Inhalant abuse with inhalant-induced mood disorder

This code signifies a diagnosis of inhalant abuse, characterized by a maladaptive pattern of inhalant use leading to clinically significant impairment or distress. Crucially, it also indicates the presence of a co-occurring mood disorder that is directly induced by the physiological effects of inhalant use.

Apply this code when documentation clearly states a diagnosis of inhalant abuse and explicitly links a mood disorder (e.g., depression, anxiety, bipolar-like symptoms) to the inhalant use. This typically occurs in psychiatric evaluations or substance abuse treatment settings where a causal relationship between the inhalant and the mood disturbance has been established.

• Ensure the documentation explicitly states "inhalant-induced" mood disorder, not merely co-occurring mood disorder.
• Do not use this code if the mood disorder predates or is unrelated to the inhalant abuse; consider F18.10 with a separate mood disorder code.
• Always review for any associated intoxication, withdrawal, or other inhalant-induced disorders to ensure comprehensive coding.
