CPT® Code 67516

The CPT® Code 67516 refers to the procedure of a suprachoroidal space injection of a pharmacologic agent, which is classified as a separate procedure. This technique is primarily utilized to address various diseases affecting the posterior segment of the eye, which includes critical structures such as the retina, macula, and optic nerve. Common conditions treated with this injection include age-related macular degeneration, retinal vein occlusion, and diabetic macular edema. The suprachoroidal space itself is a narrow anatomical area located between the choroid and the sclera, extending from the limbus (the border between the cornea and the sclera) to the optic nerve. This space is characterized by a defined inner layer of the choroid known as Bruch's membrane, along with an outer transition zone that consists of several fibrous lamellae of varying thickness, which are situated close to the sclera. During the procedure, a specialized handheld microinjector, which consists of a syringe and a very fine needle, is employed to deliver the pharmacologic agent. The needle is carefully inserted through the sclera, allowing the fluid to be injected into the posterior segment of the eye, where it subsequently disperses around the globe and throughout the choroid and retina, facilitating targeted treatment of the underlying conditions.
