Carotid Angiography Codeįor the codes concerning carotid imaging, the work of the lower-numbered codes is included in the higher-numbered codes. Let’s look at our hierarchy in a different way – even though the primary codes are in the same series, we can view this as two hierarchies based on what’s being imaged. So, what’s different with this code set? It depends on what’s being imaged. This is true with this series of codes…to a point. The common mistake specific to this code set comes from thinking within the hierarchical logic we are accustomed to: the lower-numbered code(s) in the series are all valued into the higher-numbered code(s) in the series and submitting two codes from the same series would be incorrect. Like other code sets, these codes are built on a hierarchy, meaning the lower-numbered codes are valued into the higher-numbered codes. For some CT exams, a contrast material is used to enhance visibility in the area of the body being studied.The concept behind bundled codes is not new to anyone familiar with coding for interventional radiology procedures, and it’s no surprise that complete codes (including catheterization and imaging) exist for arch, carotid and vertebral angiography– CPT® codes 36221-36228. For children, the CT scanner technique will be adjusted to reduce the radiation dose. Such speed is beneficial for all patients but especially children, the elderly and critically ill. Our scanners are so fast that they can scan through large sections of the body in just a few seconds. The CT scanners at our offices are multidetector scanners, allowing thinner slices to be obtained in a shorter period of time, resulting in more detail and additional view capabilities. This technique is called helical or spiral CT. A special computer program processes this large volume of data to create two-dimensional cross-sectional images of the body, which are then displayed on a monitor. At the same time, the examination table is moving through the scanner, so that the x-ray beam follows a spiral path. With CT scanning, numerous x-ray beams and a set of electronic x-ray detectors rotate around the patient, measuring the amount of radiation being absorbed throughout his/her body. Bones appear white on the xray soft tissue shows up in shades of gray and air appears black. In a conventional x-ray exam, a small burst of radiation is aimed at and passes through the body, recording an image on photographic film or a special image recording plate. Different body parts absorb the x-rays in varying degrees. In many ways CT scanning works very much like other x-ray examinations. At our offices, our CT scanners adjust the radiation dose for each patient to use the lowest possible dose. There has been considerable work done recently on radiation dose from CT scans. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and musculoskeletal disorders. CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams. They also can be printed or transferred to a CD. These cross-sectional images are then examined on a computer monitor by a radiologist. General Information about CT Scanning What is CT scanning?ĬT scanning combines special x-ray equipment with sophisticated computers to produce multiple images of the inside of the body.

Pulmonary Arteries (for pulmonary embolism) 71275.The CT Technologist will contact your referring physician at the time of the examination to review follow-up instructions. You may need a blood test (creatinine level) to check renal functions prior to restarting the medication. Patients on metformin and other oral diabetic medication must not be taken for 48 hours after the CT. Pulmonary Arteries (for pulmonary embolism)ĬTA Carotid Arteries, done at Guilford Radiology, 2010ģD CTA Renal Artery Aneurysm, done at Guilford Radiology, 2010 Patient Preparationĭo not eat solid foods for 4 hours prior to the intravenous contrast injection.Ī creatinine (within 6 months) is required if the patient is over 50 years of age or older. Many different areas can be evaluated with CTA: Intravenous contrast is always used for CT exams. CTA - Angiography Cat Scan Quick Reference Guide for Patients
