Poisoning by peripheral vasodilators, assault, subs encntr

This code signifies a patient presenting for follow-up care or treatment of adverse effects resulting from an intentional overdose or malicious administration of a peripheral vasodilator. The poisoning was inflicted by another party with intent to harm.

Apply this code when documenting subsequent encounters for complications, ongoing treatment, or recovery from a peripheral vasodilator poisoning that was determined to be an assault. This includes follow-up appointments for organ damage, neurological sequelae, or psychological trauma directly related to the poisoning event.

• Requires an external cause code (X92-Y09) to fully describe the circumstances of the assault.
• Distinguish from accidental poisoning (T46.7X1-) or self-harm (T46.7X2-).
• Ensure documentation clearly states the intent of assault and that this is a subsequent encounter.
