Fees of doctors "conventionné honoraires libres" also called "Conventionné Secteur 2" are not fixed, i.e. doctors can charge higher fees than the official rates agreed by the Health Insurance system.
The difference between the agreed fixed rates and what you pay can be reimbursed partially or fully by complementary health insurances. You need to contact your insurance company for more information.
Dr Marie Noëlle MENARD’s fees are available on the official French Healthcare system website : ameli.fr
