ICD-11 code : CB40.4;
Preferred Label : Compensatory emphysema;
ICD-11 definition : Compensatory emphysema is a condition in which one portion of the lung increases in
size and function, when another portion is destroyed or temporarily useless. It occurs,
for instance, in association with pneumonias, pleural effusions and pneumothorax.
Anatomically, there is found an enlargement of the normal lung; there are no variations
from the normal structure; the unaffected lung, as a result of distention, has an
increased vital capacity and is able to perform a greater amount of work than when
in its usual condition. The tissues show no similarity to those truly emphysematous.
This change is in no way related to true emphysema and the term should not be used,
as it creates great confusion in the literature. Its use is no more justified than
that of speaking of the compensatory enlargement of a kidney, when the opposite kidney
has been removed, as of a compensatory nephritis. True emphysema can never compensate
for diseased lung tissue, because the emphysematous lung is totally or almost totally
functionless.;
