Ask Dr. Z

Are codes 33880, 37236-XU, and 37217 correct for the following, or are stents bundled in 33880?

"ON back table primary thoracic endovascular aortic device was deployed 2 fenestrations were placed according to preop plan for lt common carotid/subclavian artery,fenestrations reinforced, device reconstrained within inner sleeve and resheathed within original device.Next arteriotomy was serially dilated and primary fenestrated thoracic endovascular device, Terumo aortic relay Pro 34/30 X 209mm device advanced under fluoroscopic guidance into arotic arch where it was deployed under fluoroscopic and 3D fusion guidance. Next from the lt femoral access a 7 FR Oscor twist conformable sheath was advanced into the thoracic aortic device multiple attempts were made to select Lt carotid fenestration. Due to double curve of type III aortic arch this was unsuccessful. Attention was turned to performing retrograde cannulation/stenting of lt carotid/subclavian fenestrations. From retrograde 7 FR sheath LT common carotid/subclavian primarily stented in retrograde fashion."
