What 76945 covers
This service uses ultrasound imaging to guide the instrument during chorionic villus sampling, which obtains placental tissue for prenatal diagnostic testing. It describes the guidance service, not collection of the specimen. Obstetricians, maternal-fetal medicine physicians, and radiologists may provide or report the guidance in connection with CVS.
Medicare assigns 76945 physician fee schedule status C (carrier priced): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service has a professional interpretation component, reportable with modifier 26, and a technical component for equipment and staff, reportable with modifier TC. Report the global service without either modifier when both components are billed together. The separate CVS procedure is represented by 59015; 76945 identifies ultrasound guidance.
