C47.10Malignant neoplasm of peripheral nerves of unspecified upper limb, including shoulder

C47.10 is the ICD-10-CM diagnosis code for malignant neoplasm of peripheral nerves of unspecified 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within C47.1, choose C47.10 (unspecified upper limb, including shoulder) only when documentation doesn't support a more specific option: right upper limb, including shoulder (C47.11) and left upper limb, including shoulder (C47.12).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 542 (Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with MCC, relative weight 1.7211), DRG 543 (Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with CC, relative weight 1.006) and DRG 544 (Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy without CC/MCC, relative weight 0.7406), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 171.2 (malignant neoplasm of connective and other soft tissue of upper limb, including shoulder).
