Benign neoplasm of long bones of right lower limb

This code signifies the presence of a non-malignant tumor originating in the long bones of the patient's right leg. These benign growths are typically slow-growing and do not metastasize, but may cause pain, swelling, or functional impairment depending on their size and location.

Apply this code when documentation clearly indicates a benign neoplasm (e.g., osteochondroma, enchondroma, fibrous dysplasia) affecting the femur, tibia, or fibula of the right lower limb. Supporting documentation should include pathology reports confirming benignity or imaging studies consistent with a benign bone tumor.

• Ensure laterality is explicitly documented as "right" lower limb; otherwise, an unspecified laterality code may be necessary.
• Distinguish carefully between benign and malignant bone tumors; malignant tumors of bone have different code ranges (C40-C41).
• Do not use this code for benign neoplasms of joints, cartilage, or other connective tissues, which have separate classifications.
