Waiting times and prices on your website: what the NZa asks

The general rule (TH/NR-035)

Since 1 September 2024, the NZa’s transparency regulation TH/NR-035 applies to anyone providing care professionally within the meaning of the Dutch Healthcare Market Regulation Act: care under the Health Insurance Act or the Long-term Care Act, and individual healthcare by BIG-registered professionals or holders of a protected training title. Physiotherapy, district nursing, mental health and dental care are covered. Support under the Social Support Act (Wmo), such as domestic help or municipality-funded day care, generally is not.

• Inform clients about relevant prices (Art. 4(3)) and own payments (Art. 4(6)).
• Before care starts, actively and demonstrably tell the client whether you have a contract with their insurer (Art. 4(5)).
• "The care provider makes waiting times transparent" (Art. 4(8)).

Information can be given orally, in writing, digitally or otherwise. The regulation does not require a website, but the website is where clients look first.

Waiting times on your own website, by sector

Mental health (ggz): the NZa states that publishing waiting times on a website is mandatory. Regulation NR/REG-2219a requires the registration and treatment waiting times in weeks, per location and per main diagnosis group, per insurer where they differ, with the date of the last update, refreshed at least monthly between the 1st and 10th. Since 1 January 2026 single-location providers no longer submit waiting times to the NZa, but we found no change to the website duty.

Hospital and specialist clinics (NR/REG-2421) submit waiting times to the NZa and must publish a fixed text per location about the Treeknorm (waiting-time standard) and waiting-list mediation by insurers. Dementia case management (NR/REG-2122): the regional dementia network publishes waiting times; your website must say where to find them, for example with a link. This matters for home-care organisations offering case management.

Price lists for allied health and dental care

Allied-health providers without an insurer contract must have a standard price list with all services, a start date and a fixed sentence, displayed clearly in the practice, given by phone on request and sent within two working days (NR/REG-2620). The current regulation does not mention the website; putting it online is still sensible. See websites for physiotherapy.

Dental practices with a website must publish their price list for material and technical costs there. A cost estimate is required for treatments from 250 euros, always in writing or digitally from 500 euros; the 2027 regulation keeps these amounts.

Why "it’s on the website" is not always enough

The explanatory notes to TH/NR-035 say information the patient has to find themselves, such as a website notice, is not sufficient to tell them you have no contract with their insurer. Do it actively before care starts, in the registration confirmation or intake, and record it.

Common mistakes

• Waiting times without a date, or months out of date.
• "We have contracts with all major insurers" without a list.
• The price list only as a PDF three clicks deep.
• One mental-health waiting time for the whole practice when locations differ.
