CTA Abdominal Aorta with Bilateral Iliofemoral Run-off
CTA Abdominal Aorta with Bilateral Iliofemoral Run-off Clinical History Right calf claudication. Sonography demonstrates segmental occlusion of the distal right superficial femoral and proximal popliteal arteries. Procedure 75635 Precontrast imaging of the abdomen and pelvis was performed followed by arterial phase imaging of the abdomen, pelvis, and lower extremities during injection of 100 cc Isovue 370. Subsequent 2D and 3D image reconstruction was carried out and interpreted. Findings Abdominal aorta: There is mild, diffuse atherosclerotic irregularity of the abdominal aorta without focal aortic stenosis or aneurysm. The renal arteries are solitary bilaterally with very mild (approximately 30%) stenosis of...

Article Overview
This premium article explains a vascular CTA case involving the abdomen, pelvis, renal arteries, iliac vessels, and bilateral lower-extremity runoff, then discusses how the study fits within CPT reporting for CTA imaging. It is aimed at coders, billing staff, and radiology professionals who need to understand the scope of the exam, the code family involved, and the related guidance on reconstruction and contrast-related reporting.
Why This Topic Matters
Accurate reporting of complex CTA runoff studies depends on understanding the anatomic extent of the exam and the CPT framework for bundled CTA services. The article helps readers identify the general coding context, related body regions, and the type of documentation discussed in radiology coding guidance.
