The code captures a distinct intraoperative surgical service enabling targeted, single-fraction radiation delivered directly to the lumpectomy cavity immediately after tumor excision. Nationally, this code is relevant for surgical oncologists, radiation oncologists, and hospitals offering breast-conserving surgery with IORT capabilities.
