ICD-10 Code F18.14 – Inhalant abuse with inhalant-induced mood disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.14 – Inhalant abuse with inhalant-induced mood disorder
What it is
Use this code for documented inhalant abuse when the patient also has a mood disorder caused by the inhalant. It indicates both the substance misuse and the substance-induced emotional disturbance.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe depressed mood, irritability, or other mood changes linked to inhalant use, with evidence that the mood symptoms are substance induced.
When to use this code
Assign F18.14 when the record clearly states inhalant abuse and identifies a mood disorder as caused by the inhalant. Use it for encounters where the provider links the mood symptoms to inhalant use, not to a separate primary psychiatric condition.
If the documentation only says inhalant abuse without mood symptoms, choose a different code. If the mood disorder is present but the cause is unclear, check documentation before coding.
Do not use for
Do not use this code for inhalant dependence without a mood disorder, or for a primary mood disorder unrelated to inhalant use. Check documentation if the substance relationship is not stated.
Coding tip
Code F18.14 only when the provider explicitly connects the mood disorder to inhalant abuse.
