Code for TEVAR or EVAR be used for repair of endoleak with previous EVAR?

Date: Dec 15, 2020

Question:

Placement of Chimney for previous EVAR with endoleak by vascular surgeon. Per note: "Open left subclavian access, percutaneous right brachial access, percutaneous bilateral femoral access with only right side using larger than 12 French sheath. Selective cath and stent placements in right renal, SMA, and celiac arteries. Decision to continue with the extension of the infra-abdominal endograft and ends stenting of the aforementioned arteries. A 6 mm x 79 mm was placed in the right renal artery. A 6 mm x 59 mm stent was placed in the SMA. The right groin sheath was removed and the artery was dilated serially to 18 French size. A Medtronic Navion endograft was then placed over the Lunderquist wire and deployed into the abdominal aorta just below the celiac artery takeoff. The balloon-expandable stents in the right renal artery and SMA were then deployed. Abdominal aortogram showed inadequate overlap of prior endograft. Another Medtronic endograft was deployed." Provider wants to use code 33881. It seems this is in abdominal aorta and not thoracic; however, Navion device is used for TAAA. What are your thoughts?
