CPT 00625: Anesthesia for Thoracic Spine Procedure, Anterior Transthoracic
Headline: CPT code 00625: Anesthesia for Anterior Transthoracic Thoracic Spine Procedures
Lead: CPT code 00625 identifies anesthesia services for surgeries on the thoracic spine and spinal cord performed through an anterior transthoracic approach without use of one‑lung ventilation. The code specifies a particular surgical access and anesthetic context that affects perioperative planning and billing.
CPT code 00625 represents anesthesia care for complex thoracic spine and spinal cord procedures using an anterior transthoracic approach, where one‑lung ventilation is not employed. Nationally, precise CPT assignment for specialized spine approaches matters for appropriate payment, clinical communication, and resource planning for high-acuity surgical cases.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical scope and typical site of service, an overview of payer coverage considerations, and pointers to closely related CPT anatomy (notably the version of the code that includes one‑lung ventilation). The publication outlines common billing elements and contextual clinical notes relevant to anesthesiology, pain management, and critical care clinicians who support thoracic spine surgery.
What readers will learn: the clinical scenario captured by 00625, where it is typically billed, the main national payers referenced in the analysis, and links to related coding for thoracic spine anesthesia to assist billing accuracy and program alignment.

Billing Code Overview
CPT code 00625 describes anesthesia services provided for a patient undergoing a procedure on the thoracic spine and spinal cord performed via an anterior transthoracic approach, without the use of one‑lung ventilation.
Service type: Anesthesia for thoracic spine and spinal cord surgery (anterior transthoracic approach)
Typical site of service: Operating room / inpatient surgical suite involving thoracic surgical access
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with progressive thoracic myelopathy presents for anterior transthoracic decompression and fusion of the thoracic spine for symptomatic spinal cord compression. He reports gait instability, lower extremity numbness, and chronic mid-back pain refractory to conservative care. Preoperative assessment by the anesthesiology team documents coronary artery disease, well-controlled hypertension, and an American Society of Anesthesiologists (ASA) physical status of P3. The planned operative approach is an anterior transthoracic thoracic corpectomy and interbody fusion without use of one‑lung ventilation. The anesthesia workflow includes preoperative airway evaluation, invasive arterial monitoring placement, induction with endotracheal intubation, maintenance of general anesthesia with hemodynamic goal-directed therapy, intraoperative neurophysiologic monitoring coordination, and postoperative handoff to the intensive care unit for neurological observation and pain control. Intraoperative events that may alter coding or documentation include unexpected prolonged operative time, significant blood loss requiring transfusion, conversion to thoracotomy with prolonged ventilatory support, or the need for regional adjuncts for pain management.
Coding Specifications
-
Modifier
22is used for a substantially greater-than-normal service due to increased complexity. -
Modifier
23is used when the procedure is performed under general anesthesia but is an unusual circumstance where the procedure itself is normally done without anesthesia. -
Modifier
50is used when bilateral procedures are performed (rare for this anterior thoracic approach). -
Modifier
52is used when a service is partially reduced or not completed as planned. -
Modifier
53is used when the procedure is discontinued because of extenuating circumstances or those that threaten the patient. -
Modifier
54is used to indicate the surgeon's postoperative management only (not typically applied to anesthesia claims). -
Modifier
56is used to report the preoperative care only (rare on anesthesia claims). -
Modifier
62is used to report co-surgeons when two surgeons of different specialties operate together. -
Modifier
78is used for an unplanned return to the operating room for a related procedure during the global period. -
Modifier
AAis used to indicate the services were performed personally by the anesthesiologist. -
Modifier
ASis used when the service is performed by the anesthesiologist as part of the surgical team in a teaching hospital. -
Modifier
QKis used to indicate medical direction of two, three, or four concurrent anesthesia procedures. -
Modifier
QXis used when certified registered nurse anesthetist (CRNA) service is provided under physician supervision. -
Modifier
QSis used to report monitored anesthesia care (MAC) services when appropriate.
| Modifier | Description | When to Use |
|---|---|---|
AA | Anesthesia services performed personally by an anesthesiologist | Use when the anesthesiologist personally performs all anesthesia services for 00625 |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Use when the physician medically directs multiple concurrent anesthesia procedures including this case |
QX | CRNA service with physician supervision | Use when a CRNA furnishes the anesthesia and a physician is medically directing |
QS | Monitored anesthesia care (MAC) | Use when MAC is documented and appropriate for the procedure (rare for this code) |
22 | Increased procedural service | Use when anesthesia care is substantially more complex or prolonged due to patient or surgical factors |
52 | Reduced services | Use when the anesthetic was partially reduced vs. planned (e.g., abbreviated procedure) |
53 | Discontinued procedure | Use when anesthesia is discontinued because the surgery was aborted for patient safety |
78 | Unplanned return to OR | Use when the patient returns to the OR emergently for a related procedure during the global period |
62 | Two surgeons | Use when co-surgeons of different specialties perform the operation, affecting anesthesia coordination |
AA | (See above) | (Duplicate entry retained to reflect claim-level use) |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary specialty providing perioperative anesthesia care for thoracic spine procedures |
207LA0401X | Pain Medicine (Anesthesiology) | May provide perioperative or postoperative pain management and regional techniques |
207LC0200X | Critical Care Medicine (Anesthesiology) | Provides postoperative critical care management for complex neurosurgical patients |
Related Diagnoses
