ICD-10 Code F18.151 – Inhalant abuse with inhalant-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.151 – Inhalant abuse with inhalant-induced psychotic disorder with hallucinations
What it is
This code identifies inhalant abuse complicated by a psychotic disorder with hallucinations caused by the inhalant use. Use it when the record links the psychotic symptoms directly to inhalant exposure.
Clinical signs
Documented hallucinations, delusions, or other psychotic symptoms may appear during or after inhalant use. Clinical features vary; refer to documentation for the specific substance, timing, and mental status findings.
When to use this code
Use this code when the clinician states inhalant abuse and separately documents an inhalant-induced psychotic disorder with hallucinations. It is appropriate when hallucinations are attributed to inhalant use rather than a primary psychotic disorder. Check documentation for the causal relationship and whether the condition is acute or ongoing.
Do not use for
Do not use this code if hallucinations are unrelated to inhalant use or if the record only notes inhalant use without psychosis. Do not use it when documentation supports a different substance-related disorder. Check documentation.
Coding tip
Verify that the provider explicitly connects the hallucinations to inhalant abuse before assigning F18.151.
