Organizing pneumonia (OP)

unclassifiable ILD indicates two or more ILD diagnoses remained under consideration or ILD remained unclassifiable.

†

unclassifiable fibrosis indicates histologic findings of pulmonary fibrosis were present, but more specific histopathologic patterns of fibrosis were absent.
