D36.16 vs D48.2

D36.16 (Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis) compared with D48.2 (Neoplasm of uncertain behavior of peripheral nerves and autonomic nervous system), from the official CMS tabular data. D36.16 and D48.2 name the same anatomical site (lumbosacral plexus) with a different neoplasm behavior.

D36.16

Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis

↔

D48.2

Neoplasm of uncertain behavior of peripheral nerves and autonomic nervous system

Same anatomical site, different neoplasm behavior.

Same site — uncertain behavior (lumbosacral plexus)

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.
