CPT® Code 0376T

Deleted

Insertion of anterior segment aqueous drainage device, without extraocular reservoir, internal approach, into the trabecular meshwork; each additional device insertion (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 0376T involves the insertion of an anterior segment aqueous drainage device, specifically designed for the treatment of chronic or progressive open-angle glaucoma. This procedure is performed without the use of an extraocular reservoir and utilizes an internal approach to effectively manage intraocular pressure. During the procedure, a small, self-sealing incision is made in the cornea, which is then deepened to access the anterior chamber of the eye. A specialized magnification lens, such as a gonioscope, is employed to accurately place and position the drainage device, also referred to as a shunt, at the angle of the anterior chamber. The terminal end of the drainage device is strategically positioned within the trabecular meshwork, facilitating the drainage of aqueous humor to alleviate pressure within the eye. Notably, the small corneal incision does not require closure, as its size allows for self-sealing, promoting a swift recovery. It is important to note that the initial insertion of an aqueous drainage device is reported using CPT® Code 0191T, while CPT® Code 0376T is designated for each additional device inserted during the same surgical session.
