CPT® Code 70490

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 specific areas within the body. In the case of CPT® Code 70490, the focus is on the soft tissues of the neck, and the procedure is performed without the use of contrast material. During the CT scan, the patient is carefully positioned on a specialized examination table designed for the CT scanner. An initial scan is conducted to establish the starting point for the imaging process. Following this, the CT scan is executed as the table gradually moves through the scanner. This movement allows multiple X-ray beams to be emitted and detected by electronic sensors that rotate around the neck region being examined. The system measures the varying levels of radiation absorption by the tissues, which is crucial for generating accurate images. The data collected during the scan is processed by a computer program, resulting in two-dimensional images that represent the soft tissues of the neck. 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 further detail is needed in specific areas of interest. The final step involves the physician interpreting the findings from the CT scan and documenting any abnormalities observed in a written report.
