CPT® Code 66852

The procedure described by CPT® Code 66852 involves the removal of lens material from the eye using a pars plana approach, which is a surgical technique that accesses the posterior segment of the eye. This approach is characterized by an incision made in the pars plana, a region of the eye located between the iris and the vitreous body. The surgery may be performed with or without vitrectomy, a procedure that involves the removal of the vitreous gel that fills the eye. During the operation, the surgeon utilizes an operating microscope to visualize the internal structures of the eye clearly. The process begins with the creation of an incision in the conjunctiva and Tenon’s layer to expose the sclera, the white outer layer of the eyeball. To ensure a bloodless field, hemostasis is achieved through cautery. The sclera is then marked at the inferotemporal quadrant, and sutures are placed on either side of this mark to facilitate a precise incision. A microvitreoretinal (MVR) blade is used to make a careful incision in the sclera, allowing access to the posterior segment. An infusion line is inserted to maintain intraocular pressure and is secured with the sutures. The procedure may require additional sclerotomies to properly position the infusion line. Once the necessary access is established, the lens material is removed through irrigation and aspiration techniques, and if vitrectomy is indicated, vitreous fluid is also extracted. Throughout the procedure, the intraocular pressure is closely monitored to ensure the eye remains formed. At the conclusion, fluid may be injected to restore normal intraocular pressure, and the surgical site is meticulously closed to prevent any leakage, ensuring a successful outcome for the patient.
