CPT® Code 66625

The procedure described by CPT® Code 66625 is known as an iridectomy, specifically a peripheral iridectomy performed as a separate procedure to treat glaucoma. In this context, an iridectomy involves the surgical removal of a portion of the iris, which is the colored part of the eye. 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. This drainage is crucial for reducing intraocular pressure (IOP), which is often elevated in patients suffering from glaucoma. Elevated IOP can lead to damage of the optic nerve and potential vision loss if not managed effectively. This procedure is particularly indicated for patients with angle-closure glaucoma, a condition where the drainage angle of the eye becomes blocked, leading to a rapid increase in IOP. When less invasive treatments, such as laser iridotomy, fail to achieve the desired reduction in IOP, a peripheral iridectomy may be necessary. During the procedure, a topical anesthetic is applied to ensure patient comfort. An incision is made in the cornea, typically at the limbus, which is the junction where the cornea meets the sclera. A small, full-thickness section of the iris is then excised. Unlike some surgical procedures, the corneal incision made during this process is generally not sutured, as it is expected to heal naturally. 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.
