Health Insurance for Foreigners in Korea: NHIS Costs & Coverage
By WCS
Published: June 13, 2026 By: Damin Yun
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 by a Korean company, your employer enrolls you automatically. The total health insurance contribution is set as a percentage of your salary—7.09% in 2025 (rising to 7.19% in 2026)—and it is shared 50:50 between you and your employer. That means your personal share is roughly 3.5% of salary (about 3.545% in 2025), deducted directly from your pay, while your employer contributes the matching half. This is typically the most affordable option for workers. A separate Long-Term Care Insurance premium (a percentage of your health premium) is added on top and is also split 50:50.
Local (Regional) Subscribers (지역가입자)
Students, freelancers, dependents, and non-employed foreigners fall into this category. After six consecutive months of valid residence status in Korea, mandatory NHIS enrollment activates and you receive a bill—opting out is not permitted.
Dependents
Employee subscribers can register qualifying family members (spouses, lineal relatives) as dependents without extra premiums, provided they have no other significant income and live at the same address. Note that since April 2024, foreign nationals generally must have resided in Korea for at least six months before they can be registered as dependents. Important exceptions apply—spouses, children under 19, and certain visa categories (such as D-2, D-4-3, E-9, and F-6) and permanent residents can qualify immediately, and a foreign spouse of an already-enrolled subscriber may also be added right away. Foreign dependents require stricter documentation, including apostilled family relationship certificates.
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. The 2025 total health insurance rate is 7.09% of income, split 50:50 with your employer, so an employee effectively pays about 3.5% of salary. Figures are rounded.
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? Yes, generally after six months of continuous stay for local subscribers, and immediately for company employees.
How much of the premium do I actually pay as an employee? The 2025 total rate is 7.09% of salary, split 50:50, so your personal deduction is about 3.5% (roughly 3.545%); your employer pays the matching half. The total rate rises to 7.19% in 2026.
Can I use only private insurance instead? No—NHIS enrollment is required by law for most residents; private plans supplement it.
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.
