Another office is insisting that we bill 49020 or 49040 with a right colectomy (44160). They want us to use a Modifer 59 with the 49020 or 49040. The doctor evacuated a hematoma on the way to do the colectomy. He encounterd the hematoma after the opening. I told them that this is inproper unbundling because they did not do this through another incision, and that I thought it should be part of the procedure. Am I correct?
