What This Code Means

Cancer that starts in the nerves of the left leg and hip area. This is a malignant tumor affecting the peripheral nerve tissue in this region.

Coding Tips

•Verify laterality is documented as left; if bilateral involvement exists, code both C47.21 and C47.22
•Distinguish from C47.1 (upper limb) and ensure the site includes hip/lower limb documentation

Clinical Significance

Malignant peripheral nerve sheath tumor of the left lower limb including hip is the laterality-specific code for left-sided involvement. Documentation of laterality is essential for surgical planning, radiation field delineation, and accurate risk adjustment coding.

Documentation Requirements

✓Left-sided laterality explicitly documented
✓Pathology confirming malignant nerve sheath tumor
✓Specific nerve and location within the left lower limb
✓Treatment plan and functional prognosis
✓Neurofibromatosis Type 1 status if applicable

Commonly Confused Codes

C47.20 (Unspecified lower limb) — use C47.22 when left is documented C47.21 (Right lower limb) — opposite laterality C49.22 (Soft tissue malignancy of left lower limb) — soft tissue origin, not nerve D36.13 (Benign neoplasm of peripheral nerves of lower limb) — benign counterpart
