Esophageal Sphincter Augmentation

Two new CPT codes were established in 2017 to represent an esophageal sphincter augmentation procedure that is performed for GERD, using a device made up of a band of titanium beads with magnetic cores.

43284 Laparoscopy, surgical, esophageal sphincter augmentation procedure, placement of sphincter augmentation device (ie, magnetic band), including cruroplasty when performed.

43285  Removal of esophageal sphincter augmentation device.

This band is placed laparoscopically around the lower esophageal sphincter to augment this muscle and reduce instances of reflux.  The magnetic core within the beads keeps them attached to one another but as food passes through the esophagus the magnetic field is broken and the beads separate to allow food to pass into the stomach.  Once the food has passed the magnetic field pulls the beads back together closing off the lower esophagus.

Note that CPT code 43284 states “laparoscopic” placement of this device but CPT code 43285 just states “removal” of device which can be performed either laparoscopically or open.
