CPT® Code 78707

The procedure described by CPT® Code 78707 involves the assessment of the kidneys' morphology, vascular flow, and function through a single imaging study that does not utilize pharmacological interventions. This imaging technique employs scintigraphy, which is a diagnostic method that uses a radiolabeled isotope tracer to visualize the kidneys. The kidneys play a crucial role in filtering waste from the bloodstream, maintaining chemical balance, and producing essential hormones such as erythropoietin, renin, and calcitriol. These hormones are vital for red blood cell production, blood pressure regulation, and calcium absorption, respectively. The procedure is particularly useful for evaluating various renal conditions, including renal blood flow issues, renovascular hypertension, renal cysts, tumors, abscesses, and overall kidney disease. Additionally, it can be employed to monitor the health and function of 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 emitted radioactive energy is converted into visual images for analysis. It is important to note that this specific code is applicable when the assessment is conducted without the administration of diuretics or ACE-inhibitor medications, which are used in other related codes for more detailed evaluations.
