Poisoning by drugs affecting uric acid metab, undet, subs

This code signifies an adverse effect from a medication intended to manage uric acid levels, where the intent (e.g., accidental, intentional self-harm) of the poisoning cannot be determined. This diagnosis is used when the patient is receiving follow-up care for the initial poisoning event.

Apply this code for patients presenting for ongoing treatment, monitoring, or evaluation of complications stemming from an indeterminate poisoning by drugs like allopurinol or febuxostat. This includes situations where the patient is stable but still requires medical attention related to the drug exposure.

• Ensure the encounter is for subsequent care, not the initial presentation of the poisoning.
• Confirm that the documentation explicitly states the intent of the poisoning is "undetermined."
• Always code an external cause code (e.g., Y92.-) in conjunction with this code to provide more context about the circumstances of the poisoning.
