CPT® Code 66505

The CPT® Code 66505 refers to a specific surgical procedure known as iridotomy by stab incision, which is performed as a separate procedure. This technique is particularly utilized in the management of various ocular conditions, including glaucoma, iris atrophy, papillary membrane adhesions, and aniridia. The procedure involves making a stab incision through the conjunctiva and into the lamellar sclera, allowing for the creation of a tunnel that facilitates access to the anterior chamber of the eye. The use of an operating microscope is essential for visualizing the intricate structures of the eye during this procedure. The stab incision technique is characterized by its precision and the careful dissection of a superficial tunnel using a side-to-side approach, which extends to the limbus. This method is crucial for entering the anterior chamber horizontally, thereby enabling the surgeon to effectively address the underlying issues causing increased intraocular pressure. The procedure may also involve transfixion, particularly in cases of iris bombe, where the iris is abnormally positioned against the anterior chamber, obstructing the flow of aqueous humor. By restoring the normal position of the iris and improving fluid dynamics within the eye, this procedure plays a vital role in alleviating symptoms and preventing further complications associated with elevated intraocular pressure.
