Hallucinogen abuse with intoxication, uncomplicated

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 the substance without additional complications. It indicates an active state of intoxication from hallucinogens, such as LSD, psilocybin, or PCP, where the primary issue is the immediate psychoactive effects.

Apply this code when documentation clearly indicates a diagnosis of hallucinogen abuse and the patient presents with symptoms of acute intoxication, such as perceptual distortions, mood lability, or impaired judgment, without co-occurring delirium, psychotic features, or other specified complications. This is appropriate for initial evaluations or encounters where the focus is on managing the acute intoxication phase.

• Differentiate from hallucinogen dependence (F16.2-) which implies a more severe pattern of use with tolerance or withdrawal.
• Ensure documentation specifies "abuse" rather than "use" or "dependence" for accurate code selection.
• Do not use if the patient is experiencing hallucinogen-induced psychotic disorder (F16.15-) or delirium (F16.121).
