ICD-10 Code F11.19 – Opioid abuse with unspecified opioid-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.19 – Opioid abuse with unspecified opioid-induced disorder
What it is
This code identifies opioid abuse when the record also shows an opioid-induced disorder, but the exact disorder is not specified. Use it when documentation confirms both abuse and a related opioid effect, yet the detail is incomplete.
Clinical signs
Clinical features vary; refer to documentation. Notes may mention behavioral misuse of opioids along with an opioid-related mental or physical disturbance, without naming the specific disorder.
When to use this code
Use F11.19 when the provider documents opioid abuse and an unspecified opioid-induced disorder in the same encounter. It fits cases where the opioid-related condition is clearly present, but the chart does not specify whether it is intoxication, delirium, mood disorder, or another defined entity.
If the record names a specific opioid-induced disorder, code that condition instead. Check documentation before assigning this code, especially when substance use is described without a confirmed disorder.
Do not use for
Do not use this code for uncomplicated opioid abuse without an induced disorder. Also avoid it when the documentation identifies a different substance or a more specific opioid-induced condition.
Coding tip
Look for both elements in the note: opioid abuse and an unspecified opioid-induced disorder; if either is missing, query or code more specifically.
