CPT 00563: Anesthesia for Cardiac Surgery with Bypass and Circulatory Arrest
Headline: CPT code 00563 defines high-acuity anesthesia for cardiac procedures with cardiopulmonary bypass and hypothermic circulatory arrest
Lead: CPT code 00563 covers anesthesia services for major open-heart surgeries involving the heart, pericardium, and great vessels where a pump oxygenator takes over cardiac and pulmonary function and hypothermic circulatory arrest is used. This designation reflects one of the most resource-intensive anesthesia services and carries implications for clinical preparation, intraoperative monitoring, and payer policy.
What the code represents and why it matters: CPT code 00563 identifies anesthesia care for operations that require cardiopulmonary bypass and deliberate cooling with temporary cessation of circulation. Nationally, this code signals high procedural complexity, extended anesthesia time, advanced monitoring and staffing needs, and significant perioperative risk—factors that affect hospital resource utilization and payer coverage discussions.
Key payers covered: Analysis includes major national commercial payers and public coverage models: Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare.
What readers will learn: The publication provides clinical context for use of CPT code 00563, comparisons to related cardiac anesthesia codes, common billing modifiers and practice taxonomies (listed separately), and guidance on typical sites of service. Benchmark and policy summaries summarize how payers commonly classify and adjudicate this high-acuity anesthesia service and highlight documentation elements that support correct code assignment.
Scope: This is a national overview intended for clinicians, coding professionals, and reimbursement analysts seeking concise information on code definition, clinical context, and payer coverage landscape.

Billing Code Overview
CPT code 00563 describes anesthesia services for procedures on the heart, pericardium, and great vessels that require cardiopulmonary bypass and hypothermic circulatory arrest. The service involves management of anesthesia for complex open cardiac surgery in which a pump oxygenator assumes heart and lung function and the patient is cooled to permit temporary cessation of circulation.
Service type: Cardiac anesthesia for open heart surgery with cardiopulmonary bypass and hypothermic circulatory arrest
Typical site of service: Inpatient hospital operating room (cardiac surgery suite), often within a tertiary care or academic medical center
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with severe calcific aortic stenosis (I35.0) and concomitant coronary atherosclerotic disease (I25.10) presents for an elective combined aortic valve replacement and coronary artery bypass grafting (CABG). Preoperative evaluation documents heart failure symptoms (I50.9) and an atrial septal defect (Q21.1) identified on intraoperative transesophageal echocardiography. The surgical plan requires median sternotomy, cardiopulmonary bypass with a pump-oxygenator, and periods of hypothermic circulatory arrest for safe reconstruction of the ascending aorta and repair of the atrial septal defect.
The anesthesia workflow includes: preoperative assessment and optimization, arterial and central venous access placement in the operating room, induction with endotracheal intubation, invasive monitoring (arterial line, pulmonary artery catheter as indicated), transesophageal echocardiography for intraoperative hemodynamic guidance, management of cardiopulmonary bypass initiation and separation, active temperature management including cooling for hypothermic circulatory arrest, coagulation and blood product management, and postoperative handoff to the cardiothoracic intensive care unit for continued ventilatory and hemodynamic support.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia care required substantially greater effort, time, or complexity beyond typical for cardiac procedures (document rationale). |
23 | Unusual anesthesia | Use when general anesthesia is administered but usually not required for the procedure performed (rare for this code; only if applicable). |
50 | Bilateral procedure | Use if truly bilateral surgical procedures are performed in same operative session when applicable (rare for cardiac surgery). |
52 | Reduced services | Use when the anesthetic service is partially reduced or not completed as expected. |
53 | Discontinued procedure | Use when anesthesia is discontinued due to extenuating circumstances prior to completion of planned procedure. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons for portions of the operation affecting anesthetic complexity. |
78 | Unplanned return to OR | Use for unplanned return to the operating room for a related procedure during the global period that alters anesthesia billing. |
AA | Anesthesia by anesthesiologist | Use to designate the service was personally performed by an anesthesiologist. |
AS | Physician assistant/NP/CRNA service with direction by physician | Use when a medically directed or supervised anesthesia service is provided under appropriate supervision rules. |
QK | Medical direction by CRNA with 2–4 concurrent anesthesia services | Use when a physician medically directs multiple CRNAs concurrently, meeting supervision elements. |
QX | CRNA service incident to a physician under Medicare | Use to indicate CRNA service without physician supervision where applicable under payer rules. |
QS | Monitored anesthesia care service | Use when service rendered is monitored anesthesia care rather than general anesthesia (rare for this code). |
AD | Medical supervision by physician; more than four concurrent anesthesia procedures | Use when physician supervises more than four concurrent anesthetics per payer policy. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary specialty providing perioperative anesthesia care for cardiac surgery. |
207LA0401X | Pediatric Anesthesiology | Applies when pediatric cardiac patients require specialized anesthetic management. |
207LC0200X | Critical Care Medicine (Anesthesiology) | Involvement for perioperative management of high-acuity cardiothoracic patients and postoperative ICU care. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I25.10 | Atherosclerotic heart disease of native coronary artery without angina pectoris | Coronary artery disease commonly necessitates CABG performed with cardiopulmonary bypass during complex cardiac surgery. |
I34.0 | Nonrheumatic mitral (valve) insufficiency | Mitral regurgitation may require valve repair or replacement during open-heart procedures using pump oxygenator. |
I35.0 | Nonrheumatic aortic (valve) stenosis | Primary indication for aortic valve replacement, frequently requiring cardiopulmonary bypass and hypothermic strategies for complex aortic work. |
I50.9 | Heart failure, unspecified | Heart failure increases perioperative risk and influences anesthetic management and postoperative ICU care. |
Q21.1 | Atrial septal defect | Congenital intracardiac shunt that may be repaired during the same operative session, often under cardiopulmonary bypass. |
