J98.1Pulmonary collapse

J98.1 is the ICD-10-CM diagnosis code for pulmonary collapse. It belongs to category J98 (other respiratory disorders), block J96-J99 (other diseases of the respiratory system) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within J98 (other respiratory disorders), J98.1 is specifically for pulmonary collapse. Related codes cover diseases of bronchus, not elsewhere classified (J98.0), interstitial emphysema (J98.2), Compensatory emphysema (J98.3), other disorders of lung (J98.4), diseases of mediastinum, not elsewhere classified (J98.5), disorders of diaphragm (J98.6), other specified respiratory disorders (J98.8) and respiratory disorder, unspecified (J98.9).

To report this condition, pick the subcode that matches the documentation: J98.11 (atelectasis) and J98.19 (collapse).

Don't report J98.1 together with the conditions in its Excludes1 note: therapeutic collapse of lung status (Z98.3).

Use an additional code to identify: exposure to environmental tobacco smoke (Z77.22), exposure to tobacco smoke in the perinatal period (P96.81), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
