D13.7 (Benign neoplasm of endocrine pancreas) compared with D49.0 (Neoplasm of unspecified behavior of digestive system), from the official CMS tabular data. D13.7 and D49.0 name the same anatomical site (insular tissue) with a different neoplasm behavior. MedCoder-derived
Same anatomical site, different neoplasm behavior.
Same site — unspecified behavior (insular tissue)
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.
