Poisoning by oth systemic anti-infect/parasit, assault, init

This code signifies a deliberate act of poisoning using a systemic anti-infective or antiparasitic medication not otherwise specified, resulting in an acute toxic reaction. The patient is experiencing the initial effects and treatment for this intentional exposure.

Apply this code when a patient presents with symptoms of poisoning due to the malicious administration of an anti-infective or antiparasitic drug. This includes situations like a victim being intentionally given an unknown or specified anti-infective agent by another person with harmful intent.

• Always use in conjunction with an external cause code (e.g., Y09.-) to fully describe the circumstances of the assault.
• Ensure the documentation clearly states the poisoning was an assault and that this is the initial encounter for treatment.
• Distinguish from accidental poisoning (T37.8X1-) or self-harm (T37.8X2-).
