CPT® Code 47564

The procedure described by CPT® Code 47564 involves a laparoscopic cholecystectomy, which is a minimally invasive surgical technique used to remove the gallbladder. This procedure is performed through small incisions in the abdomen, allowing for reduced recovery time and less postoperative pain compared to traditional open surgery. During the operation, the surgeon not only removes the gallbladder but also explores the common bile duct to ensure that no stones are present, which could lead to complications. The process begins with the creation of a small incision at the navel, through which a trocar is inserted to allow access for a laparoscope—a thin tube equipped with a camera that provides visualization of the internal structures. The abdomen is inflated with carbon dioxide to create a working space for the surgeon. Additional incisions are made to insert other surgical instruments necessary for the procedure. The gallbladder is carefully identified and, if necessary, drained of bile to facilitate its removal. Key anatomical structures, such as the cystic artery and cystic duct, are meticulously dissected and ligated to prevent bleeding. The exploration of the common bile duct is critical, as it allows for the identification and removal of any gallstones that may have migrated into the duct. After ensuring the area is clear of stones, the gallbladder is detached from the liver and removed through one of the small incisions. This comprehensive approach not only addresses the gallbladder issue but also safeguards against potential complications related to the biliary system.
