CPT® Code 92287

Anterior segment imaging is a diagnostic procedure aimed at assessing the health and integrity of the cornea, iris, and other structures located in the anterior segment of the eye. This procedure is crucial for identifying potential abnormalities or diseases affecting these components, which are essential for maintaining clear vision. The cornea, which is the transparent front part of the eye, consists of multiple layers, including the epithelium, stroma, and a single layer of endothelial cells at the back. The endothelial layer plays a vital role in preserving visual acuity by regulating fluid balance within the cornea. It prevents aqueous humor from infiltrating the cornea and actively pumps excess fluid from the stroma into the anterior chamber, ensuring that the cornea remains in a dehydrated state necessary for clarity. However, endothelial cells are unique in that they do not regenerate; thus, if they are damaged due to disease or surgical intervention, the remaining cells must spread to cover a larger area. As the density of these cells diminishes, the endothelial layer loses its ability to maintain the cornea's dehydrated state, leading to corneal cloudiness and a subsequent decline in visual acuity. In the context of CPT® Code 92287, anterior segment imaging is enhanced through the use of fluorescein angiography. This technique involves the intravenous administration of sodium fluorescein, a dye that highlights the blood vessels in the anterior segment. Following the injection, a series of images are captured, starting approximately 8 to 10 seconds post-injection and continuing for up to one minute, with additional images potentially taken 5 to 10 minutes later. The resulting images are analyzed, and a comprehensive written interpretation of the findings is generated, providing valuable insights into the condition of the iris and other anterior segment structures.
