540 million and 900 million, annual income must be KRW 10 million or less.
- Foreigners and overseas Koreans who entered Korea on or after April 3, 2024: they must meet a residence requirement of at least 6 months in Korea, with listed statuses (D-2, D-4-3, E-9, F-5, F-6 and similar). The employee’s spouse and the spouse’s minor child are exempt from this.
The exact wording of how the 6-month and visa-status parts combine is not clear from the page, so confirm it with NHIS for your case.
For documents, NHIS’s English page says family or marriage records issued by your government need an Apostille or consular confirmation, must be dated within 9 months, and need a Korean translation if they are not in Korean. A dependent who fails the tests may be moved to regional status and pay their own premium.
What NHIS covers and what it does not
Foreign subscribers get the same benefits as Korean citizens, according to NHIS. Covered care includes diagnosis, tests, treatment, surgery, hospital stays, rehabilitation, childbirth support and certain health checkups.
You still pay a share (co-payment). NHIS’s English benefits page lists, as examples:
| Care | Patient share |
|---|---|
| Inpatient care | 20% of the total cost |
| Outpatient, clinic | 30% |
| Outpatient, hospital | 40% |
| Outpatient, general hospital | 45% or 50% depending on the area |
| Outpatient, tertiary hospital | 60% |
| Pharmacy | 30% |
An annual cap on out-of-pocket costs applies, set by income level. NHIS repays amounts above the cap, but not for items it excludes from the ceiling, such as non-covered services, dental implants, higher-grade hospital rooms (2 to 3 beds), and childbirth expenses.
NHIS’s page does not give a complete list of treatments that are not covered. Cosmetic and elective procedures are commonly paid out of pocket, but check with the clinic or NHIS before you assume anything about a specific treatment.
What happens if you do not pay
NHIS’s Korean page says unpaid premiums can lead to limits on benefits from the day after the due date, and it warns of effects on immigration matters such as extending your stay. That page is dated, so confirm the current consequences with NHIS and your immigration office.
Quick checklist
- Do I work at an insured workplace? Then confirm my employer has reported me.
- Have I stayed in Korea for more than six months, and is my visa group one that must enrol?
- Do I have foreign coverage that I can document for an exemption?
- Is a family member eligible as a dependent, and do I have apostilled documents?
- Do I have my ARC, passport and the contact for my local NHIS branch?
Common mistakes
- Assuming a tourist or short-term status counts toward the six months.
- Ignoring the first bill after the six-month point and letting it pile up.
- Applying for dependent status without the apostilled, translated family documents.
- Treating co-payments as “free care” and not budgeting for the patient share.
