Asking for prior authorisation

You should request prior authorisation for health care to tackle overweight and obesity in children. You can do so with our application form. You fill in one part of the form yourself. The other part should be completed and signed by your health-care provider. Make sure the form is fully completed before sending it to us.

• Application form guidance and coordination central health-care provider (centrale zorverlener - CZV) and combined lifestyle intervention (cli) children
• Application form to extend the interim period

Where should you send the application?
To ONVZ, using the upload form. Or send in the form by post.

If you need non-urgent transportation by ambulance over a distance greater than 200 km, or if you need other means of transport, you need our prior approval. Your healthcare provider will apply for this approval with a written explanation of why the transport is necessary. Our permission is not required in urgent situations.

If you go abroad for healthcare, you need prior authorisation in the following cases:

1. If you need authorisation for a certain type of health care in the Netherlands, you also need it abroad. If you wish to go to a foreign hospital for plastic surgery, for example. Refer to the 'Plastic surgery' coverage for the conditions.
2. Admission for one day or more. In this case, refer to 'Abroad: (day) admission' below.

Even if you do not need prior authorisation, we still advise you to apply for it. This gives you certainty about whether the costs are covered and how much will be reimbursed.

Your request for prior authorisation should include, at the least:

• Referral from a GP or the doctor you are under treatment of in the Netherlands, stating the reason for the referral
• Explanation of why you want to go abroad for this care
• Treatment plan
• Itemised quotation  

Reimbursement according to the rules of the country where the care takes place

If you live in a country that is an EU/EEA member state or a treaty country and you receive the health care in another EU/EEA member state or Switzerland, you can opt for reimbursement according to the rules of the country where you receive the treatment. This applies to surgery or a hospital admission, and only when:

1. you cannot get that care in the Netherlands, or
2. you would have to wait too long for this care given your medical condition

You will need a so-called S2 form to do so. Apply for this form at least 10 working days before treatment starts using the S2 application form. You fill in one part of the form yourself. The other part should be filled in and signed by your physician abroad. Send us the form together with the referral and treatment plan. Make sure that the form is filled in completely.

Where to send your application?
If your application is related to medical-specialist care, use the online application form (NL). For other types of care, you can use the contact form. Or send in your application by mail.

If you are going to a foreign hospital or private clinic to be admitted, you need prior authorisation from ONVZ. This does not apply for emergency admissions, but please contact our Zorgassistance emergency centre in that case.

If you are going abroad for another kind of treatment you may also need our permission. See 'Abroad: non-urgent (scheduled) health care' above.

What is a (day) admission?
Day admission means that your treatment - in a day admission nursing ward - lasts longer than two hours, but you will go home the same day. For a regular admission you will stay in the hospital for at least one night.

Consultations and diagnostics
If you are visiting the hospital for just a consultation or an examination, such as an MRI, CT scan or colonoscopy, you do not need to apply for authorisation.
Please note: if an examination indicates (day) admission is required, you do need our approval for that (day) admission.

Exception
If you go to one of the following hospitals for a (day) admission, you do not need our prior approval. We have made special arrangements with these healthcare providers.

The maximum reimbursement limits apply to ONVZ Bewuste Keuze. 

We have agreed with the health-care providers above that they will send their claim directly to ONVZ. If the costs are higher than the level of coverage, we will bill you for the portion we do not reimburse.
