Code Description

ICD-10 Q33.4 is a billable code used to indicate a diagnosis of congenital bronchiectasis.

Key Diagnostic Point:

Congenital bronchiectasis is a rare respiratory condition characterized by the abnormal dilation of the bronchi, which can lead to chronic respiratory infections and impaired lung function. This condition is often associated with other congenital malformations of the respiratory system, such as choanal atresia, tracheoesophageal fistula, and lung hypoplasia. In infants, bronchiectasis may result from developmental anomalies that disrupt normal airway structure and function. The condition can manifest with symptoms such as chronic cough, wheezing, and recurrent pneumonia. Diagnosis typically involves imaging studies, such as chest X-rays or CT scans, which reveal the characteristic bronchial dilation. Management may include antibiotics for infections, airway clearance techniques, and in severe cases, surgical intervention. Understanding the underlying congenital factors is crucial for effective treatment and long-term management of affected children.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of bronchiectasis
  • Association with multiple congenital anomalies
  • Need for comprehensive documentation of respiratory symptoms
  • Potential for co-morbid conditions affecting coding

Audit Risk Factors

  • Inadequate documentation of associated congenital anomalies
  • Misclassification of bronchiectasis as acquired
  • Failure to document chronic respiratory symptoms
  • Inconsistent coding of related respiratory conditions
