CPT® Code 67025

Injection of vitreous substitute, pars plana or limbal approach (fluid-gas exchange), with or without aspiration (separate procedure)

The procedure described by CPT® Code 67025 involves the injection of a vitreous substitute into the eye, specifically through a pars plana or limbal approach. The vitreous humor is a gel-like substance that fills the space behind the lens of the eye and is crucial for maintaining the shape of the eyeball and supporting the retina. As individuals age, this gel-like substance can become more fluid, and it may be lost due to various factors such as eye injuries or surgical procedures like vitrectomy. When the vitreous humor is compromised, it is essential to replace it with a vitreous substitute to alleviate any traction on the retina, which can help facilitate the healing process and allow for scar formation. During the procedure, the eye is prepared with anesthetic drops to minimize discomfort, and an antibacterial solution is applied to cleanse the surface of the eye. The physician identifies and marks a specific injection site in the pars plana or limbus area, which is critical for accessing the posterior segment of the eye. A small-gauge needle connected to a syringe filled with the vitreous substitute is then carefully inserted into the eye at the marked site. The vitreous substitute, which may consist of various substances such as gas (e.g., sulfur hexafluoride or n-perfluoropropane), air, or oil (e.g., polydimethylsiloxane), is injected to replace the lost vitreous humor. After the injection, the needle is withdrawn, and pressure is applied to the puncture site using a cotton-tipped applicator to prevent fluid leakage. Finally, antibiotic eye drops may be administered to reduce the risk of infection following the procedure.
