We bill for the professional side of x-rays. We recently got a denial back on 73560. We billed 73565-26, and 73560-26-50. The hospital billed 73565-TC, and 73560-TC-Lt, 73560-TC-Rt. I cannot see if they got paid or denied for their portion. My question is, does it make a difference that they billed Lt/Rt separately, and we used modifier -50? I don't know why it would, but I don't see anything other reason for this. Any ideas?
