Inhalant use, unsp with inhalant-induced mood disorder

This code signifies a diagnosis of inhalant use disorder where the specific inhalant substance is not documented, and the patient is experiencing a mood disorder directly induced by the inhalant use. This indicates a causal link between the substance use and the mood disturbance, such as depression, anxiety, or irritability.

Apply this code when documentation clearly states inhalant use and an associated mood disorder, but the specific inhalant (e.g., glue, paint thinner, aerosols) is not identified. This is appropriate when a clinician explicitly links the mood symptoms to the inhalant intoxication or withdrawal.

• Requires physician documentation explicitly linking the mood disorder to inhalant use.
• Do not use if the specific inhalant is known; instead, use a more specific F18.x4 code.
• Sequence this code first if the inhalant-induced mood disorder is the primary reason for the encounter.
