Poisoning by anthelminthics, undetermined, subs encntr

This code indicates a poisoning event due to an anthelminthic medication where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is receiving follow-up care for the effects of this poisoning after the initial treatment has been provided.

This code is appropriate for encounters where a patient is being seen for ongoing management or complications stemming from an anthelminthic poisoning of unknown intent. This includes situations like follow-up appointments for organ damage, persistent symptoms, or monitoring after discharge from acute care.

• Assign this code for any encounter after the initial treatment of the poisoning.
• Ensure documentation clearly states the poisoning was due to an anthelminthic and that the intent is undetermined.
• Always sequence this code after any codes for specific manifestations or complications of the poisoning.
