What does “actual costs” mean ?

The actual costs are the amount you actually spend.

Often, insurance reimburses you according to the Social Security reimbursement base.

Example: If an insurance pays you 300 from the Social Security reimbursement base, you will only receive 69 euros for a consultation with a general practitioner because the convention fee for a consultation is 23 euros, or 23-300 – 69 euros. In high-medical countries such as the United States, this type of medical expense can amount to more than $150. It is essential to be reimbursed on the basis of your actual expenses.
