I am writing asking for help/guidance... Can anyone tell me where I can find documentation on specific information on 3D ultrasounds, code 76375. My question is can you bill a 3D ultrasound with just the -TC modifier. We have a radiologist that doesn't want to read the 3D portion but the technician uses the 3D ultrasound for better accuracy in the pictures he/she is getting. Can anyone tell me if this can be done and where I could find information on this? Thank you!!
