Benign neoplasm of long bones of left lower limb

This code identifies a non-cancerous tumor originating in the long bones of the patient's left lower extremity. These benign growths are typically slow-growing and do not metastasize, but can cause pain, swelling, or pathological fractures depending on their size and location.

Apply this code when documentation specifies a benign neoplasm, such as an osteochondroma, enchondroma, or non-ossifying fibroma, located in a long bone of the left femur, tibia, or fibula. Supporting documentation should clearly state the benign nature of the lesion and its specific anatomical location.

• Ensure the documentation explicitly states "benign" and specifies the "left lower limb" and "long bone."
• Do not use this code for malignant neoplasms; refer to the C-codes for cancerous tumors.
• Distinguish between long bones (e.g., femur, tibia, fibula) and other bones of the lower limb (e.g., patella, tarsals, metatarsals) to ensure accurate site specificity.
