CERN Health Insurance Scheme (CHIS)

As an international organization CERN has its own mutual health insurance: the CERN Health Insurance Scheme (CHIS). It provides health insurance for active, retired and former members of the CERN personnel and for their families. The benefits, conditions, procedures and the contribution levels are defined in the CHIS Rules. The CHIS Information Notes provide further explanation to certain benefits or procedures.

The CHIS is administrated by a third party administrator, UNIQA, whom you may contact for further information and advice or with queries concerning membership, your coverage or the calculation of your reimbursements.
