ICD-10 Code F18.29 – Inhalant dependence with unspecified inhalant-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.29 – Inhalant dependence with unspecified inhalant-induced disorder
What it is
Use this code for dependence on inhalants when the record also documents an inhalant-induced disorder, but the specific disorder is not named. It indicates a substance use condition tied to inhalant exposure.
Clinical signs
Clinical features vary; refer to documentation. Records may note compulsive inhalant use, tolerance, withdrawal, or functional impairment, along with an unspecified inhalant-related mental or physical disorder.
When to use this code
Use F18.29 when the clinician clearly documents inhalant dependence and states an inhalant-induced disorder without further detail. This may appear in behavioral health, emergency, or inpatient notes. If the induced disorder is specified, code that more precise diagnosis instead.
Do not use for
Do not use this code for inhalant abuse without dependence, or for a clearly identified inhalant-induced disorder that has its own more specific code. Check documentation when the substance or disorder is unclear.
Coding tip
Confirm both dependence and an unspecified inhalant-induced disorder are documented before assigning F18.29.
