CPT® Code 70488

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 body areas. In the case of CPT® Code 70488, the focus is on the maxillofacial area, which encompasses critical structures such as the forehead, sinuses, nose, nasal bones, and the upper and lower jaws (maxilla and mandible). Notably, the orbit, which houses the eye, is excluded from this examination. The procedure begins with the patient being positioned on a CT examination table, where an initial scan is conducted to establish the starting point for subsequent imaging. During the CT scan, the table moves slowly through the scanner while multiple X-ray beams and electronic detectors rotate around the targeted area. This rotation allows for the measurement of radiation absorption, which is crucial for generating accurate images. The data collected is processed by a computer, resulting in 2D cross-sectional images that are displayed on a monitor for the physician's review. The physician can assess these images in real-time and may request additional sections to enhance the detail of specific areas of interest. This procedure is particularly useful for diagnosing various conditions affecting the maxillofacial region. It is important to note that CPT® Code 70488 specifically refers to a CT scan performed initially without intravenous contrast material, followed by the administration of contrast material for further imaging, allowing for a more comprehensive evaluation of the area in question.
