Summary & Overview
CPT 0234T: Renal Artery Revascularization with Plaque Removal
CPT code 0234T represents renal artery revascularization with plaque removal performed by open surgical or percutaneous techniques to restore renal blood flow. This procedure addresses hemodynamically significant renal artery stenosis that can contribute to hypertension and renal dysfunction. Nationally, the code is relevant for hospitals and interventional practices managing vascular disease and impacts facility and physician billing for complex endovascular or surgical renal interventions.
Key payers in a national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for renal artery plaque removal, typical sites of service, and which payers commonly cover such procedures. The publication also outlines expected benchmarks and utilization patterns, summarizes recent policy updates affecting coverage and coding practice, and highlights coding nuances that affect claim submission and reimbursement across payers.
This summary is intended to orient clinical administrators, billing professionals, and policy analysts to the purpose and billing context of CPT code 0234T, providing a foundation for deeper review of payer-specific policies, reimbursement benchmarks, and clinical documentation requirements.
Billing Code Overview
CPT code 0234T describes a procedure to restore blood flow in a narrowed or blocked renal artery by removing deposited plaque. The service can be performed via an open surgical approach or percutaneously and involves re-establishing adequate renal arterial perfusion.
-
Service type: Vascular interventional or surgical revascularization of the renal artery
-
Typical site of service: Hospital operating room, hybrid operating suite, or interventional radiology/cardiac catheterization laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old with long-standing hypertension and worsening renal function who presents with refractory hypertension and unexplained decline in estimated glomerular filtration rate (eGFR). Imaging (renal duplex ultrasound, CT angiography, or MR angiography) demonstrates a hemodynamically significant ostial narrowing of the renal artery consistent with atherosclerotic renal artery stenosis. After multidisciplinary review, the vascular surgeon or interventional radiologist schedules revascularization via percutaneous transluminal renal angioplasty with atherectomy or stent placement to restore renal perfusion and control blood pressure.
The clinical workflow includes pre-procedure evaluation (medical optimization, medication reconciliation, contrast allergy assessment, informed consent), intraprocedural vascular access (commonly femoral or radial), angiography to confirm lesion characteristics, plaque removal or debulking via atherectomy or mechanical thrombectomy as indicated, adjunctive balloon angioplasty and possible stent deployment, completion angiography to document flow restoration, hemostasis and postoperative monitoring for contrast nephropathy, access-site complications, and blood pressure/renal function follow-up. Typical care teams include vascular surgery, interventional radiology, anesthesiology (conscious sedation or general anesthesia if required), nursing, and radiology technologists. Typical site of service is an ambulatory surgery center or hospital outpatient department with endovascular capability; inpatient admission occurs when complications or comorbidities require overnight observation or staged care.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, or technical difficulty substantially exceeds usual expectations and documentation supports increased complexity for 0234T. |
23 | Unusual anesthesia | Use when procedure is performed under general anesthesia in an otherwise local/regional setting and anesthesia was medically necessary. |
50 | Bilateral procedure | Use if both renal arteries are treated during the same operative session and payer allows bilateral modifier application. |
51 | Multiple procedures | Use when 0234T is billed with other unrelated procedures in the same session where multiple-procedure reductions may apply. |
52 | Reduced services | Use when an attempted atherectomy/endarterectomy is started but not completed, documented as reduced service. |
53 | Discontinued procedure | Use when procedure is terminated for patient safety before completion; document reason. |
62 | Two surgeons | Use when two surgeons of different specialties perform distinct portions of the procedure concurrently. |
66 | Surgical team | Use when a surgical team approach is used and supported by payer policy. |
78 | Return to OR for related procedure | Use when a related procedure addressing a complication is performed during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon provides intraoperative assistance and payer accepts the modifier. |
81 | Minimum assistant surgeon | Use when minimal assistance is provided by a second surgeon. |
82 | Assistant surgeon when qualified resident not available | Use when no qualified resident is available and an assistant surgeon is required. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist | Use when an advanced practice clinician performs portions of the service per scope and payer rules. |
TC | Technical component | Use when separate reporting of imaging or device technical components applies; commonly appended to associated imaging codes, not to 0234T which is a procedure code. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RP0000X | Vascular Surgery | Primary specialty performing open or endovascular renal artery interventions. |
2085P0200X | Interventional Cardiology | Performs catheter-based renal interventions in some centers. |
2084P0200X | Interventional Radiology | Common provider for percutaneous renal artery plaque removal and angioplasty/stent placement. |
208D00000X | Diagnostic Radiology | Provides diagnostic angiography and image guidance support. |
Related Diagnoses

I77.1 | Stricture of artery | Describes arterial narrowing that may be an indication for revascularization of the renal artery. |
I12.0 | Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease | Renal artery stenosis can cause or worsen hypertension and CKD; this diagnosis often coexists and drives intervention decisions. |

N28.9 | Disorder of kidney and ureter, unspecified | Used when a more specific renal diagnosis is not coded but renal dysfunction is present and related to vascular disease. |
