J82Pulmonary eosinophilia, not elsewhere classified

J82 is the ICD-10-CM diagnosis code for pulmonary eosinophilia, not elsewhere classified. It belongs to 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 1 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J82.8 (classified).

The conditions in its Excludes2 note aren't part of J82, but may be coded alongside it if the patient has both: pulmonary eosinophilia due to aspergillosis (B44.-), pulmonary eosinophilia due to drugs (J70.2-J70.4), pulmonary eosinophilia due to specified parasitic infection (B50-B83), pulmonary eosinophilia due to systemic connective tissue disorders (M30-M36) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 518.3 (pulmonary eosinophilia).
