At the time of its opening in 1989, the clinic was mainly responsible for primary care for foreigners traveling or living in Korea. Nowadays, as the news of Seoul Asan Medical Center's unparalleled treatment performance is spreading through various media overseas, the number of foreign patients visiting the clinic from overseas (such as the United States, Russia, Mongolia, and the Middle East) is increasing, and the clinic has formed an international referral team to provide services such as coordination, interpretation, and medical billing so that foreign patients can return home without any inconvenience.

In addition, the International Medical Center provides Korean patients with English documents after physical examinations for studying abroad or working abroad.
