France to Ban Unverifiable Paper Sick Leave Certificates by June 2025

Cnam introduces secure digital forms to combat a surge in fraudulent claims tied to organized social media schemes.

Cnam reported €42 million in fraudulent sick leave claims in 2024, marking a 240% increase from the previous year.
A new secure Cerfa form for sick leave certificates, featuring QR codes and other security measures, is being implemented across healthcare providers.
From June 2025, paper sick leave certificates that cannot be verified will no longer be accepted by the French health insurance system.
Fraudulent sick leave schemes have become increasingly professionalized, with social media platforms being used to sell fake documents and recruit participants.
Cnam has doubled its fraud detection and prevention efforts over the past five years, achieving significant progress in addressing these challenges.
