One of the greatest perks of living in South Korea is its healthcare system. It’s fast, efficient, and technologically advanced. If you are an expat paying into the National Health Insurance (NHI), you have access to medical services that would cost a fortune in many other countries.
Here is how to navigate the system like a pro and take advantage of the biennial free health check-up.
1. The "Free" National Health Check-up (Guk-ga Geom-jin)
If you are an NHI subscriber, you are entitled to a comprehensive health check-up every two years (usually determined by whether your birth year is even or odd).
What's included? Blood tests, chest X-rays, urine analysis, blood pressure, and even cancer screenings (depending on your age).
The Cost: Mostly free or 10% co-pay for certain cancer screenings.
How to book: You will receive a notification in the mail or via the 'The Health' app. Simply call a designated hospital and say, "Guk-ga geom-jin ye-yak-hago sipeoyo" (I want to book a national health check-up).
2. Smart Tips for Expats
National Health Insurance (NHI) Card: You don't actually need the physical card! Just show your ARC at the desk, and they will find you in the system.
Pharmacies (Yag-guk): After your doctor's visit, you'll get a paper prescription. Take it to any nearby pharmacy. Medication is incredibly affordable in Korea.
The "Health Insurance for Foreigners" Hotline: If you have questions about your coverage, call 033-811-2000 (English, Chinese, Vietnamese, and more available).
3. "A Life-Saving Routine": An Expat's Review
"Back home, I rarely went to the doctor because of the cost and waiting times. In Korea, I went to a local clinic for a cold, saw a doctor in 5 minutes, and paid less than 10,000 KRW for the visit and medicine.
Last year, I did my first free National Health Check-up. It was so organized—like a factory of health! They found a minor issue I didn't know about, and I was able to treat it early. It’s a benefit every expat should use. Don't skip it!"

4. Essential Medical Phrases
"A-pa-yo" (아파요): It hurts / I'm sick.
"Yeo-gi-ga a-pa-yo" (여기가 아파요): It hurts here (point to the area).
"Cheo-bang-jeon ju-se-yo" (처방전 주세요): Please give me the prescription.
"Sil-bi-bo-heom seo-ryu ju-se-yo" (실비보험 서류 주세요): Please give me the documents for private insurance (if you have extra private insurance).
