Hallucinogen abuse with intoxication with delirium

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically when the individual is experiencing acute intoxication accompanied by delirium. This involves both the physiological effects of the hallucinogen and a disturbance in attention, awareness, and cognition.

Apply this code when documentation clearly indicates a patient's current hallucinogen abuse and they present with symptoms of acute intoxication, coupled with an altered mental state consistent with delirium. This requires physician documentation of both hallucinogen abuse and the co-occurrence of intoxication and delirium.

• Ensure documentation differentiates between hallucinogen abuse and dependence; this code is for abuse.
• Verify that delirium is explicitly documented as part of the intoxication, not just general confusion or disorientation.
• Consider sequencing with codes for any associated physical injuries or medical conditions resulting from the intoxication or delirium.
