Question: New York Subscriber Answer: Here's why: Professional component You report 37205 (Transcatheter placement of an intravascular stent[s], [except coronary, carotid, and vertebral vessel], percutaneous; initial vessel) for stent placement in a single vessel. If the radiologist places a stent in a separate, additional vessel at the same encounter, then you also report +37206 (... each additional vessel [List separately in addition to code for primary procedure]). Therefore 37205 (one vessel) and +37206 (one additional vessel) represent two vessels. You should report 75960-26 twice because you may report it for each vessel in which the radiologist placed a stent. Check your payer's preference for reporting 75960 more than once. Some may prefer a single line with two units while others may prefer separate line items with a modifier attached to the second.
