Congenital malformations of trachea and bronchus (Q32) ICD-10-CM
The Q32 code range covers congenital malformations of trachea and bronchus with 6 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q32 range.
Bronchomalacia
A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the BRONCHI. This results in a floppy bronchial wall making patency difficult to maintain. It is characterized by wheezing and difficult breathing.
Laryngomalacia
A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the LARYNX. This results in a floppy laryngeal wall making patency difficult to maintain.
Tracheobronchomalacia
A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the TRACHEA and the BRONCHI. This results in a floppy non-rigid airway making patency difficult to maintain.
Tracheomalacia
A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the TRACHEA. This results in a floppy tracheal wall making patency difficult to maintain. It is characterized by wheezing and difficult breathing.
About the Q32 Code Range
The ICD-10 code section Q32 covers congenital malformations of the trachea and bronchus, which are abnormalities present at birth affecting the airway structures. These codes identify specific conditions such as congenital tracheomalacia (Q32.0), other tracheal malformations (Q32.1), bronchomalacia (Q32.2), stenosis of the bronchus (Q32.3), and other bronchial malformations (Q32.4).
Medical coders assigning the ICD-10 code for congenital malformations of trachea and bronchus should distinguish among conditions like laryngotracheomalacia or congenital anomaly of tracheal cartilage (Q32.0), which relate to softening and collapse of tracheal walls, versus various forms of agenesis, stenosis, or fistula affecting the trachea or bronchus (Q32.1 and Q32.4). Congenital bronchomalacia (Q32.2) involves weakening of bronchial walls, while congenital stenosis of bronchus (Q32.3) refers to narrowing of these airways. Using these codes accurately facilitates recognition and treatment planning for infants with respiratory difficulties caused by these congenital airway anomalies.
