Poisoning by antipruritics, undetermined, initial encounter

This code signifies an accidental or intentional exposure to an antipruritic medication, resulting in an adverse effect, where the intent of the poisoning cannot be determined. The patient is presenting for the initial treatment of this poisoning event.

Apply this code when a patient presents with symptoms of poisoning from an antipruritic agent, and the medical record does not clearly state whether the exposure was accidental or intentional. This is appropriate for the first encounter for this specific poisoning episode.

• Ensure documentation explicitly states "undetermined" intent for the poisoning.
• Do not use this code if the intent (accidental, intentional self-harm, assault) is clearly documented.
• Always sequence this code first, followed by codes for any associated manifestations or adverse effects.
