The Competition and Markets Authority (CMA) has published an open letter to confirm that it is escalating its public enforcement action against private hospitals and consultants. The CMA’s Private Healthcare Market Investigation Order 2014 includes measures to increase the availability of information to patients on both consultant fees and the performance of consultants and private hospitals. To achieve this, private hospitals and consultants are required to provide information to the Private Healthcare Information Network (PHIN). The letter explains that the hospitals and consultants that are still not fully compliant can seek help from PHIN to gain full compliance. It also warns those hospitals and consultants who have not made the effort to comply with the order, that the CMA is escalating its public enforcement action. The CMA will be publishing public announcements about this enforcement work shortly.
