ICD-10 Code F11.13 – Opioid Abuse with Withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.13 – Opioid abuse with withdrawal
What it is
F11.13 identifies opioid abuse when withdrawal symptoms are present. Use it when the record supports problematic opioid use and a current withdrawal state linked to that use.
Clinical signs
Withdrawal may include restlessness, anxiety, sweating, muscle aches, abdominal upset, yawning, or insomnia. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents opioid abuse and withdrawal in the same encounter. It fits cases where the patient has nondependent opioid misuse and signs consistent with withdrawal.
Check the note for terminology such as abuse, misuse, or harmful use, and confirm that withdrawal is explicitly documented. If the record instead describes dependence, use the appropriate dependence code.
Do not use for
Do not use it for opioid dependence with withdrawal or opioid intoxication. Also avoid it when withdrawal is not documented or when the substance is not an opioid.
Coding tip
Match the code to the provider’s exact wording and verify that abuse and withdrawal are both documented.
