Summary & Overview
CPT 00350: Anesthesia for Major Vessels of the Neck, Unspecified
CPT code 00350 designates anesthesia services for procedures on the major vessels of the neck that are not otherwise specified. It captures perioperative anesthesia care for vascular interventions involving carotid and other major cervical vessels, a high-acuity service with implications for resource use, perioperative risk management, and billing specificity across national payers. Major carriers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare.
Readers will find a concise overview of the clinical context for 00350, common diagnostic scenarios that map to neck vessel interventions, and the coding relationships that affect anesthesia reporting for these procedures. The publication summarizes payer coverage considerations, typical sites of service, and related anesthesia procedure codes to help delineate service scope. It also highlights where coding specificity matters for claim adjudication and when related codes may be used for simpler or more complex neck vessel anesthesia services. Data not available in the input are explicitly noted where applicable.
Billing Code Overview
CPT code 00350 describes anesthesia services provided for procedures on the major vessels of the neck, not otherwise specified. The service type is anesthesia for major vascular procedures of the neck, typically performed when surgical or endovascular interventions involve the carotid or other major cervical vessels. The typical site of service is an operating room or procedural suite where monitored anesthesia care or general anesthesia is delivered for vascular neck procedures.
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with hypertension, hyperlipidemia, and recent transient ischemic attack is scheduled for carotid endarterectomy for high-grade right internal carotid artery stenosis. The surgical team plans an operative exposure of the major vessels of the neck under general endotracheal anesthesia. Preoperative evaluation by the anesthesia team includes airway assessment, review of antiplatelet therapy, optimization of blood pressure, and discussion of neurologic monitoring (awake testing not planned; intraoperative cerebral oximetry and shunt readiness available). On the day of surgery the anesthesiologist directs induction, endotracheal intubation, invasive arterial monitoring, and maintenance of anesthesia, provides hemodynamic management during carotid clamping/unclamping, and participates in immediate postoperative handoff to the post-anesthesia care unit or intensive care unit as indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia management required substantially greater effort or complexity than typical for procedures on major neck vessels. |
23 | Unusual anesthesia |
