D19.0 (Benign neoplasm of mesothelial tissue of pleura) compared with D38.2 (Neoplasm of uncertain behavior of pleura), from the official CMS tabular data. D19.0 and D38.2 name the same anatomical site (pleura) with a different neoplasm behavior. MedCoder-derived
Same anatomical site, different neoplasm behavior.
Same site — uncertain behavior (pleura)
The behavior documented for the site — malignant primary, secondary, carcinoma in situ, benign, uncertain or unspecified — decides which column of the neoplasm table, and therefore which code, applies.
