CPT® Code 47801

The procedure described by CPT® Code 47801 involves the placement of a choledochal stent, which is a medical intervention aimed at alleviating chronic obstruction of the common bile duct. This obstruction is often associated with malignancies, which can lead to significant complications if not addressed. During the procedure, a midline abdominal incision is made to provide access to the liver, gallbladder, and common bile duct. Once these structures are exposed, the common bile duct is incised to allow for the insertion of a biliary plastic or metal tube, known as a stent, into the narrowed segment of the duct. This stent serves to maintain patency and facilitate the flow of bile, thereby relieving the obstruction. After the stent is placed, the incision in the common bile duct is closed, and the effectiveness of the procedure is verified through a cholangiogram, which is a separate reportable imaging study that assesses the bile duct's patency. Following the completion of the stent placement, the surgical wound is irrigated, and drains may be placed as necessary to manage any potential fluid accumulation. Finally, the abdominal incision is closed in layers to promote proper healing and minimize the risk of complications.
