Relationships between policyholders and health insurers can sometimes be a source of tension and disagreement, particularly due to coverage refusals, reimbursement delays, or contractual discrepancies. When a dispute arises, it’s best to know what steps to take to effectively assert your rights. Whether with recognized players such as MMA, MAAF, Macif, Groupama, Allianz, AXA, April, Generali, Swiss Life, or Mutuelle de Poitiers, problems abound, and recourse options are sometimes overlooked. Over the years, amicable and legal dispute resolution mechanisms have evolved to offer tailored solutions to policyholders. Understanding the role of these organizations, the steps to follow, as well as the possible recourses to mediation and the courts, allows you to better understand these delicate situations and act with confidence, while respecting the legal and contractual framework. In this article, explore in detail the solutions available to you, illustrated with concrete examples and practical advice for the smooth management of your health insurance dispute. How to resolve a dispute with your health insurance: amicable approach and mediation
It is essential to seek an amicable resolution for any dispute with your health insurance. This approach avoids lengthy and costly procedures. It generally begins with direct contact with your insurer’s customer service department, such as those offered by MMA or AXA. Clearly explain your problem, providing all supporting documents, such as invoices, contracts, and correspondence.
In the event of a refusal or an unsatisfactory response, a written complaint is recommended. A registered letter with acknowledgment of receipt addressed to the complaints department allows you to formalize and track your request. This letter must precisely describe the dispute, the contractual references, and your expectations. Letter templates for a
cancellation or dispute are available online to facilitate drafting. If no satisfactory response is forthcoming, contacting the mutual insurance mediator is an essential step. For example, Swiss Life or Generali provide a free mediator who acts as an impartial third party to seek a fair solution. Referral to the mediator must be made in writing, accompanied by documentation relating to the case. This is a suitable solution with a high success rate, avoiding the need for legal action.

When amicable settlements fail, recourse to the courts becomes necessary. The courts intervene to resolve disputes relating to the insurer’s failure to fulfill contractual obligations or the improper application of guarantees. In France, actions can be brought before several jurisdictions depending on the nature of the dispute:
⚖️ Judicial Court for civil disputes related to the execution of the health insurance contract
- 🛡 Administrative Court for decisions made by public bodies such as Social Security
- 📑 High Court for complex disputes or when the amount at stake is high
- In certain situations, particularly in cases of medical malpractice or unjustified refusal of coverage, criminal proceedings may be initiated. This may concern, for example, failure to report an accident, insurance contract fraud, or gross negligence on the part of a healthcare professional supported by a mutual insurance company such as April or the Mutuelle de Poitiers. Here is a list of the key steps in legal proceedings:
