Poisoning by oral contraceptives, undetermined, subs encntr

This code signifies a poisoning event involving oral contraceptives where the intent (accidental, intentional self-harm, assault, or therapeutic error) cannot be determined. It is used when a patient is receiving follow-up care for the effects of such a poisoning after the initial treatment.

Apply this code for subsequent encounters when a patient presents for ongoing management of symptoms or complications arising from an oral contraceptive poisoning of unknown intent. This includes situations like follow-up appointments for liver function monitoring, electrolyte imbalances, or other lingering effects.

• Ensure the documentation clearly states "undetermined" intent for the poisoning.
• This code is for subsequent encounters only; use the appropriate initial encounter code for the first visit.
• Always code any associated signs, symptoms, or adverse effects of the poisoning in addition to this code.
