ICD-10 Code F18.11 – Inhalant abuse, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F18.11 – Inhalant abuse, in remission
What it is
F18.11 identifies a history of inhalant abuse that is currently in remission. Use it when the record shows the disorder is no longer active, but the diagnosis remains clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. In remission usually means there is no current evidence of active inhalant misuse, while the underlying substance use disorder remains part of the patient’s history.
When to use this code
Use this code when the provider documents inhalant abuse as “in remission,” “sustained remission,” or similar wording. It may apply during follow-up visits, behavioral health care, or history review when the disorder is not currently active.
Code it only when the chart clearly supports remission status. If the documentation instead describes current use, relapse, or unspecified substance misuse, check documentation before assigning F18.11.
Do not use for
Do not use this code for active inhalant abuse or for a general history of substance use without remission status. If the record is unclear, check documentation.
Coding tip
Look for explicit provider wording such as “in remission” before assigning F18.11.
