How Korea's National Health Insurance Scheme (NHIS) works for foreign ESL teachers — enrollment, premiums, coverage, using clinics, and what supplemental insurance you need.
Korea's NHIS covers 65–70% of medical costs. Teachers working 60+ hours/month are enrolled automatically. Premium is ~3.6% of salary (2026 rate), split equally between employer and employee.
ESL teachers working 60 or more hours per month are automatically enrolled in NHIS by their employer within 14 days of starting work — no separate application is required.
Your employer registers you with the National Health Insurance Service (국민건강보험공단, NHIS) and deducts premiums directly from your salary. You should receive a physical health insurance card (건강보험증) within 2–4 weeks of your start date — this can also be downloaded digitally through the NHIS app or website. If your employer has not enrolled you within one month, contact the NHIS directly (1577-1000, English available) as unenrollment is a violation of the Employment Insurance Act. Part-time teachers working fewer than 60 hours/month may be eligible for voluntary enrollment at a flat community rate.
The NHIS premium is 7.19% of your monthly salary (2026 rate), split 50/50 between you and your employer — you pay approximately 3.6%, which on a 2.3M KRW salary is roughly 82,800 KRW/month.
NHIS covers 65–70% of the cost for most outpatient visits, hospital stays, prescribed medications, and procedures. A typical GP visit at a local clinic (의원) costs 5,000–15,000 KRW after insurance coverage. Emergency room visits and specialist consultations are covered at a lower rate (50–60%). Major procedures and inpatient care are covered more generously, with patient co-pays typically capped. The NHIS system is cashless for insured services — present your health card and pay only your co-pay portion at the point of service.
Present your NHIS card at any registered clinic or hospital, pay the co-pay amount, and collect your prescription at a nearby pharmacy — the system works without prior authorization for most services.
Korea uses a tiered healthcare system. Local clinics (의원) handle general illnesses and cost the least. General hospitals (병원) treat more complex cases. Tertiary hospitals (종합병원) like Severance or Asan require a referral from a lower-tier provider except in emergencies. Prescriptions must be filled at a separate pharmacy (약국), usually located right outside any clinic. Many clinics in major cities have English-speaking staff. The government's "Medical Korea" helpline (1588-5800) provides free English medical interpretation. Keep all receipts for insurance documentation and potential tax filing.
NHIS does not cover most routine dental care, vision correction, or cosmetic procedures — supplemental private insurance is strongly recommended for comprehensive coverage.
Basic dental cleanings and cavity fillings are partially covered, but orthodontics, implants, and most prosthodontics are not. Standard eye exams are covered, but glasses and contact lenses are excluded. Mental health coverage under NHIS has improved significantly — psychiatry visits and counseling are now reimbursed at standard co-pay rates, though the stigma around seeking care varies by provider. Supplemental insurance for foreign workers is available from providers like Mercer, Cigna, and AXA for 30,000–80,000 KRW per month. These plans typically add comprehensive dental, vision, and international coverage.

This is illegal. Contact NHIS directly at 1577-1000 (English available) and report your employer. You may also retroactively enroll and claim reimbursement for medical costs you paid out of pocket during the unenrolled period.
Yes. NHIS does not exclude pre-existing conditions — all covered services are available from enrollment. This is one of the significant advantages of the Korean system compared to many private insurance plans.
Yes. Major cities have internationally-staffed clinics. The government's Medical Korea website lists English-capable hospitals by city and specialty. In Seoul, areas like Itaewon and Gangnam have many English-speaking providers.
Psychiatry and psychology services are covered at standard NHIS co-pay rates (typically 30–40% patient share). Initial visits may cost 10,000–25,000 KRW. Some counseling services are also covered, though session limits may apply.
NHIS coverage ends when your employment ends. You can switch to voluntary coverage (지역가입자) within your remaining visa period by contacting NHIS directly. Monthly premiums for voluntary coverage are assessed on income or a minimum flat rate.
