Poisoning by anthelminthics, assault, sequela

This code signifies a past event of intentional poisoning with an anthelminthic medication, administered by another person with malicious intent. It indicates that the patient is currently experiencing a residual condition or complication directly resulting from that assault. The anthelminthic agent was used for a purpose other than its intended therapeutic effect.

Apply this code when documenting a patient's current health status that is a direct consequence of a prior anthelminthic poisoning where the poisoning was an act of assault. This would be used for follow-up care, management of chronic complications, or when the sequela is the primary reason for the encounter, long after the acute poisoning event has passed.

• Always use in conjunction with a code describing the specific sequela (e.g., organ damage, neurological deficits).
• Ensure documentation clearly supports "assault" and "sequela" rather than accidental or self-harm poisoning.
• Verify the substance was an anthelminthic; do not use for other types of poisoning.
