Allergic urticaria
ICD-10 L50.0 is a billable code used to indicate a diagnosis of allergic urticaria.
Allergic urticaria, classified under ICD-10 code L50.0, is a skin condition characterized by the sudden onset of raised, itchy welts (hives) that can vary in size and shape. These lesions are typically caused by an allergic reaction to various triggers, including foods, medications, insect stings, or environmental factors. The underlying anatomy involved includes the dermis and epidermis, where mast cells release histamine and other inflammatory mediators, leading to vasodilation and increased vascular permeability. The disease can present acutely, with symptoms resolving within hours to days, or can become chronic, lasting for six weeks or longer. Diagnostic considerations include a thorough patient history to identify potential allergens, physical examination of the skin, and, if necessary, allergy testing to confirm specific sensitivities. Clinicians must differentiate allergic urticaria from other types of urticaria and dermatological conditions, such as chronic spontaneous urticaria or contact dermatitis, to ensure appropriate management and treatment.

L50.0 specifically covers allergic urticaria, which is triggered by allergens such as foods, medications, or environmental factors. It is characterized by the presence of wheals and pruritus.
L50.0 should be used when the urticaria is confirmed to be allergic in nature, as opposed to idiopathic or chronic spontaneous urticaria, which may require different management.
Documentation should include a detailed patient history identifying potential allergens, clinical findings from physical examinations, and results from any allergy testing performed.
