As an intergovernmental organization, CERN has its own health insurance: the CERN Health Insurance Scheme (CHIS).
The main purpose of the CHIS is to safeguard its Members against the financial consequences of illness, accidents and maternity by providing reimbursement of expenses arising from medical treatment. A Third-Party Administrator operates the CHIS: UNIQA, whom you may contact for further information and advice, for queries concerning your coverage, the calculation of your reimbursements or your membership.

CERN Health Insurance Scheme (CHIS) – Temporary relocation of UNIQA office to Building 55

Please note that the UNIQA office, previously located in the Main Building on the Meyrin site, has been temporarily moved to Building 55 at Entrance B.

The UNIQA office is in Building 55 from 8 April 2025 until the end of the refurbishment in the Main Building expected in October 2025.

Parking at Entrance B is limited to 30 minutes and there is an accessibility parking place available.

The UNIQA letterbox in the Main Building will be closed during the relocation but one has been installed in Building 55 but it is accessible only during the help desk opening hours. 

One can also be found on the ground floor in building 33 – CERN Community Support Centre (CCSC) and it is accessible from 7 a.m. to 6.30 p.m from Monday to Friday. It is also possible to send documents to UNIQA by internal mail.
