Benign neoplasm of ribs, sternum, and clavicle

This code signifies the presence of a non-cancerous tumor originating in the bones of the chest wall or shoulder girdle, specifically the ribs, sternum, or clavicle. These are typically slow-growing masses that do not spread to other parts of the body.

Apply this code when documentation clearly identifies a benign neoplasm (e.g., osteochondroma, enchondroma, fibrous dysplasia) located in the ribs, sternum, or clavicle. This is appropriate for initial diagnosis, follow-up, or management of such a condition.

• Ensure the pathology report or physician documentation explicitly states "benign" and specifies one of the listed anatomical sites.
• Do not use this code for malignant neoplasms; refer to the 170 series for bone cancers.
• If the specific type of benign neoplasm is known, consider if a more specific ICD-9-CM code exists within the 213 category.
