Experts warn about the risks of 100% health coverage in optics and hearing aids

Since the widespread implementation of the 100% Health program in optics and hearing aids, several expert voices have raised alarms about concerning deviations that undermine the initial objectives of this reform. Designed to ensure comprehensive coverage without out-of-pocket costs for patients, especially in the areas of visual health and auditory health, this measure, though praised, continues to face numerous challenges. Its complexity raises questions about the quality of care, commercial practices, and the long-term financial sustainability of the system.

Within this context, several issues are pointed out: the rise of questionable practices among certain opticians and hearing aid specialists, deficiencies in information provided to patients, and mechanisms sometimes bypassed in the reimbursement of equipment such as glasses or hearing devices. Furthermore, financial pressure on complementary organizations and health insurance creates a risk of budget overruns and calls for urgent corrective measures.

This complex issue invites a detailed examination of the identified disorders, the stakes for beneficiaries, and the strategies envisioned for effective recovery. Prevention and strengthening of diagnostics related to problematic practices are essential to ensure transparency and quality of the 100% Health system in the future.

Observed Deviations in the 100% Health Program in Optics: Implications for Visual Health

The implementation of 100% health in optics aimed to offer patients glasses fully reimbursed through so-called “responsible” equipment, without any out-of-pocket expense. While this marked a significant step forward in access to care, many malfunctions are occurring on the ground.

Reports indicate ambiguous, even unfair commercial practices by some opticians. In several stores, 100% health offers are often disparaged with terms like “basic” or “entry-level,” which negatively influences patients’ perception of the quality of the products offered. As a result, some consumers hesitate to choose the reimbursed range, preferring more expensive frames with remaining costs, despite the benefits guaranteed by law.

In addition, the lack of clear and transparent information about coverage procedures and guaranteed warranties hampers full adoption of this system. Confusion especially arises regarding product selection criteria and warranty duration, both critical for long-term visual health. The absence of an in-depth ocular health assessment before prescription leads to sometimes inappropriate adjustments of glasses, compromising comfort and optical correction.

• Devaluing the 100% health offer in the eyes of clients
• Commercial practices aimed at diverting towards non-reimbursed equipment
• Lack of transparency about guarantees and product lifespan
• Frequent absence of a full visual assessment prior to choosing glasses
• Risks of under-equipment or inappropriate equipment for some patients

Aspect	Current situation 🕶️	Impact on the patient
Information provided	Often insufficient, confusing messages	Doubt, uninformed choices
Perceived quality	Offer judged as “entry-level” in the 100% health system	Rejection of the offer, increased costs
Product adaptation	Visual control sometimes limited	Poor correction, discomfort

It should be noted that the objectives of the reform remain relevant, but highlighting these deviations requires decisive action to better regulate the practices of eye health professionals and thus ensure fair and secure access to 100% health equipment in the future.

Impacts of Deviations in 100% Health on Hearing Aids and Auditory Health

In audiology, the widespread adoption of 100% health has increased access to hearing aids. However, this breakthrough is not without difficulties, as some companies and professionals exploit the system to maximize profits, often at the expense of service quality provided to patients.

Since 2019, resetting the remaining costs on certain hearing aid models has led to a dramatic rise in sales. A sector report states a 72% increase in the market in 2021. However, this rapid growth is accompanied by a rise in questionable practices: overestimation of services, equipment not suited to diagnosis, or premature replacement of functional devices.

The lack of strict medical or audiological follow-up promotes sometimes inappropriate fitting, leading to a decline in auditory health rather than improvement. Additionally, cases of overbilling have been identified, with invoices exceeding the caps set by the system, revealing frauds that harm social security and consumers.

• Overbilling and exceeding capped tariffs
• Conflict of interests and non-targeted sales
• Insufficient or absent medical follow-up
• Inappropriate or prematurely replaced devices
• Excessive commercial pressure on patients

Factor	Situation in 2025 🎧	Consequence
Capped reimbursement	Detected fraud exceeding caps	Financial loss for social security
Post-fitting follow-up	Often limited or absent	Discontent, risks to auditory health
Quality of fitting	Significant disparities	Inappropriate fit, prolonged discomfort

In response to these findings, calls for better regulation and strengthened control procedures have been made by several expert groups to restore essential confidence. The goal of the 100% health reform—to facilitate access to hearing devices while maintaining quality—remains a key issue for the health system’s balance.

Reimbursement and coverage: a fragile balance under scrutiny

The 100% health system has radically changed the coverage of optical and auditory treatments by implementing full reimbursement for so-called essential equipment. Despite notable progress, several factors threaten this fragile balance.

On one hand, increased pressure on health insurance funds and mutual insurers raises concerns about the long-term financial viability of the measure. A recent report estimates fraud at around 50 million euros related to 100% health devices, mainly through overbilling and false billing practices.

On the other hand, the mechanisms of financial compensation between supplementary organizations and social security remain complex and sometimes opaque. These difficulties feed tensions in the reimbursement chain, to the detriment of insured individuals who face longer delays or unexpected refusals.

• Identified fraud in 100% health systems
• Sometimes excessive reimbursement delays
• Complex administrative procedures
• Tensions between health providers and supplementary insurers
• Risks of non-effective coverage for some patients

Problem	Impact	Proposed solutions
Fraud and overbilling	Additional costs for social security and insurers	Enhanced controls and increased sanctions
Extended delays	Patient dissatisfaction	Digitization of reimbursement processes
Administrative complexity	Confusion and refusals	Simplification of procedures

The financial stability of the system therefore depends on increased vigilance towards these limits, to preserve both the quality of coverage and the actual sustainability of the system. Additional reforms are being considered in this regard.

Patient communication and information: gaps and consequences

One recurring criticism of the 100% health system lies in the lack of clear or accessible information for beneficiaries. Despite an official commitment to transparency, patients are often poorly informed about their actual rights, options for choice, and procedures related to their reimbursement.

Several field surveys indicate that this lack of information fosters a natural mistrust among consumers towards the 100% health offer. Healthcare professionals, especially opticians and hearing aid specialists, may not always take the time to explain in detail the content of prescriptions and the nature of reimbursed equipment, leading to perceived opacity.

This deficit is also linked to the complexity of regulatory procedures and often technical language, difficult for the lay public to understand. The immediate consequence is underutilization of zero-out-of-pocket benefits, and sometimes choosing more costly services or equipment that lack medical justification.

• Lack of awareness among beneficiaries
• Overly complex or disparate technical information
• Poor understanding of eligibility criteria
• Absence of proactive dialogue with practitioners
• Negative impact on the use of 100% health

Observed deficit	Main cause	Impact on beneficiaries
Incomplete information	Regulatory complexity, lack of pedagogical effort	Mistrust, refusal of service
Inconsistent communication	Limited availability of professionals	Confusion in equipment choices
Lack of appropriate tools	Low investment in training	Under-utilization of the program

Decisive action on this information front is essential to restore trust, improve user experience, and strengthen the effectiveness of the 100% health system in optics and hearing aids.

Ethical and Legal Issues Related to Deviations in the 100% Health Program

Given the extent of the deviations identified, the question of ethical standards and the legal framework surrounding 100% health is at the heart of ongoing debates. In optics as well as in hearing aids, some irregularities highlight practices potentially contrary to the professional deontology principles of health practitioners.

Certain stores have been accused of maneuvering to circumvent legislation, including offers that undermine the system or encourage purchases outside the regulatory framework. The lack of sufficiently dissuasive sanctions in some cases raises concerns about normalization of misconducts.

Meanwhile, patients themselves face difficulties in defending their rights, confronted with inadequate information and burdensome administrative procedures. Consumer protection thus appears as a fundamental issue to strengthen trust and ensure equitable access to care.

• Respect for the legal and deontological framework of care
• Fight against aggressive commercial practices
• Strengthening sanctions and controls
• Patients’ rights and access to information
• Professional responsibility in case of misconduct

Legal aspect	Current situation ⚖️	Future objectives
Monitoring practices	Insufficiently rigorous	Intensified audits
Sanctions	Not sufficiently dissuasive	Increased severity
Patient information	Often incomplete	Full transparency

These challenges highlight the need for strengthened governance, combining ethics and regulation, to ensure the sustainability and robustness of the 100% health system in the years to come.
