Hallucinogen abuse w intoxication w perceptual disturbance

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically when the individual is currently intoxicated and experiencing perceptual disturbances. These disturbances may include illusions, hallucinations, or other sensory distortions that are not better explained by another mental disorder.

Apply this code when documentation clearly indicates a diagnosis of hallucinogen abuse and the patient presents with acute intoxication accompanied by perceptual disturbances. Supporting documentation should detail the hallucinogen use, the current state of intoxication, and specific examples of perceptual alterations observed during the encounter.

• Differentiate from hallucinogen dependence (F16.2-) which implies a more severe pattern of use with tolerance or withdrawal.
• Ensure the documentation specifies "abuse" and not just "use" or "intoxication without abuse."
• Consider additional codes for any co-occurring mental or behavioral disorders, or for specific hallucinogen-induced disorders if applicable.
