C32.3 (Malignant neoplasm of laryngeal cartilage) compared with D14.1 (Benign neoplasm of larynx), from the official CMS tabular data. C32.3 and D14.1 name the same anatomical site (arytenoid) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (arytenoid)
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.
