Alcohol dependence with withdrawal delirium

This code signifies a severe form of alcohol use disorder characterized by a physiological dependence on alcohol, coupled with the acute onset of delirium during alcohol withdrawal. Patients typically experience profound confusion, disorientation, hallucinations, and autonomic instability (e.g., tremors, fever, tachycardia) upon cessation or reduction of alcohol intake.

Apply this code when documentation clearly indicates a diagnosis of alcohol dependence and the presence of withdrawal delirium. This typically occurs in acute care settings, such as emergency departments or inpatient units, where patients are admitted for severe alcohol withdrawal symptoms. Supporting documentation includes physician notes detailing the diagnostic criteria for both alcohol dependence and delirium.

• Ensure documentation explicitly states "delirium" in the context of alcohol withdrawal, not just "withdrawal."
• Do not confuse with F10.232 (Alcohol dependence with withdrawal with perceptual disturbance) if delirium is not present.
• Sequence as the primary diagnosis when it is the reason for the encounter or admission.
