Independent medical examination

An independent medical examination (IME) is a medical evaluation performed on a patient by a medical professional who was not previously involved in the treatment of that patient, to evaluate the patient's course of prior treatment and current condition. IMEs are conducted by doctors, psychologists, and other licensed healthcare professionals in essentially all medical disciplines, depending on the purpose of the exam and the claimed injuries.
