IME Doctor vs. Treating Doctor: Who Does the Workers’ Comp Judge Believe?

Who Does the Workers’ Comp Arbitrator Believe: the IME Doctor or the Treating Doctor?

In Illinois workers’ compensation, the arbitrator does not automatically believe either doctor. The treating doctor may get meaningful weight because they usually know the injured worker better and have followed the condition over time. But that is not absolute.

The winning medical opinion is usually the one that best fits:

• the accident history;
• the worker’s symptoms over time;
• medical records before and after the injury;
• MRI, EMG, X-ray, or other diagnostic testing;
• physical exam findings;
• job duties and mechanism of injury;
• work restrictions;
• prior medical history; and
• the injured worker’s testimony.

In plain English: the doctor who gives the more believable, better-supported explanation usually has the stronger opinion.

Can the Workers’ Comp Judge Believe My Treating Doctor Over the IME Doctor?

Yes. An Illinois workers’ comp arbitrator can believe your treating doctor over the insurance company’s IME doctor.

This is especially true when your treating doctor has seen you repeatedly, understands your job duties, reviewed the diagnostic tests, gave consistent restrictions, and explains how your injury or condition is related to work.

A treating doctor who has examined the injured worker 10 times, watched symptoms develop, ordered testing, tried conservative treatment, reviewed the response to care, and explained the need for surgery may have a better picture than an IME doctor who saw the worker once for a short exam.

But the treating doctor still has to make sense. If the history is inconsistent, the diagnostic testing does not match the symptoms, or the doctor’s opinion is based on incomplete information, the arbitrator may give less weight to that opinion.

What Makes a Medical Opinion More Credible in Workers’ Comp?

A strong medical opinion usually does more than say, “This is work-related.” It explains why.

The arbitrator may look at whether the doctor had:

• a clear and accurate history of how the injury happened;
• consistent symptom reports from the injured worker;
• physical exam findings that match the complaints;
• diagnostic testing that supports the diagnosis;
• prior medical records showing what existed before the work injury;
• a good understanding of the worker’s actual job duties;
• records showing whether the worker improved or worsened with treatment; and
• a reasonable explanation connecting the work injury to the medical condition.

If the doctor’s opinion fits the records, tests, history, and testimony, it is usually easier to defend. If it feels stretched, unsupported, or incomplete, the insurance company will attack it — and the arbitrator may not accept it.

Why Job History, Diagnostic Tests, and Records Matter So Much

In many IME disputes, the fight is not just about which doctor is more likable or more qualified. The fight is about which doctor had the better foundation for their opinion.

For example, in a repetitive trauma case, one doctor may have a detailed description of the worker’s job: how often the worker lifts, how much the items weigh, whether the work is overhead, what tools are used, what ergonomic problems exist, and how many repetitions happen during a shift.

Another doctor may only know that the worker “does some lifting.” Those are not the same histories.

The more detailed job history can make a medical opinion more credible. A job video, ergonomic breakdown, written job description, coworker testimony, or detailed explanation of the work duties can make a major difference.

For more on proving these claims, read our guide on how to prove a repetitive trauma injury in Illinois workers’ comp.

Records matter too. If one doctor reviewed prior MRI studies, old treatment records, accident reports, and the full medical history — and the other doctor did not — that may affect which opinion the arbitrator finds more credible.

The Injured Worker’s Credibility Still Matters

Even when the case is about medical opinions, the injured worker’s credibility still matters.

The arbitrator will look at whether the worker’s story is consistent with the medical records, accident report, diagnostic tests, and testimony. If the worker gives one history to the ER, a different history to the treating doctor, another version to the IME doctor, and something else at trial, that can hurt the case.

Credibility does not just mean whether the arbitrator thinks the worker is a good person. It also means whether the evidence is strong enough to support a believable medical finding.

If the symptoms, timeline, job duties, diagnostic tests, and treatment records all fit together, the treating doctor’s opinion is usually easier to defend.

How We Cross-Examine IME Doctors in Workers’ Comp Trials

When we take an IME doctor’s evidence deposition for a workers’ comp trial, we look for the weak points.

We usually ask how often the doctor performs IMEs, how often those IMEs are requested by insurance companies or defense lawyers, and how much the doctor is paid for the exam, report, and testimony.

Some doctors perform hundreds of IMEs per year, and the vast majority are for insurance companies. That does not automatically mean the doctor is wrong, but it is fair to ask whether bias may be part of the picture.

At the same time, treating doctors can have their own incentives too. A treating doctor may bill for treatment or surgery. The arbitrator knows that. The point is not that one side is always biased and the other side is always pure. The point is to test each opinion and see which one holds up better.

Good cross-examination can expose problems such as:

• the IME doctor did not review all relevant records;
• the IME doctor ignored prior imaging or prior treatment;
• the IME doctor misunderstood the worker’s job duties;
• the IME doctor minimized objective MRI or EMG findings;
• the IME doctor called a serious injury a minor strain;
• the IME doctor blamed degeneration in a young worker when that explanation does not make sense;
• the IME doctor spent very little time examining the worker;
• the IME doctor relied too heavily on exaggeration or validity testing; or
• the IME doctor’s opinion does not match the full medical timeline.

This is why experience matters. Some IME doctors say things in deposition that are not obvious from their written reports. If you have deposed the same doctor many times, you may know where to push, what questions matter, and what concessions the doctor may make under oath.

For example, some IME doctors will admit on cross-examination that certain tests used to suggest exaggeration are only one factor, not the whole case. A worker may be nervous, defensive, in pain, or uncomfortable during an IME. That nuance may not appear in the written report unless someone asks the right questions.

Doctor Reputation and Bias Can Matter Too

Workers’ comp arbitrators and commissioners see many of the same doctors over and over again.

If an IME doctor always seems to say every injury is unrelated, degenerative, or only a minor strain, the arbitrator may remember that pattern. If a treating doctor or chiropractor always seems to say every condition is severe, work-related, and requires major treatment, the arbitrator may remember that too.

That does not mean a doctor wins or loses because of reputation alone. But reputation can affect how the testimony is received, especially when the case is close.

The strongest opinions are usually the ones that are specific, well-documented, medically reasonable, and consistent with the facts.

IME Disputes Often Lead to Denied Surgery or Stopped Checks

IME disputes become serious because the insurance company often uses the IME report to take action. They may stop TTD checks, deny medical care, refuse surgery, or claim the worker can return to full duty.

If the treating doctor says the worker needs surgery and the IME doctor says the surgery is unrelated or unnecessary, the case may need a hearing. If the treating doctor keeps the worker off work but the IME doctor releases the worker to full duty, the case may involve back pay and stopped checks.

These are not small disputes. They can affect whether the injured worker gets treatment, gets paid, and has leverage in settlement.

Real Case Example: Denied Neck Surgery After an IME

We recently handled a serious Illinois workers’ comp case where the insurance company relied on an IME to deny neck surgery and TTD benefits. We took the treating surgeon’s deposition, cross-examined the IME doctor, tried the case, won the surgery and back pay, and defended the win through appeals.

That case is a good example of why the IME report is not the end of the story. The evidence still has to be tested. The doctors still have to explain their opinions. The arbitrator still has to decide which medical opinion makes more sense.

IME Disputes, Surgery Denials, and Trial Wins

IME disputes are often part of larger denied-surgery and trial disputes. McHargue & Jones has tried Illinois workers’ comp cases where insurance companies refused to approve surgery or relied on IME opinions to deny benefits.

See examples of disputed cases we have fought in our Illinois workers’ compensation trial wins where surgeries were approved.

Prior results do not guarantee a similar outcome. Every case depends on its own facts, medical evidence, testimony, doctors, and applicable law.

Bottom Line: The Better-Supported Medical Opinion Usually Wins

In close cases, the Commission may try to give the injured worker and treating doctor the benefit of the doubt. But the arbitrator will not stretch forever. The medical opinion still has to be credible, supported, consistent, and medically reasonable.

The best way to fight a bad IME is to build the evidence around it: medical records, diagnostic tests, prior records, job-duty proof, treating doctor testimony, injured-worker testimony, and cross-examination of the IME doctor.

At McHargue & Jones, we try these cases, take doctor depositions, cross-examine IME doctors, and fight for injured workers when the insurance company uses a weak IME to deny benefits.

FAQ: IME Doctor vs. Treating Doctor in Illinois Workers’ Comp

Does the workers’ comp judge have to believe the IME doctor?

No. The arbitrator can believe the treating doctor over the IME doctor if the treating doctor’s opinion is better supported by the medical records, diagnostic tests, history, examination findings, job duties, and testimony.

Does the treating doctor always beat the IME doctor?

No. The treating doctor’s opinion still has to make sense. The history, symptoms, records, diagnostic tests, and medical explanation need to support the opinion.

What makes an IME opinion weak?

An IME opinion may be weak if the doctor did not review all records, misunderstood the job duties, ignored diagnostic testing, spent very little time examining the worker, or reached conclusions that do not fit the medical timeline.

Can cross-examining the IME doctor help?

Yes. Cross-examination can expose bias, incomplete record review, weak assumptions, overstatements, and concessions that were not included in the written IME report.

What if the IME doctor says I am exaggerating?

That opinion can be challenged. Some exaggeration or validity tests are only one part of an exam and are not automatically dispositive. Nervousness, pain, defensiveness, and the setting of an IME may affect how a person presents during the exam.

What happens if my IME doctor says I can work but my treating doctor says I cannot?

The dispute may need to be presented to an arbitrator. The arbitrator can consider both opinions, the medical records, restrictions, diagnostic tests, job duties, and testimony to decide whether TTD benefits should continue or be restarted.
