Hallucinogen use, unsp w psychotic disorder w hallucinations

This code signifies a diagnosis of hallucinogen use disorder where the specific hallucinogen is not identified, and the patient is experiencing a psychotic disorder characterized by hallucinations that are directly induced by the hallucinogen use. This condition involves both substance use and a co-occurring mental health symptomology.

Apply this code when documentation indicates a patient is actively using an unspecified hallucinogen and presents with psychotic symptoms, specifically hallucinations, directly attributable to the substance use. This is appropriate when the clinician cannot specify the exact hallucinogen involved. Supporting documentation would include a clear link between the hallucinogen use and the onset of hallucinations.

• Ensure the documentation explicitly states "unspecified" hallucinogen if the specific substance is unknown.
• Differentiate from other hallucinogen-induced disorders without psychotic features or with other psychotic features (e.g., delusions).
• Sequence this code as the primary diagnosis when the hallucinogen-induced psychotic disorder is the reason for the encounter.
