In short
- Korea's National Health Insurance (NHIS) is mandatory for foreigners staying 6+ months. It's not optional — and it's genuinely excellent value.
- Employed? Your employer enrolls you from day one and splits the premium 50/50 (your share is about 3.5–4% of salary).
- Not employed? You become a "local subscriber" after 6 months, paying a flat-ish premium (roughly ₩80,000–₩160,000/month). D-2/D-4 students get a ~50% discount.
- NHIS covers 60–80% of most medical costs — a clinic visit often ends up around ₩5,000–₩10,000. Unpaid premiums can block your visa extension.
Korea's healthcare is one of the best-value systems you'll ever use: walk into a clinic, see a doctor within about 20 minutes, get a prescription next door, and pay under ₩15,000 total. NHIS is what makes that possible — and enrollment is a legal requirement, tied directly to your right to stay.
Who has to enroll, and when
- Employed foreigners: your employer must enroll you as a "workplace subscriber" (직장가입자) from your first day, regardless of how long you've been in Korea.
- Everyone else (students, freelancers, unemployed, dependents): mandatory enrollment as a "local subscriber" (지역가입자) once you've been in Korea 6 months.
- Faster enrollment: certain visas (D-2, E-9, F-5, F-6, and others) are typically enrolled from the moment you get your ARC, skipping the 6-month wait.
What it costs
For employees, the total health-insurance rate in 2026 is about 7.09–7.19% of gross salary, split evenly with your employer — so your share is roughly 3.5–4% (including the small Long-Term Care add-on). On a ₩3,000,000 salary that's around ₩120,000/month from your pay.
For local subscribers (not employed), foreigners pay a flat-rate premium based on the previous year's average rather than the complex Korean scoring system — commonly in the ₩80,000–₩160,000/month range. D-2 and D-4 students get about a 50% discount, bringing it down to roughly ₩76,000–₩80,000/month.
What it covers (and doesn't)
NHIS covers 60–80% of most outpatient visits, hospital stays, prescriptions and major surgery — you pay the rest as a co-pay. A neighborhood clinic (의원) visit typically costs you ₩5,000–₩10,000, plus a few thousand won for medication. There's also a cap on annual out-of-pocket costs for serious illness (cancer, major surgery), so a big hospital bill won't bankrupt you. NHIS works at virtually every hospital and pharmacy — no network restrictions.
Not well covered: most dental, vision, elective MRIs, and much of talk therapy/counseling — people often use supplemental private insurance for these gaps.
The first-6-months gap
If you're not employed, you have no NHIS coverage for your first 6 months — you'd pay 100% out of pocket for any care. Bridge it with a short-term international plan (roughly $50–$150/month from providers like Cigna, AXA, Pacific Prime), or check whether your home-country travel insurance covers the start of a long stay.
How to enroll and pay
Employed → nothing to do
Your employer registers you. Confirm with HR within your first month, and check your payslip shows the right deduction.
Not employed → NHIS usually auto-enrolls you
NHIS monitors your ARC and residency and mails a bill to your registered address after 6 months. To enroll or check manually, visit an NHIS branch with your ARC and passport, or call the helpline.
Set up auto-debit (자동이체)
Link your Korean bank account for automatic payment. This is the single most important step — a missed payment blocks your coverage and, if debts build up, your visa renewal.
Add dependents if eligible
You can add a spouse/children as dependents (피부양자) — often at no extra premium — with apostilled, translated proof of relationship, if they meet residency and income/asset limits.
Common questions
Can I opt out if I have foreign insurance?
No. NHIS is mandatory for eligible residents regardless of any private or home-country insurance. Those can act as supplements, not replacements.
What if I don't pay?
Missed payments block your coverage (you pay 100% at clinics), and unpaid premiums above a threshold flag your immigration record — the officer will see it and can deny your visa extension. Always auto-pay.
What if I leave Korea for a while?
Leaving for more than 30 consecutive days may suspend coverage/premiums depending on your visa — notify NHIS. Short trips don't interrupt the 6-month count for new enrollees.
Is there English support?
Yes — call the NHIS multilingual line (1577-1000, or 033-811-2000 for foreign languages). The NHIS website and app also have an English interface.
