Urticaria, unspecified
ICD-10 L50.9 is a billable code used to indicate a diagnosis of urticaria, unspecified.
Urticaria, commonly known as hives, is a skin condition characterized by the sudden appearance of raised, itchy welts on the skin. These welts can vary in size and may appear anywhere on the body. The condition is often triggered by allergens, medications, infections, or stress, but in many cases, the exact cause remains unidentified. The skin involved in urticaria is primarily the dermis and epidermis, where mast cells release histamine and other chemicals, leading to vasodilation and increased vascular permeability. Disease progression can vary; acute urticaria lasts less than six weeks, while chronic urticaria persists for six weeks or longer. Diagnosis typically involves a thorough patient history, physical examination, and sometimes allergy testing to identify potential triggers. It is essential to differentiate urticaria from other skin conditions such as angioedema or eczema, which may require different management strategies. Treatment often includes antihistamines, corticosteroids, and avoidance of known triggers, with the goal of alleviating symptoms and preventing recurrence.

L50.9 covers unspecified urticaria, which may include acute and chronic forms without specific identification of the underlying cause. It does not cover allergic urticaria (L50.1) or other specific types.
L50.9 should be used when the specific type of urticaria is unknown or when the patient presents with urticaria symptoms without a clear diagnosis. If a specific cause is identified, a more specific code should be utilized.
Documentation should include a detailed patient history, description of symptoms, duration of the condition, and any identified triggers or treatments attempted. Allergy testing results, if performed, should also be included.
