The control physician is a practitioner assigned by an employer or a private insurer to verify the medical justification for a work stoppage. Their intervention is limited to assessing the employee’s ability to return to their position, without providing a diagnosis that can be communicated to the company. This functional distinction, often misunderstood, is crucial for the legal validity of any follow-up visit.
Control Physician and CPAM Medical Advisor: Two Distinct Functions
The confusion between these two medical figures arises in the majority of disputes related to sick leave. The medical advisor is employed by the Primary Health Insurance Fund (CPAM). They operate within a public service framework and can directly influence the payment of daily allowances, or even decide to suspend them.

The control physician, on the other hand, intervenes at the request of the employer or a private insurer. Their opinion does not bind the CPAM. They write a report that only addresses the consistency between the observed health status and the duration of the prescribed leave. The employer can then decide to suspend the salary supplement, but not the daily allowances paid by Social Security.

The CPAM medical advisor can also summon an insured person for a medical examination independent of any employer request. These two controls can overlap without replacing each other, which sometimes generates contradictory conclusions regarding the same leave.

Legal Obligations of the Control Physician During a Follow-Up Visit
The employer’s follow-up visit follows specific rules. The employee on leave must be present at their home during the hours of prohibition set by the treating physician, except in cases of authorized outings noted on the leave certificate.
The control physician visits the employee’s home or summons them to their office. Several obligations govern their intervention:
- They must disclose their identity and their role as a control physician mandated by the employer before any examination.
- They cannot communicate any diagnosis or personal medical data to the company. Their report is limited to an opinion on the justification of the leave.
- They must respect the principle of contradiction: the employee can refuse the examination, but this refusal may lead to the suspension of the employer’s supplement.
- They cannot modify the prescription of the treating physician or shorten the duration of the leave concerning the CPAM.
Medical confidentiality remains enforceable against the employer, even if the employer finances the follow-up visit. Recent case law has reinforced this obligation, limiting the content of the report to a binary conclusion: justified leave or not justified.
Traceability and Evidentiary Value of Employer Medical Control
A poorly formalized follow-up visit report loses all utility in front of labor courts. Companies, especially in Paris where social litigation is dense, increasingly resort to outsourced follow-up visit services with enhanced written traceability.
This evolution responds to a concrete need. When an employer suspends the salary supplement based on a control physician’s opinion, the employee can contest this decision. The report must then constitute an enforceable document, time-stamped, specifying the conditions of the visit, the identity of the practitioner, and the reasoned conclusion.
What the Report Must Contain
The document sent to the employer mentions the date and time of the visit, the presence or absence of the employee, and the conclusion regarding the medical justification of the leave. No clinical elements are included. An incomplete report weakens the decision to suspend the salary supplement and exposes the employer to a risk of labor court disputes.
The control physician also maintains a confidential medical file, subject to the same conservation rules as any patient file.

Public Sector and Private Sector: Different Control Objectives
In the territorial or hospital public service, medical control does not pursue the same objective. It is part of a statutory framework that conditions the maintenance of salary (equivalent to wages) and the possible placement in compulsory leave.
The accredited physician, requested by the administration, assesses the employee’s ability to resume their duties. Their opinion can trigger a referral to the medical committee for long-term sick leave or long-term leave. Control in the public sector aims at statutory fitness, not just the justification of a leave.
In the private sector, the goal remains to verify the consistency between the declared health status and absence from the position. The employer has no power over the daily allowances from Social Security, and the control physician never replaces the CPAM medical advisor.
This difference in legal framework explains why the same term, “medical control,” encompasses procedures, actors, and consequences that are very different depending on whether the employee falls under private law or public service status. Precisely identifying the applicable regime before any dispute remains the first step to exercising one’s rights or securing an employer’s decision.
