CPT® Code 65782

The procedure described by CPT® Code 65782 is known as ocular surface reconstruction through a limbal conjunctival autograft, which includes the process of obtaining the graft itself. This surgical intervention is specifically designed to address significant damage to the cornea, which may arise from various injuries or disease processes that compromise the eye's ability to heal naturally. The limbus, which is the white outer edge of the eyeball, plays a crucial role in this procedure as it houses stem cells responsible for generating corneal epithelial cells. These cells are vital for forming the outermost protective layer of the cornea, which serves as a barrier against pathogens and environmental contaminants. In cases where only one eye is affected, the surgeon will harvest a graft from the patient's healthy eye, ensuring that the donor site is minimally invasive. The procedure involves careful preparation of the damaged eye, including debridement of the corneal epithelium to eliminate unhealthy stem cells and creating a suitable transplant bed. The surgical technique requires precision in resecting the conjunctiva and exposing the sclera, followed by the placement of the graft, which is then secured with sutures. Post-operative care includes the application of antibiotic and corticosteroid ointments to promote healing and prevent infection, along with protective measures such as patching the eye and using an eye shield to safeguard the surgical site during recovery.
