ICD-10 Code F18.250 – Inhalant dependence with inhalant-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.250 – Inhalant dependence with inhalant-induced psychotic disorder with delusions
What it is
This code identifies inhalant dependence together with a psychotic disorder caused by inhalant use, specifically involving delusions. Use it when the documentation links the delusional psychosis directly to inhalant dependence.
Clinical signs
Clinical features include persistent inhalant dependence and psychotic symptoms such as fixed false beliefs. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states inhalant dependence and an inhalant-induced psychotic disorder with delusions. The documentation should show that the psychosis is substance-induced, not a primary psychotic disorder. If the chart does not clearly connect the delusions to inhalant use, check documentation.
Do not use for
Do not use this code for inhalant abuse or uncomplicated dependence without psychosis. Do not use it when delusions are due to another mental disorder or when the substance relationship is not documented.
Coding tip
Confirm both the dependence diagnosis and the inhalant-induced psychotic disorder with delusions in the provider note before assigning F18.250.
