Ask Dr. Z

How would you code for the ascending aorta stent grafts in the following scenario? "The physician joined me during this portion of the case. He selectively cannulated the left ventricle using a combination of angled Glidewire and angled glide catheter, and a wire exchange for the Lunderquist wire was performed into the left ventricle. This was left in to mark the ostium of the left coronary artery. Injection of contrast allowed us to perform left coronary angiogram. Wire was left in the anterior descending coronary artery, and catheter was left in the ostium. I proceeded with stent graft repair of ascending thoracic aorta. Cook 38 x 77 stent was introduced and advanced and deployed 5 mm distal to the left coronary artery, then ballooned and pulled distally so the distal portion of the graft abutting the ostium of the innominate artery. Next a Cook 42 x 81 stent graft was then placed and deployed 5 mm distal to the left coronary artery. Two stent grafts were then placed T11 to T4. Additional stent graft was placed just distal to the subclavian artery down to the previously placed stent."
