Poisoning by unsp hormone antagonists, accidental, init

This code signifies an accidental overdose or adverse reaction to a medication that blocks the action of hormones, where the specific type of hormone antagonist is not identified. The patient's exposure was unintentional, and this encounter represents the initial phase of treatment for the poisoning.

Apply this code when a patient presents with symptoms of poisoning due to an unknown or unspecified hormone antagonist, and the event was clearly accidental. This is appropriate for the initial hospital visit or first encounter for treatment of the acute poisoning.

• Ensure the documentation explicitly states the poisoning was accidental and the specific hormone antagonist is not known.
• This code is for the initial encounter; subsequent care for the same poisoning would require a different seventh character.
• Always code any associated signs, symptoms, or manifestations of the poisoning in addition to this code.
