French authorities have opened formal investigations into an alleged €58 million fraud against the national health insurance system, involving fictitious patients and billing for treatments never performed across multiple dental centres. The case, reported this week by Dentaire365 and 20Minutes, follows earlier enforcement actions in which the French health insurance system had already excluded several dental centres from reimbursement over irregular billing. What sets this case apart is its apparent scale and the organised nature of the scheme. According to the investigating magistrate, several dental centres began billing massively for fictitious procedures shortly after ownership changed hands at the end of 2024. Detection reportedly relied in part on an anonymous tip rather than routine oversight, raising questions about how effectively existing monitoring systems catch fraud before it reaches this scale. The European Federation of Periodontology and Preventive Dentistry (FEPPD) argues the case points to a systemic problem and calls for stronger transparency throughout the dental care chain. Specifically, FEPPD argues patients should have a clear, enforceable right to receive a copy of the dental technical invoice for their treatment. Giving patients direct access to this information would make it easier to identify discrepancies between prescribed, produced, and invoiced care at an earlier stage, reducing dependence on whistleblowers.
