ICD-10 Code F18.920 – Inhalant use, unspecified with intoxication, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.920 – Inhalant use, unspecified with intoxication, uncomplicated
What it is
F18.920 identifies inhalant use, unspecified, when the patient is intoxicated and there are no documented complications. Use it for acute effects from inhaled substances such as solvents, aerosols, or gases when the record does not name a more specific inhalant.
Clinical signs
Clinical features vary; refer to documentation. Common intoxication findings may include euphoria, disinhibition, dizziness, slurred speech, poor coordination, or altered mental status after inhalant exposure.
When to use this code
Use this code when the provider documents inhalant use with intoxication and does not describe delirium, psychosis, coma, or other complications. It also fits when the inhalant is unspecified and the encounter is for the acute intoxication state. If the note identifies a specific inhalant or another substance-related disorder, code that documentation instead.
Do not use for
Do not use it for inhalant dependence, withdrawal, or intoxication with complications. Also avoid it when the record names a different substance or a more specific inhalant-related diagnosis.
Coding tip
Verify that “intoxication” is explicitly documented and that no complication is present before assigning F18.920.
