CPT® Code 0017T

Deleted

The CPT® Code 0017T refers to the procedure known as the destruction of macular drusen through photocoagulation. Macular drusen are small yellow or white accumulations of extracellular material that develop between the retina and the retinal pigment epithelium, often associated with age-related macular degeneration (AMD). These drusen can lead to vision impairment by affecting the retinal pigment epithelium, which is crucial for the health of photoreceptors in the retina. The procedure involves the use of a laser to precisely target and destroy these drusen, thereby potentially improving or stabilizing vision. During the procedure, the ophthalmologist carefully administers photocoagulation, ensuring that the fovea—the central part of the retina responsible for sharp vision—is avoided to minimize the risk of damage to this critical area. This technique is particularly important in managing patients with AMD, as it aims to reduce the progression of the disease and preserve visual function.
