Malignant neoplasm of right upper limb

This code signifies a primary cancerous tumor originating in the tissues of the right upper extremity, encompassing structures from the shoulder to the hand. It indicates a malignant growth that has not metastasized from another site.

Assign this code when documentation confirms a primary malignant neoplasm located specifically in the right upper limb. This typically applies to diagnoses such as osteosarcoma, chondrosarcoma, or soft tissue sarcomas of the arm, forearm, or hand.

• Ensure the documentation clearly specifies "primary" malignancy and the "right" upper limb.
• Do not use for secondary (metastatic) neoplasms; refer to codes in the C79 series for those.
• Be specific regarding the exact anatomical site within the upper limb if further detail is available (e.g., C40.01 for long bones of right upper limb).
