CPT® Code 36901

Introduction of needle(s) and/or catheter(s), dialysis circuit, with diagnostic angiography of the dialysis circuit, including all direct puncture(s) and catheter placement(s), injection(s) of contrast, all necessary imaging from the arterial anastomosis and adjacent artery through entire venous outflow including the inferior or superior vena cava, fluoroscopic guidance, radiological supervision and interpretation and image documentation and report;

The procedure described by CPT® Code 36901 involves the introduction of needle(s) and/or catheter(s) into the dialysis circuit, accompanied by diagnostic angiography. This process is essential for visualizing the hemodialysis circuit, which may include various components such as a central venous catheter (CVC), an arteriovenous (AV) fistula, or a synthetic AV graft. The primary goal of this procedure is to assess the dialysis circuit for any stenosis or obstruction that could lead to complications such as low blood flow, elevated pre-pump arterial pressure, or high venous return pressure. The procedure begins with the insertion of a needle into the dialysis access point, followed by the placement of a catheter to facilitate the injection of contrast dye. This dye allows for detailed imaging of the arterial anastomosis and adjacent artery, extending through the entire venous outflow, including the inferior or superior vena cava. The use of fluoroscopic guidance ensures accurate placement and visualization during the procedure, while radiological supervision and interpretation are critical for generating a comprehensive report of the findings. This thorough approach is vital for diagnosing issues within the dialysis circuit and determining the appropriate interventions, such as balloon angioplasty or stent placement, if necessary.
