About coding mucopurulent bronchitis
The ICD-10-CM code for mucopurulent bronchitis is J41.1 (Mucopurulent chronic bronchitis). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J41.1.
Within J41 (simple and mucopurulent chronic bronchitis), J41.1 is specifically for mucopurulent chronic bronchitis. Related codes cover simple chronic bronchitis (J41.0) and mixed simple and mucopurulent chronic bronchitis (J41.8).
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.
