Cross Examining an IME Physician: Tactical Guide for Attorneys

The Independent Medical Examination (IME) is pivotal evidence in personal injury, workers’ compensation, and disability litigation. An IME report can shift case valuations by six figures or determine survival at summary judgment.

But every experienced litigator knows: the label “independent” can be misleading. The physician, chosen and paid by the opposing side, generates a report intended to be used against your client.

Cross-examining that physician effectively is not about medical knowledge. It is about preparation, pattern recognition, and exposing the gap between what the report claims and what actually happened in the exam room.

The IME Physician Is Not Your Client’s Doctor

Before you draft a single question, understand the structural dynamic at play. An IME physician does not have a treatment relationship with the examinee. The American Medical Association’s Code of Medical Ethics recognizes that IMEs create a “limited patient-physician relationship,” one that exists for evaluation, not care.

This distinction matters because it frames every question you will ask. The IME physician:

• Spent minutes, not months, with your client
• Reviewed a file assembled by the defense, not a complete medical history
• Has no follow-up obligation, no duty to treat, and no ongoing relationship
• Is paid for their opinion, not their care

Each of these facts is a door you can walk through during cross-examination.

Phase One: Know the Report Cold

Before you depose or cross-examine an IME physician, you need to live inside their report. Read it alongside every other medical record in the case. Create a comparison grid:

Look for what is missing. IME physicians frequently omit or minimize:

• Diagnostic imaging that supports the injury claim
• Treating physician notes that contradict their conclusions
• The full duration and consistency of the plaintiff’s complaints
• Functional limitations documented by physical therapists or specialists

   

Every omission is a cross-examination opportunity. If you are working with an IME provider that conducts rigorous quality assurance reviews, you will see reports with clearly separated objective findings and documented methodology, making them harder to attack. Poor-quality reports, by contrast, blur observation and opinion into a single, conclusory paragraph.

Phase Two: Attack the Financial Bias

The single most effective line of cross-examination in most IME cases targets the physician’s financial relationship with the defense. Juries understand incentives.

Start with the basics:

• How much are you being paid for today’s testimony?
• How much did you charge for the IME itself?
• How much for the records review?
• How much for the deposition?
• What percentage of your annual income comes from IME work, as opposed to treating patients?

The numbers often tell a story on their own. A physician earning $400,000 per year from IME work, performing 15–20 exams per month for insurance carriers and defense firms, is not independent in any meaningful sense. They are professional witnesses.

Ask how many times they have testified for plaintiffs versus defendants. Most career IME physicians have a 90%+ defense retention rate. When the witness has to concede they have not been retained by a plaintiff in five years, the jury takes notice.

If you are an attorney hiring an IME physician for your own case, this is why vetting matters. Providers like MLP IME screen physicians through credential verification systems, including SAM.gov and the OIG exclusion database, and maintain panels of board-certified physicians whose credibility holds up under scrutiny. An expert with balanced experience on both sides of the aisle is harder to dismiss as a hired gun.

Phase Three: Challenge the Methodology

After financial bias, turn to what the physician actually did or did not do during the examination.

How Long Was the Exam?

IME exams are notoriously brief. A treating orthopedic surgeon may spend 30 minutes with a patient; an IME physician may spend eight. If the report does not state the exam duration, ask. When the answer comes back as 10 or 12 minutes, contrast it with the years your client has spent under the care of treating physicians.

What Tests Were Performed and What Was Skipped?

An IME for a spinal injury should include range-of-motion testing, neurological assessment, and review of imaging. Ask:

• Did you perform a Spurling test? A straight leg raise test?
• Did you measure the range of motion with a goniometer or estimate visually?
• Did you review the actual MRI films, or only the radiologist’s report?
• What diagnostic tests did you perform that the treating physician did not?

Physicians who skip standard objective tests and then opine that there is “no objective evidence of injury” are vulnerable. The contradiction writes itself.

Did They Review the Complete Record?

IME physicians are often provided with a curated set of records from the defense attorney’s selection, rather than the full medical file. Establish on the record exactly what was and was not provided:

• Were you given the pre-accident medical records?
• Did you review all post-accident treatment notes, or only select visits?
• Were you provided the physical therapy records? The pain management records?
• Did anyone tell you not to review certain records?

A physician who opines without reviewing the full record is offering an opinion on incomplete data. Juries understand that.

Phase Four: Expose the Gap Between Treating and IME Physicians

The treating physician spent months or years managing your client’s care. The IME physician spent minutes. This asymmetry is the foundation of the most effective cross-examinations.

Frame the comparison explicitly:

• “Dr. Smith, the treating orthopedic surgeon, has seen my client 14 times over 18 months. You saw her once for 12 minutes. Is that correct?”
• “Dr. Smith performed surgery on my client’s shoulder. You performed no procedure, ordered no imaging, and prescribed no treatment. Fair?”
• “Dr. Smith has referred my client to physical therapy, pain management, and neurology. You have referred her to none of those. Correct?”

The treating physician’s longitudinal relationship with the patient carries weight that a snapshot evaluation cannot match. For more on how courts evaluate the relative credibility of treating versus IME physicians, see our guide on using IME findings in court.

Phase Five: Lock the Physician Into Their Own Words

The deposition is where you build your trial cross-examination. Lock the witness into every favorable concession so they cannot retreat at trial.

Key Deposition Goals

Pin down definitions. What does “within normal limits” mean? What does “subjective complaint” mean? Force the physician to define their own terminology on the record. When they use weasel words at trial, you will have the deposition transcript to impeach them.

Eliminate wiggle room. “Is it your opinion, to a reasonable degree of medical certainty, that my client’s injuries are unrelated to the accident?” Get the yes or no. Then ask: “Is there any possibility you could be wrong?” Most physicians will concede the possibility. That concession is gold at trial.

Explore alternative causes. If the physician attributes your client’s pain to degenerative changes or pre-existing conditions, ask:

• Were those degenerative changes symptomatic before the accident?
• Is it possible that the accident aggravated a previously asymptomatic condition?
• Would you agree that an asymptomatic condition that becomes symptomatic after trauma is, in clinical practice, attributed to the trauma?

Test their familiarity with the file. Ask detailed questions about records they claim to have reviewed. A physician who cannot recall key facts from the file has just demonstrated superficial preparation.

Special Considerations by Case Type

Personal Injury Cases

In auto accident and premises liability cases, the defense IME physician will often argue that soft tissue injuries resolve within 6–8 weeks. Prepare to counter with:

• Your client’s specific treatment timeline
• Treating physician notes documenting ongoing symptoms
• The difference between “typical” recovery and your client’s actual course

Workers’ Compensation

IME physicians in workers’ comp cases frequently opine on return-to-work capacity and maximum medical improvement (MMI). These opinions have direct financial consequences for your client. Key cross-examination targets include:

• Whether the physician considered the specific physical demands of your client’s job
• Whether the physician reviewed a job description or simply assumed a “sedentary” classification
• Whether the physician considered the impact of medication side effects on work capacity

Disability Claims

Disability IMEs often turn on functional capacity evaluations (FCEs). If the IME physician did not perform or review an FCE, their opinion on functional limitations may be vulnerable to a Daubert or Frye challenge. Ask:

• Did you conduct a functional capacity evaluation?
• On what basis are you opining about my client’s ability to lift, stand, or sit for extended periods?
• Have you ever observed my client performing work-related activities?

When You Are the One Hiring the IME Physician

Not every cross-examination targets the opposing expert. If you retain the IME physician, you need to prepare them to withstand cross-examination. The quality of your expert determines how much damage the other side can do.

When selecting an IME provider, look for:

• Board certification in the relevant specialty
• Balanced retention history: not exclusively plaintiff or defense
• Rigorous QA processes that ensure reports are internally consistent and well-supported
• Willingness to concede appropriate points: the expert who concedes nothing is the expert the jury stops trusting

MLP IME provides physician expert witness services with board-certified doctors across all 50 states, with internal quality assurance that produces reports built to survive cross-examination. Every physician goes through credential verification, and case managers review each report for clarity, consistency, and completeness before it reaches your desk. When your expert’s report is thorough and their methodology is sound, cross-examination becomes an opportunity to reinforce your case, not undermine it.

The Ethics Dimension

Attorneys have an ethical obligation to conduct cross-examination within the bounds of the rules of evidence and professional conduct. But understanding the ethical obligations on the physician’s side can also be a cross-examination tool.

The AMA Code of Medical Ethics requires IME physicians to:

• Remain impartial
• Base conclusions on clinical evidence
• Disclose potential conflicts of interest.
• Conduct examinations that are thorough enough to support their conclusions.

If the physician’s exam was cursory, their conclusions speculative, or their conflicts undisclosed, you have both a cross-examination target and, in egregious cases, grounds for a motion to strike.
