Summary & Overview
CPT 36905: Percutaneous Mechanical Thrombectomy for Dialysis Circuit
CPT code 36905 is a critical billing code for percutaneous transluminal mechanical thrombectomy and/or infusion for thrombolysis in dialysis circuits. This procedure is essential for maintaining the functionality of dialysis access, which is vital for patients undergoing regular dialysis treatments. The code encompasses all aspects of the intervention, including imaging, radiological supervision, diagnostic angiography, fluoroscopic guidance, catheter placements, and intraprocedural pharmacological thrombolytic injections.
Nationally, this code is recognized by major payers such as Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare, reflecting its widespread clinical and billing relevance. The procedure is typically performed in outpatient hospital settings, aligning with current standards for dialysis circuit interventions.
Readers will gain insight into the clinical context of CPT 36905, including its role in dialysis circuit maintenance, payer coverage, and associated benchmarks. The publication also highlights policy updates and billing considerations relevant to vascular surgery, urology, and interventional radiology specialties. Understanding this code is crucial for stakeholders involved in dialysis care, medical billing, and healthcare policy, as it impacts reimbursement, compliance, and patient access to essential vascular procedures.
CPT Code Overview
CPT 36905 describes a percutaneous transluminal mechanical thrombectomy and/or infusion for thrombolysis in a dialysis circuit. This procedure involves the removal of blood clots or thrombus from the dialysis access circuit using any method, and includes all imaging and radiological supervision and interpretation, diagnostic angiography, fluoroscopic guidance, catheter placement(s), and intraprocedural pharmacological thrombolytic injection(s).
Service Type: Dialysis Circuit Procedures
Typical Site of Service: Outpatient Hospital (POS 22)
Clinical & Coding Specifications
Clinical Context
A patient with a dialysis circuit (such as an arteriovenous fistula or graft) presents to the outpatient hospital setting with symptoms of circuit dysfunction, such as decreased flow or clot formation. The clinical workflow involves evaluation by a vascular surgery, urology, or interventional radiology physician. Imaging is performed to assess the circuit, and a percutaneous transluminal mechanical thrombectomy and/or infusion for thrombolysis is carried out to remove thrombus and restore patency. The procedure includes all necessary imaging, radiological supervision, diagnostic angiography, fluoroscopic guidance, catheter placements, and intraprocedural pharmacological thrombolytic injections as needed. The patient is monitored post-procedure for circuit function and potential complications.

National Reimbursement Benchmarks
Medicare's national mean rate for CPT 36905 is $2,297.85, which is higher than Aetna, Blue Cross Blue Shield, and BUCA (average commercial), but lower than Cigna and UnitedHealth Group. BUCA's mean rate stands at $2,043.12, reflecting the average commercial reimbursement across major payers.
Rate dispersion varies significantly among payers. Aetna has the tightest range between the 25th and 75th percentiles ($697.35), indicating less variability in contracted rates. UnitedHealth Group exhibits the widest dispersion ($1,548.67), suggesting greater variability in rates across providers.
