C47.3

Malignant neoplasm of peripheral nerves of thorax

↔

D36.14

Benign neoplasm of peripheral nerves and autonomic nervous system of thorax

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.
