ICD-10 Code C47.2 – Malignant neoplasm of peripheral nerves of lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C47.2 – Malignant neoplasm of peripheral nerves of lower limb, including hip
What it is
C47.2 identifies a malignant tumor arising from the peripheral nerves in the lower limb, including the hip region. Use it for documented cancer involving these nerves, not for benign nerve tumors or nonspecific soft tissue masses.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe a painful or enlarging mass, neurologic symptoms, or imaging and pathology confirming malignancy in a peripheral nerve of the lower limb.
When to use this code
Use C47.2 when the provider documents a malignant neoplasm of a peripheral nerve in the leg or hip area. It also fits confirmed primary or secondary malignant nerve involvement in that anatomic site, if the record is specific.
Do not use for
Do not use this code for benign peripheral nerve tumors, unspecified soft tissue cancers, or lesions outside the lower limb and hip. Check documentation if the site or malignant nature is unclear.
Coding tip
Code the most specific documented nerve site and laterality details elsewhere in the record when available.
