What 76984 covers
Code 76984 identifies diagnostic ultrasound of the thoracic aorta performed during an operation. It describes an examination of the aorta for diagnostic purposes, rather than ultrasound used only to guide another intraoperative procedure. Physicians report the professional portion for interpretation and the technical portion for equipment and staff, as applicable in the operative setting.
For Medicare, 76984 has physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service. Reporting 76984 without either modifier represents the global service. The code is distinct from 76998, which describes ultrasound guidance during an intraoperative procedure.
