Poisn by anticoag antag, vit K and oth coag, assault, subs

This code signifies a poisoning event resulting from the intentional administration of anticoagulant antagonists, vitamin K, or other coagulants, with the intent to harm another individual. It specifically indicates that the patient is receiving follow-up care for the sequelae of this assault, rather than the initial acute treatment.

Apply this code when documenting a patient's subsequent visits for complications or ongoing management related to a poisoning by coagulants or their antagonists that occurred as an act of assault. This includes follow-up appointments for monitoring coagulation parameters, managing bleeding or clotting complications, or addressing other long-term effects.

• Always assign an external cause code (e.g., Y07.-) to further specify the assault.
• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating ongoing care after the initial treatment.
• Consider additional codes for specific symptoms, complications, or adverse effects resulting from the poisoning.
