Hallucinogen dependence w psychotic disorder, unsp

This code signifies a severe pattern of hallucinogen use characterized by tolerance, withdrawal, and compulsive drug-seeking behavior, co-occurring with a psychotic disorder directly induced by the hallucinogen. The psychotic symptoms, such as hallucinations or delusions, are not better explained by another mental disorder. The specific type of hallucinogen or the specific psychotic features are not documented.

Apply this code when documentation clearly indicates a patient meets criteria for hallucinogen dependence and is experiencing a psychotic disorder directly attributable to hallucinogen use, but the specific hallucinogen or the precise nature of the psychotic symptoms are not specified. This is appropriate when a definitive diagnosis of dependence and an induced psychosis is made, but further detail is lacking.

• Ensure documentation explicitly links the psychotic disorder to hallucinogen use; otherwise, consider codes for primary psychotic disorders or hallucinogen abuse.
• If the specific hallucinogen is known (e.g., LSD, PCP), or if the specific psychotic features are documented (e.g., with delusions, with hallucinations), a more specific code within the F16.25- subcategory should be used.
• Always sequence this code as a primary diagnosis when it is the focus of treatment, or as a secondary diagnosis if it significantly impacts the patient's care for another primary condition.
