The procedure described by CPT® Code 0124T involves a conjunctival incision with posterior extrascleral placement of a pharmacological agent. This technique is primarily utilized in the treatment of age-related macular degeneration (AMD), a condition characterized by the deterioration of the central portion of the retina, leading to vision loss. The pharmacological agent typically used in this procedure is a depot suspension of an angiostatic cortisene, which plays a crucial role in inhibiting ocular neovascularization—a common complication associated with AMD. By preventing the proteolysis necessary for the migration of vascular endothelial cells, the angiostatic cortisene helps to mitigate the progression of abnormal blood vessel growth in the eye. The procedure begins with a careful incision in the conjunctiva, allowing access to the underlying Tenons capsule and the sclera. The use of a blunt-tipped, curved cannula facilitates the precise placement of the pharmacological agent in the extrascleral space, ensuring that it is delivered effectively near the macula. This method is designed to optimize the therapeutic effects of the medication while minimizing potential complications associated with direct scleral incision.
