If a physician is using the DaVinci robotic device in the hospital setting would we put a modifier 26 on S2900 for the physician service? I know that S2900 is not regonized by Medicare but wondering if certain commercial carriers may pay for this and I don't think a modifer 26 is required because this HCPCS code is a temporary code. How would we come up with a fee to charge? Just need to verify my opinion. Thanks for any input!
