Congenital stenosis of bronchus

This code identifies a narrowing of one or more bronchi present at birth. This congenital anomaly can restrict airflow to parts of the lung, potentially leading to respiratory distress, recurrent infections, or atelectasis. The stenosis can range from mild to severe, affecting a main bronchus or smaller segmental bronchi.

Assign this code when medical record documentation clearly indicates a diagnosis of congenital bronchial stenosis. This diagnosis is typically established through imaging studies such as bronchoscopy, CT scans, or MRI, and often presents with symptoms like wheezing, stridor, or recurrent pneumonia in infants or young children.

• Ensure the documentation specifies "congenital" to differentiate from acquired bronchial stenosis.
• Do not confuse with other congenital anomalies of the bronchus, such as bronchomalacia or tracheobronchial fistula.
• Code any associated respiratory symptoms or complications, such as recurrent pneumonia or atelectasis, as secondary diagnoses.
