Independent Medical Examinations: Understanding IMEs in Injury Claims

At some point in a contested personal injury claim, a claimant may be asked, or in litigation, required, to attend an examination with a doctor they have never met before, chosen and paid for by the insurance company or opposing party. Independent medical examinations, commonly called IMEs, are a standard feature of personal injury claims, and understanding their purpose and the rules that govern them helps claimants know what to expect.

What an IME Is, and What It Isn't

Despite the name, an independent medical examination is not truly independent in the sense of being neutral by design; the examining physician is retained and paid by the insurer or defense side of the case. The examination itself typically involves a physical evaluation, a review of medical history and records, and questions about the claimant's symptoms and daily functioning. The resulting report becomes evidence that can be used to challenge the claimant's own treating physicians' conclusions, particularly around the extent of injury and, importantly, causation of injuries.

The Role of IMEs in Evaluating Causation

One of the most significant functions of an IME is addressing causation, meaning whether the claimed injuries were actually caused by the accident in question, as opposed to a pre-existing condition or an unrelated event. Defense-retained examiners frequently focus heavily on this question, since disputing causation, rather than the existence of an injury altogether, is often a more effective claim defense strategy.

California's Legal Framework

In California litigation, IMEs are governed in significant part by California Code of Civil Procedure Section 2032, which sets out the process for demanding a physical or mental examination once a lawsuit has been filed. Generally, a defendant is entitled to one physical examination without needing court approval, provided proper notice requirements are met, while additional examinations or more invasive procedures typically require a court order upon a further showing of good cause.

Claimant Rights and Obligations During an IME

• Claimants generally have the right to be informed in advance of the scope, time, and place of the examination.
• Claimants typically have the right to have an observer present, though rules on recording the exam vary and should be confirmed with counsel.
• The examination must generally be limited to conditions genuinely at issue in the case, not an unrelated full-body workup.
• Claimants are usually entitled to receive a copy of the resulting written report.

How an IME Report Gets Used After the Exam

Once the examination is complete, the examining physician prepares a written report summarizing findings, often including an opinion on diagnosis, causation, and prognosis. This report is then shared with the attorneys on both sides and typically becomes part of the evidentiary record for the case. Where the IME report conflicts with a treating physician's conclusions, which happens fairly often given each doctor's differing role and incentive structure, the case may ultimately be resolved through negotiation informed by both reports, or, if the case proceeds to trial, through competing expert testimony that lets a jury weigh the two opinions directly.

Preparing for an IME

Claimants attending an IME are generally advised to answer questions honestly and consistently, describe symptoms accurately without exaggeration or minimization, and avoid volunteering unnecessary information beyond what is asked. Because the examining physician's report can carry significant weight in the claim, being straightforward and consistent with prior medical records is typically far more effective than trying to over-perform or under-perform symptoms during the exam.

Arriving prepared also means bringing basic practical items: identification, a list of current medications, and a general understanding of one's own treatment timeline. Claimants represented by an attorney often receive a short pre-exam briefing covering what to expect, since the exam itself is typically brief relative to the weight its resulting report can carry in the overall claim.

Independent medical examinations exist because both sides of a contested claim need a fair opportunity to evaluate the medical evidence. Understanding the legal framework and rights involved helps claimants approach the process as a standard, manageable part of a personal injury case rather than an intimidating unknown.
