Contact urticaria
ICD-10 L50.6 is a billable code used to indicate a diagnosis of contact urticaria.
Contact urticaria is a localized hypersensitivity reaction characterized by the development of wheals, erythema, and pruritus following direct contact with an allergen. The skin involved typically includes the area that has been exposed to the triggering substance, which can range from natural proteins (like those found in certain foods) to synthetic chemicals (such as those in cosmetics or cleaning products). The clinical presentation can vary from mild localized reactions to more severe systemic responses, depending on the individual's sensitivity and the nature of the allergen. Disease progression often involves the immediate onset of symptoms, usually within minutes to hours after exposure, and can resolve quickly once the allergen is removed. Diagnostic considerations include a thorough patient history, identification of potential allergens, and, in some cases, skin prick tests or patch testing to confirm sensitivities. It is essential for healthcare providers to differentiate contact urticaria from other forms of urticaria and dermatitis to ensure appropriate management and treatment.

L50.6 specifically covers contact urticaria, which can be triggered by various allergens including foods, medications, and environmental substances. It is important to document the specific allergen when applicable.
L50.6 should be used when the urticaria is directly linked to contact with an allergen, as opposed to other forms of urticaria that may not have a direct contact trigger.
Documentation should include a detailed history of exposure to potential allergens, the timing and nature of the reaction, and any diagnostic tests performed to confirm the allergen.
