Poisoning by enzymes, assault, initial encounter

This code signifies a deliberate act of harm involving the administration or exposure to enzymes, resulting in a toxic reaction or adverse effect. This could involve the intentional use of enzymes as a weapon or in a malicious manner, leading to a poisoning event. The "initial encounter" indicates that the patient is receiving active treatment for this specific poisoning.

This code is appropriate when a patient presents with symptoms of enzyme poisoning, and a thorough investigation confirms that the exposure was due to an intentional act of assault. Examples include a patient who was forcibly injected with an enzyme or had enzymes covertly added to their food or drink with malicious intent. It should be used for the first time the patient is seen for this particular poisoning event.

• Always ensure documentation clearly specifies the intent as "assault" and not accidental or therapeutic misadventure.
• Pair this code with external cause codes (e.g., Y07.-) to fully describe the circumstances of the assault.
• Confirm that the encounter is indeed the initial treatment for this specific poisoning episode. Subsequent encounters would use a different seventh character.
