About J82.8

J82.8 is the ICD-10-CM diagnosis code for 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 a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J82.81 (pneumonia), J82.82 (pneumonia), J82.83 (asthma) and J82.89 (classified).

It was added in FY2021, effective October 1, 2020.
