Allergic contact dermatitis due to dyes
ICD-10 L23.4 is a billable code used to indicate a diagnosis of allergic contact dermatitis due to dyes.
Allergic contact dermatitis due to dyes is a localized inflammatory skin condition that arises when the skin comes into contact with specific allergens found in dyes. Clinically, it presents as erythema, pruritus, and vesicular lesions, typically occurring in areas where the dye was applied. The pathophysiology involves a Type IV hypersensitivity reaction, where sensitized T-cells react to the allergen upon re-exposure, leading to inflammation. The skin's anatomy involved includes the epidermis and dermis, where the inflammatory response manifests. Disease progression can vary; initial exposure may not elicit a reaction, but subsequent exposures can lead to significant dermatitis. Diagnosis is primarily clinical, supported by patient history and, if necessary, patch testing to identify the specific dye responsible. It is crucial to differentiate L23.4 from other dermatitis types, such as irritant contact dermatitis, to ensure appropriate management.

L23.4 specifically covers allergic contact dermatitis triggered by dyes, including hair dyes, fabric dyes, and other chemical dyes. It is characterized by a delayed hypersensitivity reaction, typically presenting with localized skin irritation and inflammation.
L23.4 should be used when the dermatitis is specifically due to dyes, as opposed to other allergens or irritants. If the dermatitis is due to a different substance, such as plants or metals, the appropriate L23 code should be selected.
Documentation should include a detailed patient history of exposure to dyes, clinical findings, and any results from patch testing that confirm the diagnosis of allergic contact dermatitis due to dyes.
