CPT® Code 65436

The procedure described by CPT® Code 65436 involves the removal of the corneal epithelium, which is the outermost layer of the cornea, a transparent front part of the eye. This procedure is typically indicated for patients with conditions that have led to the deterioration or damage of the corneal epithelium, such as disease, erosion, or dystrophy. The removal process can be performed using various techniques, including abrasion or curettage, which involve scraping or brushing away the epithelial layer. The goal of this procedure is to eliminate unhealthy or compromised epithelial tissue to promote healing and restore corneal integrity. Following the removal of the epithelium, a chelating agent, such as ethylenediaminetetraacetic acid (EDTA), is applied to the exposed underlying tissue. This chemical application serves to cauterize the area and may assist in the removal of any calcifications or deposits that may have formed on the Bowman's layer, which lies beneath the epithelium. The procedure is performed with precision, utilizing instruments such as sponges or blades for the epithelial removal and surgical sponges or specialized reservoirs for the application of the chelating agent.
