Opioid abuse with opioid-induced mood disorder

This code signifies a pattern of problematic opioid use leading to clinically significant impairment or distress, specifically characterized by the co-occurrence of a mood disorder directly induced by opioid use. The patient exhibits symptoms of both opioid abuse and a mood disturbance (e.g., depression, anxiety, bipolar-like symptoms) that developed during or within a month of opioid intoxication or withdrawal.

Apply this code when documentation clearly indicates a diagnosis of opioid abuse alongside a mood disorder that is determined to be substance-induced. This requires a causal link between opioid use and the mood disturbance, not merely a co-occurring independent mood disorder. Supporting documentation includes psychiatric evaluations, substance use assessments, and physician notes detailing the onset and nature of the mood symptoms in relation to opioid use.

• Ensure the documentation explicitly states the mood disorder is "opioid-induced" or "substance-induced" and not a pre-existing or independent condition.
• Do not use this code if the patient has opioid dependence (F11.2-) or if the mood disorder is not directly attributable to opioid use.
• Consider sequencing this code after any acute opioid intoxication or withdrawal codes if applicable, or as the primary diagnosis if it is the focus of the encounter.
