CPT 00352: Anesthesia for Major Vessels of Neck Procedures
CPT code 00352 denotes anesthesia services for procedures on the major vessels of the neck, including simple ligation. This code identifies perioperative anesthesia care specific to vascular surgery of the neck and is important for appropriate clinical reporting, resource allocation, and national claims processing for complex head-and-neck vascular procedures. Accurate coding supports quality measurement, case-mix assessment, and appropriate payment pathways for anesthesiology services tied to these high-acuity procedures.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. The publication provides a national perspective on coding context and payer coverage patterns rather than state-level policy. Readers will find a concise clinical description of the service, common ICD-10 diagnoses that align with major aortic and vascular pathology relevant to perioperative care, and the relationship of 00352 to related anesthesia codes for thoracic and cardiac vascular procedures. The report also outlines typical sites of service and service line placement for billing workflows.
This summary prepares clinical, coding, and revenue cycle stakeholders to identify when 00352 applies, understand its clinical setting, and see how it maps alongside related anesthesia codes used for complex cardiovascular and major-vessel operations.

Billing Code Overview
CPT code 00352 describes anesthesia services provided for procedures on the major vessels of the neck, including simple ligation. The service type is anesthesia for vascular surgery of the neck, and the typical site of service is an operating room or surgical suite where major vascular procedures on neck vessels are performed.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with hypertension and peripheral vascular disease presents with a painful, pulsatile neck mass and imaging demonstrating a symptomatic carotid artery aneurysm involving the common carotid and proximal internal carotid requiring surgical ligation of a major neck vessel. The anesthesiologist performs general endotracheal anesthesia with invasive monitoring (arterial line, central venous access as indicated) and prepares for possible massive hemorrhage and vascular control. The perioperative workflow includes preoperative airway assessment, review of anticoagulation and antiplatelet agents, induction with rapid-sequence or standard technique as clinically indicated, arterial pressure monitoring, vasopressor availability, transfusion readiness, and postoperative transfer to an intensive care unit for continued hemodynamic and neurologic monitoring. Documentation includes procedure performed on major vessels of neck, anesthetic technique, monitoring modalities, intraoperative events (blood loss, transfusion, hemodynamic instability), and post-anesthesia disposition.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural service | When anesthesia or associated services required substantially greater work due to complexity, prolonged time, or complications beyond typical for major neck vessel procedures. |
23 | Unusual anesthesia | For emergency anesthesia when general anesthesia is medically necessary but not normally used for the procedure. |
50 | Bilateral procedure | When identical procedures are performed on both left and right major neck vessels during the same operative session. |
52 | Reduced services | When the planned anesthetic service is partially reduced or not completed as originally intended. |
53 | Discontinued procedure | When the anesthesia service is discontinued due to patient deterioration or intraoperative cancellation after induction. |
62 | Two surgeons | When two surgeons perform distinct surgical services concurrently that affect anesthetic management for major neck vessel surgery. |
78 | Unplanned return to OR | For return to the operating room for a related procedure during the postoperative global period requiring additional anesthesia services. |
AA | Anesthesia by anesthesiologist | When an MD or DO anesthesiologist personally performs the anesthesia service. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | When the physician provides required medical direction or supervision beyond the typical ratio. |
QK | Medical direction of two, three, or four CRNAs | When the physician medically directs multiple CRNAs for concurrent anesthesia services. |
QS | Monitored anesthesia care service | If monitored anesthesia care is provided instead of general anesthesia for select neck vessel procedures (rare) |
QX | CRNA service: CRNA with medical direction by a physician | When a CRNA provides the anesthesia under physician medical direction. |
FY | Physician service for payment purposes (anesthesia) | When a non-physician anesthetist's services are billed under applicable rules and a physician is involved per payer policy. |
62 | Two surgeons | See above; relevant when dual-surgeon approach influences anesthesia management. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary specialty for the provider performing anesthesia services for major neck vessel procedures. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I71.01 | Dissection of thoracic aorta | Major vessel pathology that may require extensive vascular surgical and anesthetic management; included as a related large-vessel diagnosis. |
I71.2 | Thoracic aortic aneurysm, without rupture | Represents aneurysmal disease of the thoracic aorta; anesthetic care parallels other major vessel procedures with high hemodynamic risk. |
I71.3 | Abdominal aortic aneurysm, ruptured | Acute, high-risk vascular emergency illustrating scenarios where major vessel anesthesia and massive transfusion protocols are used. |
I71.4 | Abdominal aortic aneurysm, without rupture | Elective large-vessel repair scenario with perioperative monitoring and anesthetic planning similar to neck vessel major-vessel cases. |
I71.9 | Aortic aneurysm of unspecified site, without rupture | General aortic aneurysm diagnosis indicating large-vessel disease; relevant for anesthesia planning and risk stratification. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
00562 | Anesthesia for procedures on heart, pericardial sac, and great vessels of chest; with pump oxygenator | Applicable when surgery involves great vessels near the thoracic inlet or requires cardiopulmonary bypass techniques that extend anesthetic complexity. |
00566 | Anesthesia for direct coronary artery bypass grafting; with pump oxygenator | Related in complex vascular cases where crossover with cardiac bypass techniques or shared resources occurs; not typical for isolated neck vessel ligation. |
00567 | Anesthesia for direct coronary artery bypass grafting; without pump oxygenator | Relevant in multidisciplinary centers where cardiac and great vessel anesthetic protocols overlap. |
00570 | Anesthesia for repair of coarctation of aorta | Represents anesthesia services for major aortic repair; included as related great-vessel anesthesia codes when large-vessel techniques or monitoring are comparable. |
