C47.0
Malignant neoplasm of peripheral nerves of head, face and neck
↔
D36.11
Benign neoplasm of peripheral nerves and autonomic nervous system of face, head, and neck

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.
