About J44.89
J44.89 is the ICD-10-CM diagnosis code for other specified chronic obstructive pulmonary disease. It belongs to category J44 (other chronic obstructive pulmonary disease), 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 J44.8, choose J44.89 (Other specified chronic obstructive pulmonary disease) only when documentation doesn't support a more specific option: bronchiolitis obliterans and bronchiolitis obliterans syndrome (J44.81).
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 was added in FY2024, effective October 1, 2023.
