Overview
Moving to Korea requires navigating its comprehensive public healthcare system. For foreign residents, joining the National Health Insurance Service (NHIS) is generally mandatory. This guide covers enrollment requirements, monthly costs, coverage details, and when private insurance becomes relevant.
Disclaimer: This is general information, not legal, financial, or medical advice. Premium amounts and rules change yearly—confirm current figures with the National Health Insurance Service and your local immigration office via HiKorea.
Who Must Enroll, and When
Korea operates a single-payer public health insurance system. Foreigners have two main enrollment pathways:
Employee Subscribers (직장가입자)
If employed at a workplace covered by NHIS, a foreign worker is generally enrolled as an employee insured person. NHIS lists the 2026 employee contribution rate as 7.19% of monthly wage, normally shared 50:50 by employee and employer; a separate long-term-care premium may also apply. The official NHIS foreigner guidance describes a documented exclusion application for qualifying foreign insurance or employer-contract coverage, so do not present workplace enrollment as exception-free.
Local (Regional) Subscribers (지역가입자)
Students, freelancers, dependents, and other non-employed foreigners may be assessed as local subscribers under the applicable status and registration rules. NHIS's current guidance says a foreigner or overseas Korean who has stayed in Korea for over six months is subject to mandatory local subscription; the contribution is not a flat salary percentage and must be checked against the current NHIS assessment.
Dependents
Employee subscribers may register eligible family members as dependents without a separate premium when the NHIS relationship, income, property, and other recognition criteria are met. For foreign dependents, NHIS requires an Alien Registration Card or domestic residence report and authenticated family-relationship or marriage documents, with Korean translations where required. The current NHIS guidance does not support a universal list of visa-based immediate exceptions, so confirm the exact dependent decision with NHIS.
How Much You'll Pay Each Month
NHIS premiums are income and asset-based, not flat fees. The agency calculates "contribution payment according to the level of household's income and property."
Illustrative Monthly Premiums (2025–2026 estimates)
| Situation | Rough Monthly Premium (KRW) | Notes |
|---|---|---|
| Salaried worker, ~3,000,000 KRW/month | ~110,000 (worker's half) | Employer pays the other half |
| Salaried worker, ~5,000,000 KRW/month | ~180,000 (worker's half) | Deducted at payroll |
| Local subscriber, modest income/assets | ~150,000–250,000 | Income + property assessed |
| Foreign local subscriber (minimum floor) | Set minimum applies | Foreigners often pay a minimum even with low declared income |
The salaried-worker figures show your personal half only. NHIS lists a 7.19% employee-insurance contribution rate for 2026, normally split 50:50 between employee and employer before any separate long-term-care premium. Verify the actual payslip and NHIS bill.
Key point: Many foreign local subscribers face a minimum threshold premium despite low reported Korean income, preventing people from declaring minimal earnings to avoid contributions. International students may qualify for reduced (e.g., 50%) rates during studies—confirm with your campus international office.
What NHIS Actually Covers
The public scheme is broad, typically including:
- Outpatient doctor visits and most specialist consultations
- Hospitalization and surgery
- Prescription medications (with co-payment)
- Maternity and childbirth care
- Dental and traditional Korean medicine (partial coverage)
- Many diagnostic tests and imaging
You pay a co-payment at service—commonly around 30% for outpatient visits and less for hospitalization, with NHIS covering the remainder. Negotiated national base rates keep routine clinic visits modest out-of-pocket.
Usually NOT Fully Covered
Purely cosmetic procedures, advanced dental work (implants beyond certain rules), premium private hospital rooms, some new or expensive drugs, vision correction surgery, and elective treatments are "non-benefit" (비급여) items where bills escalate and private insurance becomes relevant.
Private Insurance: Do You Still Need It?
For most residents, NHIS is the foundation and private insurance supplements it. Common options include:
Korean Supplementary "Actual-Cost" Insurance (실손보험)
Reimburses out-of-pocket and non-benefit costs NHIS doesn't cover. Useful for long-term residents, though enrollment may be harder with pre-existing conditions and age limits apply.
International/Expat Health Plans
Portable across countries, often with English support and direct billing at international clinics. Premiums typically exceed NHIS costs substantially.
Travel Medical Insurance
Suitable only for short stays before NHIS becomes mandatory.
Strategy for newcomers: Use NHIS as core coverage, then add modest supplementary insurance if you anticipate dental work, want private rooms, or have chronic conditions.
Step-by-Step: Getting Set Up
- Get your Alien Registration Card (ARC) after arrival—required for most processes.
- If employed, confirm your employer enrolled you and check your first payslip for deductions.
- If a local subscriber, expect an NHIS enrollment notice and bill around the six-month mark; you can also visit an NHIS branch to register earlier.
- Set up automatic bank transfer (자동이체) for premiums to avoid missed payments—unpaid premiums can affect visa extensions.
- Register dependents with required civil-status documents if applicable, keeping in mind the six-month residence rule and its exceptions.
- Keep your address updated with NHIS and immigration so bills and notices reach you.
Common Mistakes to Avoid
- Assuming you can skip enrollment because "I have insurance back home"—after six months it's mandatory.
- Ignoring NHIS bills: arrears can complicate residence permit renewal via HiKorea.
- Forgetting that non-benefit items (cosmetic, premium rooms) aren't covered.
- Letting auto-pay lapse after changing banks.
FAQ
Is NHIS really mandatory for foreigners? Foreign employees at covered workplaces are generally enrolled through the workplace, while the current NHIS foreigner guidance generally subjects local subscribers after more than six months of stay. Documented exclusion or status-specific rules can apply, so check NHIS for the individual case.
How much of the premium do I actually pay as an employee? NHIS lists a 7.19% employee-insurance contribution rate for 2026, normally split 50:50, so the employee's share is generally half of the wage-based contribution before any separate long-term-care premium. Your payslip and NHIS bill control the actual amount.
Can I use only private insurance instead? Private insurance does not automatically replace NHIS. Most eligible residents must follow NHIS enrollment rules, although the official foreigner guidance describes limited documented exclusion cases for qualifying foreign insurance or employer-contract coverage.
Why is my premium so high with low income? Local subscribers, including many foreigners, are assessed on income and assets, and a minimum floor often applies.
Where do I confirm exact figures? Always check the current rate and your specific bill with NHIS directly, since rates are revised annually.

Quick decision checklist before you rely on NHIS alone
For most long-stay foreigners, NHIS is the foundation rather than the whole plan. Before you cancel private travel or expat insurance, check four practical points: whether your visa type triggers automatic enrollment, whether your employer reports your status correctly, whether your dependents are actually registered, and whether you need evacuation or international coverage that NHIS does not provide.
The common mistake is comparing only the monthly premium. A cheaper setup can become expensive if it leaves a waiting period, excludes a family member, or does not cover treatment outside Korea. If you are arriving for a short contract, study exchange, pregnancy, chronic treatment, or frequent travel, keep a written comparison of NHIS coverage, private policy exclusions, deductibles, and the phone number you would call in an emergency. That one page is more useful than a generic "best insurance" list.
