HCPCS G2170: Percutaneous Arteriovenous Fistula Creation Using Thermal Resistance Energy
HCPCS Level II code G2170 represents a percutaneous arteriovenous fistula (AVF) creation performed by direct tissue approximation using thermal resistance energy, including specified secondary procedures to redirect blood flow and associated imaging and guidance. This emerging interventional vascular technique matters nationally as an alternative to surgical AVF creation for patients requiring durable vascular access, with implications for outpatient interventional practice patterns, facility resource use, and payer coverage policies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for G2170, typical sites of service, and the scope of services captured by the code. The publication outlines benchmarks commonly tracked for novel interventional codes, summarizes relevant policy considerations for major payers, and highlights coding elements that affect claim composition and facility reporting. Where available, the report summarizes common use cases and procedural components included in the code definition; where specific comparative data or payer-specific coverage details are not provided in the input, the report notes that such data are not available in the input.
Intended for clinicians, coding professionals, and policy analysts, this piece provides the essential billing and clinical framing required to understand how G2170 fits into vascular access care pathways and payer interactions at a national level.
Billing Code Overview
HCPCS Level II code G2170 describes a percutaneous arteriovenous fistula (AVF) creation performed by direct tissue approximation using thermal resistance energy. The procedure includes any secondary procedures to redirect blood flow when performed (for example, transluminal balloon angioplasty or coil embolization) and encompasses all imaging and radiologic guidance, supervision and interpretation when performed.
Service type: Interventional vascular procedure — percutaneous AVF creation using thermal resistance energy with available adjunctive flow-redirecting procedures.
Typical site of service: Hospital outpatient department or ambulatory surgical center, where image-guided vascular interventions and endovascular therapies are commonly performed.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease on maintenance hemodialysis is evaluated for creation of a durable arteriovenous access. Prior surgical fistula attempts are limited by vascular anatomy and comorbidities. The interventionalist elects a percutaneous, image-guided creation of an arteriovenous fistula using thermal resistance energy to approximate artery and vein walls (G2170). The procedure is performed in an outpatient vascular/interventional radiology or ambulatory surgery setting with conscious sedation or monitored anesthesia care. Preprocedure workflow includes vascular mapping with duplex ultrasound, review of prior central venous catheters and clotting status, informed consent, and documentation of access site and laterality. Intra-procedure steps include ultrasound and fluoroscopic guidance, percutaneous arterial and venous access, device deployment to create the direct AVF by tissue approximation with thermal resistance energy, and any necessary secondary procedures to redirect flow (for example, transluminal balloon angioplasty or coil embolization). Imaging and radiologic supervision and interpretation are performed and documented. Postprocedure workflow includes access site hemostasis, postprocedure ultrasound or fistulogram to confirm flow and maturation potential, recovery monitoring, instruction for fistula care, and scheduling follow-up surveillance for maturation and dialysis use.
