CERN Health Insurance Scheme (CHIS)

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.
