D07.69 (Carcinoma in situ of other male genital organs) compared with D40.1 (Neoplasm of uncertain behavior of testis), from the official CMS tabular data. D07.69 and D40.1 name the same anatomical site (testis) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — uncertain behavior (testis)
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.
