CPT® Code 67015

The procedure described by CPT® Code 67015 involves the aspiration or release of vitreous, subretinal, or choroidal fluid using a pars plana approach, specifically through a technique known as posterior sclerotomy. In the normal functioning of the eye, ocular fluid circulates between the vitreous body and the choroid, facilitated by a membrane called the retinal pigment epithelium (RPE). This membrane plays a crucial role in maintaining the balance of fluid by actively pumping ions and water from the vitreous into the choroid, preventing fluid accumulation. However, when there is an imbalance—either due to increased fluid inflow or decreased outflow—fluid can accumulate in the subretinal space. This accumulation can lead to elevated intraocular pressure, which poses a significant risk for complications such as retinal detachment. To address this issue, the procedure involves the careful aspiration of the excess fluid to alleviate the pressure within the eye. The process begins with the application of anesthetic drops to ensure patient comfort, followed by the use of an antibacterial solution to cleanse the eye's surface. A specific area in the pars plana is then identified and marked for the procedure. A small-gauge needle, connected to an empty syringe, is inserted through this marked area into the posterior segment of the eye to aspirate the accumulated fluid. After the aspiration, the needle is withdrawn, and a cotton-tipped applicator is used to apply pressure at the puncture site to prevent any potential leakage of fluid. Finally, the puncture site is assessed for any signs of fluid leakage, and antibiotic eye drops may be administered to reduce the risk of infection.
