CPT® Code 71120

A radiologic examination of the sternum, identified by CPT® Code 71120, involves a diagnostic X-ray procedure specifically targeting the sternum, commonly known as the breastbone. This examination is conducted using a minimum of two distinct views to ensure comprehensive imaging of the sternum. The X-ray technique employs indirect ionizing radiation, which penetrates the body to create images of internal structures. The principle behind X-ray imaging relies on the varying densities and compositions of human tissues; as X-rays pass through the body, some are absorbed by denser materials, such as bones, while others pass through softer tissues. This differential absorption results in a two-dimensional representation of the anatomical structures, where bones typically appear white due to their density, and softer tissues and fluids are depicted in various shades of grey. Sternal X-rays are particularly valuable in clinical settings for diagnosing potential fractures, especially following trauma to the chest. Such trauma may arise from incidents like car accidents, sports injuries, assaults, or during resuscitation efforts. In cases where initial chest X-rays do not reveal any abnormalities, yet the patient continues to experience chest pain, a dedicated sternal X-ray can provide further insights. The physician interprets the resulting images to identify any fractures or other injuries that may not have been visible in preliminary imaging, thereby guiding appropriate treatment and management of the patient's condition.
