CPT® Code 47900

The procedure described by CPT® Code 47900 involves the surgical suture of the extrahepatic biliary duct, specifically addressing a pre-existing injury. This procedure is classified as a separate procedure, indicating that it is performed independently and is not part of a more extensive surgical intervention. The extrahepatic biliary duct is a critical component of the biliary system, responsible for transporting bile from the liver and gallbladder to the duodenum. In cases where this duct has been injured, it is essential to repair it to restore normal bile flow and prevent complications such as bile leaks or infections. The surgical approach typically involves making an abdominal incision along the midline, allowing access to the liver, gallbladder, and the extrahepatic bile ducts. Once the injury is identified, the surgeon evaluates the extent of the damage and proceeds to repair the duct using sutures. Following the repair, the surgical site is irrigated to reduce the risk of infection, and drains may be placed to facilitate the removal of any excess fluid. Finally, the abdominal incision is closed in layers to promote proper healing.
