CPT® Code 0473T

Device evaluation and interrogation of intraocular retinal electrode array (eg, retinal prosthesis), in person, including reprogramming and visual training, when performed, with review and report by a qualified health care professional

The CPT® Code 0473T refers to the process of evaluating and interrogating an intraocular retinal electrode array, commonly known as a retinal prosthesis. This procedure is performed in person and includes essential components such as reprogramming the device and providing visual training, if applicable. The retinal prosthesis is designed to address profound vision loss by delivering electrical impulses to stimulate secondary nerve cells along the visual pathway. This stimulation is achieved through a micro-photodiode array or micro-electrode array, which can be placed either epiretinally or subretinally. The primary indications for this procedure include conditions such as retinitis pigmentosa and age-related macular degeneration, which are known to cause significant vision impairment. The evaluation and interrogation process involves a thorough review and report by a qualified healthcare professional, ensuring that the device is functioning optimally and that the patient receives appropriate visual training to maximize the benefits of the prosthesis.
