Allergic contact dermatitis due to other chemical products
ICD-10 L23.5 is a billable code used to indicate a diagnosis of allergic contact dermatitis due to other chemical products.
Allergic contact dermatitis due to other chemical products is a type of skin inflammation that occurs when the skin comes into contact with specific chemicals that provoke an allergic reaction. Clinically, patients may present with erythema, pruritus, vesicles, and in severe cases, weeping lesions. The anatomy involved primarily includes the epidermis and dermis, where the immune response is triggered by allergens. Disease progression can vary; initial exposure may not elicit a reaction, but subsequent exposures often lead to sensitization and more pronounced symptoms. Diagnostic considerations include a thorough patient history, identifying potential allergens, and possibly conducting patch testing to confirm the specific chemical responsible for the dermatitis. It is crucial to differentiate L23.5 from other dermatitis codes, such as irritant contact dermatitis (L24) and other allergic dermatitis codes (L23.0-L23.4), to ensure accurate diagnosis and treatment.

L23.5 covers allergic contact dermatitis caused by various chemical products, including but not limited to fragrances, preservatives, and industrial chemicals. Diagnostic criteria include a history of exposure and clinical symptoms consistent with allergic dermatitis.
L23.5 should be used when the dermatitis is specifically due to an allergic reaction from chemical products, as opposed to irritant contact dermatitis (L24) or other allergic dermatitis codes, which may not specify the chemical trigger.
Documentation should include a detailed patient history of exposure to chemical products, clinical findings, and results from any allergy testing, such as patch tests, to substantiate the diagnosis.
