Meyerlustenberger Lachenal advised 26 medico-welfare institutions

In 2011, the Swiss Federal Council changed its Ordinance on Health Care Insurance Benefits, amending the list of benefits payable under the compulsory health insurance scheme. Following this amendment, several insurance companies refused to reimburse certain services provided by medico-welfare institutions. As of 2012, Meyerlustenberger Lachenal (MLL) advised 26 of these institutions, all based in Geneva. After the Swiss Federal Court ruled that such costs were indeed to be borne by the compulsory health insurance providers, agreements have been reached with the insurance companies allowing medico-welfare institutions to obtain the reimbursement of over 8 million Swiss Francs, representing accrued (unpaid) costs between 2011 and 2019.

MLL acted as legal advisor to  26 medico-welfare institutions. The was composed from senior partner Philippe Prost and partner Cosima Trabichet-Castan, as well as junior associate Sophie Bastardoz (all litigation).
