Poisoning by antipruritics, undetermined, subs encntr

This code signifies an adverse event resulting from exposure to an antipruritic medication, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is receiving follow-up care for the sequelae of this poisoning after initial treatment.

Apply this code when a patient presents for ongoing management of symptoms or complications stemming from an antipruritic poisoning, and the circumstances surrounding the exposure remain unclear. This is appropriate for visits after the initial acute phase of treatment.

• Always sequence this code after the primary diagnosis indicating the specific manifestation of the poisoning.
• Ensure documentation clearly states the encounter is for follow-up care and the intent of the poisoning is undetermined.
• Do not use for initial encounters or for poisonings where the intent is known (e.g., accidental, intentional).
