Where a Qualified Medical Evaluator (QME) is selected from a panel of three doctors assigned by the Division of Workers' Compensation, an Agreed Medical Evaluator (AME) is jointly chosen and agreed upon by the professionals managing an employer's defense and the attorney representing an injured employee.

Both evaluator types are impartial physicians expected to assess an injured employee, review medical records, and opine on the issues in question. Understanding the difference between them and knowing when each pathway serves a case best, is important for every party in a California workers' compensation claim.

How an AME Works in California

Several foundational rules govern the AME process:

• An AME can only be used if the injured employee has legal representation. Unrepresented workers must use the QME panel.
• The physician must be selected by mutual agreement between the injured worker's attorney and the adjuster or defense attorney. Neither party can unilaterally impose an AME.
• An AME can be a Qualified Medical Examiner but is not required to hold DWC QME certification when functioning in an agreed capacity, which broadens the available physician pool.
• Not every physician agrees to function as an AME. Knowing which physicians are willing, available, and experienced in med-legal evaluation is where a knowledgeable evaluation partner adds real value.

Importantly, an AME report carries greater evidentiary weight than a standard PQME report at the Workers' Compensation Appeals Board. Because both parties agreed on the physician, the WCAB affords the AME's opinion heightened credibility, making physician selection a decision with direct impact on case outcomes.

The QME Wait Time Problem

Many choose an AME to avoid the lengthy wait times of the state's randomized QME panel process. Due to heightened requests, physician shortages in certain locations and specialties, in addition to the risk of panel application rejection, the QME process can consume four to five months from panel issuance to report receipt. It takes 90 to 120 days just to schedule the evaluation, plus 30 days for the physician to complete and serve the report.

Compounding this, there are sixteen separate grounds under California Code of Regulations Section 31.5 on which a replacement panel may be requested. These include physician unavailability, specialty mismatches, and geographic conflicts. Each replacement adds weeks or months to an already extended timeline.

Once parties agree on an AME, they contact the physician's office directly to schedule. No panel, no waiting, no replacement requests, just a scheduled appointment and a clear path toward answering the outstanding case questions.

Faster answers benefit every party. For injured workers, that means timelier access to appropriate care. This also results in faster claim resolution. Having a specialist review records, evaluate the injured employee, and answer questions provides clarity for treatment as well as disability.

Control, Credibility, and Case Resolution

With the QME panel process, the DWC generates a random list of three physicians. The parties must work within that pool. With an AME, both sides have direct input into selecting a physician whose qualifications and med-legal experience match the case's complexity.

That shared vetting process aligns incentives. Both sides are more likely to accept a well-reasoned opinion from a physician they each helped select, which translates to fewer disputes over methodology, fewer depositions, and a faster path to providing the injured employee necessary benefits while moving toward settlement.

The AME's opinion also drives the most consequential numbers in a case, the permanent disability rating and apportionment analysis. Under Labor Code Section 4663, apportionment determines what portion of a claimant's disability is attributed to industrial versus non-industrial causes, directly affecting claim value. A credible, well-supported, unbiased AME opinion is one of the most effective tools for reaching appropriate case resolution on both sides.
