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

What 77424 covers

77424 reports intraoperative radiation treatment delivered with x-rays to a target while surgery is underway. The radiation oncology team coordinates delivery with the operating surgeon so treatment can be directed to the operative site. The code identifies the radiation delivery service, rather than the broader radiation course or the physician’s management of intraoperative treatment. It distinguishes x-ray delivery from the intraoperative electron delivery represented by 77425.

Medicare classifies 77424 as status X, a statutory exclusion because it is not a physician service under the Medicare statute; the physician fee schedule does not pay it. When covered, Medicare pays it under another fee schedule or payment system. Radiation oncologists report it for the intraoperative delivery, while 77469 identifies intraoperative radiation treatment management.
