ICD-10 Code F11 – Opioid Related Disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11 – Opioid related disorders
What it is
F11 identifies opioid-related disorders, a group of conditions caused by opioid use, misuse, dependence, or other opioid-induced problems. Use it when the record documents an opioid-related clinical disorder rather than a single symptom.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include opioid misuse, dependence, intoxication, withdrawal, or opioid-induced mental or physical effects.
When to use this code
Use F11 when the clinician documents an opioid-related disorder as the diagnosis, such as opioid dependence or opioid-induced complications. It also fits when the chart clearly supports opioid misuse or other opioid-related clinical conditions. Check documentation for the specific subtype and any associated manifestations.
Do not use for
Do not use F11 for routine opioid therapy, a history of opioid use without current disorder, or pain treated with prescribed opioids alone. If the note does not support a disorder, check documentation.
Coding tip
Code the most specific F11 subcategory supported by the provider’s documentation and sequence any associated opioid-induced condition when instructed.
