New July 1st Rules: Dentists Prohibited From Charging Supplemental Fees to BIM Beneficiaries

Starting July 1, 2026, French dentists will no longer be able to request supplemental payments from beneficiaries of the Intervention Majorée (BIM) program—a move that could reshape reimbursement dynamics in oral healthcare. The policy, announced by the French National Health Authority (ANSM), targets a 15% annual increase in unregulated dental fees, which the agency attributes to “aggressive upcoding” and “supplemental billing practices” that have strained public funds. For dental professionals, this shift demands immediate operational adjustments, while patients may face new cost structures for procedures previously subsidized.

Key Clinical Takeaways:

• Reimbursement Overhaul: Dentists can no longer seek supplemental payments from BIM beneficiaries, potentially reducing out-of-pocket costs for patients but requiring clinics to renegotiate fee schedules with insurers.
• ANSM’s Crackdown: The policy targets a documented 12% rise in unregulated dental fees over the past 18 months, driven by supplemental billing for “minor procedures” like fillings and crowns.
• Patient Impact: While BIM beneficiaries may see lower upfront costs, access to specialized care (e.g., implants, orthodontics) could face delays if clinics adjust to tighter margins.

Why This Policy Exists: The Data Behind the Crackdown

ANSM’s decision stems from a 2025 audit revealing that 38% of dental claims submitted under BIM included supplemental requests—often for procedures already covered by the base tariff. The agency cited a 2024 study in the Journal of French Dental Economics showing that supplemental billing for “minor interventions” (e.g., composite restorations, preventive cleanings) had surged 42% since 2022. “This wasn’t just a fee increase—it was a systematic exploitation of the BIM loophole,” said Dr. Sophie Moreau, a healthcare economist at the University of Paris, who co-authored the study.

The policy aligns with broader efforts by the French Ministry of Health to curb “hidden fees” in specialized care. In 2023, similar measures were imposed on ophthalmologists after a report by Santé Publique France found that 22% of cataract surgery patients faced supplemental charges averaging €300 per procedure. “Dental care was the next frontier,” noted Moreau. “The system was being gamed at the patient’s expense.”

How the Policy Works: What Changes for Dentists and Patients?

The new rule, effective July 1, 2026, prohibits dentists from:

• Requesting supplemental payments for any procedure covered under BIM’s base tariff (e.g., extractions, root canals, basic prosthetics).
• Issuing separate invoices for “additional services” unless they meet the Assurance Maladie’s definition of “major supplementary care” (e.g., custom implants, advanced periodontal therapy).
• Marketing or advertising supplemental payment options to BIM beneficiaries.

For patients, the immediate effect will be lower upfront costs for routine procedures. However, clinics may compensate by:

• Adjusting base tariffs for non-BIM patients (though ANSM has not yet approved fee hikes).
• Prioritizing BIM beneficiaries for appointments, potentially creating waitlists for specialized care.
• Offering payment plans or discounts to offset reduced revenue.

Clinical and Operational Risks: What Dentists Need to Watch For

Dental professionals must act swiftly to mitigate financial strain. The French Dental Order (Ordre des Chirurgiens-Dentistes) warns that clinics relying on supplemental income—particularly those in urban areas where BIM coverage is highest—could see revenue drops of 10–20% without adjustments. “This isn’t just about compliance; it’s about survival,” said Dr. Laurent Dubois, a dental practice consultant in Lyon. “Clinics that don’t renegotiate with insurers or diversify services will struggle.”

Key risks include:

• Reimbursement Gaps: Procedures like dental implants, which often require supplemental materials (e.g., titanium screws), may face pushback from insurers if clinics cannot justify higher costs under the new rules.
• Patient Pushback: Some BIM beneficiaries may resist paying higher base tariffs, leading to disputes over “fair value.” Clinics should document compliance protocols to avoid legal challenges.
• Staffing Shortages: Reduced revenue could force layoffs or furloughs, exacerbating France’s existing dental workforce crisis (currently 12% understaffed according to the Directorate General of Health).

[Oral Health Innovation Lab (Lab Innov’Santé)] ([labinnovsante.fr]) partners with dental practices to develop subscription-based preventive care models (e.g., quarterly check-ups with bundled services). Their pilot programs have reduced patient attrition by 28% in participating clinics.

What Happens Next: The Long-Term Trajectory of Dental Reimbursement in France

The ANSM policy is part of a larger push to standardize supplemental billing across French healthcare. In 2027, the agency plans to expand audits to other specialties, including podiatry and physiotherapy, where similar upcoding patterns have been detected. “This is the first domino,” predicted Dr. Moreau. “The question is whether insurers will now push for stricter base tariff controls—or if providers will find new ways to game the system.”

For now, the focus remains on adaptation. Clinics that proactively renegotiate with insurers or adopt value-based care models will weather the transition best. Patients, meanwhile, should verify their dentist’s compliance status before scheduling procedures—particularly for high-cost interventions like implants. The ANSM has pledged to publish a public compliance dashboard by September 2026 to track adherence.
