Poisoning by anthelmintics

This code signifies an adverse reaction or toxic effect resulting from the ingestion, administration, or exposure to anthelmintic medications. These are drugs specifically designed to expel or destroy parasitic worms (helminths) from the body. The poisoning can manifest with various systemic symptoms depending on the specific drug and dosage.

Apply this code when documentation clearly indicates a patient is experiencing poisoning due to an anthelmintic agent. This includes accidental overdose, intentional self-harm, or adverse effects from therapeutic use. Supporting documentation should specify the anthelmintic involved and the resulting toxic manifestations.

• Always code the specific manifestation of the poisoning first, followed by this code as an E-code (E850.0-E869.9) to identify the drug.
• Distinguish between poisoning (adverse effect due to incorrect use/overdose) and adverse effect in therapeutic use (E930-E949).
• Review medication lists and patient history to confirm the anthelmintic as the causative agent.
