CPT® Code 73130

A radiologic examination of the hand, designated by CPT® Code 73130, involves the use of X-ray imaging to capture detailed images of the internal structures of the hand. This procedure employs indirect ionizing radiation, which is effective in visualizing non-uniform materials such as human tissue. The varying densities and compositions of the tissues allow certain X-rays to be absorbed while others pass through, resulting in a two-dimensional image that reveals the underlying anatomical features. The primary purpose of this examination is to identify various conditions affecting the hand, 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 provide insights into potential nutritional or metabolic disorders that may hinder proper growth and development. The examination typically includes a minimum of three views: the posteroanterior view, where the palm is placed flat down; lateral views, where the hand is positioned upright; and oblique views, which require the hand to be slightly rolled to capture different angles. Each of these views contributes to a comprehensive assessment of the hand's structure and any pathological conditions present.
