CPT® Code 0671T

Insertion of anterior segment aqueous drainage device into the trabecular meshwork, without external reservoir, and without concomitant cataract removal, one or more

The CPT® Code 0671T refers to the procedure involving the insertion of an anterior segment aqueous drainage device into the trabecular meshwork. This procedure is specifically designed for the treatment of chronic or progressive open-angle glaucoma. The term "anterior segment" indicates that the procedure is performed on the front part of the eye, which includes the cornea, iris, and lens. The aqueous drainage device is a specialized implant that helps to facilitate the drainage of aqueous humor, the fluid within the eye, thereby reducing intraocular pressure. This is crucial in managing glaucoma, a condition that can lead to vision loss if not properly treated. The procedure is performed without the use of an external reservoir, meaning that the drainage device operates internally within the eye. Importantly, this procedure is conducted without concomitant cataract removal, indicating that it can be performed independently of any cataract surgery. The technique involves making a small, self-sealing incision in the cornea, which minimizes trauma and promotes quicker recovery. A gonioscope, a type of magnification lens, is utilized to accurately position the drainage device at the angle of the anterior chamber, ensuring optimal placement for effective drainage. The self-sealing nature of the incision means that sutures are not required, further enhancing the procedure's efficiency and patient comfort.
