CPT® Code 43284

Laparoscopy, surgical, esophageal sphincter augmentation procedure, placement of sphincter augmentation device (ie, magnetic band), including cruroplasty when performed

The procedure described by CPT® Code 43284 involves a laparoscopic surgical technique aimed at augmenting the esophageal sphincter. This is specifically achieved through the placement of a sphincter augmentation device, commonly referred to as a magnetic band, around the lower esophageal sphincter (LES). The primary purpose of this procedure is to treat gastroesophageal reflux disease (GERD), a condition where stomach contents flow back into the esophagus, causing symptoms such as heartburn and regurgitation. During the laparoscopic approach, the gastroesophageal junction (GEJ) is visualized, allowing the surgeon to perform the necessary dissection with minimal invasiveness. The procedure may also include cruroplasty, which is a surgical repair of the diaphragm's crura, particularly when there is a hiatal hernia present. This involves adjusting the opening in the diaphragm to prevent the stomach from protruding into the chest cavity. The magnetic band itself is designed to maintain closure of the LES while allowing it to open during swallowing, thus providing a functional solution to the reflux issue. Overall, this procedure combines advanced laparoscopic techniques with innovative device technology to enhance patient outcomes in managing GERD.
