CPT® Code 47142

The procedure described by CPT® Code 47142 refers to a donor hepatectomy performed on a living donor, specifically a total right lobectomy that includes the removal of liver segments V, VI, VII, and VIII. This surgical intervention is essential for organ transplantation, where a portion of the liver is harvested from a healthy individual to be transplanted into a recipient with liver failure or other liver-related conditions. The term 'hepatectomy' denotes the surgical excision of liver tissue, and in this case, it involves the complete removal of the right lobe of the liver. The procedure is conducted under general anesthesia and requires careful planning and execution to ensure the safety of the donor while maximizing the viability of the liver segments for transplantation. Cold preservation of the excised liver segments is a critical step, as it helps maintain the organ's function until it can be transplanted into the recipient. The surgical approach typically involves a midline incision, allowing the surgeon to access the liver effectively. This procedure is performed by a specialized surgical team trained in liver transplantation, ensuring that both the donor's and recipient's needs are met with the utmost care and precision.
