ICD-10 Code F18.10 – Inhalant abuse, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.10 – Inhalant abuse, uncomplicated
What it is
F18.10 identifies uncomplicated inhalant abuse, meaning harmful use of inhaled substances without documented intoxication, dependence, or other specified complications. Use it when the record clearly supports abuse of inhalants.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include a pattern of misuse, impaired control, or continued use despite harm, but the chart should support abuse rather than another substance-related disorder.
When to use this code
Use F18.10 when the provider documents inhalant abuse and does not describe intoxication, withdrawal, dependence, or another inhalant-related condition. It may also apply when the note states “uncomplicated” or gives no additional qualifying detail. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for inhalant intoxication, dependence, or substance-induced mental disorder. It is also inappropriate when the substance is not an inhalant or when the documentation supports a different substance use diagnosis.
Coding tip
Match the code to the exact wording in the provider note and avoid assuming “abuse” when the chart supports dependence or intoxication.
