CPT® Code 47612

The procedure described by CPT® Code 47612 involves a cholecystectomy, which is the surgical removal of the gallbladder, performed using an open surgical technique. This procedure is accompanied by an exploration of the common bile duct and the creation of a choledochoenterostomy, which is a surgical connection between the common bile duct and the intestine. The operation begins with an incision in the upper abdomen, typically located in the right subcostal region, allowing access to the gallbladder and surrounding structures. During the procedure, various anatomical landmarks such as the hepatoduodenal ligament, gallbladder, and triangle of Calot are visualized to facilitate safe dissection. The surgeon carefully dissects the tissue down to the cystic duct's junction with the common duct and continues to the cystic artery. After freeing the gallbladder from the hepatic bed and ligating the cystic duct, the common bile duct is explored to identify and remove any gallstones. This is achieved by inserting a biliary balloon catheter into the common duct, which is then manipulated to extract stones from both the common bile duct and the hepatic ducts. Following the exploration, a choledochoenterostomy is performed, which can be configured as either a side-to-side or end-to-side anastomosis, with the end-to-side configuration being the preferred method. This involves mobilizing the common bile duct and connecting it to the duodenum, ensuring proper drainage of bile into the digestive tract. The procedure concludes with the removal of the gallbladder and closure of the incision around any necessary drains.
