The center of gravity in global medical demand, once concentrated on K-beauty, plastic surgery, and dermatology tourism, is now expanding to include complex, serious conditions such as cancer, cardiovascular and cerebrovascular disease, and organ transplants. South Korea, once a country whose patients traveled abroad for treatment, is now emerging as a "global hub for treating serious illness" that draws patients with hard-to-treat conditions from around the world.
The 12 tertiary general hospitals and 14 general hospitals (26 in total) registered as Seoul medical tourism partner organizations form the core of Korea's healthcare system, spanning everything from advanced treatment for serious illness to precision, customized health checkups. Many of these major medical institutions rank among the world's best in major global hospital rankings each year, firmly establishing themselves as a hub for serious-illness care recognized around the world.
■Newsweek's Recognition: Korea's "Big 5" and Other Top-Ranked Hospitals
In the "2026 World's Best Hospitals" ranking published by the American newsmagazine Newsweek together with the market research firm Statista, Asan Medical Center ranked 25th in the world (1st in Korea) and Samsung Medical Center ranked 26th (2nd in Korea), both placing among the world's elite. Severance Hospital (39th) and Seoul National University Hospital (41st) followed, with these institutions — commonly grouped with Seoul National University Bundang Hospital as Korea's "Big 5" — demonstrating strong global competitiveness. Gangnam Severance Hospital also ranked near the top 100 worldwide, reflecting its strong treatment capabilities.
■Top Global Rankings by Specialty: Korea Dominates in Serious-Illness Care
In a separate Newsweek evaluation, "Asia-Pacific's Best Specialized Hospitals 2026," Korean hospitals' strength in serious-illness care stood out even more. Asan Medical Center ranked first in the Asia-Pacific in five specialties — cardiology, cardiac surgery, neurology, endocrinology, and orthopedics — and second in oncology, pulmonology, and gastroenterology. Samsung Medical Center ranked first in oncology, pulmonology, and gastroenterology, while Seoul National University Hospital ranked first in pediatrics for the Asia-Pacific region. In effect, Korean hospitals swept first place in nine of the ten specialty categories evaluated across the Asia-Pacific.
■One-Stop Fast Track Meets Specialized General Hospitals
The tertiary and general hospitals on this list operate specialized infrastructure for serious illness — dedicated cancer centers, cardiovascular centers, robotic surgery centers — alongside precision health-checkup programs, all under one roof. Through their international clinics, foreign patients receive "one-stop fast-track" support spanning pre-arrival consultation, admission and surgery, and post-departure follow-up care.
The list also includes general hospitals specializing in areas such as joint and spine care, women's health, neurology, and nuclear medicine, giving overseas patients the option to choose the treatment best suited to their condition.

FAQ
Q. Can foreign patients receive treatment for serious illness at Korea's tertiary general hospitals?
A. Yes. However, the share of hospital beds that tertiary and general hospitals may allocate to foreign patients is capped by law under the Medical Service Act, at 5% and 8% respectively. For this reason, advance consultation and scheduling through an international clinic before entering the country is essential.
Q. How do visa issuance and preliminary consultation work when entering Korea for treatment of a serious illness?
A. Prior to arrival, major hospitals' international clinics offer remote medical record reviews and remote one-on-one consultations. Once the treatment schedule is confirmed, the hospital provides the supporting documents required for a medical visa (C-3-3 or G-1-10) to expedite entry procedures.
Q. Can I receive a health checkup and treatment for a serious illness at the same time?
A. Yes. The international clinic coordinates checkup and specialist appointments together as a single, one-stop schedule. If an abnormality is detected during a comprehensive health checkup, the patient can be referred immediately to the hospital's appropriate specialized center.
Q. What criteria determine the world hospital rankings?
A. Newsweek and Statista calculate the rankings by combining recommendations from global medical professionals (doctors, hospital staff, etc.), hospital quality-of-care indicators, patient satisfaction surveys, and whether the hospital has adopted Patient-Reported Outcome Measures (PROMs).
