Reimbursement processing

IMPORTANT: Processing times can vary from 6 to 9 weeks.

Acknowledgement of receipt

We cannot confirm receipt of a reimbursement request as long as the corresponding invoices have not been processed by our team in charge.

We thank you for your understanding and patience.

Processing your request

Once the CNS starts processing your request, it goes through a series of procedures.

For example :

Invoices

  • most invoices are scanned first
  • the system then performs optical recognition. If necessary, the CNS agents have to go through the various electronic documents and perform the necessary corrections
  • once the invoice has been validated, it will be settled by our accounting department within a few days
  • after this settlement, the bank accounts are credited according to the different bank deadlines (a national bank account will be credited faster than an international bank account)

Dental quotations

  • the files are administratively controlled and filed by the CNS
  • they are then sent to the Medical Board of the Social Security (Contrôle médical de la sécurité sociale - CMSS) for medical assessment
  • the CNS awaits the opinion of the CMSS before granting or refusing coverage

Refund period

The refund period by bank transfer - from the time your request is sent to the time the refund is received in your bank account - is ideally 2 weeks.

However, between the date on which the CNS starts processing your request and the date on which you receive your reimbursement/return from the CNS, the time may vary significantly, from a few days to several weeks, depending on the workload, the resources available, etc.

In addition, invoices and fee notes sent in the same envelope are not necessarily processed together and may therefore be reimbursed at different times.

You may continue to receive a CNS reimbursement by cheque or by instant payment by making an appointment at one of our agencies http://guichet.lu/rdv-cns
