The Nederlandse Zorgautoriteit (NZa, Dutch Healthcare Authority) fixes healthcare tariffs in the Netherlands; these are maximum tariffs. You can find the NZa tariffs on the website of the NZa (only in Dutch).
If you think the healthcare provider charged you too much, you can report this at the NZa (only in Dutch). The NZa then checks whether the healthcare provider has complied with the rules and acts if necessary.
In case of hospital care, part of the costs are not determined by the government. It is therefore possible that you would pay a different price for the same treatment at different hospitals. You can obtain information about the costs of the treatment you want only from the healthcare provider or the hospital from which you want to receive treatment.
On their invoices, Dutch hospitals do not state every activity separately (for example, injections, scans, tests or examinations) but they only state combined diagnostic and treatment trajectories (‘DBC care products'). Each care product has its own code and rate.
You can read more about hospital invoices on the information card issued by the Dutch Healthcare Authority, NZa (only in Dutch): "Betalen van ziekenhuiszorg" ("Payment of hospital care" - only in Dutch). This sheet shows how Dutch hospitals draw up the bills.
If you wish to know what type of care is covered by the DBC care product shown on your invoice, you can use the DBC care product rates application on the NZa's website (only in Dutch).
The costs for treatment in Dutch hospitals can be high compared to the reimbursement you receive for the same treatment in your own country. Possibly you won’t get reimbursed all the costs if you first pay for the treatment yourself.
