Diederik Schrijvershof and Saskia Stolk successfully litigated at the Court of Appeal in The Hague on behalf of nineteen orthopaedic footwear providers. On 14 October 2025, the court ruled that Zilveren Kruis (ZK) must increase its 2025 rates for orthopaedic foot care by 29.9% from 1 January 2025.
In this ruling, the Court emphasised not only that ZK must index correctly, but also that cross-subsidisation is prohibited. The latter means that ZK (and this also applies to other healthcare insurers) may not demand that excessively low Zvw rates be compensated by (i) reimbursement for the same care by other healthcare insurers and/or (ii) other care provided by the healthcare providers concerned. This is the second time in eighteen months that Maverick Advocaten has been successful in summary proceedings against ZK before the Court of Appeal in The Hague to achieve realistic rates for healthcare providers.
Cost-covering rates and indexation in healthcare
In July 2024, Maverick Advocaten achieved success for ELD providers/hospitals with the STAR ruling. With the STAR ruling in hand, Maverick Advocaten subsequently also achieved success in 2024 in proceedings against VGZ for 23 providers of orthopaedic shoes, see here. Later, on 6 November 2024, summary proceedings against CZ were also won, see here. On 10 April 2025, summary proceedings against ONVZ were won for respiratory care providers, see here. On 24 September, summary proceedings against ONVZ were won for orthopaedic shoemakers:
Maverick Advocaten has previously achieved success in (preliminary relief) proceedings for healthcare providers in the procurement of, among other things, general practitioner care, acute mental healthcare (here and here), forensic care, youth care, SGLVG care, Wlz care, also in appeal and here and here, and Wmo care (see also here). Maverick Advocaten also achieved success in summary proceedings on behalf of seven mental healthcare providers against CZ Zorgkantoor (see also here).
Maverick Advocaten assists healthcare providers on a daily basis in achieving cost-covering rates in healthcare or in challenging inadequate (turnover) ceilings. For example, Maverick Advocaten litigated successfully on behalf of forensic mental healthcare providers against the NZa Rate Decision for mental healthcare and forensic care 2023 and 2024. In addition, Maverick Advocaten successfully litigated on behalf of the De Bevlogen Huisartsen foundation and 129 individual general practitioners against the NZa Tariff Decision for General Practitioner Care 2023. Maverick Advocaten also opposes abuses of purchasing power by health insurers, see also here.
