CPT® Code 66630

The procedure described by CPT® Code 66630 refers to an iridectomy, specifically a sector iridectomy performed with a corneoscleral or corneal section, which is classified as a separate procedure. This surgical intervention involves the removal of a portion of the iris, which is the colored part of the eye, to effectively treat glaucoma. The primary goal of this procedure is to facilitate the drainage of aqueous humor, the fluid within the eye, from the anterior chamber to the posterior chamber. By doing so, it helps to lower intraocular pressure (IOP), which is crucial in managing glaucoma, particularly in cases of angle-closure glaucoma where other treatments, such as laser iridotomy, have not succeeded in achieving adequate pressure reduction. During the procedure, a topical anesthetic is applied to ensure patient comfort. The surgeon makes an incision in the cornea, typically at the limbus, the junction where the cornea meets the sclera. In this specific procedure, a larger, wedge-shaped section of the iris is excised compared to other related procedures, such as CPT® Code 66625, which involves a smaller full-thickness section. Importantly, the corneal incision made during the procedure is generally left open, as it is expected to close and heal naturally without the need for sutures. Post-operative care may include the application of antibiotic eye drops, and the use of a contact lens bandage or an eye patch to protect the eye during the healing process.
