CPT® Code 47147

The procedure described by CPT® Code 47147 involves the backbench reconstruction of a liver graft, which can be sourced from either a cadaver or a living donor, prior to its transplantation into a recipient. This intricate process is essential for ensuring that the liver graft is adequately prepared to function effectively once transplanted. During this procedure, any anatomical variations in the arterial or venous blood supply to the donor liver are meticulously identified and reconstructed. This is performed in a controlled environment, often referred to as a back table procedure, where the graft is examined in detail. The hepatic venous drainage system is inspected thoroughly, and any anomalies in the blood vessels are corrected through reconstruction and anastomosis, which involves surgically connecting blood vessels to restore proper blood flow. The common hepatic artery, which is one of the three branches of the celiac artery, is typically responsible for supplying blood to the liver. However, it is important to note that the liver may also receive blood supply from the other two branches of the celiac artery, namely the splenic and gastric arteries, or even from the superior mesenteric artery. These alternative arterial sources are preserved during the procedure and are revascularized by connecting them to the main hepatic circulation, ensuring that the liver graft receives adequate blood supply post-transplantation. This procedure is critical for the success of the liver transplant, as it directly impacts the viability and functionality of the graft once it is implanted into the recipient.
