Poisoning by dental drugs, topically applied, assault, init

This code signifies an intentional act of harm involving the administration of a dental drug, specifically one applied to the surface of the body (e.g., gums, skin), resulting in a toxic reaction. The poisoning is a direct consequence of an assault, meaning it was inflicted by another person with malicious intent. This initial encounter indicates the patient is receiving active treatment for the acute effects of the poisoning.

Apply this code when documenting a patient presenting with symptoms of poisoning due to a topically applied dental drug, and the medical record clearly states the poisoning was a result of an assault. This would include scenarios where a dental anesthetic or other dental topical agent was forcibly or deceptively applied to cause harm. Use for the initial visit where the poisoning is first diagnosed and treated.

• Ensure documentation explicitly states "assault" as the cause of poisoning.
• Verify the drug was a "dental drug" and "topically applied."
• Always use the 7th character "A" for the initial encounter when the patient is receiving active treatment.
