(Active) Effective Date: N/A Revision Date: N/A Diagnostic Radiology - Computed Tomographic Angiography Radiology Feed
Computed tomographic angiography (CTA) of the abdomen with contrast material, including non-contrast images if performed, and image post-processing.
Modifiers 26 (professional component) and TC (technical component) may be appended as appropriate based on the services performed.Modifiers 51 (multiple procedures) and others may be applied as necessary.
The CTA abdomen is medically necessary to evaluate patients with suspected abdominal vascular pathology, such as aneurysm, stenosis, thrombosis, or trauma, to guide treatment decisions.
The physician supervises the intravenous (IV) line placement, contrast administration, image acquisition, and post-processing image reconstruction performed by a technician. The radiologist interprets the images and creates a report.

In simple words: This is a CT scan of your abdomen's blood vessels. A special dye is injected to help the scan show the blood vessels clearly. The scan creates detailed images of the blood vessels which a doctor will examine to look for problems.
Computed tomographic angiography (CTA) of the abdomen is performed using contrast material injected intravenously.The procedure includes acquisition of both contrast-enhanced and non-contrast images (if obtained),post-processing image reconstruction, and interpretation of the resulting images by a radiologist to assess the abdominal vasculature.A report detailing the findings is generated.
Example 1: A patient presents with abdominal pain and suspected abdominal aortic aneurysm. A CTA abdomen is performed to visualize the abdominal aorta and its branches to assess for aneurysm formation or other vascular abnormalities., A patient with a history of peripheral artery disease undergoes CTA of the abdomen to evaluate for visceral artery involvement and assess the extent of atherosclerosis., A patient is evaluated for unexplained abdominal bleeding. A CTA of the abdomen is performed to identify the source of bleeding by visualizing the blood vessels within the abdomen.
Complete patient history and physical examination, indication for the study, images acquired (both contrast-enhanced and non-contrast if applicable), radiologist's interpretation and report.
** This code encompasses a comprehensive CTA of the abdomen, including contrast and non-contrast images if acquired, image post-processing, and radiologist interpretation.Accurate documentation and adherence to payer policies regarding modifier use are crucial for appropriate reimbursement.
