Most insurance guides start with the system and work toward your situation.
This one works the other way. These are the questions foreigners in Korea actually ask — the ones that come up in expat forums, Facebook groups, and conversations with people who’ve been here long enough to have had something go wrong.
The answers are direct. The goal is to save you the time of reading four different articles to find what you actually need to know.
“I just arrived in Korea. Do I have health insurance yet?”
Depends on your visa and employment situation.
If you started employment at a Korean company, your employer is legally required to enroll you in NHIS from your first day of work. Check your first paycheck — NHIS deductions should appear there. If they don’t, follow up with HR.
If you’re on a long-term visa but not employed (student, dependent, self-employed), you need to enroll yourself as a local subscriber. This happens when you register your ARC at the local immigration office or district office — enrollment is initiated at that point.
If you just arrived and haven’t sorted any of this yet, you technically have a coverage gap. A short-term travel insurance policy fills that window.
“My employer handles my NHIS. Do I actually need to do anything?”
One thing: verify it happened. Log into nhis.or.kr and check your membership status. Employer enrollment should show as active from your start date. If it doesn’t, contact your employer’s HR before you need to use healthcare.
Errors in enrollment processing are not common but they happen. Finding out after you’ve been to the hospital that your coverage wasn’t actually active is a much worse situation than spending five minutes checking upfront.
“I went to the doctor and paid ₩8,000. Is that normal?”
Yes. NHIS covers 70–80% of treatment costs at local clinics. A standard outpatient visit where you pay ₩6,000–₩15,000 out of pocket is working as intended.
The costs increase significantly at higher-tier facilities. If you go directly to a large university hospital instead of a local clinic for something that doesn’t require specialist care, your copayment will be substantially higher. Korea’s healthcare system is designed to funnel routine care through local clinics — using them is both cheaper and usually faster.
“What does NHIS actually not cover? I keep getting surprised.”
The main gaps that surprise people most often are these.
Dental implants are not covered for people under 65. Neither is orthodontics, most cosmetic dental procedures, or teeth whitening. A single implant costs ₩1,000,000–₩1,500,000 out of pocket.
Mental health treatment is covered but at lower reimbursement rates than physical health. Frequent therapy sessions add up meaningfully even with coverage.
Treatments that don’t meet the “medically necessary” definition under NHIS guidelines may be partially or fully out of pocket even when a doctor has ordered them. This includes some diagnostic imaging ordered as a precaution.
For a detailed breakdown of NHIS coverage, see our Korean national health insurance guide.
“What is silsoniboheom and do I need it?”
Silsoniboheom (실손보험) is private supplementary insurance that reimburses the copayment you pay after NHIS covers its portion. If your clinic visit costs ₩8,000 out of pocket, silsoniboheom reimburses most of that.
Important clarification that many people get wrong: silsoniboheom does not cover treatments that NHIS doesn’t cover. It covers your share of treatments that NHIS does cover. Dental implants are still not covered, even if you have silsoniboheom.
Whether you need it depends on how often you use healthcare. For families with children, people managing ongoing health conditions, or anyone who wants financial protection against unexpected illness, it’s generally worth it. For young, healthy individuals who rarely see a doctor, the monthly premium may exceed the actual benefit. For the full comparison, our health vs private insurance guide works through the decision in detail.
“I filed a claim and they paid less than I expected. What happened?”
Several possible reasons.
The most common is the 20–30% copayment structure — NHIS covers its portion, you pay the rest, silsoniboheom reimburses most of your portion but not all of it. The math sometimes produces a smaller reimbursement than people expect.
Another common reason is that the specific treatment or procedure falls partly outside NHIS coverage. The medical necessity standard is applied strictly, and treatments that a doctor ordered but that don’t meet that standard may receive lower coverage.
If you believe the calculation is wrong rather than just lower than expected, request a written breakdown of how the payout was calculated. If the denial or reduction appears inconsistent with your policy terms, you can escalate through the insurer’s internal appeals process or file a complaint with the Financial Supervisory Service at fss.or.kr.
“My car got hit by someone with no insurance. What do I do?”
If you have uninsured motorist coverage (무보험차상해) on your own policy, file a claim with your own insurer. They cover your costs and handle the other party.
If you don’t have that coverage, your options are more limited. Your mandatory liability insurance covers damage and injury to others — not to yourself. For your own vehicle repairs and medical costs, you’d need to pursue the other driver directly, which can involve legal proceedings.
This situation is exactly why uninsured motorist coverage is worth adding. For more on what comprehensive car coverage actually includes, see our car insurance guide.
“I’m leaving Korea next month. What do I need to do about insurance?”
NHIS coverage ends when you deregister your ARC or leave the country. If you’ve overpaid premiums, you can apply for a refund through NHIS before departure.
For private insurance — silsoniboheom, life insurance, car insurance — contact each insurer directly to cancel. Most require advance notice. Check for any refund of prepaid premiums and any outstanding claims you should submit before canceling.
Car insurance should remain active until the day you stop driving. Don’t cancel it early.
“Is there English support for insurance in Korea?”
For NHIS: the nhis.or.kr website has an English section, and there is a foreign-language support line available.
For private insurers: English support varies. Samsung Fire and Hyundai Marine have the most accessible English lines among major insurers. For complex situations — large claims, policy disputes, choosing between products — an expat-focused insurance broker with English service is the most reliable option.
For general insurance questions in Korea, the Financial Supervisory Service’s consumer portal at fss.or.kr has English-language resources.
If your question isn’t covered here, the most direct routes are nhis.or.kr for NHIS-related queries, fss.or.kr for regulatory and complaint matters, and your insurer’s direct line for policy-specific questions.
