Cannabis use, unspecified with intoxication delirium

This code signifies a patient presenting with acute mental status changes, including disorientation, confusion, and impaired cognition, directly attributable to recent cannabis use. The "unspecified" nature indicates that the specific pattern or severity of cannabis use disorder (e.g., mild, moderate, severe) has not been documented.

Apply this code when documentation clearly links a patient's delirium to cannabis intoxication, and the provider has not specified the severity or pattern of cannabis use. This is appropriate for emergency department visits or inpatient admissions where the primary issue is the acute intoxicating effect and associated delirium.

• Requires clear documentation of both cannabis use and the presence of delirium.
• Do not use if the delirium is attributed to other substances or medical conditions.
• Consider sequencing this code as the primary diagnosis if the delirium is the chief complaint and reason for the encounter.
