Inhalant use, unsp w inhalnt-induce psych disord w hallucin

This code signifies a patient presenting with an unspecified pattern of inhalant use that has directly resulted in a psychotic disorder characterized by the presence of hallucinations. The inhalant substance itself is not specified, but its causal link to the psychotic symptoms, specifically hallucinations, is established.

Apply this code when documentation clearly indicates a patient's psychotic symptoms, including hallucinations, are directly attributable to inhalant use, but the specific inhalant substance is not identified. This is appropriate for initial assessments or when a definitive substance cannot be determined despite clear evidence of inhalant-induced psychosis.

• Ensure documentation explicitly links inhalant use to the psychotic disorder and specifies hallucinations.
• Avoid using this code if the specific inhalant substance is known; instead, use a more specific code from the F18.xx series.
• Always sequence this code as the primary diagnosis when the inhalant-induced psychotic disorder is the reason for the encounter.
