Poisoning by oth hormone antagonists, undetermined, subs

This code signifies a poisoning event involving an unspecified hormone antagonist, where the intent (accidental, intentional self-harm, assault, or undetermined) cannot be definitively established. It is used when a patient is receiving follow-up care for the sequelae or ongoing effects of such a poisoning.

Apply this code for patients presenting for subsequent treatment, monitoring, or evaluation of complications arising from a poisoning by an unidentifiable hormone antagonist, where the intent remains unknown. This includes situations like follow-up appointments for organ damage, persistent symptoms, or mental health support related to the initial event.

• Ensure documentation clearly states the encounter is for follow-up care of the poisoning.
• Only use this code when the specific hormone antagonist is not documented or cannot be classified elsewhere.
• Confirm the intent of the poisoning is explicitly noted as "undetermined" in the medical record.
