Neoplasm table relationship

C47.2
Malignant neoplasm of peripheral nerves of lower limb, including hip
D33.3
Benign neoplasm of cranial nerves

Same anatomical site, different neoplasm behavior.

Same site — benign neoplasm (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.
