In brief
Two main hospital buildings on the Asian side, run by Yeditepe University (founded 1996). The JCI story is told two ways on its own pages and names only Koşuyolu; Kozyatağı names no accreditation.
The hospital
What Yeditepe University Hospitals are
Yeditepe University was founded in 1996 and runs its hospitals under the Yeditepe University Hospitals name. Kozyatağı opened on 26 August 2005; Koşuyolu is the second main building. Other units named are a Dental Hospital, an Eye Center, a Genetic Diagnosis Center, a Complementary Medical Center and a Tissue Typing Laboratory.
The hospitals say they have patients from over 100 countries. They print no international patient unit page and no foreign office on the pages we read.

Campuses and what each states
Yeditepe University Koşuyolu Hospital
Kadıköy, Istanbul
Koşuyolu Mah. Koşuyolu Cad. No: 168, 34718 Kadıköy
- 180 beds, 6 intensive care beds, nine operating rooms.
- 35,000 m² indoors and nearly 100 doctors, per the hospital.
- The JCI claim names this building.
The JCI timeline
The About page says JCI first audited the hospital on 2 November 2007 and that it was "re-accredited for the fifth time in 2020". The JCI page says it was accredited in 2007, renewed in 2010, and met the eighth-edition academic medical centre standards in January 2025, naming only "Koşuyolu Specialized Hospital and Eye Center". These timelines do not match, and neither names Kozyatağı. Treat the claim as applying to Koşuyolu only until the register says otherwise.
Other certificates the hospitals list
ISO 15189:2023 for laboratories; ISO/IEC 27001 since 1 July 2016, re-accredited to the 2022 edition; the TÜSKA SAS Gold, with the recipient written as a "Specialized Practice and Research Center" on one page and "Koşuyolu Hospital" on another; a Baby-Friendly designation in 2009; and a Health Tourism Authorization Certificate in 2020 with no building stated.

Every register and professional body this guide relies on, so that the figures above can be checked at the organisation that publishes them rather than taken from us.
- 1.T.C. Sağlık Bakanlığı — Ministry of Health of Türkiye
Licenses every clinic and hospital operating in Türkiye, and issues the separate health tourism authorisation a facility needs before it may treat international patients.
- 2.T.C. Sağlık Bakanlığı, Sağlık Turizmi Daire Başkanlığı — authorised facilities and intermediary agenciesOfficial register
The Ministry's own index of who holds a health tourism authorisation certificate, linking the facility list and the intermediary list. This is the page to check a clinic against, and checking it takes about two minutes.
- 3.USHAŞ — International Health Services
The Ministry of Health's own body for international patients. Publishes which facilities hold health tourism authorisation, and takes complaints from patients treated in Türkiye.
- 4.Joint Commission International — accredited organisations registerThird-party accreditor
The public register of JCI-accredited hospitals. A hospital's accreditation is either in this register or it is not, which makes it checkable in a way that a badge on the hospital's own website is not.
- 5.TÜSKA — Türkiye Sağlık Hizmetleri Kalite ve Akreditasyon EnstitüsüOfficial register
The accreditation institute's own notice to authorised facilities about the 31 December 2026 deadline, and what it says will happen to those that have not completed the process. Its register of accredited organisations is where a claim to hold the accreditation can be checked.
Listing a body here is not a claim of endorsement by it. Where a figure could not be traced to a source of this kind, it was removed from the guide rather than published unattributed.
