CPT® Code 73120

A radiologic examination of the hand, designated by CPT® Code 73120, involves the use of X-ray imaging to capture detailed images of the internal structures of the hand. This procedure utilizes indirect ionizing radiation, which interacts with the varying densities and compositions of human tissue. As X-rays pass through the hand, some are absorbed while others are transmitted, allowing for the creation of a two-dimensional image on a detector. The resulting radiographs are essential for diagnosing a variety of conditions, including fractures, dislocations, deformities, degenerative bone diseases, osteomyelitis, arthritis, foreign bodies, and tumors. Additionally, hand X-rays are instrumental in assessing the 'bone age' of pediatric patients, which can help identify potential nutritional or metabolic disorders that may affect normal growth and development. The examination typically includes two views: a posteroanterior view, where the palm is placed flat against the film, and a lateral view, where the hand is positioned upright on the ulnar side. Oblique views may also be obtained to provide further detail, with the hand slightly rolled to capture different angles. This comprehensive imaging approach ensures that a thorough evaluation of the hand's anatomy and any pathological conditions can be achieved.
