Cannabis dependence with intoxication delirium

This code signifies a severe pattern of cannabis use characterized by a physiological and psychological dependence, coupled with the presence of delirium directly induced by cannabis intoxication. Patients exhibit cognitive disturbances, disorientation, and altered consciousness during active cannabis use.

Apply this code when documentation clearly indicates both cannabis dependence and an acute confusional state (delirium) directly attributable to cannabis intoxication. This typically occurs in emergency department settings or inpatient admissions where acute mental status changes are observed in a patient with a history of problematic cannabis use.

• Ensure documentation explicitly links the delirium to cannabis intoxication, not another substance or medical condition.
• Do not code if only cannabis intoxication is present without evidence of dependence.
• Sequence this code as the primary diagnosis if it is the reason for the encounter, followed by any associated physical or mental health conditions.
