Asking for prior authorisation

Sometimes you need our permission before you can receive health care. We call this authorisation. The costs will not be reimbursed to you unless you have our permission. Below you can read when and how you need to request our permission. This applies to ONVZ Vrije Keuze and ONVZ Bewuste Keuze. If a certain type of health care only applies to one of these, it will be stated in the notes.

Here is how to request permission for health care


Step 1: Complete the application
The application form you need to use depends on the type of health care. The overview below shows you which application form to use for each type of health care. It also states which details and documents you need for your application and how you can submit the application. 


Step 2: Send the application to ONVZ
Once you have completed the application form, you can send it to us. The overview below shows you where you need to send the application. After you've submitted it, ONVZ will send you an email to confirm receipt. 


Step 3: ONVZ will assess the application
You will hear from us within 7 working days. A period of 10 working days applies to health care abroad.
