ICD-11 code : CA21;
Preferred Label : Emphysema;
ICD-11 definition : Emphysema is defined by abnormal and permanent enlargement of the airspaces that are
distal to the terminal bronchioles. This is accompanied by destruction of the airspace
walls, without obvious fibrosis (i.e. there is no fibrosis visible to the naked eye).
Emphysema can exist in individuals who do not have airflow obstruction; however, it
is more common among patients who have moderate or severe airflow obstruction.;
