Fluorescein angiography and indocyanine-green angiography (includes multiframe imaging) performed at the same patient encounter with interpretation and report, unilateral or bilateral

Fluorescein angiography and indocyanine-green angiography are diagnostic imaging techniques used to visualize the blood vessels in the retina and choroid, respectively. Fluorescein angiography involves the injection of fluorescein dye into the bloodstream, which highlights the retinal blood vessels, allowing for the assessment of various retinal disorders. This technique is particularly useful in diagnosing conditions such as diabetic retinopathy, retinal vein occlusion, and other vascular abnormalities. On the other hand, indocyanine-green angiography utilizes indocyanine green dye, which fluoresces in the infrared spectrum, enabling the evaluation of the retina and choroid. This method is beneficial for detecting diseases like macular degeneration, abnormal vessel growth, macular edema, and retinal detachment, as it can penetrate through pigmentation and fluid in the eye. Prior to both procedures, mydriatic drops are administered to dilate the pupil, facilitating better visualization of the fundus. Following dilation, fundal photographs are captured before the dye infusion. A bolus of fluorescein or indocyanine green is injected into a peripheral vein, typically in the arm, and a series of photographs or video images are taken as the dye circulates through the blood vessels. The resulting images are analyzed by a 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. CPT® Code 92242 is specifically reported when both fluorescein angiography and indocyanine-green angiography are conducted during the same patient encounter, ensuring a thorough evaluation of the ocular structures involved.
