ICD-10 Code F11.929 – Opioid use, unspecified with intoxication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.929 – Opioid use, unspecified with intoxication, unspecified
What it is
This code identifies opioid use with an intoxication state, but the opioid type and intoxication severity are not documented. Use it when the record supports opioid intoxication without further detail.
Clinical signs
Clinical features vary; refer to documentation. Typical intoxication findings may include sedation, impaired attention, slowed speech, or reduced coordination, but you should code only what is explicitly recorded.
When to use this code
Use F11.929 when the provider documents opioid use with intoxication and does not specify the opioid or the intoxication severity. It also fits cases where the note confirms intoxication but leaves the clinical description nonspecific.
If the chart later identifies a different opioid or a more specific intoxication category, update the code to match the final documentation. Check documentation for any coexisting dependence, abuse, or poisoning terms that may change code selection.
Do not use for
Do not use this code for opioid poisoning, overdose, or withdrawal. Also avoid it when the record documents a specific opioid or a more specific intoxication severity.
Coding tip
Code the documented level of detail exactly; unspecified terms should stay unspecified unless the provider adds clearer information.
