What This Code Means

A person who is dependent on inhalants and experiencing hallucinations as a result of their inhalant use, which is a form of psychotic disorder.

Coding Tips

•Verify documentation confirms both inhalant dependence and active psychotic symptoms with hallucinations
•Distinguish from F18.250 (delusions) and F18.259 (unspecified psychotic disorder) based on specific hallucination symptoms

Clinical Significance

Inhalant dependence with induced psychotic disorder with hallucinations captures patients experiencing perceptual disturbances (visual, auditory, or tactile hallucinations) caused by chronic inhalant neurotoxicity. Toluene-based solvents are particularly associated with hallucinations. This is a high-acuity condition mapping to the highest substance use HCC.

Documentation Requirements

✓Documentation of inhalant dependence
✓Specific hallucination type documented (visual, auditory, tactile)
✓Provider statement linking hallucinations to inhalant use
✓Mental status examination documenting hallucinations
✓Assessment of insight and safety
✓Neurological examination for other neurotoxic signs
✓Treatment plan for both dependence and psychosis

Commonly Confused Codes
