C47.1Malignant neoplasm of peripheral nerves of upper limb, including shoulder

C47.1 is the ICD-10-CM diagnosis code for malignant neoplasm of peripheral nerves of upper limb, including shoulder. It belongs to category C47 (malignant neoplasm of peripheral nerves and autonomic nervous system), block C45-C49 (malignant neoplasms of mesothelial and soft tissue) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within C47 (malignant neoplasm of peripheral nerves and autonomic nervous system), C47.1 is specifically for malignant neoplasm of peripheral nerves of upper limb, including shoulder. Related codes cover peripheral nerves of head, face and neck (C47.0), peripheral nerves of lower limb, including hip (C47.2), peripheral nerves of thorax (C47.3), peripheral nerves of abdomen (C47.4), peripheral nerves of pelvis (C47.5), peripheral nerves of trunk, unspecified (C47.6), overlapping sites of peripheral nerves and autonomic nervous system (C47.8) and unspecified (C47.9).

To report this condition, pick the subcode that matches the documentation: C47.10 (shoulder), C47.11 (shoulder) and C47.12 (shoulder).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
