CPT code 50810: Ureter-bowel connection, ureteral fusion2026 Medicare rate & RVUs

Medicare pays $1,329.69 for 50810 nationally in a facility.

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

What 50810 covers

A urologist performs this operation to connect a ureter with bowel so urine can drain into the intestinal tract. It may be part of urinary reconstruction or diversion, typically in a hospital operating room. The operative report should identify the ureter and bowel involved and describe the connection actually created; the code is not a general label for every urinary diversion or bowel reconstruction.

Select the code from the documented procedure, distinguishing this ureter-bowel fusion from direct ureter implantation, replacement of a ureter with bowel, or construction of a bowel bladder. CMS assigns a 90-day major-surgery global period, including 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 50% multiple-procedure reduction. CMS treats this as a single coded operation rather than a modifier-50 bilateral service. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.
