C13.0 (Malignant neoplasm of postcricoid region) compared with D10.7 (Benign neoplasm of hypopharynx), from the official CMS tabular data. C13.0 and D10.7 name the same anatomical site (cricoid) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (cricoid)
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.
