Poisoning by antipruritics, undetermined, sequela

This code signifies a long-term health condition or complication arising from a past poisoning event involving antipruritic medications. The original poisoning's intent (accidental, intentional self-harm, assault) could not be determined at the time of the acute event. The current encounter is for managing the lasting effects of that prior exposure.

Apply this code when a patient presents with a chronic condition or residual symptom directly attributable to a previous, unclarified poisoning by an antipruritic agent. This is appropriate for follow-up care, rehabilitation, or ongoing management of sequelae that developed after the acute poisoning episode.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past antipruritic poisoning where the intent was unknown.
• Do not use for acute poisoning events; this code is exclusively for the long-term effects.
