CPT Code Overview

CPT code 36902 describes the introduction of needle(s) and/or catheter(s) into a dialysis circuit, accompanied by diagnostic angiography and transluminal balloon angioplasty of the peripheral dialysis segment. This procedure includes all direct punctures, catheter placements, injections of contrast, and necessary imaging from the arterial anastomosis and adjacent artery through the entire venous outflow, including the inferior or superior vena cava. It also encompasses fluoroscopic guidance, radiological supervision and interpretation, image documentation, and reporting. The service type is Surgical Procedures on Arteries and Veins, and it is most commonly performed in an Outpatient Hospital (POS 22) setting.

Clinical Context

A typical patient scenario involves an individual with end stage renal disease who is dependent on hemodialysis via a vascular access circuit, such as an arteriovenous (AV) fistula or graft. The patient presents with signs of access dysfunction, such as decreased dialysis flow rates or abnormal physical findings suggesting stenosis or stricture within the dialysis circuit. The clinical workflow includes evaluation by a vascular surgeon or interventional radiologist, followed by percutaneous access to the circuit. Diagnostic angiography is performed to assess the entire circuit, and if a peripheral segment stenosis is identified, transluminal balloon angioplasty is carried out to restore patency. Imaging and radiological supervision are integral throughout the procedure, and a formal report is generated documenting the findings and intervention.

Coding Specifications

• Modifiers:

  • 26 - Professional Component: Used when only the physician's interpretation and report are billed, not the technical portion.
  • TC - Technical Component: Used when only the technical portion (equipment, supplies, staff) is billed.
  • 59 - Distinct Procedural Service: Used to indicate that a procedure or service is distinct or independent from other services performed on the same day.
  • LT - Left Side: Used to specify that the procedure was performed on the left side of the body.

• Provider Taxonomies:

These taxonomies represent providers specializing in vascular surgery, cardiothoracic vascular surgery, and vascular/interventional radiology, all of whom may perform this procedure.

Related Diagnoses

• T82.858A: Stenosis of vascular prosthetic devices, implants and grafts, initial encounter

  • Relevant for patients with AV grafts experiencing narrowing or blockage, often necessitating angioplasty.

• I77.1: Stricture of artery

  • Indicates arterial narrowing, which may affect the dialysis circuit and require intervention.

• N18.6: End stage renal disease

  • The underlying condition for patients requiring dialysis and vascular access procedures.

• Z99.2: Dependence on renal dialysis

  • Used to document the patient's reliance on dialysis, supporting the medical necessity for access maintenance.

• I70.92: Atherosclerosis of unspecified type of bypass graft(s) of the extremities

  • Reflects vascular disease affecting grafts, which can lead to stenosis and require angioplasty.

Each diagnosis code is clinically relevant to the procedure described by 36902, as they represent conditions commonly encountered in patients with dialysis access dysfunction.

Related CPT Codes

• 36901: Introduction of needle(s) and/or catheter(s), dialysis circuit, with diagnostic angiography only. This code is used when only diagnostic imaging is performed without intervention.

• 36903: Similar to 36902, but includes intravascular stent placement(s) in the peripheral dialysis segment. Used when a stent is placed after angioplasty.

• 36904: Percutaneous transluminal mechanical thrombectomy and/or infusion for thrombolysis, dialysis circuit, any method, including all imaging and radiological supervision and interpretation, diagnostic angiography, fluoroscopic guidance, catheter placement(s), and intraprocedural pharmacological thrombolytic injection(s). Used when thrombectomy or thrombolysis is performed in addition to angioplasty.

• 36905: Similar to 36904, used for more extensive thrombectomy or thrombolysis procedures.

• 36907: Obstructed central segment dialysis circuit angioplasty by balloon, with radiological supervision and interpretation included. Used when angioplasty is performed in the central segment of the dialysis circuit.

These codes are related to 36902 and may be used as alternatives or in combination, depending on the clinical findings and interventions required during the procedure. For example, 36901 may precede 36902 if only diagnostic imaging is initially performed, while 36903 may follow if stent placement is necessary. 36904 and 36905 are used when thrombectomy or thrombolysis is indicated, and 36907 is specific to central segment angioplasty.

Medicare's national mean rate for CPT code 36902 is $1,240.75, which is higher than the BUCA (Blue Cross Blue Shield, UnitedHealth Group, Cigna, and Aetna) average commercial mean rate of $1,077.76. Among commercial payers, UnitedHealth Group stands out with the highest mean rate at $1,633.62, while Aetna has the lowest at $774.55.

Rate dispersion, measured by the difference between the 75th and 25th percentiles, varies significantly across payers. UnitedHealth Group exhibits the widest spread ($820.50), indicating greater variability in rates, while Medicare has the tightest range ($154.00), reflecting more consistent reimbursement levels. Aetna also shows a relatively narrow range ($378.50), compared to other commercial payers.
