About coding airway obstruction
The ICD-10-CM code for airway obstruction is J98.8 (Other specified respiratory disorders). The official index lists 15 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J98.8.
Within J98, choose J98.8 (Other specified respiratory disorders) 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), other disorders of lung (J98.4), diseases of mediastinum, not elsewhere classified (J98.5), disorders of diaphragm (J98.6) and respiratory disorder, unspecified (J98.9).
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 is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
