ICD-10 Code F18.25 – Inhalant dependence with inhalant-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.25 – Inhalant dependence with inhalant-induced psychotic disorder
What it is
This code identifies inhalant dependence when the patient also has a psychotic disorder caused by inhalant use. It reflects both the substance dependence and the substance-induced mental disturbance.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic findings may include hallucinations, delusions, or marked disorganized thinking occurring in the context of inhalant use.
When to use this code
Use this code when the record clearly documents inhalant dependence and a psychotic disorder attributed to inhalant exposure. You should have provider support that the psychosis is substance-induced, not a primary psychiatric condition. If the relationship is unclear, check documentation.
Do not use for
Do not use this code for inhalant use without dependence, or for psychosis not linked to inhalant use. If the record only states intoxication, abuse, or unspecified use, choose the documented diagnosis instead.
Coding tip
Confirm both dependence and the inhalant-induced psychotic disorder are documented before assigning F18.25.
