to the physiological consequences of another medical condition.
Coding note: Include the name of the other medical condition in the name of the
delirium (e.g., 293.0 [F05] delirium due to hepatic encephalopathy). The other med-
ical condition should also be coded and listed separately immediately before the
delirium due to another medical condition (e.g., 572.2 [K72.90] hepatic encepha-
lopathy; 293.0 [F05] delirium due to hepatic encephalopathy).
293.0 (F05) Delirium due to  multiple etiologies:  There is evidence from the history,
physical examination, or laboratory findings that the delirium has more than one etiol-
ogy (e.g., more than one etiological medical condition; another medical condition plus
substance intoxication or medication side effect).
Coding note:  Use multiple separate codes reflecting specific delirium etiologies
(e.g., 572.2 [K72.90] hepatic encephalopathy, 293.0 [F05] delirium due to hepatic
failure; 291.0 [F10.231] alcohol withdrawal de lirium). Note that the etiological med-
ical condition both appears as a separate code that precedes the delirium code and
is substituted into the delirium due to another medical condition rubric.
