An independent medical examination (IME) is a medical examination of a personal injury claimant or plaintiff by a medical doctor, psychologist, or other health care provider who is not the claimant or plaintiff’s treating physician or health care provider.

For example, an insurance company (insurer) may request an IME of a workers’ compensation claimant to determine the nature of the injury and provide an expert opinion on whether the injury was caused by a recent workplace accident or is a preexisting injury. Or a defendant (or the defendant’s insurer) may request an IME of a personal injury claimant or plaintiff during the investigation or litigation of a liability claim related to a motor vehicle accident or other incident.

The purpose of an IME is to provide an expert opinion from the treating physician for purposes of defending the claim or litigation—not to provide the injured claimant or plaintiff with a second opinion or with medical treatment. The physician conducting the IME will typically review the medical records of the claimant or plaintiff, interview and evaluate the claimant or plaintiff during the IME, and prepare a report with the physician’s findings (an IME report).

A claimant or plaintiff generally must submit to an IME or lose the right to pursue the insurance claim (workers’ compensation) or liability claim in litigation.

In Maine, an Independent Medical Examination (IME) is a tool used by insurance companies or defendants in personal injury cases, including workers' compensation and liability claims arising from incidents such as motor vehicle accidents. The IME is conducted by a medical professional who has not previously treated the claimant. Its purpose is to obtain an objective assessment of the claimant's injuries to determine the extent of the injuries, their relation to the claimed incident, and the appropriate compensation. The medical professional will review medical records, interview, and examine the claimant, then produce an IME report with their findings. While the IME is not intended to provide medical treatment or a second opinion to the claimant, it is often a required step in the claims process. Failure to comply with a request for an IME can result in the claimant losing the right to pursue their claim. Maine's workers' compensation laws and civil procedure rules outline the specific circumstances under which an IME may be requested and the rights and obligations of the parties involved.
