C79.89 (Secondary malignant neoplasm of other specified sites) compared with D11.7 (Benign neoplasm of other major salivary glands), from the official CMS tabular data. C79.89 and D11.7 name the same anatomical site (salivary gland or duct) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (salivary gland or duct)
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.
