Opioid dependence with intoxication, unspecified

This diagnosis code signifies a patient's physiological and psychological reliance on opioids, accompanied by acute opioid intoxication. It indicates a state where the individual experiences the effects of recent opioid use, such as constricted pupils, drowsiness, or slurred speech, in the context of a sustained pattern of opioid use leading to dependence.

Apply this code when documentation clearly states opioid dependence and current intoxication, without specifying the severity of the intoxication. This is appropriate for patients presenting to the emergency department or an inpatient setting with symptoms of acute opioid poisoning who also have a history or current diagnosis of opioid dependence. Documentation should explicitly link the intoxication to opioid use and confirm the presence of dependence.

• Only use this code when the specific type or severity of intoxication is not documented. If mild, moderate, or severe intoxication is specified, a more precise code (F11.220, F11.221, F11.222) should be used.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Consider co-reporting with codes for withdrawal (F11.23-) if the patient is also experiencing withdrawal symptoms.
