CPT® Code 47711

Bile duct tumors are uncommon neoplasms that can be classified as either benign or malignant, with the latter being more prevalent. The term "extrahepatic" refers to tumors that develop outside the liver, distinguishing them from "intrahepatic" tumors, which occur within the liver's bile duct system. The excision of an extrahepatic bile duct tumor, as described by CPT® Code 47711, involves surgical removal of the tumor along with the surrounding bile duct tissue. This procedure is critical for managing tumors that may obstruct bile flow or pose a risk of malignancy. The surgical approach typically requires an abdominal incision to access the gallbladder and liver, allowing for direct visualization and identification of the tumor. Once located, the bile duct is transected both above and below the tumor, facilitating its complete excision. Following the removal, the bile duct may be repaired through direct suturing or by employing a Roux-en-Y hepaticojejunostomy, which is a reconstructive technique that connects the bile duct to the jejunum, ensuring continued bile drainage. This procedure is essential for patients diagnosed with extrahepatic bile duct tumors, as it addresses both the tumor and the functional integrity of the biliary system.
