What 50370 covers
This service is removal of a kidney previously placed by renal transplantation. A transplant or urologic surgeon typically performs the operation in a hospital or other surgical facility. Situations may include a failed graft, persistent infection involving the graft, graft intolerance, or a graft-related malignancy. The operative work concerns the transplanted kidney, not simply removal of a recipient’s native kidney or preparation of a donor kidney.
Report the code when the operative documentation supports removal of the renal allograft and identifies the clinical reason and the structure removed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

50370 billing questions
How is this different from recipient nephrectomy?
This code is for removal of a transplanted kidney. Recipient nephrectomy, code 50340, concerns removal of a recipient kidney rather than removal of the renal allograft.
Can this be reported with a new kidney transplant?
It may be reported with a transplant procedure when the failed allograft is removed and a new kidney is implanted during the same operative episode. Document the separate removal and implantation work.
Does the 90-day global period include related postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Should modifier 50 be used for removal of two grafts?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What should the operative report establish?
It should identify the transplanted kidney that was removed, describe the removal performed, and document the clinical indication, such as graft failure or graft-related infection.
