CPT® Code 78710

Deleted

1. Indications

The procedure coded as CPT® 78710 is indicated for various clinical scenarios related to kidney function and morphology. The following conditions may warrant the use of this imaging technique:

• Renal Blood Flow Evaluation This procedure is utilized to assess the blood flow to the kidneys, which is essential for understanding renal function and diagnosing potential vascular issues.
• Renovascular Hypertension SPECT imaging can help identify causes of high blood pressure that may be related to renal artery stenosis or other vascular abnormalities affecting the kidneys.
• Renal Cysts The presence of cysts in the kidneys can be evaluated through this imaging technique to determine their size, number, and potential complications.
• Tumors The procedure is used to detect and characterize renal tumors, aiding in the diagnosis and management of renal cancer.
• Abscesses SPECT imaging can assist in identifying renal abscesses, which are localized infections that may require further intervention.
• Kidney Disease This imaging modality is beneficial in the assessment of various forms of kidney disease, providing insights into the structural and functional status of the kidneys.
• Monitoring Kidney Transplants The procedure is also indicated for the ongoing evaluation of kidney transplant function, helping to ensure the transplanted organ is functioning properly.

2. Procedure

The procedure for CPT® Code 78710 involves several key steps that ensure accurate imaging of the kidneys. The following outlines the procedural steps:

• Step 1: Establishing an Intravenous Line The first step in the procedure is to establish an intravenous (IV) line in the patient’s arm or hand. This IV line is crucial for administering the radiolabeled isotope tracer, which is necessary for the imaging process.
• Step 2: Injection of Radiolabeled Isotope Tracer Once the IV line is in place, a radiolabeled isotope tracer is injected directly into the patient’s circulatory system. This tracer is essential for visualizing kidney function and morphology during the imaging process.
• Step 3: Positioning the Patient After the injection, the patient is positioned on the imaging table, ensuring they are comfortable and properly aligned for optimal imaging results.
• Step 4: Imaging with Gamma Cameras One or more gamma cameras are then utilized to rotate around the patient’s body. These cameras capture images of the kidneys from multiple angles, allowing for a comprehensive three-dimensional view of the renal structures.
• Step 5: Image Processing The images obtained from the gamma cameras are downloaded to a computer system. The images can be viewed in tomographic sections, which provide detailed cross-sectional views of the kidneys, or as a cinematic display for a more dynamic representation.
• Step 6: Interpretation and Reporting Finally, a physician interprets the images generated from the SPECT procedure. The physician analyzes the findings and compiles a written report that details the results of the imaging study, which is then communicated to the referring healthcare provider.

3. Post-Procedure

After the completion of the SPECT imaging procedure, patients are typically monitored for a short period to ensure there are no immediate adverse reactions to the radiolabeled isotope tracer. Patients may be advised to drink plenty of fluids to help flush the tracer from their system. There are generally no significant restrictions on activities following the procedure, and patients can usually resume their normal daily activities unless otherwise instructed by their healthcare provider. The physician will provide the patient with the results of the imaging study in a timely manner, along with any necessary follow-up recommendations based on the findings.
