CPT® Code 92240

Indocyanine-green angiography, designated by CPT® Code 92240, is a diagnostic imaging procedure that utilizes indocyanine green dye to visualize the blood vessels in the retina and choroid. This technique is particularly valuable in the assessment of various retinal diseases, including macular degeneration, abnormal vessel growth, macular edema, and retinal detachment. The indocyanine green dye fluoresces in the infrared spectrum, enabling detailed imaging even in the presence of pigmentation, fluid, or blood collections within the retina and choroid. Prior to the procedure, the patient's pupils are dilated using mydriatic drops to facilitate optimal imaging. Fundal photographs are captured before the dye infusion to establish a baseline. Following the dilation, a bolus of indocyanine green is injected into a peripheral vein, typically in the arm. As the dye circulates, rapid sequence or video imaging is employed to capture the flow of the dye through the retinal and choroidal blood vessels. The resulting images are meticulously analyzed by the physician, who identifies any abnormalities present in the retina or choroid. A comprehensive written report detailing the findings is generated, which may pertain to one eye or both eyes. It is important to note that if both fluorescein angiography and indocyanine-green angiography are conducted during the same patient visit, CPT® Code 92242 should be reported in conjunction with this procedure.
