Oth psychoactv substance use, unsp w psych disorder, unsp

This code signifies a patient presenting with a psychotic disorder that is directly induced by the use of an unspecified psychoactive substance. The specific substance involved is not identified, and the nature of the psychotic disorder (e.g., delusions, hallucinations) is also not specified. This diagnosis indicates a direct causal link between substance use and the onset of psychotic symptoms.

Use this code when documentation clearly indicates a substance-induced psychotic disorder, but the specific psychoactive substance responsible is unknown or not documented. This is appropriate when the clinician has ruled out other causes of psychosis and attributes the symptoms to substance use, but further specificity regarding the substance is lacking.

• Avoid using this code if the specific psychoactive substance is known; instead, use a more specific F1x.95x code.
• Ensure documentation explicitly states "substance-induced" and "psychotic disorder" to support this diagnosis.
• This code should be sequenced as a primary diagnosis when the substance-induced psychotic disorder is the reason for the encounter.
