CPT® Code 78700

The procedure described by CPT® Code 78700 involves kidney imaging morphology, which focuses on assessing the size, shape, and structural characteristics of the kidneys, as well as their functional capabilities. This assessment is conducted using scintigraphy, a diagnostic imaging technique that employs a radiolabeled isotope tracer to visualize the kidneys. The kidneys play a crucial role in filtering waste products from the bloodstream, maintaining chemical balance, and producing essential hormones such as erythropoietin, which is vital for red blood cell production; renin, which helps regulate blood pressure; and calcitriol, which is important for calcium absorption in the bones. The imaging procedure is particularly useful for evaluating various renal conditions, including renal blood flow issues, renovascular hypertension, the presence of renal cysts, tumors, abscesses, and other kidney diseases. Additionally, it serves as a monitoring tool for kidney transplants. During the procedure, an intravenous line is established to facilitate the injection of the radiolabeled isotope tracer directly into the patient's circulatory system. The patient is then positioned on an imaging table, where a gamma camera is focused on the kidneys to capture images. Scanning occurs at predetermined intervals, and the radioactive energy emitted from the kidneys is converted into detailed images for analysis. It is important to note that CPT® Code 78700 is specifically utilized when the focus is solely on the morphology of the kidneys, whereas CPT® Code 78701 is applicable when both morphology and vascular flow are evaluated. Following the imaging, the physician interprets the results and generates a comprehensive written report detailing the findings of the study.
