Poisoning by oth hormone antagonists, accidental, init

This code signifies an unintentional adverse event resulting from the ingestion or exposure to a hormone antagonist medication, other than those specifically classified elsewhere. It indicates that the patient's body has been negatively affected by the substance, leading to signs and symptoms of poisoning. This category encompasses a broad range of pharmaceutical agents that block or inhibit hormone action.

Apply this code when a patient presents with an acute poisoning due to an accidental overdose or misadministration of a hormone antagonist. This includes scenarios where a patient mistakenly takes the wrong medication, an incorrect dose, or is unintentionally exposed to the substance. It is appropriate for the initial encounter for treatment of this poisoning event.

• Ensure the poisoning is explicitly documented as accidental or unintentional by the provider.
• Verify the substance is indeed a hormone antagonist and not a hormone itself or another class of medication.
• Confirm this is the initial encounter for the poisoning; subsequent encounters will require different seventh characters.
