CASE STUDY - Drug-induced delirium due to continuous opiate dependence; Which code is used?

• A. F11.20
• B. F11.29
• C. F11.21
• D. F12.20

Answer: (A)

Focus on how ICD-10-CM codes distinguish opioid use disorders by level of complication. When a patient has opioid dependence and there’s no explicit documentation of acute intoxication, withdrawal, or remission, the default code is opioid dependence, uncomplicated. That’s because the base diagnosis reflects the ongoing dependence without a specified complication. In this case, although delirium is noted as drug-induced, the documentation does not indicate an acute intoxication or withdrawal state tied to the delirium, nor does it specify remission. Therefore the appropriate single code is opioid dependence, uncomplicated. If the record had clear signs of intoxication or withdrawal, or if the delirium were explicitly documented as a separate, qualifying condition, different codes would be used to reflect those specifics.
