Irritant contact dermatitis, unspecified cause
ICD-10 L24.9 is a billable code used to indicate a diagnosis of irritant contact dermatitis, unspecified cause.
Irritant contact dermatitis (ICD-10 code L24.9) is a type of skin inflammation that occurs when the skin comes into contact with an irritant substance, leading to a localized reaction. Clinically, patients may present with symptoms such as redness, swelling, itching, and burning sensations in the affected area. The skin involved typically includes the epidermis and may extend to the dermis depending on the severity of exposure. Common irritants include soaps, detergents, solvents, and certain chemicals. Disease progression can vary; initial exposure may cause mild irritation, but repeated contact can lead to more severe dermatitis. Diagnostic considerations include a thorough patient history to identify potential irritants, physical examination of the skin, and, if necessary, patch testing to rule out allergic contact dermatitis. It is crucial to differentiate L24.9 from other dermatitis codes, such as allergic contact dermatitis (L23.9), to ensure accurate diagnosis and treatment.

L24.9 covers irritant contact dermatitis resulting from exposure to non-allergic irritants such as chemicals, soaps, and detergents. It does not include allergic reactions, which are coded separately under L23.9.
L24.9 should be used when the dermatitis is specifically due to irritants without an allergic component. If there is a known allergic reaction, L23.9 should be selected instead.
Documentation should include a detailed history of exposure to irritants, clinical findings from the physical examination, and any treatments attempted. Clear notes on the absence of allergic reactions are also necessary.
