ICD-10 Code F18.251 – Inhalant dependence with inhalant-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.251 – Inhalant dependence with inhalant-induced psychotic disorder with hallucinations
What it is
F18.251 identifies inhalant dependence with a psychotic disorder caused by inhalant use, specifically with hallucinations. Use it when the record shows both dependence and hallucinations linked to inhalant intoxication or use.
Clinical signs
Expect documented hallucinations, along with evidence of inhalant dependence such as compulsive use, tolerance, or withdrawal behavior. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents inhalant dependence and an inhalant-induced psychotic disorder with hallucinations in the same encounter. It fits cases where hallucinations are attributed to inhalant use, not to a primary psychotic disorder. If the chart does not clearly connect the psychosis to inhalants, check documentation.
Do not use for
Do not use this code for inhalant abuse, uncomplicated dependence, or psychosis not caused by inhalants. If hallucinations are present without a documented inhalant-induced disorder, choose the more accurate diagnosis.
Coding tip
Confirm both dependence and the inhalant-induced hallucinations are explicitly documented before assigning F18.251.
