What Happens in a California QME or AME Medical-Legal Evaluation?

Why Medical-Legal Evaluations Exist in California Workers' Compensation

Disagreements over medical questions are common in California workers' compensation claims. An injured worker's treating physician may reach conclusions about the nature of an injury, its cause, or the resulting work restrictions that the claims administrator disputes. When those disagreements cannot be resolved through the treating physician's network, California law provides a formal process for obtaining an independent medical-legal opinion. This article is general educational information, not legal advice.

The two primary mechanisms are the Qualified Medical Evaluator (QME) and the Agreed Medical Evaluator (AME). Both produce written reports that carry significant weight in resolving disputed medical issues, but they arise in different circumstances and follow different procedures. The DWC Medical Unit oversees the QME program, including physician certification and panel assignment.

It is essential to understand from the outset that neither a QME nor an AME is your treating doctor. Their role is to evaluate — not to provide ongoing care. Their findings are used to resolve specific disputed medical questions within the claims process, and their reports become part of the legal record.

QME vs. AME: Which Process Applies to Your Claim

The path to a medical-legal evaluation depends largely on whether the injured worker is represented by an attorney.

Unrepresented workers who have a medical dispute typically go through the QME panel process. The DWC randomly assigns a panel of three QME physicians in the relevant specialty. The worker and the claims administrator each have the opportunity to strike one name, and the remaining physician conducts the evaluation. QMEs are certified by the DWC and must meet specific training and continuing education requirements described on the DWC Medical Unit page.

Represented workers — those with legal counsel — and the claims administrator may mutually agree on a single physician to serve as the AME. Because both sides select the evaluator together, the AME process can sometimes move more efficiently, though agreement is not always reached. If the parties cannot agree on an AME, the QME panel process is used instead.

The DWC FAQ notes that medical disputes can involve questions such as whether the injury is work-related, the extent of permanent impairment, the need for future medical treatment, and work capacity. The specific question in dispute shapes which specialty panel is requested.

What Happens Before, During, and After the Evaluation

Preparation matters. Before the appointment, the evaluating physician typically receives a packet of records that may include prior medical records, imaging studies, the employer's description of job duties, and correspondence from the claims administrator. Both the worker and the claims administrator may submit records and written questions for the evaluator to address.

During the evaluation itself, the physician conducts a clinical interview and physical examination. The evaluator reviews the submitted records and may ask detailed questions about the history of the injury, prior conditions, and current symptoms. The appointment is not a treatment visit — the physician is gathering information to form a medical-legal opinion.

After the evaluation, the physician prepares a written report addressing the disputed issues. Strict timelines govern when the report must be completed and served on the parties. Either side may submit written objections or request a supplemental report if new medical information emerges. In some cases, a follow-up evaluation or deposition of the evaluator may occur.

Use this checklist to help prepare for a QME or AME appointment:

• Confirm the appointment date, location, and the evaluating physician's specialty in advance.
• Gather and organize all relevant medical records, including records predating the work injury that relate to the affected body part.
• Write a clear, chronological account of how the injury occurred and how your symptoms have changed over time.
• Bring a list of all current medications and any assistive devices you use.
• Understand which specific medical questions are in dispute — ask your claims administrator or attorney to clarify.
• Do not bring anyone into the examination room without prior authorization from the evaluator.
• Review the report carefully once it is issued and note any factual errors about your history or symptoms.

Important Limitations of the QME and AME Process

The QME and AME process has meaningful limitations that workers should understand. The evaluator's report is influential but not automatically final — parties may dispute the report's conclusions through the workers' compensation appeals process, and a workers' compensation judge ultimately weighs the medical evidence.

Timing rules are strict. Missing a deadline to strike a panel physician, respond to a report, or request a supplemental evaluation can affect a worker's rights. The DWC Medical Unit publishes procedural information, but the rules are technical and fact-specific.

Additionally, a QME or AME evaluation addresses only the disputed medical questions presented — it does not resolve every aspect of a claim. Separate disputes over benefit amounts, liability, or vocational issues may require additional proceedings. Workers with complex injuries, prior conditions affecting the same body part, or disputed injury dates face particularly nuanced evaluations where the report's framing of causation and apportionment can have significant downstream effects on benefits. Consulting qualified legal counsel before and after a medical-legal evaluation is worth serious consideration.
