The Workers' Comp Doctor Deposition: Why Attorneys Depose a QME and How to Testify Well
Short answer: an attorney deposes a QME to test the report against the records, to lock the physician into positions, and to find the facts the report got wrong or left out. The deposition is testimony under oath, it becomes evidence alongside the report, and a physician whose answers diverge from the report has damaged both. The physician is paid under the medical-legal fee schedule at $455 per hour with a two-hour minimum, and communications with the deposing attorney before the deposition are limited by the ex parte rules of Labor Code section 4062.3. The preparation that matters is the same as the preparation that produced a good report: knowing what is in the records and on which page.
The Saturday morning session at the 2026 CSIMS MedLaw Conference, "Standing Up to Scrutiny: Practical Deposition Strategies from Attorneys," offered evaluators a look at why attorneys take depositions and what they are trying to achieve (conference agenda). Most of the guidance available online about workers' comp depositions is written for the injured worker being deposed. This post is for the physician.
What is a deposition for a doctor?
Sworn testimony taken outside of court, recorded by a court reporter, in which the attorney for one party questions the physician and the attorney for the other party may cross-examine. In California workers' compensation, Labor Code section 5710 provides for depositions in proceedings before the Appeals Board under the procedures used in civil actions. The transcript is evidence. A judge who reads a QME report and the deposition of its author weighs them together, and an inconsistency between them is a defect in the physician's evidence as a whole.
Why do attorneys depose a QME?
Because the report is the evidence, and a deposition is the only way to test it before trial. The reasons cluster into a few goals.
To find the records the physician did not see. The deposing attorney has the production and knows what is in it. The first substantive line of questioning is often "Doctor, did you review the records of Dr. X?" and the attorney already knows the answer. A physician who wrote "no prior back complaints" and did not see the 2018 chiropractic notes at page 340 will be walked through them, and the report's history will be impeached on the record. In a spine case that is usually the degenerative apportionment falling apart. The medical record review post covers reading a production so this does not happen.
To test the reasoning. An AI-assisted chronology is fair game here too: the attorney may ask what the tool produced and what the physician verified. For each contested opinion, the attorney will ask what it rests on. An apportionment percentage without a stated basis in the report will be asked for its basis at deposition, and an answer that was not in the report invites the follow-up: why not? The judges' redline post lists the defects that generate these questions.
To obtain concessions. A well-run deposition moves through a series of small agreements, each reasonable on its own, toward a conclusion the physician would not have accepted if asked directly. "You would agree that degenerative changes of that grade can produce symptoms without trauma? And the examinee is 54? And you did not have the prior MRI?" The physician who understands where the questions are going can answer each honestly and still explain why the conclusion does not follow.
To lock in positions. Once the physician has testified under oath, the opinion cannot shift without explanation. Attorneys depose evaluators whose opinions they like as well as ones they dislike, to fix the favorable testimony before trial.
To assess the witness. Some fraction of every deposition is the attorney deciding whether the physician will be persuasive at trial and whether to settle.
What is the physician paid for a deposition?
Under the 2021 medical-legal fee schedule at 8 CCR section 9795, medical-legal testimony is billed under code ML-204 at $455 per hour, rounded to the nearest quarter hour. The physician is paid a minimum of two hours for a deposition. If the deposition is canceled fewer than eight calendar days before the scheduled date, the physician is paid a minimum of one hour. Preparation time is included in the testimony billing under the schedule's terms, and physicians should review the current text of section 9795 for the treatment of preparation, travel, and reports of the deposition, which the schedule addresses specifically. The medical-legal fee discussion elsewhere on this site covers the evaluation codes.
Can the attorney talk to the QME before the deposition?
Within limits. Labor Code section 4062.3 prohibits ex parte communication between a party and a panel QME or AME on the merits. Communications about scheduling and logistics are permitted. A substantive pre-deposition conversation between one side's attorney and the evaluator, without the other side, is the kind of contact the section is written to prevent, and an evaluator who is asked for one should decline and say why. The safe rule is that anything about the substance of the opinion goes through a communication served on both parties, and the deposition itself is where the questions get asked.
How should a physician prepare?
Reread the report, then reread the records the report relied on, then look at what the production contains that the report did not cite. The third step is the one physicians skip and attorneys count on.
Bring the records listing from the report, because the first questions will be about what was reviewed. Know the page for each fact the opinion depends on: the imaging report, the prior treatment, the examination findings. Know the Guides chapter, table, and criteria behind the impairment rating. Know the basis for each apportionment percentage well enough to state it in two sentences.
If the reread turns up something the report should have said, the honest course is to say so at the deposition when asked, and to issue a supplemental report if the omission is material. A physician who corrects the record is more credible than one who defends an error, and a judge will read the deposition either way.
How should a physician testify?
| Practice | Why |
|---|---|
| Answer the question asked, then stop | Volunteered material is cross-examination material |
| Ask for the page when a record is put to you | Testifying from memory about a document in the room is the fastest way to be wrong on the record |
| Say "I do not know" and "I do not recall" when true | Guessing under oath creates testimony that will be compared with the report |
| Distinguish possibility from probability | Medical-legal opinions require reasonable medical probability; an attorney will try to have you state a possibility and treat it as an opinion |
| Do not argue with counsel | The transcript records tone poorly and concessions well |
| Correct a prior answer as soon as you realize it was wrong | An uncorrected error becomes an impeachment exhibit |
| Take the break | There is no obligation to answer a complex hypothetical without a moment to consider it |
The hypothetical deserves its own note. Attorneys ask evaluators to assume facts and give an opinion on the assumed facts. That is a legitimate question. The answer should state that it is contingent on the assumptions, and the physician should say if the assumed facts differ from the record as reviewed.
What happens after the deposition?
The transcript is served, the physician may review and correct it under the applicable procedure, and it becomes part of the record the judge reads alongside the report. If the deposition revealed records the physician had not seen, a supplemental report addressing them is usually requested, and the report deadline post covers the timing. The case may settle on the strength of the testimony, or proceed to trial, where the deposition will be the attorney's outline for cross-examination. The after the QME report post follows the case from there.
The deposition tests one thing more than any other: whether the physician knew the production. A report built on the whole record, with every entry cited to its page, gives the attorney nothing to find and gives the physician the answer to "did you review the records of Dr. X" before the question is asked. Lexamed reads the production so the physician can say yes, and point to the page.
Frequently asked questions
Why would an attorney depose a QME? To test the report against the records, examine the reasoning behind contested opinions, obtain concessions, lock in testimony before trial, and assess the physician as a witness.
How much is a QME paid for a deposition? Under 8 CCR 9795, medical-legal testimony (ML-204) is paid at $455 per hour in quarter-hour increments, with a two-hour minimum for a deposition, and a one-hour minimum if the deposition is canceled fewer than eight calendar days in advance.
Can a QME refuse to be deposed? The evaluator is a witness in a proceeding under Labor Code 5710, and depositions are taken under the civil procedure rules. Scheduling can be negotiated; refusing is not a practical option for a QME who wants to keep the appointment.
Can one side's attorney meet with the QME before the deposition? Not on the substance. Labor Code 4062.3 prohibits ex parte communication with a panel QME or AME on the merits. Scheduling and logistics are permitted.
What is the most common problem at a QME deposition? Records the physician did not see. The deposing attorney has the production and asks about the records the report omitted, which impeaches the history and the opinions built on it.
Should a QME correct an error at deposition? Yes. Correcting a mistake when asked, and issuing a supplemental report if it is material, preserves credibility. Defending an error does not.
Does a deposition replace the report? No. The report and the deposition are both evidence, and the judge weighs them together. Testimony that diverges from the report weakens both.
