Inhalant dependence with inhalant-induced anxiety disorder

This code signifies a patient's physiological and psychological dependence on inhalants, accompanied by an anxiety disorder directly caused by their inhalant use. The anxiety symptoms are not merely co-occurring but are a direct consequence of the inhalant intoxication or withdrawal.

Use this code when documentation clearly indicates a diagnosis of inhalant dependence and a co-occurring anxiety disorder that the clinician explicitly links as being induced by the inhalant use. This typically applies to patients presenting with chronic inhalant abuse and anxiety symptoms that resolve or significantly improve with cessation of inhalant use.

• Ensure the documentation explicitly states "inhalant-induced anxiety disorder" and not just co-occurring anxiety.
• Distinguish from F18.288 (other inhalant-induced mental disorder) if anxiety is the primary and most prominent mental health symptom.
• Sequence this code as the primary diagnosis when the inhalant dependence and induced anxiety are the main reason for the encounter.
