CPT® Code 43285

The procedure described by CPT® Code 43285 involves the removal of an esophageal sphincter augmentation device, which is a laparoscopic surgical intervention aimed at treating gastroesophageal reflux disease (GERD). This device, often referred to as a magnetic band, is implanted around the lower esophageal sphincter (LES) to enhance its function. The laparoscopic approach allows for minimal invasiveness, which is beneficial for patient recovery. During the procedure, the gastroesophageal junction (GEJ) is carefully visualized, and the area surrounding the device is meticulously dissected to avoid damage to surrounding structures. The procedure includes the identification and preservation of critical anatomical components such as the mediastinal cavity and the phrenoesophageal ligament, which are essential for maintaining the integrity of the esophagus and diaphragm. The posterior vagus nerve is also located and protected during the operation. The device itself consists of a series of interlinked titanium beads with magnetic cores that work together to keep the LES closed, while allowing it to open during swallowing. The removal process involves careful dissection to free the device from the esophagus, ensuring that the surrounding tissues are not harmed. After the device is successfully extracted, the surgical instruments are withdrawn, and the abdominal cavity is closed using sutures, staples, or Steri Strips, completing the procedure.
