ICD-10 Code C47.11 – Malignant neoplasm of peripheral nerves of right upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C47.11 – Malignant neoplasm of peripheral nerves of right upper limb, including shoulder
What it is
This code identifies a malignant tumor arising from the peripheral nerves in the right upper limb, including the shoulder. Use it when documentation specifies cancer of a peripheral nerve in that anatomic site.
Clinical signs
Findings may include a palpable mass, pain, weakness, numbness, or other nerve-related deficits in the right arm or shoulder. Clinical features vary; refer to documentation.
When to use this code
Use C47.11 when the provider documents a malignant neoplasm of a peripheral nerve located in the right upper extremity or shoulder. It may also apply when pathology, imaging, or operative notes clearly localize the tumor to that site. Check documentation if the note only says “nerve tumor” or does not specify laterality.
Do not use for
Do not use this code for benign peripheral nerve tumors, unspecified nerve malignancies, or neoplasms outside the right upper limb. If the documentation does not confirm malignant behavior or exact location, check documentation.
Coding tip
Verify both malignancy and right-sided upper-limb/shoulder location before assigning C47.11.
