Korea&YouKorean National Health Insurance: Enrollment, Cost, and What's Covered
Why you're already enrolled whether you applied or not, and what it actually costs in 2026
Korean National Health Insurance (NHIS) is compulsory for foreign residents, and unlike almost everything else in this series, there's no application to fill out. You become a subscriber automatically once you meet the conditions — and for most exchange students, that happens shortly after arrival.
Quick answer: If you're on a D-2 student visa, your NHIS coverage starts from your date of entry (or your alien registration date, if this is your first time entering Korea) — there's no waiting period. The 2026 premium for D-2 students is ₩79,320 a month, half the average subscriber premium, and it gives you the same benefits as Korean citizens with no separate claims process.
When Enrollment Begins
• Student visa (D-2), including exchange students: from your date of entry, or your alien registration date on first entry.
• School pupil (D-4-3): same as above.
• General trainee (D-4): six months after your date of entry.
The length of your stay isn't the test — even a single-semester exchange student is enrolled shortly after arrival. Insurance required by your home university, or a private travel policy, does not exempt you from this by default; a formal exclusion process exists but is genuinely difficult to qualify for (more on that in the next post).
What It Costs
D-2 students receive a 50% reduction on the standard premium. For 2026, that works out to:
• Monthly premium: ₩79,320
• One semester (4 months): about ₩317,000
• One semester (5 months): about ₩397,000
• Two semesters (10 months): about ₩793,000
The 50% reduction requires both your monthly income to be ₩300,000 or less and your assessed property value to be ₩135 million or less — this rarely affects exchange students, but keep it in mind if you take on part-time work.
What You're Actually Covered For
Your benefits are identical to a Korean citizen's. NHIS covers roughly 40–70% of outpatient treatment, 80% of hospitalization, and 90–95% of care for cancer, cardiac, cerebrovascular, and other severe conditions. There's no claims process to file — you simply show your Residence Card at reception, are treated at the insured rate, and pay the remaining copay directly.
• Register at reception, showing your Residence Card.
• See the doctor and receive a prescription.
• Pay the consultation copay on the spot.
• Take the prescription to a pharmacy and pay for the medicine.
How to Pay
Premiums are billed in advance, and the deadline is the 25th of the preceding month — April's premium, for instance, is due by March 25th. Assuming payment falls at the end of the month it covers is the single easiest way to fall into arrears in your first month.
• Automatic debit from a bank account or card, collected on the 25th of the preceding month.
• Virtual account transfer — send the amount to the account number on your bill, or call NHIS for the number if you have no bill.
• Bank CD machines and ATMs, NHIS branches, or convenience stores.
• The NHIS mobile app — check your balance and pay in one place.
Card payments carry a small surcharge (0.8% for credit, 0.5% for debit) — direct debit from a bank account is free, and switching to automatic debit plus electronic billing takes an extra ₩400 off your monthly premium.
The Bottom Line
There's nothing to apply for and nothing to opt out of — just budget roughly ₩79,000 a month and set a reminder for the 25th. What happens if you miss that deadline, travel home for a while, or move apartments is covered in the next post.
