Ask Dr. Z

I have a TEVAR procedure coded as 33881, 75957-26, 36200, and 34812-LT. However, they also removed previously placed stents from the iliac and femoral arteries on the left side due to re-stenosis and dissection and placed new stents in the left common iliac, left external iliac, and the CFA. I am going to omit 34812 and 36200 and bill codes 37221, 37223, and 37226. Is this how you would code this procedure? I was a little concerned that the extremity stents had to be removed just to perform the TEVAR and are bundled, but there was a dissection, so would that show medical necessity? No mention of the % of re-stenosis. They also tried to access the right femoral and could not, but left a 5 French sheath there and decided to go through the left brachial artery. I am thinking that is all bundled too but am not sure. I am new to coding these and any help would be appreciated.
