Poisoning by antipruritics

This code indicates an adverse health effect resulting from the ingestion, exposure, or improper use of medications intended to relieve itching. It encompasses both accidental and intentional poisonings by substances like antihistamines, topical corticosteroids, or local anesthetics when used for antipruritic purposes. The patient presents with symptoms related to the toxic effects of these agents.

Assign this code when documentation clearly states poisoning or adverse effects due to antipruritic agents. This includes scenarios such as an overdose of diphenhydramine taken for itching, or systemic toxicity from excessive application of a topical corticosteroid. Supporting documentation should specify the substance involved and the nature of the poisoning.

• Always code the specific substance (E-code) responsible for the poisoning in addition to this code.
• Distinguish between poisoning (adverse effect due to incorrect use/overdose) and adverse effect in therapeutic use (correctly prescribed and administered).
• Review documentation for intent (accidental vs. intentional self-harm) to assign the appropriate E-code.
