What This Code Means

A person with inhalant use (not dependent) experiencing psychotic symptoms from inhalants, but the specific type of psychotic disorder is not specified.

Coding Tips

• •Document whether hallucinations, delusions, or both are present to potentially use more specific codes
• •Verify the psychotic symptoms are inhalant-induced rather than a primary psychotic disorder

Clinical Significance

This code captures substance-induced psychotic disorder, which represents a serious psychiatric complication of inhalant use. Substance-induced psychosis significantly increases healthcare utilization, emergency department visits, and hospitalization risk, making accurate capture critical for risk adjustment. These patients require intensive psychiatric management and close monitoring for progression to chronic psychotic disorders.

Documentation Requirements

• ✓Provider documentation of inhalant use, specifying the type of inhalant when known (e.g., toluene, gasoline, aerosol propellants, nitrites)
• ✓Documentation of substance use pattern; query provider to determine if abuse or dependence criteria are met for more specific coding
• ✓Documentation of psychotic symptoms (delusions and/or hallucinations) with provider statement that they are substance-induced rather than a primary psychotic disorder
• ✓Assessment and plan addressing the substance use disorder with treatment approach documented
