In Defense of Expertise: Why QMEs and AMEs Matter More Than Ever

QME and AME Expertise matters more than ever in 2025 and 2026

In California’s workers’ compensation system, Qualified Medical Evaluators (QMEs) and Agreed Medical Evaluators (AMEs) remain the foundation of fair and objective medical-legal decision-making. Their evaluations provide the evidence that judges, attorneys, and claims professionals rely on to resolve complex disputes. In recent years, however, defense arguments have increasingly sought to blur the distinction between the independent evaluations of QMEs and AMEs and the opinions of Primary Treating Physicians (PTPs). Understanding these arguments and the case law surrounding them is essential for evaluators who want to protect the authority and credibility of the QME and AME process.

One of the most common strategies used by defense is to selectively cite portions of Labor Code sections 4060 and 4064. They often highlight the sections that limit liability for certain medical-legal costs while omitting key language in section 4060 that reads, “Neither the employer nor the employee shall be liable for any comprehensive medical-legal evaluation performed by other than the treating physician, except as provided in this section.” This is sometimes used to suggest that treating physician reports are preferable or sufficient. In reality, the statutory framework and decades of legal interpretation confirm that QMEs and AMEs are the intended sources of independent medical-legal evidence once a claim becomes contested.

Recent decisions such as Rico v. Starcrest Products of California, Inc. (2023 Cal. Wrk. Comp. P.D. LEXIS 107) and Verdeja v. Target Corp. (2024 Cal. Wrk. Comp. P.D. LEXIS 296) recognize that a treating physician’s report may occasionally serve a dual purpose in denied claims. However, these are limited exceptions that do not replace or diminish the role of QMEs and AMEs. Their evaluations are uniquely designed to meet the legal threshold of substantial medical evidence and to comply with procedural requirements such as timeliness extensions under Labor Code 4062.5 and notice standards set out in California Code of Regulations section 9793(h). These procedural safeguards exist to protect both parties and uphold the neutrality that defines the QME and AME process.

Case law further supports that the use of a treating physician for a medical-legal evaluation does not preclude or override the authority of a QME or AME. In Loza v. Goldblatt/Bay Area Restaurant Management (2020 Cal. Wrk. Comp. P.D. LEXIS 361) and Warren Brower v. David Jones Construction (ADJ802221), the Appeals Board made it clear that both types of evaluations can coexist, even within the same specialty. Nevertheless, the opinions of QMEs and AMEs continue to hold greater evidentiary weight because they are conducted under stricter legal and procedural standards.

For evaluators, maintaining strict adherence to these standards is not just a matter of compliance but a matter of professional integrity. Every timely report, properly issued notice, and accurate billing record reinforces the legitimacy of the QME and AME system. While defense arguments may continue to evolve, the purpose of the QME and AME framework remains the same: to provide unbiased, well-documented, and legally sound evaluations that form the foundation of fair decision-making in California’s workers’ compensation system.

Ultimately, protecting the QME and AME process means preserving the highest standards of medical-legal practice. The independence and expertise of these evaluators ensure that the system remains rooted in truth, clarity, and fairness. Their role is irreplaceable, and their commitment to both medical accuracy and legal compliance is what keeps the workers’ compensation system balanced and just for all parties involved.
