Poisoning by unsp hormone antagonists, self-harm, init

This code signifies a patient presenting with adverse effects from intentionally self-administering an unknown or unspecified hormone antagonist. The poisoning is a result of a deliberate act to harm oneself, and this encounter represents the initial treatment for this event.

This code is appropriate for documenting the first visit for a patient who has overdosed on a hormone antagonist, where the specific agent is not yet identified or documented. It should be used when the medical record clearly indicates the poisoning was a suicide attempt or other form of intentional self-harm.

• Ensure documentation explicitly states "intentional self-harm" or "suicide attempt" to support this intent.
• Only use this code for the initial encounter of treatment for this specific poisoning event.
• Avoid using this code if the specific hormone antagonist is known; instead, code to the more specific T38.91-T38.99 series.
