What 50320 covers
This code represents open surgical removal of a kidney from a living donor for transplantation, with cold preservation included. A transplant surgeon or urologist typically performs the operation in a hospital operating room. It applies to procurement from a living donor, rather than removal from a deceased donor or laparoscopic procurement.
Report it for the donor’s operation, not the recipient’s transplant procedure. The operative report should identify the living-donor procurement, the kidney removed, and the approach. Separately performed backbench preparation or reconstruction may be reported with the applicable code when documented. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
