The procedure identified by CPT® Code 78710 involves kidney imaging morphology through the use of tomographic techniques, specifically single photon emission computed tomography (SPECT). This imaging modality assesses the size, shape, and structural characteristics of the kidneys, which are vital organs responsible for filtering waste from the bloodstream, regulating chemical balances, and producing essential hormones such as erythropoietin, renin, and calcitriol. Erythropoietin is crucial for the production of red blood cells, renin plays a significant role in blood pressure regulation, and calcitriol is important for calcium absorption in the bones. The SPECT procedure utilizes a radiolabeled isotope tracer that is injected into the patient's circulatory system via an established intravenous line. This allows for the visualization of renal blood flow and the assessment of various renal conditions, including renovascular hypertension, renal cysts, tumors, abscesses, and kidney disease. Additionally, this imaging technique is instrumental in monitoring kidney transplants. During the procedure, the patient is positioned on an imaging table, and one or more gamma cameras rotate around the body to capture a three-dimensional view of the kidneys. The resulting images are processed and downloaded to a computer, where they can be viewed in tomographic sections or as a cinematic display. The physician then interprets the images and generates a comprehensive written report detailing the findings of the study.
