ICD-10 Code F18.950 – Inhalant use, unspecified with inhalant-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.950 – Inhalant use, unspecified with inhalant-induced psychotic disorder with delusions
What it is
This code identifies inhalant use, when the patient has a psychotic disorder caused by inhalants and the psychosis includes delusions. Use it when the record links the psychotic symptoms directly to inhalant use.
Clinical signs
Typical findings include fixed false beliefs, impaired reality testing, and other psychotic features occurring in the context of inhalant use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents inhalant use, unspecified, along with an inhalant-induced psychotic disorder with delusions. It fits cases where the psychotic condition is attributed to inhalants rather than a primary psychotic disorder. Check documentation if the substance, severity, or psychotic subtype is unclear.
Do not use for
Do not use it for delusions without documented inhalant-related psychosis, or for psychosis caused by another substance. Do not assign it if the record does not support inhalant use as the cause.
Coding tip
Confirm both the inhalant use and the substance-induced psychotic disorder with delusions are documented before assigning F18.950.
