Ask Dr. Z

Our hospital is using a new device called the Reflow Temporary Spur stent. After performing an angioplasty, they insert the Temporary Spur Stent and inflate it which causes the drug-coated spurs to create channels in the vessel lining and the physician leaves it in place for a period of time to allow the drug to be deposited into the vessel lining to prevent recoiling after angioplasty.

Please note we code for pro-fee and facility. Would this procedure be coded as an angioplasty procedure with use of the reflow system included? Would this be an unlisted code? For pro-fee, if we can code the angioplasty code, would we also assign a -22 modifier for the extra work?
