What to Check Before Booking a Renowned Doctor at a University Hospital

1. Prepare a physician referral letter – Seoul National University Hospital, Asan Medical Center and Severance Hospital are tertiary (advanced general) hospitals. To be covered by Korean National Health Insurance, you need a physician referral letter from a local clinic or general hospital.

2. Check whether the doctor is currently seeing patients – Some doctors on the list may no longer see outpatients due to retirement, a move to another hospital or reduced clinic hours. First check their clinic days and specialties via “Find a Doctor” on the hospital website.

3. Bring your test records – Bringing imaging (CDs), biopsy reports and medical opinions from other hospitals can help reduce repeat tests.

4. Consider the waiting time – Well-known doctors can have long waits for a first appointment. It is a good idea to also look into other specialists in the same department or partner hospitals.

Frequently Asked Questions (FAQ)

Q. Can I book directly with a doctor on Korea's renowned doctors list?

At most hospitals, you can book with a specific doctor through the main phone line, website or app. However, as these are tertiary hospitals, you need a physician referral letter to be covered by Korean National Health Insurance, and waits can be long depending on the doctor.

Q. Is the Seoul National University Hospital renowned doctors list still accurate?

The list in this article is taken from material published in August 2025. Some doctors may have since retired or moved to another hospital, so check on the hospital website whether they are currently seeing patients.

Q. Should I go to Asan Medical Center or Severance Hospital?

It is hard to say that one is always better. We recommend weighing the disease area, distance from home, waiting time and whether a hospital already has your previous test records, and decide together with your doctor.

Q. Are Severance Hospital and Gangnam Severance Hospital the same hospital?

Both belong to Yonsei University Health System, but they are separate hospitals with different locations and main phone numbers. Severance Hospital in Sinchon is 1599-1004, and Gangnam Severance Hospital is 1599-6114.

Q. What happens if I go without a physician referral letter?

You can still be seen, but Korean National Health Insurance will not apply, so your medical costs may rise significantly. It is better to first get a physician referral letter from a nearby clinic.
