CPT® Code 47135

Liver allotransplantation, as described by CPT® Code 47135, refers to the surgical procedure in which a liver is transplanted from a donor—either a cadaver or a living individual—into a recipient. This procedure can involve the transplantation of either a partial or whole liver and is performed in an orthotopic manner, meaning the donor liver is placed in the same anatomical position as the original liver. The surgery typically begins with a bilateral subcostal incision, which may be extended with an upper midline incision to provide adequate access to the liver. During the operation, various anatomical structures are carefully dissected and ligated, including the hepatic artery and bile duct, to facilitate the removal of the diseased liver. The procedure also involves the use of venovenous bypass to manage blood flow during the transplantation process. Once the diseased liver is excised, the donor liver graft is positioned and connected to the recipient's blood vessels and bile duct, ensuring proper anastomosis for functionality. This complex surgical intervention is critical for patients with end-stage liver disease or acute liver failure, providing them with a chance for improved health and quality of life.
