C47.4

Malignant neoplasm of peripheral nerves of abdomen

↔

D48.2

Neoplasm of uncertain behavior of peripheral nerves and autonomic nervous system

Same anatomical site, different neoplasm behavior.

Same site — uncertain behavior (nerve)

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.
