ICD-9-CMThis code represents acute laryngotracheobronchitis, a common respiratory infection in young children characterized by inflammation of the larynx, trachea, and bronchi. It typically presents with a distinctive barking cough, stridor, and hoarseness due to airway narrowing.
Use this code for documented cases of croup, often viral in origin, presenting with the characteristic symptoms. This diagnosis is typically made clinically based on the patient's age, symptoms, and physical examination findings.
