Irritant contact dermatitis
Chapter 12:Diseases of the skin and subcutaneous tissue
ICD-10 L24 is a used to indicate a diagnosis of irritant contact dermatitis.
Irritant contact dermatitis (ICD-10 code L24) is a localized inflammatory skin condition resulting from direct contact with irritants such as chemicals, detergents, or physical agents. Clinically, it presents as erythema, edema, vesiculation, and crusting, often accompanied by pruritus. The affected areas typically include hands, forearms, and any skin that has been in contact with the irritant. The disease progression can vary from mild irritation to severe dermatitis, depending on the irritant's potency and duration of exposure. Diagnosis is primarily clinical, supported by a thorough patient history and physical examination. Patch testing may be utilized to rule out allergic contact dermatitis. It is crucial to differentiate L24 from other dermatitis types, such as allergic contact dermatitis (L23) and atopic dermatitis (L20), as treatment approaches differ significantly. Effective management includes identifying and avoiding the irritant, topical corticosteroids for inflammation, and emollients to restore skin barrier function.

L24 covers irritant contact dermatitis caused by various irritants, including soaps, solvents, and other chemicals. It does not include allergic reactions, which are classified under L23.
L24 should be used when the dermatitis is specifically due to irritant exposure without an allergic component. If there is an allergic reaction, L23 should be selected.
Documentation should include a detailed history of exposure to irritants, clinical findings such as the location and appearance of the rash, and any previous treatments attempted.
