How to Challenge the Other Side’s Medical Expert

In many personal injury and medical malpractice cases, the other side hires its own medical expert. That expert may argue that the injuries are less serious than claimed, that they were caused by something other than the incident, or that the care provided met accepted standards. Because juries and insurance adjusters often give significant weight to medical opinions, an opposing expert’s testimony can have a major effect on the value of a case. Challenging that testimony effectively requires preparation, careful review, and an understanding of the rules that govern expert evidence. Learning how medical malpractice claims in Pennsylvania handle expert disputes may be helpful. This article explains how opposing experts are used and the main ways their opinions can be tested.

How the Other Side Uses Medical Experts

Opposing medical experts appear in different ways depending on the type of case. Understanding their role is the first step in evaluating their opinions.

Defense Medical Examinations

In personal injury cases, the defense may request that the injured person be examined by a physician of its choosing. Pennsylvania’s rules of civil procedure allow these examinations in certain circumstances when a person’s physical or mental condition is at issue. Although sometimes called independent medical examinations, the physician is typically selected and paid by the defense, and the examination is often brief compared to the care provided by treating doctors. Preparing for the examination, and understanding what it will involve, can help the injured person participate accurately and avoid misunderstandings.

Standard of Care and Causation Experts

In medical malpractice cases, defense experts often testify that a provider’s care met accepted standards or that the patient’s outcome would have been the same regardless of the care received. Experts may also address causation in other injury cases, suggesting that symptoms stem from age, preexisting conditions, or later events rather than the incident in question. These opinions can be persuasive when presented confidently, which is why examining the reasoning behind them is so important.

Examining the Expert’s Qualifications and Background

An expert’s opinion is only as strong as the qualifications and credibility behind it. Reviewing the expert’s background is often one of the most important early steps.

Relevant Training and Experience

An expert should have training and experience that fit the specific medical issues in the case. In Pennsylvania medical malpractice cases, the law generally requires standard-of-care experts to have qualifications related to the specialty of the provider being evaluated, including recent clinical practice or teaching in many situations. An expert who practices in a different field, or who has not treated patients in years, may be open to questions about whether their opinions carry the same weight.

Potential Bias

Questions about bias often focus on how frequently the expert testifies, whether they work mostly for defendants or insurers, and how much they are paid for their work. Prior testimony in other cases may reveal patterns or opinions that conflict with their current position. While these factors do not automatically disqualify an expert, they can help a jury evaluate the testimony in context.

Testing the Substance of the Opinions

Beyond credentials, the reasoning behind an expert’s opinions can be examined closely. Weaknesses in methodology or factual basis may significantly reduce an opinion’s persuasiveness.

Gaps in the Records Reviewed

An expert may have relied on incomplete records, overlooked imaging results, or failed to consider the observations of treating providers. Comparing the expert’s report against the full medical history can reveal important omissions. When an opinion rests on a limited or inaccurate set of facts, its conclusions may be called into question.

Inconsistencies and Unsupported Conclusions

Expert reports sometimes contain internal contradictions or conclusions that go beyond what the evidence supports. An expert may acknowledge a finding in one part of a report while downplaying it elsewhere. Pointing out these inconsistencies during depositions or cross-examination can help highlight the limits of the opinion.

Comparing Against Treating Providers

Treating physicians have often seen the injured person many times over an extended period. Their observations may carry significant weight when contrasted with an expert who conducted a single examination or only reviewed records. Presenting the treating providers’ perspective can offer a fuller picture of the injury.

Legal Tools for Challenging Expert Testimony

Pennsylvania law offers several procedural avenues for addressing expert evidence before and during trial.

Expert Reports and Depositions

Expert discovery in Pennsylvania often involves the exchange of written reports that outline the expert’s opinions and the basis for them. Depending on the court and circumstances, expert depositions may also occur. Careful review of these materials allows each side to prepare targeted questions and identify issues that may be raised later.

Admissibility Challenges

Pennsylvania courts evaluate whether novel scientific evidence is admissible under a standard that looks at whether the methodology is generally accepted in the relevant scientific community. When an expert relies on questionable methods, a party may ask the court to limit or exclude the testimony. Courts may also restrict testimony that goes beyond the scope of an expert’s report. These challenges are typically raised through pretrial motions, and the outcome depends on the specific opinions and the evidence supporting them.

Presenting a Qualified Responding Expert

One of the most effective ways to address an opposing expert is often to present testimony from a well-qualified expert who can explain why the other side’s conclusions are incomplete or incorrect. A responding expert may review the same records, point out overlooked findings, and describe accepted medical principles in clear terms. When jurors hear competing opinions, the quality of the reasoning and the expert’s credibility often matter more than credentials alone.

Responding to Opposing Medical Opinions

An opposing medical expert can shape how an injury claim is viewed, but those opinions can often be examined, tested, and challenged.
