CPT® Code 47715

The procedure described by CPT® Code 47715 involves the excision of a choledochal cyst, which is a congenital anomaly of the bile duct characterized by an abnormal cystic dilation of the biliary duct(s). This condition can lead to various complications, including biliary obstruction, cholangitis, and pancreatitis, necessitating surgical intervention. During the procedure, the surgeon makes a midline abdominal incision to gain access to the abdominal cavity, allowing for the exposure of the gallbladder and liver. Once the surgical field is prepared, the choledochal cyst is identified. The next step involves transecting the bile duct both above and below the cyst to remove the dilated portion effectively. After excising the cyst, the surgeon has the option to repair the bile duct by suturing the remaining segments together. Alternatively, if the situation requires, a Roux-en-Y hepaticojejunostomy or another reconstruction technique may be employed to ensure proper bile flow and prevent future complications. This procedure is critical for addressing the underlying issues associated with choledochal cysts and restoring normal biliary function.
