About J84.0
J84.0 is the ICD-10-CM diagnosis code for alveolar and parieto-alveolar conditions. It belongs to category J84 (other interstitial pulmonary diseases), 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.
Within J84 (other interstitial pulmonary diseases), J84.0 is specifically for alveolar and parieto-alveolar conditions. Related codes cover with fibrosis (J84.1), lymphoid interstitial pneumonia (J84.2), other specified interstitial pulmonary diseases (J84.8) and interstitial pulmonary disease, unspecified (J84.9).
To report this condition, pick the subcode that matches the documentation: J84.01 (proteinosis), J84.02 (microlithiasis), J84.03 (hemosiderosis) and J84.09 (conditions).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
