Report Renal CTA With 74175

Published on Sun Aug 10, 2008

Question: What is the appropriate CPT code for a renal CTA?Oklahoma SubscriberAnswer: You should report a renal CTA with 74175 (Computed tomographic angiography, abdomen, with contrast material[s], including noncontrast images, if performed, and image postprocessing).Here's why: The renal arteries branch off of the abdominal aorta below where the superior mesenteric branches off and above the gonadal arteries. A renal scan typically covers the area between the supraceliac aorta and the iliac bifurcation. This anatomical placement puts a renal scan in the abdomen (74175).Tip: Physicians may order a renal CTA to look for renal artery stenosis. If the CTA confirms this diagnosis, report 440.1 (Atherosclerosis; of renal artery).
