ICD-10 Code F11.12 – Opioid Abuse with Intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.12 – Opioid abuse with intoxication
What it is
This code identifies opioid abuse accompanied by intoxication, meaning harmful opioid use with current intoxication effects. Use it when the record supports both abuse and intoxication.
Clinical signs
Typical findings include impaired attention, sedation, slowed speech, and decreased coordination. Clinical features vary; refer to documentation for the specific intoxication presentation.
When to use this code
Use F11.12 when the provider documents opioid abuse and notes intoxication at the same encounter. It may fit emergency, inpatient, or outpatient records describing acute opioid-related impairment. If the chart does not clearly state abuse, intoxication, or both, check documentation.
Do not use for
Do not use this code for opioid dependence, opioid use without abuse, or opioid withdrawal alone. If the record only says overdose or poisoning, choose the appropriate poisoning code instead.
Coding tip
Code the documented combination of abuse and intoxication only when both are clearly supported in the note.
