In France, doctors are divided into two sectors based on how they charge for their services. Sector 1 doctors charge fees set by the Social Security system, ensuring that most of the cost is covered by health insurance. Sector 2 doctors, on the other hand, can charge additional fees beyond the standard rate. These extra charges can significantly increase the cost of a medical visit. For example, a consultation with a sector 2 specialist might cost 90 euros, while a similar visit with a sector 1 doctor would be around 31.50 euros. Even with a good supplementary health insurance plan, patients may still face a higher out-of-pocket cost when visiting a sector 2 doctor. Visiting a sector 1 doctor typically means that 70% of the consultation cost is covered by the Social Security Health Insurance, with the remaining amount often reimbursed by supplementary insurance. However, patients still pay a flat rate of 2 euros. The downside of sector 1 doctors is that they are often in high demand, making it challenging to secure an appointment. Therefore, it's advisable for patients to plan ahead and book appointments in advance. A doctor charging additional fees is not necessarily doing so for profit. These fees may be necessary to cover general expenses or may result from a lower reimbursement base. To keep costs down, it's recommended to follow the care pathway by consulting a specialist only on the recommendation of a general practitioner, who provides a referral letter. Exceptions to this include specialists like ophthalmologists, psychiatrists, or gynecologists, who are often accessible without a referral. To check if a doctor is in sector 1, patients can consult the health directory on Ameli.fr, the official website of the French Social Security. The doctor's profile will indicate whether they are in sector 1 or sector 2, along with their fees when available. If the note "no additional fees" appears, it confirms the doctor is in sector 1. Alternatively, patients can contact the medical secretary directly to confirm whether any additional fees might apply. For medical procedures or consultations with fees reaching 70 euros, a written estimate or quote must be provided to the patient before the service is performed, unless it's an emergency. Additionally, the fees should be displayed in the waiting room for transparency. Some sector 2 doctors are affiliated with Optam, an organization that commits them to limiting their additional fees and performing part of their services at the conventional rate. While the Optam label does not guarantee no additional fees, it allows for better control and more favorable reimbursement rates for patients. This information is available on Ameli.fr, in contrast to the "free fees" category. In cases where additional fees are involved, the amount covered by supplementary health insurance varies depending on the contract. For example, with a 150% guarantee, reimbursements from both the Social Security and the mutual insurance can reach up to 150% of the base rate covered by the Social Security, not 150% of the total bill. If a dermatologist in sector 2 Optam charges 90 euros for a consultation, the base reimbursement rate remains at 31.50 euros. The Social Security would cover 20.05 euros after subtracting the 2 euro flat rate, and the mutual insurance would cover 9.45 euros at 100% of the base. This leaves the patient with an out-of-pocket cost of 60.50 euros. These additional fees can quickly lead to a significant increase in a patient's health-related expenses, making it crucial to be aware of these costs.
