CPT 00626: Anesthesia for Thoracic Spine Surgery, Anterior Transthoracic
CPT code 00626 represents anesthesia services for thoracic spine and spinal cord procedures performed through an anterior transthoracic approach that require one-lung ventilation. This code captures a specialized anesthesia encounter for complex thoracic spinal surgery where lung isolation and advanced airway and ventilation management are necessary. Nationally, accurate use of 00626 matters for clinical documentation, perioperative risk stratification, and appropriate billing for high-acuity anesthetic care.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, common associated procedure types, and the typical site of service. The publication also summarizes payer coverage considerations and common modifiers and taxonomies associated with this service for operational clarity.
The content provides actionable reference material for coding teams, anesthesia departments, and billing professionals: it clarifies when 00626 applies, outlines related spinal surgical procedures that commonly coincide with its use, and indicates diagnostic contexts where thoracic spine anesthesia may be required. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 00626 describes anesthesia services provided for a patient undergoing a procedure on the thoracic spine and cord performed via an anterior transthoracic approach with one-lung ventilation.
Service type: Anesthesia for thoracic spine surgery, anterior transthoracic approach, one-lung ventilation
Typical site of service: Operating room / inpatient surgical suite (thoracic spinal surgery via transthoracic approach)
Clinical & Coding Specifications
Clinical Context
A 58-year-old male with progressive thoracic myelopathy secondary to multilevel thoracic disc herniation and spinal stenosis is scheduled for an anterior transthoracic thoracic discectomy and fusion. The patient reports increasing gait instability, bilateral lower-extremity numbness, and worsening midline thoracic pain refractory to conservative care. Preoperative evaluation identifies a history of well-controlled hypertension and prior tobacco use; ASA physical status classification is P3.
Perioperative workflow: The patient is brought to an operating room equipped for thoracic surgery with single-lung ventilation capability. After standard monitors and invasive arterial line placement, the anesthesia team induces general anesthesia and performs endotracheal intubation with a left-sided double-lumen tube to facilitate one-lung ventilation. Epidural or multimodal analgesia may be planned postoperatively. The anesthesiologist codes the procedure as 00626 for anesthesia for anterior transthoracic procedure on the thoracic spine/cord using one-lung ventilation. Postoperative care includes monitoring in a post-anesthesia care unit with potential transfer to a step-down or intensive care setting depending on intraoperative blood loss and respiratory status.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia required substantially greater clinical effort due to prolonged or technically difficult airway or intraoperative complications that increase anesthetic complexity. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary but the surgical or diagnostic procedure would ordinarily be performed without general anesthesia. |
50 | Bilateral procedure | Not commonly applicable to single-lung transthoracic spine surgery; used if simultaneous bilateral surgical procedures are performed. |
52 | Reduced services | Use when the planned regional or anesthetic portion is partially reduced or not completed for clinical reasons. |
53 | Discontinued procedure | Use when anesthesia services are terminated due to patient or surgical circumstances prior to completion. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during the procedure, impacting anesthesia planning. |
78 | Unplanned return to OR by the same physician following initial procedure | Use when patient requires an immediate return to the operating room for a related procedure during the same admission. |
AA | Anesthesia services performed personally by anesthesiologist | Use when the anesthesiologist personally performs the anesthesia services. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | Use when a physician supervises more than four CRNAs or anesthetists concurrently. |
AS | Monitored anesthesia care (MAC) by anesthesiologist | Use when MAC is provided by the anesthesiologist; rarely used for 00626 which describes general anesthesia for thoracic spine with one-lung ventilation but applicable if MAC is used for portions of care. |
QK | Medical direction of two, three, or four CRNAs/Anesthetists | Use when the physician medically directs multiple qualified anesthesia providers for this procedure. |
QS | Monitored anesthesia care service | Use when CMS-reportable MAC services are furnished and need separate reporting. |
QX | CRNA service with medical direction by physician | Use when a CRNA performs the anesthesia under physician direction. |
QY | Medical direction of one CRNA by a physician | Use when physician directs a single CRNA. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology Physician | Physician providing anesthesia services for complex thoracic spine procedures and airway/ventilation management. |
367500000X | Certified Registered Nurse Anesthetist | CRNA who may provide anesthesia care, including one-lung ventilation management, under supervision or direction. |
207LP2900X | Pain Medicine Physician | May be involved in perioperative pain management planning, regional techniques, or postoperative pain follow-up. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
M48.06 | Spinal stenosis, lumbar region | Lumbar spinal stenosis can present with neurologic symptoms; related degenerative spine pathology may influence surgical planning though 00626 specifically addresses thoracic anterior transthoracic procedures. |
M51.06 | Intervertebral disc disorders with myelopathy, lumbar region | Disc herniation with myelopathy indicates cord compression; similar pathophysiology in thoracic discs may necessitate anterior transthoracic decompression. |
G95.9 | Disease of spinal cord, unspecified | Reflects intrinsic spinal cord disease or unspecified cord dysfunction relevant when thoracic surgery aims to decompress or biopsy cord lesions. |
M54.5 | Low back pain | Symptom-level diagnosis; may coexist with thoracic pathology and be part of overall spine disease burden considered perioperatively. |
M47.816 | Spondylosis without myelopathy or radiculopathy, lumbar region | Degenerative changes of the spine that can be associated with multilevel disease; surgical approaches may vary but influence anesthetic planning. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
63030 | Laminectomy with decompression of spinal cord and/or nerve roots | May be performed in thoracic decompression procedures; anesthesia 00626 supports intrathoracic access and spinal cord decompression. |
63047 | Laminectomy, facetectomy and foraminotomy | Represents posterior decompression techniques that may be staged or combined with anterior approaches; anesthesia planning depends on combined procedures. |
22830 | Exploration of spinal fusion | Performed when assessing or revising prior fusion hardware during thoracic spine surgery; impacts anesthetic time and complexity. |
20930 | Spinal bone graft, local | Bone grafting often accompanies fusion procedures performed through an anterior transthoracic approach; increases operative time and anesthetic considerations. |
22558 | Arthrodesis, anterior interbody technique, lumbar | Describes anterior interbody fusion technique (lumbar); included here as a related anterior approach arthrodesis code, analogous in workflow to anterior thoracic interbody fusion procedures where 00626 would apply. |
