About coding acquired mounier-kuhn syndrome
The ICD-10-CM code for acquired mounier-kuhn syndrome is J98.09 (Other diseases of bronchus, not elsewhere classified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J98.09.
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.
