# Can medical expenses not fully reimbursed by the CNS (or a mutual insurance company) be reported?

Medical expenses (treatment, medication, physiotherapy, etc.) that are not or are only partially reimbursed by the CNS or your complementary health insurance may be considered as extraordinary expenses.

You will need to provide all the necessary supporting documents to prove that you have not been reimbursed by the CNS or your complementary health insurance, such as invoices, till receipts and reimbursement statements from the CNS and possibly your complementary health insurance (CMCM, DKV, Medicis).

It is crucial that you only take into account the costs you actually had to pay.

For example, if your dental costs amount to €10,000 and the CNS and your supplementary health insurance have only reimbursed a total of €3,000, you can indicate the remaining €7,000, which represents the amount actually paid by you.

However, the total extraordinary expenses must be higher than your normal expense threshold in order to be deductible!
