CPT® Code 70460

Computed tomography (CT), commonly known as a CT scan, is a diagnostic imaging procedure that utilizes advanced X-ray technology and computer processing to create detailed cross-sectional images of the head or brain. This procedure involves the use of specialized X-ray equipment that captures multiple images from various angles as the patient is positioned on a CT examination table. Initially, a preliminary scan is conducted to establish the starting position for the imaging process. During the actual CT scan, the examination table moves slowly through the scanner, while numerous X-ray beams and electronic detectors rotate around the area being examined. The system measures the amount of radiation absorbed by the tissues, which is crucial for generating accurate images. The data collected is then processed by a computer program, resulting in two-dimensional images that provide a comprehensive view of the internal structures of the head or brain. These images are displayed on a monitor for the physician's review. The physician may analyze the images in real-time and can request additional scans if specific areas require further investigation. It is important to note that CPT® Code 70460 is specifically used when intravenous contrast material is administered prior to the CT scan, enhancing the visibility of certain structures and abnormalities. In contrast, CPT® Code 70450 is designated for CT scans performed without contrast, while CPT® Code 70470 is applicable when a CT scan is initially conducted without contrast, followed by the administration of contrast for further imaging. The physician's interpretation of the CT findings is documented in a written report, which is essential for guiding further medical decisions.
