CPT® Code 66184

The CPT® Code 66184 refers to the procedure known as the revision of an aqueous shunt to an extraocular equatorial plate reservoir, specifically performed without the use of a graft. This procedure is typically indicated for patients experiencing complications related to their aqueous shunt, which is a device used to manage intraocular pressure (IOP) in conditions such as glaucoma. The revision may be necessary due to various issues, including the formation of scar tissue at the posterior plate, which can obstruct the proper functioning of the shunt. Other potential complications that may necessitate this revision include corneal damage, the development of small cataracts, infections, and bleeding. During the procedure, an incision is made in the conjunctival tissue over the plate to access the shunt. The surgeon then removes any scar tissue that has formed, which is crucial for restoring the shunt's functionality. After the removal of the scar tissue, the conjunctival incision is sutured closed to promote healing. This procedure is essential for maintaining optimal IOP levels and preventing further ocular complications, thereby improving the patient's overall eye health and quality of life.
