D06.1 (Carcinoma in situ of exocervix) compared with D26.0 (Other benign neoplasm of cervix uteri), from the official CMS tabular data. D06.1 and D26.0 name the same anatomical site (cervix) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — benign neoplasm (cervix)
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.
