ICD-10 Code F18.129 – Inhalant abuse with intoxication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.129 – Inhalant abuse with intoxication, unspecified
What it is
This code identifies inhalant abuse with current intoxication when the specific inhaled substance is not documented. It applies when the patient has used an inhalant and shows acute intoxication effects.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include recent inhalant use with impaired judgment, altered behavior, euphoria, dizziness, confusion, or other intoxication signs.
When to use this code
Use this code when the record states inhalant abuse and intoxication, but does not name a more specific inhalant. It also fits when the clinician documents intoxication from inhalant misuse without further detail. Check documentation if the substance, pattern, or intent is unclear.
Do not use for
Do not use this code for inhalant use without intoxication, or when the record describes dependence, remission, or another substance category. If the documentation names a different inhalant-related disorder, code that condition instead.
Coding tip
Confirm both abuse and intoxication are documented; if either element is missing, this code may not be appropriate.
