ICD-10 Code F18.22 – Inhalant dependence with intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.22 – Inhalant dependence with intoxication
What it is
F18.22 identifies inhalant dependence when the patient is also intoxicated. Use it for ongoing inhalant use with current intoxication effects documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Intoxication may include behavioral changes, impaired coordination, altered judgment, slurred speech, or other acute CNS effects after inhalant use.
When to use this code
Use this code when the record clearly states inhalant dependence and intoxication together. It fits encounters where the provider documents current intoxication related to inhalant use, not just past use or dependence alone.
If the note only says inhalant abuse, use a different code. If intoxication is present but dependence is not documented, check documentation before coding F18.22.
Do not use for
Do not use for inhalant use without dependence, or for dependence without intoxication. Do not assume intoxication from history alone; the record must support it.
Coding tip
Confirm both dependence and intoxication are explicitly documented before assigning F18.22.
