About coding pulmonary insufficiency

The ICD-10-CM code for pulmonary insufficiency is J98.4 (Other disorders of lung). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J98.4.

Within J98, choose J98.4 (Other disorders of lung) only when documentation doesn't support a more specific option: diseases of bronchus, not elsewhere classified (J98.0), pulmonary collapse (J98.1), interstitial emphysema (J98.2), Compensatory emphysema (J98.3), 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).

Don't report J98.4 together with the conditions in its Excludes1 note: acute interstitial pneumonitis (J84.114) and pulmonary insufficiency following surgery (J95.1-J95.2).

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.
