CPT® Code 70380

The CPT® Code 70380 refers to a radiologic examination specifically targeting the salivary glands to identify the presence of calculi, commonly known as stones. These stones, or sialoliths, can form within the salivary glands or their ducts and are typically radiopaque, meaning they can be visualized on diagnostic imaging due to their density. The examination is performed using X-ray technology, which employs indirect ionizing radiation to create images of the internal structures of the body. The X-ray process is effective because it interacts differently with various materials, such as human tissue, based on their density and composition. This differential absorption allows for the creation of a two-dimensional image that highlights the anatomical features of the salivary glands. During the procedure, various views may be captured, including panoramic and occlusal images. A panoramic view provides a comprehensive image of the entire extraoral jaw and facial area, while an occlusal view focuses on the submandibular spaces within the mouth. The resulting images are then analyzed by the physician to locate any suspected stones, which may require further intervention for removal.
