Congenital malformations of the respiratory system (Q30-Q34)

The ICD-10 codes Q30-Q34 cover congenital malformations of the respiratory system. These codes classify birth defects affecting the nose, larynx, trachea, bronchus, lungs, and related structures, used to record specific developmental abnormalities diagnosed in newborns or children.

The range includes Q30 for congenital nose malformations like choanal atresia (Q30.0), a blockage of the nasal passage, also known by terms such as nasal stenosis or congenital atresia of anterior nares. Codes Q31 handle larynx defects, including laryngeal web (Q31.0) and congenital laryngomalacia (Q31.5), which refer to tissue webs and floppiness in the larynx affecting breathing. Malformations of the trachea and bronchus fall under Q32, addressing issues such as tracheomalacia (Q32.0) or abnormal bronchial development. The Q33 series refers to lung malformations, including congenital cystic lung (Q33.0), lung agenesis (Q33.3), and bronchiectasis (Q33.4). Lastly, Q34 covers other congenital respiratory malformations like pleural anomalies and mediastinal cysts.

These codes help medical professionals document rare and complex respiratory birth defects using clinical terms and common synonyms. They are essential for accurate diagnosis, treatment planning, and health record documentation for congenital respiratory conditions.
