ICD-10 Code F11.129 – Opioid Abuse with Intoxication, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.129 – Opioid abuse with intoxication, unspecified
What it is
Use this code for opioid abuse when the patient is intoxicated, but the specific opioid is not named. It indicates harmful opioid use with current intoxication symptoms.
Clinical signs
Typical findings include impaired judgment, drowsiness, euphoria, slowed thinking, or other intoxication features. Clinical features vary; refer to documentation.
When to use this code
Assign F11.129 when the record clearly documents opioid abuse and intoxication, but does not identify the opioid type. Use it when the provider links the intoxication to abuse rather than dependence or accidental exposure.
If the note only says opioid use without abuse or intoxication, check documentation before coding. You should also confirm whether a more specific opioid code is available.
Do not use for
Do not use this code for opioid dependence, poisoning, or uncomplicated opioid use. Check documentation if the chart describes overdose, withdrawal, or an unspecified opioid-related disorder.
Coding tip
Code the highest documented specificity, and verify that “abuse” and “intoxication” are both stated in the record.
