D10.39 (Benign neoplasm of other parts of mouth) compared with D37.04 (Neoplasm of uncertain behavior of the minor salivary glands), from the official CMS tabular data. D10.39 and D37.04 name the same anatomical site (salivary gland or duct) with a different neoplasm behavior. MedCoder-derived
Same anatomical site, different neoplasm behavior.
Same site — uncertain behavior (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.
