ICD-11 code : CA26.0;
Preferred Label : Chronic obliterative bronchiolitis;
ICD-11 definition : Bronchiolitis obliterans is commonly used to describe a number of unrelated conditions
whose common end point is functional obstruction of bronchioles. A typical form is
constrictive bronchiolitis. Constrictive bronchiolitis is an uncommon histologic finding
characterized by alterations in the walls of membranous and respiratory bronchioles,
often without extensive changes in alveolar ducts and alveolar walls. These changes
lead to concentric narrowing or complete obliteration of the airway lumen. The clinical
manifestations of constrictive bronchiolitis usually include progressive airflow obstruction,
sometimes in the presence of a relatively normal chest radiograph. The clinical severity
depends upon the type, extent, and severity of the initial lung injury.;
