J41.8Mixed simple and mucopurulent chronic bronchitis

J41.8 is the ICD-10-CM diagnosis code for mixed simple and mucopurulent chronic bronchitis. It belongs to category J41 (simple and mucopurulent chronic bronchitis), block J40-J4B (chronic lower respiratory diseases) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J41 (simple and mucopurulent chronic bronchitis), J41.8 is specifically for mixed simple and mucopurulent chronic bronchitis. Related codes cover simple chronic bronchitis (J41.0) and mucopurulent chronic bronchitis (J41.1).

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 190 (Chronic Obstructive Pulmonary Disease with MCC, relative weight 1.0748), DRG 191 (Chronic Obstructive Pulmonary Disease with CC, relative weight 0.8261) and DRG 192 (Chronic Obstructive Pulmonary Disease without CC/MCC, relative weight 0.6288), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 491.8 (other chronic bronchitis).
