Oth psychoactv sub use, unsp w psych disorder w hallucin

This code signifies a diagnosis of a mental disorder characterized by psychotic symptoms, specifically hallucinations, that are directly caused by the use of an unspecified psychoactive substance. The substance itself is not identified, and the overall pattern of use is also unspecified.

Apply this code when documentation clearly indicates a substance-induced psychotic disorder with hallucinations, and the specific psychoactive substance responsible is not identified. This diagnosis requires a direct causal link between substance use and the onset of psychotic symptoms.

• Ensure documentation explicitly states "hallucinations" as the psychotic symptom.
• Avoid this code if the specific psychoactive substance is known; instead, use a more specific code from the F10-F19 range.
• Sequence this code after any codes for acute intoxication or withdrawal if present and clinically relevant.
