ICD-10 Code F18.229 – Inhalant Dependence with Intoxication, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.229 – Inhalant dependence with intoxication, unspecified
What it is
This code identifies inhalant dependence when the patient is currently intoxicated, but the specific inhalant is not documented. Use it for dependence involving inhaled substances such as solvents, aerosols, or gases when the record supports intoxication.
Clinical signs
Signs of intoxication may include euphoria, disinhibition, slurred speech, poor coordination, nystagmus, or altered mental status. Clinical features vary; refer to documentation for the specific presentation and substance details.
When to use this code
Use F18.229 when the provider documents inhalant dependence with current intoxication and does not name the inhalant. It fits encounters where the patient is actively impaired from inhalant use and the chart supports dependence. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for inhalant abuse, simple use without dependence, or intoxication without dependence. Do not assign it when the inhalant is specified and a more exact code is documented.
Coding tip
Confirm both dependence and intoxication are documented; if the inhalant is named, code the most specific valid option.
