A treating physician can refuse to extend a sick leave as soon as they believe that the patient’s health condition no longer justifies it. This refusal is not an arbitrary administrative act: it is based on the clinical assessment made during the consultation. The situation places the employee in the face of a potential interruption of their daily allowances, without the pathology necessarily being resolved.
Why a doctor refuses to extend a sick leave
The refusal to extend reflects a medical judgment on the patient’s functional capacity. The doctor considers that returning to work, possibly with adjustments, is compatible with the current health status.

The recommendations from the HAS on sick leaves for anxiety-depressive disorders, updated in 2023, emphasize the limited duration of initial sick leaves and the priority for a suitable return (therapeutic part-time, job adjustments) rather than successive extensions. This framework explains why refusals are increasing, particularly for mental health issues.
When a sick leave extension is refused by the doctor, the employee must distinguish between two situations: one where their health condition genuinely allows for a return, and one where a medical disagreement remains regarding the severity of the pathology.

The pressure exerted by the CPAM controls also weighs on prescribers. Since 2023, the funds have strengthened targeted controls on long and repeated sick leaves. The medical advisor can reduce or stop daily allowances even if another practitioner agrees to extend the leave, when the medical justification is deemed insufficient.

Medical recourse after a refusal to extend sick leave
In the face of a refusal, the first option is to consult another authorized practitioner. Article L-162-4-4 of the Social Security Code strictly regulates this possibility.
Conditions for another doctor to prescribe the extension
The extension must, in principle, be prescribed by the initial prescribing doctor, the treating physician, or a midwife. Article R162-1-9-1 of the Social Security Code provides for three exceptions:
- The initial prescribing doctor or the treating physician is unavailable (absence, leave, retirement), and the patient justifies this impossibility to the CPAM
- The extension is prescribed by a specialist consulted at the request of the treating physician, within the framework of coordinated care
- The extension occurs in a hospital context (hospitalization, emergency consultation, post-operative follow-up)
Outside of these cases, an extension prescribed by a non-authorized doctor results in the loss of daily allowances. The employee risks finding themselves without replacement income for the entire duration of the unvalidated leave.
Consulting the occupational physician before returning
The law of August 2, 2021, strengthening health prevention at work, has expanded the role of the occupational physician. They can intervene through a pre-return visit to assess the compatibility between the health status and the job held. This visit may lead to recommendations for job adjustments, temporary reassignment, or therapeutic part-time work.
The pre-return does not replace the extension of sick leave. It allows for preparing a return to work under suitable conditions, which often meets the real needs of the employee when the treating physician believes that total leave is no longer justified.
Therapeutic part-time: an alternative to renewing sick leave
Therapeutic part-time often constitutes the most suitable response when the doctor refuses the extension while the employee does not feel fit to return full-time. The principle: the employee partially resumes their activity while continuing to receive daily allowances to compensate for the loss of salary related to the reduction of working hours.
To benefit from this, the agreement of the treating physician, the employer, and the CPAM is necessary. The doctor prescribes the part-time return, specifying the percentage of activity and the expected duration. The employer must accept the job adjustment.
This solution has a concrete advantage: it maintains the link with employment and social rights while respecting the physical or psychological limits of the employee. The HAS recommendations explicitly favor it for anxiety-depressive disorders, where prolonged sick leaves sometimes worsen isolation and hinder recovery.

Steps with the CPAM in case of disagreement on the return
If the disagreement persists between the employee and their treating physician, a medical assessment can be requested from the CPAM. The medical advisor of the fund then independently evaluates the health status.
The employee can request this assessment by directly contacting their fund. The medical advisor has the authority to validate or invalidate the necessity of a sick leave, regardless of the treating physician’s position. Their decision is binding for the payment of daily allowances.
In case of disagreement with the decision of the medical advisor, the employee has recourse to the amicable medical appeals commission (CMRA) of their fund. This recourse must be exercised within two months following the notification of the contested decision. The CMRA re-examines the medical file and issues an opinion that may confirm or overturn the initial position.
Protecting rights during the procedure
Throughout the duration of the recourse, the employee must pay attention to two points:
- Respect the 48-hour deadline for sending any new sick leave notice to the CPAM and the employer, under penalty of a reduction in their allowances
- Keep all medical documents (certificates, reports, prescriptions) that attest to the persistence of the pathology
- Inform the employer of their situation to avoid an unjustified absence that could lead to disciplinary action
The refusal to extend by the treating physician does not mean the end of the employee’s rights. The pre-return visit, therapeutic part-time, and recourse to the medical advisor offer concrete levers. The choice between these options depends on the pathology, the job held, and the relationship with the employer, three parameters that only an in-depth medical exchange can clarify.
