C79.82 (Secondary malignant neoplasm of genital organs) compared with D28.0 (Benign neoplasm of vulva), from the official CMS tabular data. C79.82 and D28.0 name the same anatomical site (bartholin's gland) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (bartholin's gland)
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.
