What 50323 covers
This service covers preparation of a deceased donor kidney outside the recipient’s body before transplantation. The transplant surgeon prepares the graft for implantation, including work needed to assess and ready its vessels and ureter. It is performed in connection with kidney transplantation, typically in a hospital operating room or transplant setting. This back-table work follows donor-organ recovery and precedes implantation in the recipient.
CPT 50323 has Medicare physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. Report it for the cadaver-donor graft preparation service, not for the recipient’s transplant operation itself. Separate codes describe reconstruction of the graft’s renal vein, artery, or ureter when that work is performed.
