Health insurance for hagwon teachers: what you pay and what it covers
Your hagwon pays half your National Health Insurance premium. Here's how co-payments work at clinics and hospitals, what isn't covered, and when a private top-up policy is worth it.

The E-2 contract says the school pays half your health insurance, and it does. What's worth knowing before your first clinic visit is how co-payments work.
We've watched this happen more times than we can count. A teacher gets sick in week three, walks into a clinic near the hagwon, hands over the ARC, gets seen, gets meds, and pays something at the counter that feels arbitrary. It isn't arbitrary. It's a co-payment, and Korea's National Health Insurance runs almost entirely on them.
How the co-pay actually works
NHIS is real insurance, run by one government body, and it does pay most of the bill. But it isn't free-at-the-door care the way some teachers expect coming from the UK or Canada. The standard co-payment rate on insured services for inpatient care is 20 percent and between 30 and 60 percent for outpatient care, depending on the level of provider. Clinics (the small neighborhood places most teachers actually use) sit at the low end of that range; bigger hospitals and tertiary centers sit at the high end.
So a cold treated at a local clinic tends to be cheap. Anything that sends you up to a general or university hospital gets noticeably more expensive, fast, because the co-pay percentage climbs with the size of the institution, not just the treatment.
Things NHIS doesn't touch at all:
- Most cosmetic dental work and orthodontics
- Glasses, contacts, and the eye exam itself
- A handful of drugs the formulary treats as elective
What comes out of your paycheck
The contribution rate is set annually by the Ministry of Health and Welfare and split exactly in half between you and the school. The rate was 7.09% in 2025 and rose to 7.19% for 2026. Long-term care insurance rides along on top of that automatically. You don't opt into it, it's just added to the health premium.
Using the current rate, here's roughly what comes off a monthly salary before the school matches it:
| Monthly salary | Your half (health only) | School's half | Total to NHIS |
|---|---|---|---|
| ₩2,000,000 | ~₩71,900 | ~₩71,900 | ~₩143,800 |
| ₩2,200,000 | ~₩79,100 | ~₩79,100 | ~₩158,200 |
| ₩2,400,000 | ~₩86,300 | ~₩86,300 | ~₩172,600 |
| ₩2,500,000 | ~₩89,900 | ~₩89,900 | ~₩179,800 |
These are health-insurance-only figures at the rate in effect this year; long-term care adds a smaller amount on top, and the total rate does move most years. Check your own payslip against the current rate on nhis.or.kr; it's the only place we'd trust over our own table.
What teachers actually do about the gap
Plenty of teachers buy a private supplement at some point in their contract, usually after the first clinic bill surprises them. These policies are sold by Korean insurers (DB Insurance and Samsung Fire & Marine both offer English-language options) and typically close some of what NHIS leaves open: dental up to a cap, glasses, hospital admission co-pays. We can't give you a reliable premium range here, because the honest answer is that it varies by age, insurer, and what you want covered. Get a quote directly from the insurer rather than trusting a number in an article.
Some teachers skip it entirely and self-insure. That's a fine bet if you're young, healthy, and see a doctor twice a year. It's a worse bet if you wear glasses or have any ongoing prescription.
The part nobody asks about until it matters
If you leave a job or the hagwon closes, coverage runs until the end of the last month it was paid for, then stops. If you're between E-2 sponsors, the gap is usually short enough to just pay out of pocket for a couple of weeks, or pay one month yourself to keep it active. The form for that is on the NHIS English site. F-visa holders freelancing are required to register and pay both halves themselves, and it's not a small bill.
Worth the private supplement?
Probably yes if you wear glasses, have any regular prescription, or have ever needed dental work beyond a cleaning. Probably skip it if you're young, healthy, and haven't seen a dentist since you got here. Either way, it's cheaper than one uninsured root canal.
