ICD-10 Code F18.988 – Inhalant use, unspecified with other inhalant-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.988 – Inhalant use, unspecified with other inhalant-induced disorder
What it is
F18.988 identifies inhalant use when the record documents another inhalant-induced disorder, but does not specify a more exact diagnosis. Use this code when inhalant exposure is linked to a related condition and the documentation is limited.
Clinical signs
Clinical features vary; refer to documentation. Records may describe symptoms or behavior consistent with inhalant-related harm, along with a clinician’s diagnosis of another inhalant-induced disorder.
When to use this code
Use F18.988 when the provider documents inhalant use and an associated inhalant-induced disorder, but the exact disorder is not named. It also fits when the chart clearly links the disorder to inhalant exposure and no more specific code is supported. Check documentation if the record only says “inhalant abuse” or “use” without a related disorder.
Do not use for
Do not use this code for uncomplicated inhalant use without an induced disorder. Also avoid it when the documentation names a more specific inhalant-induced condition that can be coded directly.
Coding tip
Code the induced disorder first only if documentation supports it; then assign F18.988 when the inhalant-related condition remains unspecified.
