About J82.89
J82.89 is the ICD-10-CM diagnosis code for other pulmonary eosinophilia, not elsewhere classified. It belongs to category J82 (pulmonary eosinophilia, not elsewhere classified), block J80-J84 (other respiratory diseases principally affecting the interstitium) 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 J82.8, choose J82.89 (Other pulmonary eosinophilia, not elsewhere classified) only when documentation doesn't support a more specific option: chronic eosinophilic pneumonia (J82.81), acute eosinophilic pneumonia (J82.82) and eosinophilic asthma (J82.83).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), 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 FY2021, effective October 1, 2020.
