Hallucinogen abuse with intoxication, unspecified

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically when the individual is currently experiencing the acute effects of hallucinogen intoxication. It indicates a maladaptive pattern of substance use without dependence.

Apply this code when documentation clearly indicates a patient is experiencing acute intoxication from hallucinogen use, and their use meets the criteria for abuse (e.g., recurrent use resulting in failure to fulfill major role obligations, physically hazardous situations, or legal problems). Supporting documentation would include a diagnosis of hallucinogen abuse and signs/symptoms of current intoxication.

• Differentiate from hallucinogen dependence (F16.2-) which implies tolerance or withdrawal.
• Ensure documentation specifies "abuse" rather than "use" or "dependence."
• If a specific hallucinogen is identified (e.g., LSD, PCP), use a more specific subcategory if available.
