About J20.2

J20.2 is the ICD-10-CM diagnosis code for acute bronchitis due to streptococcus. It belongs to category J20 (acute bronchitis), block J20-J22 (other acute lower respiratory infections) 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 J20 (acute bronchitis), J20.2 is specifically for acute bronchitis due to streptococcus. Related codes cover due to Mycoplasma pneumoniae (J20.0), due to Hemophilus influenzae (J20.1), due to coxsackievirus (J20.3), due to parainfluenza virus (J20.4), due to respiratory syncytial virus (J20.5), due to rhinovirus (J20.6), due to echovirus (J20.7), due to other specified organisms (J20.8) 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 202 (Bronchitis and Asthma with CC/MCC, relative weight 0.9474) and DRG 203 (Bronchitis and Asthma without CC/MCC, relative weight 0.6512), 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 041.00 (streptococcus infection in conditions classified elsewhere and of unspecified site, streptococcus, unspecified) and 466.0 (acute bronchitis).
