ICD-10 Code F18.92 – Inhalant use, unspecified with intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.92 – Inhalant use, unspecified with intoxication
What it is
This code identifies inhalant use with current intoxication when the specific inhalant is not documented. It applies when the patient has acute effects from inhaling volatile substances, and the record does not specify the substance.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented signs of intoxication may include abnormal behavior, impaired coordination, slurred speech, or altered mental status after inhalant exposure.
When to use this code
Use this code when the note clearly states inhalant use with intoxication and does not name a more specific inhalant. It may fit emergency or urgent care records describing acute intoxication after inhaling fumes, aerosols, or solvents. You should code from the documented diagnosis, not from suspicion alone.
Do not use for
Do not use this code for inhalant use without intoxication, or when the record identifies a different substance class. If the documentation is vague, check documentation before assigning an unspecified intoxication code.
Coding tip
Query for the exact inhalant and whether intoxication is present when the chart is unclear.
