Towards enhanced cooperation between Health Insurance and mutuals to combat fraud and improve reimbursements

Fraud in Health Insurance represents a major challenge for the French healthcare system, with the extent of diverted funds reaching several hundred million euros annually. Faced with this reality, the need for increased collaboration between the Health Insurance and mutual organizations such as Harmonie Mutuelle, Groupama, Swiss Life, or AG2R La Mondiale becomes increasingly evident. This approach, offering a double advantage, aims not only to strengthen the fight against fraudulent practices but also to optimize reimbursement processes for insured individuals. In 2024, the National Health Insurance Fund (Cnam) has already prevented more than 628 million euros in fraud, figures that underscore the relevance of a coordinated and better-equipped strategy.

In this context, recent parliamentary debates and legislative proposals highlight potential avenues for improving this synergy between mandatory Health Insurance – which manages public expenditure – and traditional mutual organizations that are partners of insured individuals. The Social Security Financing Bill (PLFSS) 2025 includes amendments aimed at facilitating the exchange of confidential information within strict frameworks, a key point for dismantling fraudulent networks while respecting the rights of insured persons. Organizations such as the French Mutuality advocate for broader sharing of data. The ambitious goal is to limit social fraud, estimated at nearly 13 billion euros annually, and by extension, to envisage a gradual transfer of 3 billion euros of expenses to mutual organizations by 2030, thus easing the financial burden on Health Insurance.

This dual system, inherited from the post-war era, shows its limits in managing complex cases, controls, and reimbursements. The argument for enhanced cooperation relies on the complementarity of actors, with mutual organizations having access to additional data and closer monitoring of members, while Cnam holds the state domain, guaranteeing rules and budgets. These exchanges could facilitate the detection of fraudulent behaviors, abuse prevention, and the rationalization of procedures, directly affecting the quality of service to insured individuals. To delve deeper into this topic, various mutual organizations such as MMA, Melia, and Mutuelle de Poitiers are actively engaging in discussions, aiming for a more unified vision of the healthcare system.

Current State of Fraud in Health Insurance: Figures and Current Challenges

Social fraud, particularly in the field of Health Insurance, is one of the main destabilizing factors of the French healthcare system. Estimates suggest total amounts around 13 billion euros per year. This phenomenon covers a broad spectrum: false declarations, overbilling, abuse in prescriptions, diversion of benefits, or identity theft. In 2024, Health Insurance revealed a record amount of 628 million euros in detected fraud, a figure that reflects both increased efficiency of detection mechanisms and persistent malicious behaviors.

The diversity of fraud types requires a multi-actor and multifactorial approach. Health Insurance alone cannot curb the phenomenon, as it manages 500 billion euros in healthcare expenses annually and works with millions of insureds, making oversight complex. Meanwhile, supplementary health insurers, including entities like Harmonie Mutuelle, MMAMacicf, and AG2R La Mondiale, cover tens of millions of members and possess valuable data on care histories and supplementary reimbursements.

In response to this reality, measures have been progressively implemented to improve controls. These include targeted actions by regional health agencies, computerized verifications, and more rigorous conformity tests of invoices issued by professionals. However, the fight remains insufficient if information exchanges between Health Insurance and mutual organizations are hindered by legal and technical barriers.

• Fake medical certificates to obtain abusive sick leave.
• Overbilling medical devices, especially in the hearing aids sector.
• Multiple simultaneous reimbursement requests for the same procedure.
• Identity theft by third parties to obtain benefits.

Type of fraud 🔒	Estimated annual amount 💰	Involved actors 🤝	Ongoing actions ⚙️
Abusive sick leave	150M €	Health Insurance, Mutuals	Enhanced controls, medical verifications
Overbilling & fictitious invoicing	220M €	Healthcare professionals, Mutuals	Audits, recovery, sanctions
Identity theft	80M €	Insured individuals, Mutuals	ID checks, alerts
Multiple reimbursements	178M €	Health Insurance & Supplementary insurers	Cross-analysis of data

The fight against these frauds is central to discussions regarding the PLFSS 2025. Regulatory measures could extend the powers of mutual organizations to perform verifications and create secure shared databases. The stakeholders targeted by these proposals include major players in the sector, such as Swiss Life, MMA, Melia, Mutuelle Générale, and Mutuelle de Poitiers, all committed to increased transparency.

Legal and Regulatory Barriers to Smooth Cooperation Between Health Insurance and Mutual Organizations

Despite recognized interest in strengthening collaboration between Health Insurance and mutuals, several legal and regulatory barriers complicate the implementation of a fully operational information exchange system. The main obstacles concern the protection of personal data, medical confidentiality, and the respective responsibilities of organizations within the current legal framework.

The General Data Protection Regulation (GDPR), in force since 2018, strictly governs the processing of health data. All communication must comply with principles of purpose, transparency, and prior consent of the concerned individuals. While Health Insurance and mutuals are essential partners, they operate within distinct legal frameworks: one a public body governed by the Social Security Code, the other private mutual organizations subject to the regulation of the Prudential Supervision and Resolution Authority (ACPR).

This duality entails risks in sharing information, both for data security and the legitimacy of controls. Furthermore, recent jurisprudence warns against practices perceived as discriminatory or infringing on insured persons’ rights, which hampers overly ambitious automatic data exchange initiatives.

• Limits imposed by medical confidentiality and the need for insured consent.
• The strict framework for handling sensitive data under GDPR.
• The complication of responsibilities in case of processing errors or abusive sanctions.
• The risk of privacy breaches and possible legal recourse.

Legal obstacle 🛑	Immediate consequence ⚠️	Recommendations from CNIL and authorities 🔎
Medical confidentiality	Blocked dissemination of information between actors	Limit exchanges to strictly necessary and anonymized data
Informed consent of insured	Obligation to obtain explicit agreement before sharing	Strengthen information and clear acceptance protocols
GDPR data protection	Risk of sanctions for non-compliance	Implementation of certified secure systems and regular audits
Legal responsibilities	Multiple recourses in case of errors	Clear definition of roles and procedures for recourse

It should be noted that these constraints are not insurmountable, and legislative proposals have been submitted to amend certain provisions, notably through facilitating joint appeals to dedicated intermediaries and establishing secure shared databases. These developments, supported by actors like Macif and Mutuelle Générale, aim to modernize the legal framework without sacrificing the protection of insured individuals, which is key to a trustworthy healthcare system.

Mutual Organizations’ Initiatives to Strengthen the Fight Against Fraud in Partnership with Health Insurance

Mutual organizations are active participants in the collective effort against fraud in Health Insurance. Some, such as Harmonie Mutuelle, Swiss Life, and MMA, play an active role by implementing innovative strategies, both preventive and repressive. Their close proximity to insured individuals gives them an advantage in early anomaly detection.

These organizations develop several action levers. One of the most structured involves centralizing and analyzing reimbursement data, notably through advanced digital tools. Using algorithms to detect inconsistencies, mutuals can flag suspect cases to Health Insurance, thus facilitating targeted controls. Simultaneously, they launch information and awareness campaigns for their members, emphasizing legal and social consequences of fraud.

• Development of digital platforms to monitor reimbursements by users.
• Creation of internal control units dedicated to fraud detection.
• Collaboration with health centers to verify the coherence of prescriptions.
• Organization of training for managers and advisors on detection techniques.
