Benign neoplasm of short bones of lower limb

This code signifies the presence of a non-cancerous tumor originating in the short bones of the lower extremity. These benign growths are typically slow-growing and do not metastasize to other parts of the body. Examples include osteochondromas or enchondromas affecting bones like the tarsals or metatarsals.

Apply this code when documentation confirms a benign neoplasm located specifically within the short bones of the lower limb, such as the foot. This diagnosis is typically supported by imaging studies (X-ray, MRI) and often a biopsy confirming benign histology. Use when the patient presents with symptoms related to the mass or it is an incidental finding.

• Ensure the documentation specifies "benign" and clearly identifies the affected bone as a "short bone" of the lower limb.
• Distinguish from benign neoplasms of long bones (e.g., femur, tibia) or other bone types.
• Do not use for malignant neoplasms; those require codes from the 170 series.
