Hallucinogen abuse w psychotic disorder w hallucinations

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically characterized by the presence of a hallucinogen-induced psychotic disorder where the predominant symptoms are hallucinations. This indicates a direct causal link between hallucinogen use and the onset of psychotic symptoms, primarily involving sensory perceptions not based in reality.

Apply this code when a patient presents with a documented history of hallucinogen abuse and is actively experiencing hallucinations directly attributable to their hallucinogen use. Documentation should clearly establish the link between the substance and the psychotic symptoms, ruling out other primary psychotic disorders. This code is appropriate for both acute presentations and ongoing management of this specific substance-induced condition.

• Ensure documentation explicitly states "hallucinations" as the primary psychotic symptom, not delusions or other psychotic features.
• Differentiate from F16.150 (with delusions) or F16.159 (unspecified psychotic disorder) based on the specific psychotic symptom documented.
• Always sequence this code as the primary diagnosis when the hallucinogen-induced psychotic disorder is the reason for the encounter, followed by codes for any associated physical or mental health conditions.
