CPT® Code 68362

The procedure described by CPT® Code 68362 involves the creation of a total conjunctival flap, which is a surgical technique used primarily for the treatment of corneal ulcers. This procedure is essential in cases where the cornea has sustained significant damage, necessitating a more extensive approach than a partial flap. The conjunctival flap serves to cover the entire cornea, providing a protective layer that promotes healing and restores the integrity of the ocular surface. The term "Gunderson thin flap" is often associated with this technique, indicating a specific method of flap preparation that optimizes the use of conjunctival tissue. The procedure begins with the administration of anesthetic eye drops to ensure patient comfort, followed by the insertion of an eye speculum to maintain an open field for surgery. The surgeon then excises any diseased tissue, evaluates the size and location of the corneal defect, and determines the best configuration for the flap. This meticulous planning is crucial for the success of the procedure, as it ensures that the flap will adequately cover the affected area while preserving its blood supply. The total conjunctival flap is secured to the lower limbal conjunctiva, effectively covering the entire cornea and facilitating the healing process.
