Vibratory urticaria
ICD-10 L50.4 is a billable code used to indicate a diagnosis of vibratory urticaria.
Vibratory urticaria is a rare form of physical urticaria characterized by the development of wheals and pruritus following exposure to vibratory stimuli. Clinically, patients may present with localized or generalized hives that appear within minutes of exposure to vibrations, such as those from machinery, tools, or even vigorous exercise. The condition is thought to involve mast cell degranulation triggered by mechanical stimuli, leading to the release of histamine and other inflammatory mediators. The skin involved typically includes areas that are directly subjected to vibratory forces, often resulting in welts that can last from minutes to several hours. Disease progression can vary, with some patients experiencing recurrent episodes while others may develop chronic symptoms. Diagnostic considerations include a thorough patient history, physical examination, and possibly a provocation test to confirm the diagnosis. Differential diagnoses may include other forms of urticaria or dermatological conditions that present with similar symptoms. Understanding the patient's exposure history is crucial for effective management and treatment planning.

L50.4 specifically covers vibratory urticaria, which is characterized by wheals and itching following exposure to vibratory stimuli. It does not cover other forms of urticaria such as chronic spontaneous urticaria or physical urticaria due to heat or cold.
L50.4 should be used when the patient exhibits symptoms specifically triggered by vibratory stimuli. If the urticaria is due to other physical triggers or has no identifiable trigger, other codes under L50 should be considered.
Documentation should include a detailed patient history of symptoms, specific triggers related to vibratory exposure, results from any provocation tests, and treatment responses. This information is crucial for accurate coding and reimbursement.
