J41Simple and mucopurulent chronic bronchitis

J41 is the ICD-10-CM diagnosis code for simple and mucopurulent chronic bronchitis. It belongs to block J40-J4B (chronic lower respiratory diseases) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J41.0 (bronchitis), J41.1 (bronchitis) and J41.8 (bronchitis).

The conditions in its Excludes2 note aren't part of J41, but may be coded alongside it if the patient has both: chronic bronchitis NOS (J42) and chronic obstructive bronchitis (J44.-).

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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
