C25.3 (Malignant neoplasm of pancreatic duct) compared with D01.7 (Carcinoma in situ of other specified digestive organs), from the official CMS tabular data. C25.3 and D01.7 name the same anatomical site (pancreas) with a different neoplasm behavior.
Same anatomical site, different neoplasm behavior.
Same site — carcinoma in situ (pancreas)
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.
