Ask Dr. Z

"An 8 x 39 mm VBX stent was advanced into the terminal aorta and deployed just above the bifurcation. This was post-dilated to 10 mm with a 10 x 40 mm Charger balloon. Next, bilateral kissing iliac stents were advanced through the sheath, 6 x 29 mm stents bilaterally. The stents were positioned just inside of the aortic stent and simultaneously deployed. These were slightly over-dilated. Retrograde injection through the sheath demonstrates wide patency of the aortic stent and bilateral common iliac stents." I coded 37221-50 for this case; is this correct? I did not report code 37236 for the aorta stent placement based on previous advice. Just want to make sure this is still your recommendation.
