DSM-IV: Delirium Due to Multiple Etiologies

Delirium may result from a combination of multiple causes.

Diagnostic criteria for Delirium Due to Multiple Etiologies

A. Disturbance of consciousness (i.e., reduced clarity of awareness of the environment) with reduced ability to focus, sustain, or shift attention.

B. A change in cognition (such as memory deficit, disorientation, language disturbance) or the development of a perceptual disturbance that is not better accounted for by a preexisting, established, or evolving dementia.

C. The disturbance develops over a short period of time (usually hours to days) and tends to fluctuate during the course of the day.

D. There is evidence from the history, physical examination, or laboratory findings that the delirium has more than one etiology (e.g. more than one etiological general medical condition, a general medical condition plus Substance Intoxication or medication side effect).

Coding note: Use multiple codes reflecting specific delirium and specific etiologies, e.g. 293.0 Delirium Due to Viral Encephalitis; 291.0 Alcohol Withdrawal Delirium.
