What Is an AME or QME in California Workers' Comp?

What does an AME do?

An AME is one doctor both sides agree to use for a medical-legal opinion in a disputed workers' comp case.

An AME is chosen by agreement. The worker's attorney and the defense attorney decide to use the same doctor. The doctor reviews medical records, examines the worker, and writes a report that answers disputed medical questions.

The AME can address causation, MMI, impairment, permanent work restrictions, future care, and apportionment. The AME may also answer follow-up questions in a supplemental report or deposition.

Because both sides agreed to the doctor, an AME report can carry strong practical weight. That is useful when the AME is fair and careful. It is risky when the choice was made without enough thought.

What does a QME do?

A QME is a state-certified evaluator selected through a panel process when the parties have a medical dispute.

A QME is selected from a state-issued panel. Labor Code 4062.2 governs the represented-worker process. The panel usually has doctors in a chosen specialty. Each side may strike one doctor, leaving the evaluator who will examine the worker.

The QME is not a treating doctor. The QME writes a medical-legal report for the case. The report can decide whether an injury is work-related, whether the worker reached MMI, how impairment should be rated, and whether some disability is apportioned to non-work causes.

Specialty selection matters. Orthopedic, pain medicine, psychiatry, internal medicine, and other specialties can produce different records for different injuries. The panel should fit the actual dispute.

When do you need an AME or QME?

You usually need an evaluator when the treating doctor's opinion is disputed and benefits depend on a medical-legal answer.

A medical dispute can start early or late. Early disputes may involve whether the injury happened at work. Later disputes often involve MMI, permanent disability, apportionment, work restrictions, or future care.

The evaluator report can affect many benefits.

A QME or AME is also common when the carrier denies a body part. For example, a worker may have an accepted back claim but disputed leg symptoms. The evaluator may decide whether the leg symptoms are part of the industrial injury.

How should you prepare for the evaluation?

Prepare by reviewing your timeline, treatment history, actual job duties, current symptoms, prior injuries, and work limits.

Tell the truth plainly. Do not exaggerate. Do not minimize. The evaluator is looking for consistency between your history, exam, records, and job facts. A clear timeline helps.

Know the difference between symptoms and limits. Symptoms are what you feel. Limits are what you cannot safely do at work or home. Both matter, but they are not the same.

Make sure the record includes key medical documents. Surgery reports, imaging, therapy notes, medication records, and prior injury records can all matter. Missing records can lead to an incomplete report.

What happens after the report arrives?

After the report arrives, the parties review rating, work status, future care, apportionment, and whether a supplemental report is needed.

The report is not always the final word. It may need correction. It may miss facts. It may ask for more records. It may give an apportionment opinion that lacks a clear how and why.

A worker can seek a supplemental report when the doctor needs to answer a specific question. A deposition may be needed when the opinion is unclear or unsupported. If the report is legally defective, other remedies may be considered.

Do not accept a settlement only because a QME or AME report exists. First ask whether the report is complete, accurate, and strong enough to value the claim.

Which evaluator specialty should be used?

The evaluator specialty should match the disputed body parts, medical questions, and rating issues in the claim.

Specialty is not a detail. It can shape the entire report. A spine surgery dispute may need a different evaluator than a psyche claim, internal medicine issue, hand injury, or pain-management dispute.

The specialty should match the medical question. If the dispute is orthopedic impairment, an orthopedic panel may fit. If the dispute is psyche injury, a psychiatric evaluator may be needed. If the dispute involves multiple systems, strategy matters even more.

The wrong specialty can create a report that misses the real issue. The right specialty can make the report clearer, more useful, and easier to rate. That choice should be made before the panel request or AME agreement is locked in.

What records should be sent to the evaluator?

Important records include treatment notes, imaging, surgery reports, job-duty evidence, prior records, and benefit notices tied to the disputed issue.

The evaluator can only work from the record provided and the exam findings. Missing records can hurt the worker. Prior records can help when they show the worker was doing the job before the injury. Job records can help when the report must address actual work demands.

The records should be organized around the dispute. If MMI is disputed, the evaluator needs treatment history and current symptoms. If apportionment is disputed, prior records and work history matter. If future care is disputed, the evaluator needs treatment recommendations and response to care.
