Benign neoplasm of long bones of lower limb

This code signifies the presence of a non-cancerous tumor originating in the long bones of the leg, such as the femur, tibia, or fibula. These benign growths are typically slow-growing and do not metastasize to other parts of the body.

Apply this code when documentation confirms a benign neoplasm, such as an osteochondroma, enchondroma, or fibrous dysplasia, located specifically within a long bone of the lower extremity. Supporting documentation includes pathology reports confirming benignity and imaging studies (X-ray, MRI) identifying the lesion's location.

• Ensure the neoplasm is explicitly documented as benign; otherwise, consider codes for uncertain behavior or malignancy.
• Verify the anatomical site is a long bone of the lower limb; avoid using for benign neoplasms of flat bones or upper limbs.
• Do not use this code if the neoplasm is metastatic or secondary; refer to appropriate secondary malignancy codes.
