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

What 50770 covers

In a transureteroureterostomy, the surgeon connects the affected ureter to the opposite ureter so urine can drain through the other side into the bladder. Urologists typically perform this reconstructive operation in a surgical facility when the usual route from a kidney to the bladder cannot be restored or used. The operative report should identify the ureteral anatomy, the side and course of the connection, and the reason for redirecting drainage.

Report this code for the cross-connection between ureters, not for reconnecting separated ends of the same ureter or implanting a ureter into the bladder. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this procedure. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
