A treating physician who refuses to extend a sick leave places the employee in a specific legal and administrative situation, with distinct avenues for contestation depending on the origin of the refusal. Understanding the difference between a refusal from the prescriber, a decision from the medical advisor of the CPAM, and a refusal for compensation by the fund itself conditions the choice of the appropriate appeal.
Medical expertise and follow-up visit: contesting the clinical basis of the refusal
The refusal to extend is based on a clinical assessment. The treating physician believes that the patient’s health condition no longer justifies the leave. This assessment is not an administrative act; it is a medical act. The patient cannot “force” their doctor to prescribe.

In this case, we recommend seeking a second medical opinion from another qualified practitioner. A general practitioner, a specialist, or a hospital doctor can prescribe an extension, provided that the initial leave was established by a physician authorized to practice in France. An extension by a doctor different from the initial prescriber remains possible, even if the CPAM may subsequently subject it to enhanced scrutiny.
If the pathology falls under a specialty (psychiatry, rheumatology, surgery), the specialist following the patient has a higher clinical legitimacy to justify the extension. Situations where it is relevant to consult another doctor include recourse in case of refusal to extend sick leave related to a disagreement on the duration of convalescence or the actual functional capacity of the employee.

Refusal from the CPAM medical advisor: the medical expertise procedure
The most common case in practice does not concern the treating physician but the medical advisor of Social Security. This advisor can notify that the leave is no longer medically justified, even if the treating physician has prescribed an extension. This notification leads to the suspension of daily allowances.

In the face of this decision, the employee has a specific recourse: request a medical expertise within ten days following the notification. This request is made to the primary health insurance fund. An expert physician, designated by mutual agreement between the treating physician and the medical advisor (or, failing that, by the director of the CPAM), then conducts an examination.
The expert’s opinion is binding on both parties. If the expert confirms that the leave is justified, the daily allowances resume. If the expert validates the position of the medical advisor, the employee loses their rights to compensation for the contested period.
- The request for expertise must be made in writing, ideally by registered mail with acknowledgment of receipt, within the strict deadline of ten days
- The treating physician must provide a detailed medical certificate supporting the need for the extension
- The employee does not have to advance the costs of the expertise, as it is covered by the fund
Amicable appeal commission and judicial court: contentious avenues
The CRA is the mandatory prerequisite before any judicial litigation. If the CPAM refuses to compensate for a leave or its extension (for non-compliance with sending deadlines, contestation of the medically justified nature, or any other administrative reason), the employee must refer the matter to the amicable appeal commission of their fund.
The referral to the CRA is made by motivated letter, attaching all medical documents and the notification of refusal. The commission generally has two months to rule. The absence of a response within this timeframe constitutes an implicit rejection.
In the event of an unfavorable decision from the CRA, the employee can bring the case before the social division of the judicial court. This appeal allows contesting both the medical basis and the administrative reasons for the refusal. We observe that producing a structured medical file, including specialist reports and results of additional examinations, significantly influences the outcome of the litigation.
Impact of refusal to extend on employer salary maintenance
An often-overlooked angle concerns the salary supplement paid by the employer. The legal (or contractual, depending on the applicable collective agreement) salary maintenance is conditioned on the coverage of the leave by Social Security. If the CPAM stops compensating, the employer can legitimately suspend the supplement.
The employee then finds themselves without daily allowances and without salary maintenance, sometimes overnight. This double financial loss further justifies the urgency of contestation.
A technical point deserves attention: the calculation of seniority granting the right to salary maintenance can lead to errors on the part of the employer. If previous sick absences are incorrectly counted in the calculation, the employee can contest the refusal of the supplement before the labor court, independently of the CPAM appeal.
- Check that the employer is correctly applying the provisions of the collective agreement (some provide for more favorable maintenance than the legal minimum)
- Keep all pay slips and notifications from the CPAM as evidence
- In case of doubt about the calculation, request a detailed breakdown from the HR department before initiating a formal contestation

The deadline for sending the extension remains a frequent trap. A late submission to the CPAM may be sufficient to justify a refusal of compensation, even if the leave is medically justified. The employee must send the portion intended for the fund within the regulatory deadlines, or risk losing their rights for the concerned period, without this loss being related to their health condition.
The distinction between medical refusal and administrative refusal determines the contestation strategy. A refusal based on clinical assessment is contested through medical expertise. A refusal linked to a procedural flaw (deadline, incomplete form, unauthorized prescriber) goes through the complaint and then the CRA. Confusing the two avenues wastes time that, in terms of daily allowances, directly translates into loss of income.
