Poisoning by anthelminthics, assault, subsequent encounter

This code signifies a poisoning event resulting from the intentional administration of an anthelminthic medication to another person with the intent to cause harm. It specifically indicates that the patient is receiving follow-up care for the sequelae of this poisoning, such as ongoing treatment for organ damage or psychological effects.

Apply this code when documenting a patient presenting for continued management of health issues directly stemming from an anthelminthic poisoning that was inflicted as an act of assault. This includes situations where the patient is seen for medication adjustments, monitoring of long-term complications, or rehabilitation services after the initial acute phase of treatment.

• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning (e.g., liver failure, neurological damage).
• Ensure documentation clearly supports the "assault" intent and the "subsequent encounter" for ongoing care.
• Do not use for initial encounters or for accidental/unintentional poisonings.
