About 50329: Backbench renal graft ureter reconstruction
Reports reconstruction of a donor kidney graft’s ureter on the backbench before transplantation when the ureter requires operative repair.
A transplant surgeon performs this work on the donor kidney outside the recipient’s body, before the graft is implanted. The service addresses reconstruction of the graft’s ureter; it is distinct from preparing the kidney’s surrounding tissues or reconstructing its artery or vein. It is generally part of the operative work surrounding a kidney transplant, rather than a procedure performed on the recipient’s native ureter.
Report 50329 when the operative record supports actual reconstruction of the donor graft’s ureter, not merely routine graft preparation. Documentation should identify the ureteral work performed and distinguish it from any preparation or reconstruction of other graft structures. When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and applies a 50% reduction to the others.

50329 billing questions
How does 50329 differ from standard backbench graft preparation?
50329 identifies reconstruction of the donor graft’s ureter. Codes 50323 and 50325 describe standard backbench preparation for cadaveric and donor renal grafts, respectively; the record should support the distinct work reported.
Is this the code for reconstruction of a graft artery or vein?
No. 50329 is for ureteral reconstruction; 50327 addresses renal artery reconstruction and 50328 renal vein reconstruction.
What documentation supports reporting 50329?
The operative report should describe the ureteral reconstruction performed on the donor kidney graft before implantation. A note documenting only routine graft preparation does not establish ureteral reconstruction.
How does the multiple-procedure payment rule affect 50329?
When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and reduces the other procedures by 50%.
Can 50329 be reported with a kidney transplant procedure?
Ureteral reconstruction is backbench work associated with preparing a graft for transplantation, while 50360 and 50365 describe recipient kidney transplant procedures. The operative documentation should support each reported service.
