Opioid dependence with withdrawal

This diagnosis code signifies a patient's physiological and psychological reliance on opioid substances, accompanied by the presence of withdrawal symptoms when the opioid use is reduced or stopped. These symptoms can range from mild discomfort to severe and life-threatening conditions, indicating a significant disruption in the patient's physical and mental well-being due to opioid cessation.

Apply this code when documentation clearly indicates a diagnosis of opioid dependence and the patient is actively experiencing or has recently experienced withdrawal symptoms. This is appropriate for patients undergoing detoxification, those presenting to an emergency department with withdrawal, or during inpatient admissions where withdrawal management is a primary concern. Supporting documentation includes physician notes detailing withdrawal symptoms, clinical assessment tools (e.g., COWS scale), and a confirmed diagnosis of opioid dependence.

• Ensure documentation explicitly states both "opioid dependence" and the presence of "withdrawal symptoms."
• Do not code this with opioid dependence with intoxication (F11.22-) as per the Excludes1 note; these conditions are mutually exclusive.
• Consider sequencing this code as the primary diagnosis if the encounter's main reason is the management of opioid withdrawal.
