About coding Bronchostenosis
The ICD-10-CM code for Bronchostenosis is J98.09 (Other diseases of bronchus, not elsewhere classified).
Within J98.0, choose J98.09 (Other diseases of bronchus, not elsewhere classified) only when documentation doesn't support a more specific option: acute bronchospasm (J98.01).
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.
