ICD-10 Code F11.920 – Opioid use, unspecified with intoxication, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.920 – Opioid use, unspecified with intoxication, uncomplicated
What it is
Use this code for opioid use with current intoxication when the specific opioid is not documented and the episode is uncomplicated. It indicates acute opioid effects without delirium, coma, or other listed complications.
Clinical signs
Typical findings include opioid-related CNS depression, such as drowsiness, slowed speech, or impaired attention. Clinical features vary; refer to documentation for evidence of intoxication and absence of complications.
When to use this code
Assign this code when the record states opioid use with intoxication and does not identify a specific opioid. Use it only when the provider documents an uncomplicated intoxication state, not a more severe toxic effect or withdrawal picture.
If the chart mentions altered mental status or decreased alertness from opioids but lacks a more specific diagnosis, check documentation before coding. You should also confirm the episode is linked to opioid use rather than another substance.
Do not use for
Do not use this code for opioid dependence, abuse, or remission without intoxication. Also avoid it when the note documents delirium, coma, or another complication.
Coding tip
Match the code to the provider’s exact wording and verify that “unspecified” and “uncomplicated” are both supported.
