Quick Answer
Foreign students on D-2 or D-4 visas are automatically enrolled in NHIS after 6 continuous months in Korea. The 2026 monthly premium is β©79,320. You pay around 30β50% of medical costs at the clinic; NHIS covers the rest. Unpaid premiums can block your visa renewal.
What Is NHIS?
NHIS (National Health Insurance Service / κ΅λ―Όκ±΄κ°λ³΄ν곡λ¨) is Korea's mandatory public health insurance system. It covers the majority of medical costs at hospitals, clinics, and pharmacies β meaning you only pay a fraction of the actual bill.
Before NHIS was extended to foreigners, international students often faced full uninsured costs for even minor health issues. Now, most long-term foreign residents are included in the system, making basic healthcare genuinely affordable.
Who Gets Enrolled β and When?
Enrollment rules differ depending on your visa type and length of stay:
- D-2 (university student) and D-4 (language institute) visa holders are automatically enrolled after 6 continuous months in Korea
- Some universities enroll students earlier through a university group insurance scheme β check with your international office in the first week
- F-visa holders (F-2, F-4, F-6) are generally enrolled from the moment they register as residents
- If you are on a short-term visa or have been in Korea less than 6 months, you are not yet covered by NHIS
How Much Does It Cost in 2026?
The standard monthly NHIS premium for foreign local subscribers (μ§μκ°μ μ) in 2026 is β©79,320. This amount is fixed regardless of your income or how often you visit the doctor β it is a flat monthly fee.
On top of the monthly premium, you pay a copay at each visit. For a standard clinic visit, this is usually β©5,000β20,000 after NHIS covers its share. Hospital stays, surgery, and specialist visits have higher copays but are still significantly cheaper than uninsured rates.
What Does NHIS Cover?
NHIS covers a broad range of medical services. Here is what international students commonly use it for:
- GP and clinic visits (μμ) β 30β50% copay, typically β©5,000β20,000 per visit
- Prescriptions β you pay around 30% of the drug cost at the pharmacy
- Hospital stays and surgery β covered, with higher copays depending on the ward type
- Dental β basic dental care is partially covered (fillings, extractions, scaling once per year)
- Mental health consultations at clinics β covered at the same copay rate as regular visits
- Emergency room visits β covered, though ER copays are higher than regular clinics
Before 6 Months: What Are Your Options?
During the first 6 months in Korea, you are not yet covered by NHIS. This is the gap period where most international students are most vulnerable to unexpected medical costs.
Your options during this period: (1) University insurance β many Korean universities provide basic group health insurance for enrolled students; check your student portal or international office on arrival. (2) Private travel/expat insurance such as SafetyWing (~$45/month), which covers medical emergencies worldwide with no long-term commitment and works well as a bridge until NHIS kicks in.
How to Check Your Enrollment Status
Once you have been in Korea for 6 months, you should verify that you have been enrolled. Here is how:
- Visit nhis.or.kr β log in with your ARC number to check your enrollment status and monthly premium
- Call 1577-1000 β NHIS customer service is available with multilingual support (Korean, English, Chinese, and more)
- Visit your nearest district office (ꡬμ²/μ£Όλ―ΌμΌν°) β they can confirm your status and help you register if needed
- Once enrolled, you will receive a health insurance card in the mail β keep it with your ARC
What Happens If You Don't Pay?
Missing NHIS payments has real consequences. After a few months of unpaid premiums, your NHIS coverage is suspended β meaning you lose the copay benefit and pay full uninsured rates at clinics.
More importantly: unpaid NHIS premiums are checked during visa renewal. If you have outstanding balances, your visa renewal can be delayed or denied. Pay on time every month β you can set up auto-payment at nhis.or.kr or your Korean bank's app.
Practical Tips for International Students
- Check with your international office in the first week β some universities start insurance coverage from day one of enrollment
- Set up auto-payment for NHIS premiums through your Korean bank account so you never miss a payment
- Keep your NHIS health insurance card with your ARC β you need to present it at every clinic visit
- If you visit a clinic without your card, you pay the full uninsured rate upfront (you can claim a refund later but it's a hassle)
- For dental cleanings (μ€μΌμΌλ§), NHIS covers one session per year β use it
- If you go to a large university hospital (λνλ³μ) instead of a local clinic for a minor issue, your copay is significantly higher
