Insertion of anterior segment aqueous drainage device, without extraocular reservoir, internal approach, into the trabecular meshwork; initial insertion

The procedure described by CPT® Code 0191T involves the insertion of an anterior segment aqueous drainage device, which is specifically designed to manage conditions such as chronic or progressive open-angle glaucoma. This type of device is characterized by the absence of an extraocular reservoir, meaning that it operates entirely within the eye. The insertion is performed through an internal approach, targeting the trabecular meshwork, which is a crucial component of the eye's drainage system. The procedure begins with the creation of a small, self-sealing incision in the cornea, which is then deepened to gain access to the anterior chamber of the eye. To ensure precise placement of the drainage device, a magnification lens, such as a gonioscope, is utilized. This allows the surgeon to accurately position the drainage device at the angle of the anterior chamber, ensuring that the terminal end of the device is correctly situated within the trabecular meshwork. Notably, due to the minimal size of the incision, there is no need for suturing, as the incision will naturally seal itself. For any additional aqueous drainage devices that may be inserted during the same surgical session, the appropriate code to report is 0376T.
