Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 77425 covers

77425 identifies electron-beam radiation delivered intraoperatively to a surgical treatment area. The radiation oncology team coordinates delivery with the surgeon while the operative site is accessible, commonly after tumor removal. The treatment occurs during the surgical episode, rather than as routine external-beam treatments at separate visits. The code represents radiation delivery, not the cancer operation itself. It is used in cancer treatment when radiation is directed to the operative site.

Medicare assigns status X: the service is excluded from physician fee schedule payment because it is not a physician service under the Medicare statute. When covered, it is paid under another fee schedule or payment system. Report it for the intraoperative electron delivery, distinct from the operative procedure.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
