2026 ICD-10-CM Diagnosis Code F11.120 – Opioid abuse with intoxication, uncomplicated
What it is
This code identifies opioid abuse accompanied by intoxication, without documented complications. Use it when the record shows harmful opioid use and current intoxication, but no delirium, coma, or other specified complication.
Clinical signs
Clinical features vary; refer to documentation. Intoxication may include marked euphoria, drowsiness, slurred speech, impaired attention, or reduced coordination, with opioid misuse confirmed in the chart.
When to use this code
Use F11.120 when the provider documents opioid abuse and states the patient is intoxicated, but the episode is otherwise uncomplicated. It also fits notes describing acute opioid intoxication in a patient with abuse, when no additional intoxication-related disorder is recorded. Check documentation if dependence or poisoning is also mentioned.
Do not use for
Do not use this code for opioid dependence, opioid use without abuse, or opioid poisoning/overdose. If the note describes a complication such as delirium or coma, select the more specific code.
Coding tip
Code the highest documented specificity and verify whether the provider used abuse, dependence, or poisoning terminology.
