HCPCS C7514: Central Dialysis Segment Angioplasty with Stent Placement

HCPCS Level II code C7514 designates a complex interventional radiology procedure performed through a dialysis circuit that combines diagnostic angiography, fluoroscopic guidance, angioplasty of the central dialysis segment, and transcatheter placement of intravascular stents. The code is used when comprehensive imaging—from the arterial anastomosis through the full venous outflow including the superior or inferior vena cava—is required along with catheter placement and contrast injection. Nationally, this code captures high-acuity vascular access interventions that are integral to maintaining hemodialysis function and reducing access-related morbidity.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service represented by C7514, guidance on typical sites of service, and the types of procedural components bundled under this code. The publication also summarizes common billing considerations and associated practice patterns relevant to facilities and interventional radiology teams. Data not available in the input are explicitly noted where applicable. This resource is intended to clarify the clinical and billing scope of C7514 for national stakeholders in vascular access care and revenue integrity.

Billing Code Overview

HCPCS Level II code C7514 describes the introduction of needle(s) and/or catheter(s) into a dialysis circuit with diagnostic angiography of the dialysis circuit, including direct punctures and catheter placements, contrast injections, and comprehensive imaging from the arterial anastomosis and adjacent artery through the entire venous outflow to the inferior or superior vena cava. The procedure includes fluoroscopic guidance, angioplasty in the central dialysis segment, and transcatheter placement of intravascular stent(s) in the central dialysis segment, performed through the dialysis circuit. This service also encompasses required imaging, radiological supervision and interpretation, image documentation, and reporting.

Service Type: Interventional radiology procedure combining diagnostic angiography, angioplasty, and transcatheter stent placement of the central dialysis segment performed via the dialysis circuit
Typical Site of Service: Hospital outpatient department or ambulatory surgery center where advanced fluoroscopic and interventional radiology capabilities are available

Clinical & Coding Specifications

Clinical Context

A 62-year-old patient with end-stage renal disease (ESRD) on maintenance hemodialysis via a tunneled central venous dialysis catheter presents with progressive difficulty achieving adequate dialysis flow and elevated venous pressures during treatments. Duplex ultrasound suggests central venous outflow obstruction and the dialysis team documents recurrent catheter dysfunction despite thrombolytic attempts. The vascular interventional team schedules a procedure to access the dialysis circuit, perform diagnostic angiography of the arterial anastomosis through the entire venous outflow (including the superior or inferior vena cava as indicated), treat focal central dialysis segment stenosis with angioplasty, and deploy an intravascular stent if required.

The clinical workflow includes pre-procedure review of prior imaging and labs, informed consent, sterile field setup in an angiography suite, percutaneous introduction of needles/catheters through the dialysis circuit, fluoroscopically guided diagnostic angiography from arterial anastomosis through venous outflow, targeted balloon angioplasty of central dialysis segment lesions, transcatheter stent placement when residual stenosis or elastic recoil persists, completion angiography documenting technical success, radiological supervision and interpretation, image documentation, and post-procedure monitoring with dialysis unit communication for future access management.
