I have an ASC billing 64415-59 & 76942-TC and a anesthesiologist also billing 64415 & 76942 for the same patient/same surgery. The way I understand it, 64415 may not be billed as a separate procedure, modifier 59 or not. That it is considered bundled into the arthroscopic shoulder surgery (29807,23130, 23410, 29823, 23700). Am I correct or not?
