Alcohol withdrawal delirium

This code represents a severe form of alcohol withdrawal characterized by acute brain dysfunction, including disorientation, hallucinations, and significant autonomic instability. It is a medical emergency resulting from abrupt cessation or reduction of prolonged heavy alcohol intake.

Assign this code when documentation clearly indicates delirium (e.g., acute confusion, disorientation, hallucinations) occurring during alcohol withdrawal. This diagnosis requires evidence of recent alcohol cessation or reduction in a patient with a history of alcohol dependence.

• Differentiate from uncomplicated alcohol withdrawal (e.g., tremors, anxiety) which does not involve delirium.
• Ensure documentation specifies "delirium" or similar acute confusional state, not just general withdrawal symptoms.
• Consider sequencing this code as the principal diagnosis when it is the primary reason for admission.
