Brush Biopsy of the Lung
The term brush biopsy of the lung is actually a misnomer. The brush biopsy is of the bronchus, not the lung. The procedure is performed intrabronchially and samples are taken from within the bronchus and not the alveolar or lung tissue. Bronchial and/or lung brushings are not performed as an open procedure(s). This is different from a transbronchial biopsy where the bronchoscope biopsy forceps actually punctures the terminal bronchus and samples of the peribronchial alveoli (lung tissue) are taken. New notes have been added to biopsy code 33.24, Closed [endoscopic] biopsy of bronchus, and code 33.27, Closed...

Article Overview
This premium article reviews brush biopsy terminology for the bronchus versus the lung and places the procedure in the context of bronchoscopic sampling. It is aimed at coding professionals who need to interpret clinical documentation for respiratory biopsy procedures and understand the related coding notes discussed in the article.
Why This Topic Matters
Accurate interpretation of bronchoscopic biopsy documentation affects procedure coding and helps distinguish similar respiratory sampling techniques. The article also highlights coding note updates associated with related biopsy categories.
