Poisoning by local astringents/detergents, undet, init

This code signifies a poisoning event involving local astringents or detergents where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is in the initial phase of treatment for the toxic effects.

Apply this code when a patient presents with symptoms of poisoning from substances like witch hazel, rubbing alcohol (used topically), or common household cleaning detergents, and the medical record does not specify whether the exposure was accidental or intentional. This code is appropriate for the first encounter for this specific poisoning event.

• Requires documentation of "undetermined" intent for the poisoning.
• Always assign a secondary code for the specific manifestation of the poisoning (e.g., chemical burns, dermatitis).
• Ensure the "A" seventh character is used only for the initial encounter for this poisoning.
