What can I do if I have questions about my invoice, or if I do not agree with (the amount of) the invoice?

If you have any questions about your fracture or if you do not agree with your invoice, you can contact the financial administration of general practitioners OZL, available on Mondays, Tuesdays and Thursdays from 8:30 a.m. to 4:30 p.m. and on Wednesday mornings from 8:30 a.m. to 12:00 p.m. on 045 – 747 00 40 and via debiteuren@hozl.nl. The rates are set annually by the Healthcare Rates Board. We have to stick to that.
