Summary & Overview
CPT 36908: Intravascular Stent Placement for Dialysis Circuit
CPT code 36908 represents intravascular stent placement performed during a primary procedure on a dialysis circuit to treat an obstructed central segment. The code includes radiological supervision and interpretation for any imaging necessary to complete the intravascular stent placement. This procedure is clinically significant because maintaining dialysis circuit patency reduces access failure, preserves dialysis adequacy, and can lower the need for additional interventions.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of clinical context, common sites of service, typical application during dialysis access procedures, and the relevance of included radiology services. The publication summarizes benchmarking and reimbursement considerations, outlines common billing modifiers that may apply, and highlights policy or coding clarifications affecting coverage and claims processing. It also identifies areas where input data was not provided, such as associated taxonomies, ICD-10 diagnosis mappings, and related codes, so readers understand where additional clinical or administrative details may be needed.
Billing Code Overview
CPT code 36908 describes intravascular stent placement performed during a primary procedure on a patient's dialysis circuit when an obstructed central segment is encountered. The provider dilates the obstructed segment and then places a stent through a catheter into the vessel lumen to maintain patency. Radiological supervision and interpretation for imaging required to perform the stent placement is included with this code.
-
Service type: Endovascular stent placement during dialysis circuit intervention
-
Typical site of service: Hospital-based interventional radiology suite or outpatient vascular access/interventional facility
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease presents for maintenance of a functioning arteriovenous dialysis circuit. During a primary dialysis circuit procedure for suspected circuit dysfunction the interventionalist identifies an obstructed central segment (e.g., central venous stenosis or occlusion) that impairs dialysis flow. Under conscious sedation in an interventional radiology or vascular access suite, the provider performs angiography to define the lesion, uses balloon angioplasty to dilate the stenotic segment, and deploys an intravascular stent through a catheter into the vessel lumen to maintain diameter and restore blood flow. Radiological supervision and interpretation for fluoroscopic imaging is used throughout the procedure and is included in the service. Typical sites of service include an outpatient interventional radiology suite, hospital-based interventional lab, or ambulatory surgical center. The clinical workflow includes pre-procedure evaluation, vascular access, intraprocedural imaging and intervention (angioplasty and stent placement), post-deployment angiographic confirmation of patency, hemostasis, recovery monitoring, and discharge with instructions for dialysis access surveillance.
