ICD-10 Code F18.180 – Inhalant Abuse with Inhalant-Induced Anxiety Disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.180 – Inhalant abuse with inhalant-induced anxiety disorder
What it is
F18.180 identifies inhalant abuse associated with an anxiety disorder caused by the inhalant use. Use it when documentation links the anxiety symptoms directly to inhalant misuse rather than to a separate primary anxiety condition.
Clinical signs
Typical findings include anxiety, nervousness, fear, or panic symptoms occurring in the setting of inhalant abuse. Clinical features vary; refer to documentation for the specific substance, timing, and relationship to use.
When to use this code
Use this code when the record clearly states inhalant abuse and an inhalant-induced anxiety disorder. It fits cases where the clinician attributes the anxiety presentation to inhalant use, such as during intoxication, withdrawal, or ongoing misuse. Check documentation if the anxiety disorder is not explicitly substance-induced.
Do not use for
Do not use this code for anxiety disorder unrelated to inhalants, or for inhalant use without documented abuse. If the chart only says inhalant use, dependence, or intoxication, choose the documented condition instead.
Coding tip
Code both the substance pattern and the induced anxiety only when the provider links them clearly in the note.
