D14.0 vs D38.5

D14.0 (Benign neoplasm of middle ear, nasal cavity and accessory sinuses) compared with D38.5 (Neoplasm of uncertain behavior of other respiratory organs), from the official CMS tabular data. D14.0 and D38.5 name the same anatomical site (antrum) with a different neoplasm behavior.

↔

D14.0

Benign neoplasm of middle ear, nasal cavity and accessory sinuses

Same anatomical site, different neoplasm behavior.

Same site — benign neoplasm (antrum)

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.
