Alcohol dependence with intoxication delirium

This code signifies a severe pattern of alcohol use characterized by impaired control over drinking, continued use despite adverse consequences, and tolerance or withdrawal symptoms, specifically complicated by the presence of delirium due to acute alcohol intoxication. The patient exhibits significant cognitive and perceptual disturbances, such as disorientation, hallucinations, or illusions, directly attributable to the intoxicating effects of alcohol.

Apply this code when documentation clearly indicates a diagnosis of alcohol dependence alongside an acute episode of delirium caused by alcohol intoxication. This typically occurs in emergency department settings, inpatient admissions for detoxification, or psychiatric evaluations where the patient presents with both chronic alcohol dependence and acute, severe confusion or altered mental status directly linked to recent alcohol consumption.

• Ensure documentation explicitly links the delirium to alcohol intoxication and confirms a diagnosis of alcohol dependence.
• Do not confuse with alcohol withdrawal delirium (delirium tremens), which has a separate code.
• Sequence this code as the primary diagnosis when it is the main reason for the encounter.
