CPT® Code 67101

Retinal detachment is a serious ocular condition characterized by the separation of the retina from its underlying supportive tissue, the choroid. This separation can lead to significant visual impairment, including blurred vision, and if not addressed promptly, it may result in permanent blindness. The procedure described by CPT® Code 67101 involves the surgical repair of retinal detachment, which may include the drainage of subretinal fluid when necessary, as well as the application of cryotherapy. During the procedure, a lid speculum is utilized to hold the eyelids open, providing the surgeon with a clear view of the eye. Cryotherapy is a critical component of this repair, where a freezing probe is applied to the outer surface of the eye, specifically through the intact sclera, targeting the area of the retinal detachment. This technique involves creating a series of ice balls around the detachment site, which induces controlled freezing of the tissue. As the frozen area heals, scar tissue forms, effectively anchoring the retina back to the choroid. Additionally, if there is an accumulation of subretinal fluid, the surgeon may perform a drainage procedure by incising the sclera over the elevated retina and puncturing the choroid to allow the fluid to escape. This comprehensive approach aims to restore the normal anatomical position of the retina and preserve vision.
