CPT® Code 47800

The procedure described by CPT® Code 47800 involves the surgical reconstruction of the extrahepatic biliary ducts, which are the ducts outside the liver that transport bile from the liver and gallbladder to the duodenum. This procedure is typically indicated when there is a disease or injury affecting these ducts, necessitating surgical intervention to restore normal bile flow. The operation begins with a midline abdominal incision, allowing access to the liver, gallbladder, and the extrahepatic bile ducts. Once the area is exposed, the surgeon identifies the specific segment of the bile duct that is diseased or injured. After evaluating the extent of the injury, the affected segment is excised, and the remaining healthy ends of the bile ducts are sutured together in an end-to-end anastomosis. This technique is crucial for re-establishing continuity within the biliary system. Following the reconstruction, the surgical site is irrigated to prevent infection, and drains may be placed to facilitate fluid removal. Finally, the abdominal incision is closed in layers to promote proper healing.
