Opioid use, unspecified with intoxication delirium

This code signifies a patient's problematic pattern of opioid use that has led to clinically significant impairment or distress, without further specification of the severity or pattern of use. The patient is also experiencing delirium directly attributable to opioid intoxication.

Apply this code when documentation indicates opioid use disorder and the patient presents with acute delirium caused by recent opioid ingestion. This code is appropriate when the specific pattern of opioid use (e.g., mild, moderate, severe, in remission) is not documented.

• Ensure documentation clearly links the delirium to opioid intoxication.
• Do not use if the severity of the opioid use disorder is specified (e.g., mild, moderate, severe).
• Consider additional codes for any co-occurring physical or mental health conditions.
