ICD-10 Code F18.951 – Inhalant use, unspecified with inhalant-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.951 – Inhalant use, unspecified with inhalant-induced psychotic disorder with hallucinations
What it is
This code identifies inhalant use, unspecified, complicated by a psychotic disorder with hallucinations caused by the inhalant. Use it when the record links hallucinations directly to inhalant use.
Clinical signs
Documented findings may include hallucinations, disorganized thinking, or other psychotic symptoms occurring in the setting of inhalant use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician states that inhalant use has produced a psychotic disorder with hallucinations. It fits records describing substance-induced hallucinations rather than a primary psychotic disorder. If the substance is named, confirm the documentation supports inhalant-related causation.
Do not use for
Do not use this code for hallucinations without a documented inhalant cause. Do not use it when the psychosis is better explained by another substance, a medical condition, or a primary psychiatric disorder.
Coding tip
Verify that both inhalant use and hallucinations are explicitly documented as linked before assigning F18.951.
