Adverse effect of local astringents/detergents, init

This diagnosis code signifies an unintended and harmful reaction experienced by a patient due to the therapeutic use of topical astringents or detergents. These substances are typically applied to the skin or mucous membranes for their drying, constricting, or cleansing properties, and an adverse effect indicates a negative outcome rather than an overdose or poisoning.

Use this code when a patient presents with symptoms such as skin irritation, allergic contact dermatitis, excessive dryness, or other localized adverse reactions following the proper application of a local astringent (e.g., witch hazel, aluminum chloride) or a local detergent (e.g., certain soaps, cleansers). This applies when the substance was used as prescribed or intended, and the reaction is an undesirable side effect.

• Ensure documentation clearly states the substance was used therapeutically and the reaction was adverse, not a poisoning.
• Always assign an additional code to specify the nature of the adverse effect (e.g., dermatitis, rash).
• The "A" seventh character indicates an initial encounter for treatment of the adverse effect.
