This guide explains Korea health insurance for foreigners, including enrollment, premiums, coverage, dependent rules, and English-language support.
For many newcomers, the first sign of Korean health insurance is either a deduction on a payslip or an NHIS bill arriving in the mail. The difficult part is usually not using the insurance at a clinic. It is working out why you were enrolled, whether the amount is correct, and what to do when your job, visa, school, or family situation changes.
The Korean National Health Insurance Service (NHIS) covers most residents, including many foreign nationals. Your enrollment date, monthly premium, and application process, however, depend on your employment, residence status, income, and family situation. Below is the practical information you need to check your own case in 2026.
Quick answer: Foreign employees at an NHIS-covered workplace are generally enrolled through their employer. Many other registered foreign residents become self-employed subscribers after staying in Korea for more than six months. Exceptions and different enrollment dates can apply, so confirm your individual status with NHIS.
What Is Korean National Health Insurance?
Korea operates a public health insurance system managed by the National Health Insurance Service. Once you are enrolled, you receive the same categories of NHIS benefits available to Korean subscribers, including covered treatment, examinations, hospitalization, prescriptions, rehabilitation, and eligible health screenings.
NHIS does not make all medical care free. At a clinic, hospital, or pharmacy, you normally pay a portion of the covered cost, called a co-payment. The percentage varies depending on the type of medical institution, the service, and whether the treatment is covered by NHIS.
Private insurance can provide additional protection, but it does not automatically replace mandatory NHIS enrollment.
Korea health insurance for foreigners: who must enroll?
Foreign residents generally fall into one of three groups.
1. Employee-insured subscribers
If you work for a company that participates in NHIS, your employer normally registers you as an employee-insured subscriber. This applies to many employees holding E-series work visas as well as other eligible residence statuses.
Enrollment is usually connected to the start of covered employment rather than the six-month rule. Your part of the premium is deducted from your salary, and the employer pays the other half of the health insurance contribution.
Check your first payslip and ask your employer’s human-resources or payroll team if you are unsure whether registration has been completed.
2. Self-employed or regional subscribers
Many registered foreigners and overseas Koreans who are not insured through an employer become self-employed subscribers after staying in Korea for more than six months. This category includes many students, dependents, job seekers, freelancers, and residents who are not attached to an NHIS-covered workplace, provided their residence status is eligible.
The six-month calculation can be affected by departures from Korea, changes in immigration status, and the date your stay is considered to have started. Certain residence statuses can also follow different timing rules. Do not assume that every foreign visitor becomes eligible after six calendar months; short-term visitors are not treated the same as registered long-term residents.
3. Dependents of an employee-insured subscriber
A spouse, child, parent, or another qualifying relative may be registered as a dependent of an employee-insured subscriber if the family relationship and NHIS income, property, and dependency requirements are satisfied.
Being married to an insured employee does not make dependent registration automatic. NHIS may require official family documents, proof of income or property, and evidence that the relationship meets its rules.
How Much Does NHIS Cost in 2026?
Employee-insured premium
The employee health insurance contribution rate for 2026 is 7.19% of the monthly average wage. At an ordinary company, the employer and employee each pay 50% of that health insurance contribution.
For example, if NHIS calculates the premium using a monthly wage of KRW 3,000,000:
- Total health insurance contribution: approximately KRW 215,700
- Employee share: approximately KRW 107,850
- Employer share: approximately KRW 107,850
This simplified example excludes rounding and the separate long-term care insurance contribution that is collected together with health insurance. For 2026, the long-term care insurance rate is 13.14% of the health insurance contribution, equivalent to 0.9448% of wages in the standard calculation.
Your actual payroll deduction can differ because NHIS uses the wage amount reported for insurance purposes and applies its own calculation and rounding rules.
Self-employed foreign resident premium
Self-employed subscriber premiums are assessed using household income, property, and other information available to NHIS. For many foreign regional subscribers, if the calculated amount is lower than the nationwide average premium used for this rule, the average amount is charged instead.
For 2026, the published average premium for foreign regional subscribers is KRW 158,630 per month, including long-term care insurance.
That number often surprises people, but it is not a universal flat fee for every foreign resident. F-5 permanent residents, F-6 marriage immigrants, recognized refugees, minors, students receiving a reduction, and households with assessable income or property may be calculated differently. Treat KRW 158,630 as an important reference amount, not a guaranteed personal bill.
When is payment due?
NHIS states that monthly contributions are generally due by the 10th of the following month. Employee contributions are normally withheld through payroll. Regional subscribers receive a bill and can ask NHIS about automatic transfer or other payment methods.
If a bill does not arrive, do not assume that no payment is required. Confirm that your registered address is current and contact NHIS before unpaid premiums accumulate.
Health Insurance Reductions for International Students
Eligible students with D-2 or D-4 status, and certain F-4 or overseas-Korean students, may receive a 50% premium reduction under the current NHIS guidance. The reduction is not based on visa status alone.
NHIS also applies income, property, school, and household conditions. Its published guidance refers to an annual income threshold of KRW 3.6 million and a property-tax assessment threshold of KRW 135 million for relevant foreign-resident reductions.
Before relying on the discount, ask your university’s international office or NHIS to confirm:
- whether your school and residence status qualify;
- whether NHIS has received your enrollment information;
- whether the reduction appears on your bill; and
- what happens during a leave of absence, graduation, or visa change.
How to Register a Foreign Family Member as a Dependent
Dependent registration is one of the areas where foreign residents most often encounter delays. Requirements vary by family relationship and financial situation, but you may need:
- the dependent qualification acquisition/loss report;
- the applicant’s Residence Card or domestic residence card;
- a marriage certificate, birth certificate, or another official family-relationship document;
- confirmation or an Apostille when required;
- a notarized Korean translation if the document is not in Korean; and
- additional income, property, disability, or dependency documents.
NHIS currently states that foreign family documents used for dependent registration generally must have been issued or officially confirmed within nine months of submission. The documents should contain enough matching personal information—such as names and dates of birth—to identify the people and their relationship.
The main published income rule for an ordinary dependent is total annual income below KRW 20 million, but business income, rental income, property, marital status, age, cohabitation, and the type of relationship can change the result. Contact NHIS before paying for translation, notarization, or an Apostille so you know exactly what your case requires.
What Does NHIS Cover?
Foreign subscribers receive the same categories of national health insurance benefits as Korean subscribers. Covered services can include:
- visits to clinics and hospitals;
- diagnostic examinations and tests;
- treatment, surgery, and hospitalization;
- prescription medicine;
- rehabilitation;
- pregnancy and childbirth benefits in qualifying cases; and
- national health screenings for eligible subscribers and dependents.
You still pay the applicable patient share. As a general illustration, NHIS publishes a 20% patient share for covered inpatient treatment, 30% for ordinary outpatient treatment at local clinics, and 30% for ordinary covered pharmacy costs. Rates can be higher at hospitals and tertiary hospitals, and non-covered services can be charged entirely to the patient.
Always ask whether a treatment is covered by NHIS before agreeing to an expensive test or procedure. The useful Korean question is:
건강보험 적용돼요?<br>Geongang boheom jeogyong dwaeyo?<br>“Is this covered by national health insurance?”
How to Use NHIS at a Clinic or Hospital
- Bring your Residence Card or another accepted form of identification.
- At reception, give your name and identification information so the clinic can verify your insurance eligibility.
- Ask whether the service is covered if the expected cost is important.
- Pay your co-payment after treatment.
- Take the prescription to a pharmacy if medicine was prescribed.
In an emergency, call 119. For other useful numbers—including police, medical information, immigration, and tourist assistance—see our complete guide to emergency numbers in Korea.
What If You Already Have Private or Overseas Insurance?
Holding private travel, employer, or overseas insurance does not by itself cancel NHIS enrollment. A limited exclusion process exists for some foreign or overseas-Korean employees who can prove they receive medical coverage equivalent to Korean national health insurance under foreign law, foreign insurance, or an employer contract.
The exclusion is not automatic, and NHIS requires an application and supporting evidence. The official guidance also sets timing requirements. Speak with NHIS and your employer before assuming that foreign insurance exempts you.
Common Problems and How to Fix Them
“I have lived in Korea for six months but received no bill.”
Check your registered address and insurance status with NHIS. A missing paper bill does not necessarily mean you have no premium obligation.
“My employer has not enrolled me.”
Ask payroll whether your workplace and employment are covered and request confirmation of the reported eligibility date. Contact NHIS if the explanation is unclear.
“My premium is higher than my friend’s premium.”
Visa status, employee versus regional enrollment, wages, household composition, income, property, reductions, and long-term care insurance can all change the amount. Compare your official assessment details rather than another person’s bill.
“My student reduction is missing.”
Confirm your school registration, residence status, income and property conditions, and the effective date with your university and NHIS.
“NHIS rejected my family documents.”
Ask which exact document, confirmation, Apostille, translation, issue date, or personal-information item is missing. Requirements are case-specific, so obtain a checklist before preparing the documents again.

Frequently Asked Questions
Is Korean health insurance mandatory for foreigners?
It is mandatory for many registered foreign residents. Employees at covered workplaces are generally enrolled through work, while many other eligible long-term residents become regional subscribers after more than six months. Short-term visitors and some residence categories follow different rules.
Can I use NHIS immediately after arriving in Korea?
It depends on your status. An eligible employee can generally obtain coverage through covered employment without waiting six months. Regional enrollment timing depends on residence status and the official calculation of your stay.
How much does Korean health insurance cost for a foreigner in 2026?
Employees pay half of the 7.19% health insurance contribution calculated from their insured wage, plus their share of long-term care insurance. For many foreign regional subscribers, the published 2026 average reference premium is KRW 158,630 per month including long-term care insurance, but personal assessments and reductions vary.
Can my spouse join as my dependent?
Possibly. The relationship, income, property, and dependency rules must be met, and foreign documents may require official confirmation, an Apostille, and a notarized Korean translation.
Does NHIS cover dental care?
Some dental services are covered, while many cosmetic, implant, orthodontic, or optional services may be partly covered or not covered. Ask the dental clinic for a covered-versus-non-covered estimate before treatment.
Final Checklist
Before your first NHIS bill or hospital visit, make sure you have:
- confirmed whether you are employee-insured, self-employed, or a dependent;
- checked the correct eligibility start date;
- updated your registered Korean address;
- reviewed your payslip or regional premium notice;
- confirmed any student or household reduction;
- prepared family documents before applying for dependent status; and
- saved 1577-1000 and 033-811-2000 in your phone.
Keep your first eligibility notice, premium bill, and payslip. If the subscriber category or amount is not what you expected, contact NHIS before the balance builds up. Rules and individual circumstances can change, so use this guide as a starting point and confirm important decisions directly with NHIS.
