CPT® Code 47740

A Roux-en-Y cholecystoenterostomy, designated by CPT® Code 47740, is a surgical procedure primarily aimed at addressing biliary obstruction. This operation is a type of biliary bypass that facilitates the drainage of bile from the gallbladder directly into the small intestine, specifically the jejunum. The procedure is characterized by the construction of a Roux-en-Y limb, which is a surgical technique that creates a Y-shaped connection between the gallbladder and the small intestine. During the operation, an abdominal incision is made along the midline to access the gallbladder and a segment of the small intestine. The gallbladder is carefully dissected to prepare it for the anastomosis, which is the surgical connection between two structures. The jejunum, a part of the small intestine, is mobilized and divided to form the Roux-en-Y limb. The distal end of the divided jejunum is then anastomosed to the gallbladder, allowing bile to flow directly into the small intestine, while the proximal end is connected to the side of the jejunum. This procedure is particularly beneficial for patients who have experienced biliary obstruction, as it restores the normal flow of bile, which is essential for digestion and absorption of fats. It is important to note that this specific code does not include a gastroenterostomy, which is a different procedure that may be performed in conjunction with a Roux-en-Y cholecystoenterostomy under a different code (CPT® Code 47741).
