CPT® Code 65426

The procedure described by CPT® Code 65426 involves the excision or transposition of a pterygium, which is a growth of conjunctival tissue that can extend onto the sclera and potentially invade the cornea. This condition is characterized by a raised, triangular appearance at the corner of the eye. The surgical intervention is necessary when the pterygium encroaches upon the central cornea, as it can lead to vision impairment and discomfort. In this specific procedure, the physician not only removes the pterygium but also addresses the resulting defect in the sclera by employing a graft. The excision is performed meticulously, ensuring that the pterygium is dissected down to the level of Tenon's capsule, which is a layer of tissue surrounding the eye. Following the removal of the pterygium, a graft is utilized to repair the defect left behind. This graft can be an autograft, taken from the patient's own conjunctiva, or an allograft, such as an amniotic membrane obtained from a tissue bank. The graft is then secured in place, either through suturing or the application of fibrin tissue glue, to promote healing and restore the integrity of the conjunctival surface.
