Poisoning by antiallerg/antiemetic, assault, init

This code signifies an intentional act of poisoning using antiallergic or antiemetic medications, where the patient is the victim of an assault. It specifically indicates the initial phase of treatment for such an event. The poisoning is not accidental or self-inflicted but rather inflicted by another party.

Apply this code when documentation clearly states a patient has been poisoned by antiallergic or antiemetic drugs as a result of an assault, and this is their first encounter for treatment of this specific poisoning. This would be used in emergency department visits or initial inpatient admissions following such an event.

• Always sequence this code after the primary diagnosis for the specific effects of the poisoning (e.g., nausea, respiratory depression).
• Ensure documentation explicitly states "assault" and identifies the substance as an antiallergic or antiemetic drug.
• Verify that this is indeed the "initial encounter" for treatment of this poisoning; subsequent encounters will require a different seventh character.
