D28.7 (Benign neoplasm of other specified female genital organs) compared with D49.59 (Neoplasm of unspecified behavior of other genitourinary organ), from the official CMS tabular data. D28.7 and D49.59 name the same anatomical site (adnexa) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (adnexa)
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.
