Ask Dr. Z

The interventional radiologist orginally punctured the right common femoral and then catheterized and imaged the left hypogastric. He then selectively catheterized and imaged the left superior gluteal, left inferior gluteal, and the left iliofemoral arteries. I have the following codes so far: 36247, 36248 x 2, 75736, and 75774 x 3. He then catheterized the left circumflex iliac artery and the left inferior epigastric artery and did diagnostic imaging in both. I am not sure how to code these two in addition to the codes above. All of the imaging was done to check for bleeding. Patient is post trauma with internal hemorrhage.
