C47.5 vs D36.16

C47.5 (Malignant neoplasm of peripheral nerves of pelvis) compared with D36.16 (Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis), from the official CMS tabular data. C47.5 and D36.16 name the same anatomical site (lumbosacral plexus) with a different neoplasm behavior. MedCoder-derived

C47.5

Malignant neoplasm of peripheral nerves of pelvis

↔

D36.16

Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis

Same anatomical site, different neoplasm behavior.

Same site — benign neoplasm (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.

Can these codes be reported together?

Same site, different neoplasm behavior. C47.5 and D36.16 name the same anatomical site (lumbosacral plexus) with a different neoplasm behavior.

From the CMS/CDC Table of Neoplasms: the behavior documented for that site — malignant primary, secondary, carcinoma in situ, benign, uncertain or unspecified — decides which column, and therefore which code, applies.
