Summary & Overview
CPT 0237T: Brachiocephalic Trunk Plaque Removal, Open or Percutaneous
CPT code 0237T denotes a procedure to restore blood flow through the brachiocephalic trunk and its branches by removing deposited plaque via open or percutaneous techniques. This vascular intervention targets major proximal arterial obstruction that can compromise cerebral and upper extremity perfusion. As an emerging or specialized vascular service, accurate coding supports clinical documentation, appropriate site-of-service designation, and payer adjudication nationally.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical service settings, and payer coverage considerations. The publication summarizes benchmarking elements, common modifiers and billing practices, and highlights policy updates or documentation points that influence claims processing.
The report provides: (1) a clear definition of the clinical service represented by 0237T; (2) expected places of service and clinical rationale for the intervention; (3) payer-specific coverage and coding considerations; and (4) items to verify in documentation to support medical necessity and claim validation. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 0237T describes a procedure to restore blood flow in a narrowed or blocked segment of the brachiocephalic trunk and its branches. The provider removes atherosclerotic plaque using either an open surgical or a percutaneous endovascular approach to re-establish perfusion to the affected vessels.
Service Type: Vascular surgical or endovascular plaque removal (brachiocephalic trunk and branches)
Typical Site of Service: Hospital inpatient or outpatient surgical setting, or hospital-based interventional radiology/catheterization laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old male with progressive right-sided arm claudication, episodic dizziness, and findings of differential blood pressures between the arms. Noninvasive testing (duplex ultrasound, CTA) demonstrates high-grade atherosclerotic stenosis of the brachiocephalic trunk originating at its ostium. The vascular surgeon or interventionalist evaluates the patient in clinic, reviews imaging, and discusses revascularization options. The procedure 0237T is performed in an operating room or interventional suite under conscious sedation or general anesthesia. The workflow includes preoperative consent, vascular access (open cervical or percutaneous femoral/axillary approach), angiography to confirm lesion anatomy, plaque removal via endarterectomy or percutaneous thrombectomy/atherectomy as appropriate, vessel repair (patch angioplasty or stent placement if needed), hemostasis, and post-procedure monitoring in a post-anesthesia care unit or step-down vascular recovery area. Typical perioperative documentation includes procedural indication, intraoperative findings, technique (open versus percutaneous), devices used, estimated blood loss, complications, and discharge or admission plan for observation or inpatient care.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier — standard reporting | Use when no special circumstances or modifiers apply. |
22 | Increased procedural services | Use when work required is substantially greater than typically required (document rationale). |
23 | Unusual anesthesia — medically necessary | Use if the procedure is performed under general anesthesia when local/regional would ordinarily be used due to medical necessity. |
50 | Bilateral procedure | Use when bilateral brachiocephalic territory procedures are performed (rare; use per payer guidance). |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned. |
53 | Discontinued procedure | Use when procedure is started but terminated due to extenuating circumstances. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team approach | Use when a surgical team approach is required and documented. |
78 | Return to OR for related procedure during global period | Use if the patient returns to the OR for a related procedure during the global surgical period. |
80 | Assistant surgeon | Use when an assistant surgeon provides intraoperative assistance and documentation supports payment. |
81 | Minimum assistant surgeon | Use when minimal assistant presence is documented and applicable. |
82 | Assistant surgeon when qualified resident not available | Use when an assistant surgeon is used because a qualified resident is unavailable. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist service | Use when services are furnished by these nonphysician practitioners per payer rules. |
TC | Technical component | Use when reporting only the technical component (imaging/technical aspects) if split billing is allowed. |
