ICD-10 Code F11.1 – Opioid abuse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.1 – Opioid abuse
What it is
Use this code for harmful opioid use that does not meet criteria for dependence or a more specific opioid-related disorder. It identifies abuse of opioids such as prescription pain medicines or other opioid substances.
Clinical signs
Clinical features vary; refer to documentation. Common findings include recurrent opioid use despite harm, impaired control, and social or occupational problems linked to use.
When to use this code
Use F11.1 when the provider documents opioid abuse, opioid misuse, or harmful use without stating dependence. It may apply when the record describes repeated nonmedical use or continued use despite adverse consequences. Check documentation if the chart is unclear about abuse versus dependence.
Do not use for
Do not use this code for opioid dependence, opioid intoxication, or opioid withdrawal. If the provider documents another opioid-related disorder, code that condition instead.
Coding tip
Match the code to the provider’s exact wording and avoid assuming abuse when dependence is documented.
