CPT® Code 65450

The CPT® Code 65450 refers to the procedure for the destruction of a lesion on the cornea using various techniques, including cryotherapy, photocoagulation, or thermocauterization. In this context, a lesion is an abnormal area on the cornea, which is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The procedure begins with the instillation of eye drops to numb the eye, ensuring patient comfort during the intervention. Cryotherapy involves the application of a freezing probe directly to the lesion, where the extreme cold effectively destroys the targeted tissue. Alternatively, photocoagulation utilizes a focused laser beam directed at the cornea, which precisely destroys the lesion through the application of light energy. Lastly, thermocauterization is a method that involves the use of a heat probe that makes contact with the lesion, effectively burning and destroying the abnormal tissue. Each of these techniques is designed to eliminate the lesion while preserving surrounding healthy corneal tissue, thereby maintaining the integrity of the eye's structure and function.
