Misdiagnosis, or an incorrect diagnosis, of illness is one of the most common forms of medical malpractice in the U.S. Misdiagnosis may have serious consequences for patients by delaying possibly life-saving treatment, and putting the victim through unnecessary procedures which expose them to unnecessary risk. A misdiagnosis lawyer is a lawyer who has specific expertise related to cases of misdiagnosis. This includes having in-depth knowledge of how misdiagnosis may constitute negligence and put the physician at fault for injuries which have been suffered. A misdiagnosis lawyer also has expertise in putting together a case which reflects the mental anguish which is suffered by victims of misdiagnosis in addition to the physical disabilities and medical expenses accumulated.
