I have a situation where we do X-Rays in the office, we do not have an Xray machine, just a C-Arm so the orthopedic office across the hall lets us borrow their X-ray machine one day per week. They do not bill for the TC on these, however, they own the machine, but we employ the tech that takes the x-rays and our doctor does the interperatation and report. Since they are not billing at all and we employ the tech, could I bill for global, or should I do 26 just to be safe?
