Poisoning by oth hormone antagonists, self-harm, init

This diagnosis indicates a patient has experienced an adverse effect from ingesting or administering a hormone antagonist, not otherwise specified, with the explicit intent of self-harm. This poisoning is acute and represents the initial presentation of the patient for this specific event.

Apply this code when documentation clearly states a patient intentionally overdosed on or misused a hormone antagonist (e.g., an antiandrogen, antiestrogen, or other endocrine-blocking agent not specified elsewhere) in a suicide attempt or act of self-mutilation. This code is appropriate for the emergency department visit or initial inpatient admission for managing the acute poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires clear documentation of "intentional self-harm" and the specific substance being a "hormone antagonist."
• Do not use for accidental poisonings or adverse effects from therapeutic use; those require different codes.
