Red Flags in IME Reports: A Guide for Attorneys
How to spot a weak IME report before opposing counsel does it for you.
The IME report arrives. The opinion is helpful. You file it, attach it to your motion, and move on. Then at deposition, plaintiff's counsel asks the examiner five questions you did not expect and the opinion starts to look very different than it did on paper.
Reading an IME report critically before you rely on it is a skill that protects your case and your client. This page identifies the most common warning signs in IME reports, why each one creates exposure, and what you should do when you find them.
Red Flag 1: The Examination Was Too Short
Time matters. If the cover sheet says the examination lasted 20 to 30 minutes for a complex multi-level spinal injury with neurological complaints, you should be skeptical before you read a single sentence of the findings.
A complete orthopedic examination of the cervical and lumbar spine, including range of motion, neurological testing, special tests for disc pathology, and functional assessment, takes 45 to 60 minutes for a straightforward case. Add psychological overlay, upper extremity complaints, or cognitive symptoms and you are looking at longer. Neuropsychological evaluations routinely take four to six hours.
Short examinations produce thin findings. Thin findings produce conclusory opinions. Conclusory opinions get challenged on cross. Ask the examiner at deposition to walk through every element of the examination they performed. If the time does not add up, you will know it during the answer.
What to do: Before retaining an examiner, ask what a typical examination time is for the injury type at issue. When you receive the report, check whether examination time is documented. If it is not, ask the examiner's office before deposition.
Red Flag 2: Records Reviewed Is a Single Sentence
'The undersigned reviewed voluminous medical records provided by counsel' is not a records review section. It is a description of an action without documentation of what was actually reviewed.
A properly documented records review lists each document by provider, date range, and type. The examiner should be able to say, under oath, that they reviewed the radiology report from the December MRI, the emergency department notes from the day of the accident, and the treating surgeon's pre-operative assessment. If the records list is generic, the examiner may not have reviewed the specific documents that matter to your case.
This becomes an acute problem when a key record contradicts the opinion. Plaintiff's counsel will ask whether the examiner reviewed that record. If the answer is uncertain, the opinion is weakened. If the answer is no, you have a much bigger problem.
Red Flag 3: Causation Opinion Without Explanation
The opinion section states: 'It is my opinion, within a reasonable degree of medical probability, that the claimant's current condition is not causally related to the alleged accident.' Full stop. No mechanism analysis. No engagement with the treating physician's contrary opinion. No reference to the medical literature. No explanation of why the pre-existing pathology accounts for the current symptoms.
Bare conclusions are targets. An opposing expert who can articulate their causation reasoning in specific medical and scientific terms will appear more credible to a jury than an examiner who can only say 'in my opinion.' Courts under Sargon and its federal equivalent Daubert look for the reasoning behind the conclusion, not just the conclusion itself.
The fix is not a longer report. It is an explanation that addresses mechanism, biology, temporality, and the specific evidence supporting the opinion.
Red Flag 4: The Report Ignores Inconvenient Records
An IME report that does not acknowledge contrary evidence is not an opinion -- it is advocacy. Experienced opposing counsel will identify every record the examiner ignored and use each one to suggest that the examiner was not objective.
The treating physician documented severe pain and functional limitation at every visit for two years. The examiner's report does not mention the treating physician at all. The pre-accident imaging showed mild degenerative changes. The post-accident imaging showed a new disc herniation at the same level. The examiner's report notes the degenerative changes but not the new herniation.
A legitimate IME report engages with contrary evidence and explains why it does not alter the conclusion. That is what makes the opinion defensible. Silence on contrary evidence is not a neutral position. It is a vulnerability.
Red Flag 5: AMA Guides Applied Incorrectly
In California workers' compensation, impairment must be rated under the AMA Guides to the Evaluation of Permanent Impairment, 5th Edition using the California PDRS. Errors in AMA Guides application are more common than most attorneys realize, and they are not always obvious to non-physicians.
Common errors include: using range of motion values that exceed the maximum allowed under the Guides without notation, applying the wrong DRE (Diagnosis-Related Estimate) category, failing to rate all impaired body systems, and arithmetic errors in calculating the combined whole person impairment. The WCAB will not overlook these errors. A report with calculation errors can be sent back for supplemental evaluation, which costs time and may produce an opinion less favorable than the original.
If you are not confident in your ability to evaluate AMA Guides application, have a second physician review the rating before submitting the report. We can review ratings for methodology and accuracy.
Red Flag 6: Waddell Signs Misused
Waddell signs are five physical examination findings described by Dr. Gordon Waddell in 1980 to identify patients who may have psychological contributions to their pain presentation. They were never designed as a malingering test. The original literature explicitly states that finding two or more positive signs does not mean a patient is fabricating symptoms.
Yet IME reports routinely cite positive Waddell signs as evidence of malingering, exaggeration, or fabrication. If the report in your case makes that connection, it is factually wrong, and it is exactly the kind of error that gives a well-prepared plaintiff's attorney a field day at deposition.
The correct use of Waddell signs is to flag a possible psychological component that warrants further evaluation, not to conclude that the claimant is dishonest. An examiner who misapplies this finding is vulnerable, and if your case depends on a finding of malingering, you need an examiner who will support it correctly, with validated symptom validity testing rather than a misused clinical sign.
Red Flag 7: The Examiner Has Never Testified
A report from a physician who has never been deposed or testified at trial is a different risk profile than one from an examiner with hundreds of depositions on the record. Litigation is a skill separate from medicine. An examiner who is outstanding clinically but has no experience under aggressive cross-examination can come apart in ways that cannot be predicted from the report.
This is not a reason to refuse to retain an inexperienced examiner. It is a reason to prepare more thoroughly, to ask the examiner to review the areas of likely attack before deposition, and to understand what you are taking on.
Red Flag 8: Opinions Outside the Examiner's Expertise
An orthopedic surgeon who offers opinions on the psychological contributions to a pain disorder, or a psychiatrist who rates orthopedic impairment, is operating outside their lane. Courts can strike expert opinions that fall outside the witness's demonstrated expertise. More practically, these opinions tend to be the least well-supported in the report and the easiest to challenge.
The solution is scope discipline: the report should address what the examiner is qualified to address, and acknowledge the need for specialist evaluation on questions outside that scope.
