ICD-10 Code C47.22 – Malignant neoplasm of peripheral nerves of left lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C47.22 – Malignant neoplasm of peripheral nerves of left lower limb, including hip
What it is
This code identifies a malignant tumor arising from the peripheral nerves in the left lower limb, including the hip. Use it when documentation specifies cancer of a peripheral nerve in that anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a localized mass, pain, numbness, weakness, or other nerve-related deficits in the left leg or hip region.
When to use this code
Use C47.22 when the provider documents a malignant neoplasm of a peripheral nerve in the left lower limb or hip. It also fits pathology, imaging, or operative reports that clearly identify that location and malignancy.
If the record only says “malignant peripheral nerve tumor” without laterality or site, check documentation before coding. Confirm that the lesion is primary to the peripheral nerve, not a metastasis or a different soft tissue tumor.
Do not use for
Do not use this code for benign nerve tumors, unspecified soft tissue cancers, or tumors of bones, joints, or skin. Check documentation if the malignancy is metastatic or the site is not clearly the left lower limb.
Coding tip
Verify both laterality and exact nerve location in the chart before assigning C47.22.
