ICD-10 Code F18.19 – Inhalant abuse with unspecified inhalant-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.19 – Inhalant abuse with unspecified inhalant-induced disorder
What it is
This code identifies inhalant abuse when the record also shows an inhalant-related disorder, but the specific disorder is not named. Use it for harmful use of inhalants such as solvents, aerosols, or gases, when documentation is nonspecific.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include intoxication, confusion, dizziness, slurred speech, or other substance-related effects, but the exact inhalant-induced disorder must be documented.
When to use this code
Use F18.19 when the clinician documents inhalant abuse and an unspecified inhalant-induced disorder, or when the record clearly links the disorder to inhalant use but does not name the condition. This code fits encounters where the diagnosis is substance-related, yet details are limited.
Do not use for
Do not use this code for simple inhalant use without abuse, or when the chart identifies a different specific inhalant-induced disorder. Check documentation if the record names intoxication, delirium, or another distinct condition.
Coding tip
Code the inhalant-induced disorder only when the provider explicitly connects it to inhalant abuse; otherwise, query for clarification.
