Inhalant abuse with inhalant-induced anxiety disorder

This code signifies a diagnosis of inhalant abuse, characterized by a maladaptive pattern of inhalant use leading to clinically significant impairment or distress, specifically complicated by an anxiety disorder directly induced by the inhalant use. The anxiety symptoms are prominent and exceed those expected during intoxication or withdrawal.

Apply this code when documentation clearly indicates a diagnosis of inhalant abuse and a co-occurring anxiety disorder where the anxiety is directly attributable to the physiological effects of inhalant use. Supporting documentation should include a detailed psychiatric evaluation confirming both the substance abuse and the substance-induced anxiety.

• Ensure the documentation explicitly links the anxiety disorder as "inhalant-induced" to justify this specific code.
• Do not use this code if the anxiety disorder predates or is unrelated to the inhalant abuse; in such cases, code both conditions separately.
• Verify the specific inhalant substance if documented, as other F18 subcategories exist for different patterns of abuse.
