CPT® Code 74178

Computed tomography, abdomen and pelvis; without contrast material in one or both body regions, followed by contrast material(s) and further sections in one or both body regions

Computed tomography (CT), commonly known as a CT scan, is a diagnostic imaging procedure that employs advanced X-ray technology and computer processing to generate detailed cross-sectional images of the abdomen and pelvis. This procedure is particularly valuable in visualizing internal structures, allowing for the assessment of various conditions affecting these body regions. During the CT scan, the patient is carefully positioned on a specialized examination table, which is then moved through the CT scanner. Initially, a preliminary scan is conducted to establish the optimal starting position for the imaging process. Following this, the CT scan is executed, where multiple X-ray beams are emitted and detected as they rotate around the abdomen and pelvis. The system measures the radiation absorption by different tissues, which is crucial for creating accurate images. The data collected during the scan is processed by a computer, resulting in two-dimensional images that provide a comprehensive view of the internal anatomy. Physicians can analyze these images in real-time and may request additional scans to focus on specific areas of interest. This particular CPT® code, 74178, is utilized when the CT scan is performed initially without the use of intravenous contrast material, followed by the administration of contrast material to enhance the imaging quality and allow for further detailed sections to be captured. The physician is responsible for reviewing the images, identifying any abnormalities, and documenting a formal interpretation of the findings for clinical use.
