Korea’s National Health Insurance Service (NHIS) provides free preventive health checkups to all enrolled adults on a biennial schedule. For expats, these checkups are genuinely useful — comprehensive screenings that would cost hundreds of dollars in many countries are provided at no cost. This guide explains who’s eligible, what’s included, and how to actually book and attend your checkup.
1. Who Gets a Free Checkup in 2026
NHIS checkups operate on a two-year cycle based on birth year:
- 2026 checkup year: People born in even years (1990, 1988, 1986, etc.) are eligible. The last digit of your birth year being even (0, 2, 4, 6, 8) is the quick check.
- Odd birth years (1991, 1989, 1987…) were eligible in 2025 and will next be eligible in 2027
- Employees (직장가입자): Eligible annually if your employer is enrolled in the workplace health checkup program (most employers with 5+ employees are)
- Local subscribers (지역가입자): Biennial eligibility based on birth year
Foreign residents enrolled in NHIS (which includes all long-term visa holders after 6 months of residency) are eligible on the same terms as Korean nationals.

3. Cancer Screenings (암검진)
Separate from the general checkup, NHIS provides targeted cancer screenings on a regular schedule. These have different age and risk-based eligibility requirements:
| Cancer Type | Eligible Group | Frequency | Test |
|---|---|---|---|
| Gastric (stomach) | Age 40+ | Every 2 years | Endoscopy or upper GI series |
| Breast | Women 40+ | Every 2 years | Mammogram |
| Colorectal | Age 50+ | Every 2 years | Fecal occult blood test; colonoscopy if positive |
| Cervical | Women 20+ | Every 2 years | Pap smear |
| Liver | High-risk groups (Hepatitis B/C, liver cirrhosis) | Every 6 months | Ultrasound + AFP blood test |
| Lung | Age 54–74, 30+ pack-year smoking history | Every 2 years | Low-dose CT scan |
Cancer screenings for eligible groups are provided at significantly reduced or zero cost-sharing.

4. The Employer Checkup (직장건강검진)
If you’re employed at a Korean company, your employer is legally required to facilitate annual health checkups for employees under the Industrial Safety and Health Act. Key points:
- The employer (or their designated checkup provider) notifies you of your checkup schedule
- You must complete the checkup within the calendar year
- If an employee doesn’t complete their checkup and the employer failed to facilitate it: fines up to ₩10,000,000 per unfulfilled employee
- The checkup is done during work hours at an approved medical institution (건강검진기관)
- For expats: your employer’s HR team will coordinate this; participation is expected as part of standard compliance
5. How to Check Your Eligibility and Book
Check eligibility:
- Log in to NHIS (nhis.or.kr) using your foreigner registration number
- The NHIS Health-in app (건강인 앱) shows your current checkup eligibility and history
- You’ll typically receive a notification letter (건강검진 안내문) at your registered address
Book your checkup:
- On NHIS website: search for approved checkup institutions (건강검진기관) near you
- Contact the institution directly by phone to book a time — most speak Korean; some larger hospitals have English-speaking staff
- At booking: mention you’re a foreigner if you need language assistance — many hospitals have English-speaking coordinators for major checkup items
6. What to Bring and What to Expect
On checkup day:
- Fast from midnight the night before — blood tests require fasting; water is allowed
- Bring your Alien Registration Card (ARC) and health insurance card (건강보험증) or the checkup notification letter
- Wear comfortable clothing that’s easy to remove for the physical exam
- The full checkup takes approximately 1–2 hours depending on the institution and additional tests ordered
Results are typically delivered within 2–4 weeks, via the NHIS portal or by mail. The report is in Korean — medical translation apps or the hospital’s patient portal often provide summaries.
7. What the Checkup Doesn’t Cover
The free NHIS checkup is preventive screening — it’s not a substitute for specialist care:
- Not covered: mental health treatment, ophthalmology, dentistry (beyond basic oral screening), dermatology, OB/GYN beyond cancer screening
- If a screening result requires follow-up, you visit the appropriate specialist through the standard outpatient system (cost-sharing applies)
- The checkup results are used for population health data — they’re not a comprehensive medical evaluation
Frequently Asked Questions
Q: I moved to Korea in mid-year. Am I eligible for the free checkup this year?
A: Once enrolled in NHIS (required for long-term visa holders after 6 months, earlier by choice), you become eligible on the standard biennial schedule. Check nhis.or.kr with your foreigner registration number to see your current status.
Q: My checkup letter is in Korean and I don’t understand it. What should I do?
A: The letter contains your checkup eligibility year, the deadline (usually December 31), and instructions to book at an approved institution. The NHIS website has an English interface that shows the same information digitally — log in with your foreigner registration number.
Q: Can I get the gastric endoscopy instead of the upper GI series for the cancer screening?
A: Yes — for the gastric cancer screening, you can choose between upper GI (barium swallow) or endoscopy. Endoscopy is more accurate; most Koreans choose it. You may be asked to pay a small additional fee depending on the institution.
Q: What happens if I miss my checkup year?
A: For NHIS checkups, missing your eligibility year means waiting until the next biennial cycle. For employer-mandated checkups, your employer faces potential fines if completion rates fall below compliance thresholds.
