Toxic effect of venom of hornets, assault, initial encounter

This code signifies a harmful systemic reaction resulting from the venom of a hornet sting, specifically when the sting was inflicted with malicious intent or as an act of violence. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of the poisoning.

Apply this code when a patient presents with symptoms of hornet venom toxicity (e.g., anaphylaxis, localized swelling, pain, nausea) and the medical record clearly documents that the sting was the result of an assault. This would include situations where a hornet's nest was intentionally thrown at or placed near the patient.

• Always confirm the intent of the hornet sting (assault vs. accidental) from the medical documentation.
• Remember to also code any specific signs or symptoms of the toxic effect, such as anaphylactic shock (T78.0-).
• Do not use this code for accidental hornet stings; refer to codes within the T63.451- or T63.452- series for those scenarios.
