Poisoning by anthelminthics, accidental, subs

This code signifies a poisoning event resulting from the accidental or unintentional ingestion or exposure to an anthelminthic medication. The patient is in the healing phase or receiving follow-up care for the initial poisoning. Anthelminthics are drugs used to treat parasitic worm infections.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of adverse effects stemming from an accidental anthelminthic poisoning. This includes follow-up appointments after initial emergency treatment, or when complications from the poisoning are being addressed.

• Always use an additional code to identify the specific anthelminthic drug, if known, from categories T36-T50.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Distinguish from initial encounters ("A") for acute poisoning or sequela ("S") for long-term complications.
