An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note.

These malformations are present at birth and affect the trachea, or windpipe, or a bronchus. They belong to the broader group of respiratory system malformations.
The subdivisions separate windpipe conditions from bronchus conditions. Q32.0 names tracheomalacia, a windpipe malformation, while Q32.1 groups other windpipe malformations. For a bronchus, Q32.2 names bronchomalacia, Q32.3 identifies narrowing, and Q32.4 groups other malformations.
