From July 1, 2023, certificates of incapacity for work can be forwarded to the CNS (Caisse Nationale de Santé) via the e-mail address The address will be deactivated, and e-mails will not be forwarded or processed. It is important for the employee to ensure that the CNS has received the certificate. Therefore, we encourage you to communicate this information to them.

Also, MDE (Mutualité des Employeurs) reimbursements for COVID-19-related absences (quarantine, isolation) will be made at the same 80% rate as for other work incapacities, with effect from the April 2023 reference period. As a reminder, it had been planned for these absences to be reimbursed at 100% by the MDE during the crisis period.
