Work stoppage: a new mandatory paper form
Publié le 28 mai 2025 - Mise à jour le 28 août 2025 - Directorate of Legal and Administrative Information (Prime Minister)
A new paper Notice of Work Stoppage (AAT) form is available. Required on 1er in september, this more secure form is designed to combat fraud.
In 2024, the financial damage detected by the Health Insurance for false work stoppages amounted to more than 30 million euros (compared to 8 million in 2023). The sale of fake work stoppages on social networks or on the internet is at the origin of this sharp increase.
In order to combat these practices effectively, the Health Insurance provides a new Cerfa form of notice of work stoppage that is difficult to falsify and more secure.
This paper form, which is mandatory in certain situations such as home visits, includes the following:
- special paper;
- a holographic label;
- magnetic ink;
- prescriber identification traits, etc.
This paper form, the use of which is encouraged by the Health Insurance, is available to order on amelipro.
Its use becomes mandatory from 1 september 2025 for any sending of paper work stoppage notices. As a result, Cerfa work stoppage forms that can be completed and printed from prescription software will be rejected by health insurance organizations from that date. The same applies to the scanning and photocopying of a work stoppage.
FYI
The Health Insurance recalls that the teletransmission via amelipro of a notice ofdematerialized work stoppage remains the means more secure to avoid usurpation and fraud.
