CPT® Code 73030

A radiologic examination of the shoulder, designated by CPT® Code 73030, involves obtaining a complete assessment through a minimum of two distinct views. The shoulder is anatomically defined as the junction between the humeral head and the glenoid cavity of the scapula. This examination typically includes standard views such as the anteroposterior (AP) view, which provides a frontal perspective of the shoulder, and the lateral 'Y' view, which is characterized by the Y shape formed by the scapula when viewed from the side. In certain cases, an axial view may also be acquired, particularly when the patient is capable of positioning their arm in abduction, allowing for a more comprehensive evaluation of the shoulder joint. The process of X-ray imaging utilizes indirect ionizing radiation to capture images of the internal structures of the body. X-rays are effective on non-uniform materials, such as human tissue, due to the varying densities and compositions present. This differential absorption allows some X-rays to penetrate and pass through the body, while others are absorbed, resulting in a two-dimensional image that reveals the underlying anatomical structures. For coding purposes, CPT® Code 73020 is applicable for a single view, whereas CPT® Code 73030 is specifically used when a complete examination is performed with at least two views.
