How To Use CPT Code 36251

CPT 36251 describes the selective catheter placement for renal angiography, specifically targeting the main renal artery and any accessory renal artery(s). This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 36251?

CPT 36251 can be used to describe the procedure of selectively placing a catheter in the main renal artery and any accessory renal artery(s) for renal angiography. This code is used when the provider performs arterial puncture, catheter placement, fluoroscopy, contrast injection, image postprocessing, permanent recording of images, and radiological supervision and interpretation for the purpose of visualizing the renal blood vessels.

2. Official Description

The official description of CPT code 36251 is: ‘Selective catheter placement (first-order), main renal artery and any accessory renal artery(s) for renal angiography, including arterial puncture and catheter placement(s), fluoroscopy, contrast injection(s), image postprocessing, permanent recording of images, and radiological supervision and interpretation, including pressure gradient measurements when performed, and flush aortogram when performed; unilateral.’

3. Procedure

1. The provider begins by inserting a catheter into the femoral artery at the groin level.
2. Using fluoroscopic guidance, the provider navigates the catheter to the main renal artery and any accessory renal artery(s).
3. Once the catheter is in position, the provider injects a dye into the artery to visualize the renal blood vessels.
4. The provider takes X-ray images as the dye moves through the blood vessels, looking for any blockage, narrowing, or clots.
5. If necessary, the provider may perform pressure gradient measurements to assess the blood pressure at the renal artery.
6. If a flush aortogram is needed, the provider advances the catheter to the aorta and identifies any abnormalities in the X-ray images after contrast injection.
7. After completing the procedure, the provider removes the catheter and applies pressure to the puncture site to stop bleeding.
