CPT® Code 44720

The procedure described by CPT® Code 44720 involves the backbench reconstruction of an intestinal allograft, which can be derived from either a cadaver or a living donor, prior to its transplantation into a recipient. This process is critical in preparing the allograft for successful integration into the recipient's body. The primary focus of this procedure is the venous anastomosis, which is the surgical connection of the superior mesenteric vein of the allograft to an extension venous graft. The allograft is carefully preserved, typically received on ice and immersed in a cold preservation solution to maintain its viability until the surgical procedure is performed. The meticulous nature of this reconstruction ensures that the allograft is adequately prepared to facilitate proper blood flow and function once transplanted. It is important to note that if additional venous extension grafts are necessary during the procedure, each of these is reported separately, emphasizing the complexity and individualized nature of the surgical intervention.
