Official Description

Vertebral corpectomy (vertebral body resection), partial or complete, for excision of intraspinal lesion, single segment; extradural, lumbar or sacral by transperitoneal or retroperitoneal approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Vertebral corpectomy, as defined by CPT® Code 63303, is a surgical procedure that involves the resection of a vertebral body, which may be either partial or complete, specifically for the purpose of excising an intraspinal lesion. This procedure is performed on a single segment of the lumbar or sacral spine and is characterized by the removal of the vertebral body along with the intervertebral discs located above and below the affected vertebra. The lesions targeted in this procedure are located within the spinal canal but are positioned outside the dura mater, classifying them as extradural lesions. The surgical approach can be either transperitoneal, which involves an incision in the abdomen and entry into the peritoneal cavity, or retroperitoneal, which requires a flank incision to access the spine from an anterolateral position. During the procedure, careful dissection is performed to expose the affected vertebral segment while protecting vital structures in the surrounding area. The use of a surgical microscope aids in the precise removal of the intervertebral discs and the vertebral body, allowing for the identification and exploration of the lesion or tumor. Once the lesion is excised, additional procedures such as bone grafting and spinal instrumentation may be performed to ensure stability and support for the spine. This comprehensive approach is essential for addressing the underlying pathology while maintaining the structural integrity of the spinal column.

1. Indications

The vertebral corpectomy procedure is indicated for the excision of intraspinal lesions that are located outside the dura mater. The specific indications for performing this procedure include:

  • Intraspinal Lesion The presence of a lesion or tumor within the spinal canal that requires surgical intervention for removal.
  • Extradural Location The lesion must be located outside the dura mater, allowing for access through the vertebral body.
  • Single Segment Involvement The procedure is indicated when the lesion affects only one segment of the lumbar or sacral spine.

2. Procedure

The vertebral corpectomy procedure involves several critical steps to ensure the successful excision of the lesion while maintaining spinal stability. The procedural steps are as follows:

  • Step 1: Surgical Approach The surgeon selects either a transperitoneal or retroperitoneal approach based on the location of the lesion. For the transperitoneal approach, an incision is made in the abdomen, allowing access to the peritoneal cavity, while the retroperitoneal approach involves a flank incision to access the spine from the side.
  • Step 2: Exposure of the Affected Segment Once the appropriate approach is established, surrounding tissues are carefully dissected to expose the affected lumbar or sacral segment. This step requires meticulous attention to protect vital structures in the vicinity.
  • Step 3: Removal of Intervertebral Discs The intervertebral discs located above and below the vertebral body are removed first. This is done with the assistance of a surgical microscope, which allows for precise dissection and removal of the discs from surrounding tissues.
  • Step 4: Excision of the Vertebral Body After the discs are removed, the vertebral body is excised. The surgeon identifies and explores the lesion or tumor within the spinal canal, confirming that it lies outside the dura mater.
  • Step 5: Lesion Dissection The lesion or tumor is carefully dissected free from surrounding tissues using the operating microscope, ensuring complete excision without damaging adjacent structures.
  • Step 6: Bone Grafting and Fusion Following the excision of the lesion, separately reportable bone grafting and fusion procedures may be performed. A bone graft is placed in the surgical defect to support the anterior aspect of the spine where the discs and vertebral body have been removed. The surrounding bone is contoured to facilitate the placement of the graft and promote fusion with adjacent bone.
  • Step 7: Stabilization Separately reportable spinal instrumentation may be utilized to stabilize the spine post-procedure, ensuring structural integrity during the healing process.
  • Step 8: Closure Upon completion of the procedure, the surgeon controls any bleeding and closes the soft tissues and skin in layers to promote optimal healing.

3. Post-Procedure

After the vertebral corpectomy, patients typically require monitoring for any complications related to the surgery. Post-procedure care may include pain management, physical therapy, and follow-up imaging studies to assess the surgical site and ensure proper healing. Patients are advised on activity restrictions to prevent strain on the surgical area, and they may need to follow specific rehabilitation protocols to regain strength and mobility. The recovery process can vary based on individual patient factors and the extent of the procedure performed.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
