ICD-10 Code F18.18 – Inhalant abuse with other inhalant-induced disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.18 – Inhalant abuse with other inhalant-induced disorders
What it is
Use this code for documented inhalant abuse when the patient also has another inhalant-induced disorder. It identifies harmful use of inhaled substances, such as volatile solvents or aerosols, with an associated mental or physical effect.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include intoxication, behavioral changes, impaired coordination, or other substance-induced complications linked to inhalant use.
When to use this code
Assign F18.18 when the provider documents inhalant abuse plus a separate inhalant-induced disorder that is not captured by a more specific code. Use the record to confirm both the abuse pattern and the related disorder. If the exact induced condition is unclear, check documentation before coding.
Do not use for
Do not use this code for simple inhalant use without abuse, or when the record only describes intoxication or dependence. Check documentation if the provider names a different substance-related disorder.
Coding tip
Code the inhalant-induced disorder only when the provider clearly links it to inhalant abuse in the documentation.
