Malingering is the fabrication, feigning, or exaggeration of physical or psychological symptoms designed to achieve a desired outcome, such as relief from duty or work. Malingering is not a medical diagnosis, but may be recorded as a "focus of clinical attention" or a "reason for contact with health services". Malingering is categorized as distinct from other forms of excessive illness behavior such as somatization disorder and factitious disorder, although not all mental health professionals agree with this formulation. Failure to detect actual cases of malingering imposes an economic burden on health care systems, workers' compensation programs, and disability programs, such as Social Security Disability Insurance and veterans' disability benefits. False accusations of malingering often harm genuine patients or claimants.
