Ask Dr. Z

I know you answered a similar question in 2012, but I'm wondering if the recommendation is still the same. We performed an EVAR in which the SMA was also stented. A few weeks later the patient returned to us for evaluation of a possible endoleak and evaluation of what appeared to be a stent fragment in her left external iliac artery. A diagnostic study was performed, and it was determined that her SMA stent had fractured and migrated to her left external iliac artery. The stent was balloon dilated in place in the external iliac. The stent was not otherwise manipulated, and no other interventions were performed. How would you bill for the balloon dilation of the stent?
