One of the most common questions foreigners in Korea ask about insurance is whether the national health coverage they’re already paying for is actually enough — or whether they need to add private insurance on top of it.
The short answer is: it depends on your situation. But there are some pretty clear patterns in who benefits from adding private coverage and who doesn’t really need it.
What You’re Already Covered For
If you’ve been in Korea for more than six months on a qualifying visa, you’re almost certainly already enrolled in the National Health Insurance Service (NHIS). That means you’re already covered for a significant portion of most medical expenses.
| Medical Service | NHIS Coverage |
|---|---|
| Clinic visits | 70–80% |
| Hospitalization | 80% |
| Surgery | 80% |
| Prescriptions | 70–80% |
| Basic dental | Partial |
| Mental health | Partial |
| Cosmetic / elective | Not covered |
The part you pay yourself — called the copayment — adds up to 20–30% of the total cost. For routine visits this is usually manageable. A standard clinic appointment typically costs somewhere between ₩3,000 and ₩15,000 out of pocket after NHIS covers its portion.
Where things get more expensive is with extended hospital stays, major surgeries, or chronic condition management. That’s where private supplementary insurance starts to make more sense.
What Is Silsoniboheom (실손보험)?
The most common type of private insurance foreigners add in Korea is called 실손보험, or actual loss insurance. Unlike life insurance or specific disease coverage, silsoniboheom reimburses you for the out-of-pocket portion you paid after NHIS kicked in.
In practical terms, it works like this. You visit the hospital, NHIS covers 80%, you pay 20%. Then you submit the receipt to your silsoniboheom insurer, and they reimburse most of that 20%.
| Feature | Details |
|---|---|
| What it covers | Your copayment after NHIS |
| Monthly cost (2026 avg.) | ₩30,000 ~ ₩80,000 depending on age and plan |
| Reimbursement rate | 80–90% of your copayment |
| Who can apply | Foreigners with ARC and NHIS enrollment |
| Age limit | Most plans available up to age 65 |
It’s worth noting that silsoniboheom premiums have increased significantly over the past few years, and the 2026 plans have higher deductibles than older policies. If you already have an older plan, keep it — the terms are usually better than what’s available now.
Should You Get Private Insurance?
There’s no one-size-fits-all answer, but here’s a realistic way to think about it.
You probably don’t need private insurance if you’re young and generally healthy, rarely visit the hospital, are only staying in Korea for a year or two, and your main concern is routine medical care. In that case NHIS alone is likely enough, and the monthly private insurance premium might not be worth it.
Private insurance makes more sense if you have a pre-existing condition that requires ongoing treatment, you have a family with children who need regular medical attention, you want coverage for dental work beyond basic treatment, or you’re planning to stay in Korea long-term and want financial protection against unexpected serious illness.
What NHIS Doesn’t Cover Well
There are a few areas where the national insurance falls noticeably short, and these are worth knowing about before you assume you’re fully covered.
Dental care is a big one. NHIS covers basic extractions and fillings at standard rates, but implants, orthodontics, and most cosmetic dental work are not covered at all. A single dental implant in Korea can cost ₩1,000,000 ~ ₩1,500,000 entirely out of pocket.
Mental health services are covered in theory, but the reimbursement rates are lower than for physical health, and many people find that frequent sessions still add up quickly without supplementary coverage.
MRI and CT scans are covered when medically necessary, but medically necessary is defined fairly narrowly. If a doctor orders a scan as a precaution rather than in response to a clear diagnosis, you may end up paying significantly more.
Practical Steps If You Want to Add Private Coverage
Step 1. Confirm your NHIS enrollment status first. Private insurers will require proof of enrollment, and your coverage under silsoniboheom is built on top of NHIS — not separate from it.
Step 2. Compare plans through a Korean insurance broker who works with foreigners, or use the official comparison portal. Bring someone who speaks Korean if needed — the fine print matters.
Step 3. Be honest on the application about any pre-existing conditions. Undisclosed conditions can result in claim denials later, which defeats the entire purpose.
Step 4. Keep your receipts. Silsoniboheom claims require itemized hospital receipts. Most hospitals and clinics will provide these automatically, but it’s worth double-checking before you leave.
Q&A
Q. Can foreigners actually get private insurance in Korea?
A. Yes, most major Korean insurers offer plans to foreign residents with a valid ARC and NHIS enrollment. English support varies, but the coverage itself is the same as for Korean nationals.
Q. Is travel insurance enough instead of getting local private insurance?
A. Travel insurance is designed for short trips, not long-term residency. Most travel policies cap coverage at 90 days and exclude pre-existing conditions. If you’re living here, local coverage is the better option.
Q. What happens to my private insurance if I leave Korea?
A. Most plans terminate when you cancel your NHIS enrollment or lose your ARC. Some insurers allow a short grace period. Check the cancellation terms before you sign up.
Q. How do I actually make a claim?
A. Keep all hospital and pharmacy receipts. Submit them to your insurer through their app or by visiting a branch. Most insurers process claims within 3–5 business days.
For most foreigners in Korea, NHIS provides solid baseline coverage that handles day-to-day medical expenses reasonably well. Whether you add private insurance on top really comes down to how long you’re staying, your health situation, and how much financial exposure you’re comfortable with.
