Official Description

Laminectomy for excision or occlusion of arteriovenous malformation of spinal cord; thoracic

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Laminectomy for excision or occlusion of an arteriovenous malformation (AVM) of the spinal cord, specifically coded as CPT® 63251, is a surgical procedure aimed at addressing a rare congenital anomaly characterized by an abnormal tangle of arteries and veins located on, in, or near the spinal cord. This condition can lead to significant complications, including the potential for oxygenated blood to be inadequately supplied to the spinal cord tissues, which may result in tissue necrosis. Additionally, the presence of an AVM can cause the rupture of weakened blood vessels or lead to compression of the spinal cord itself, both of which can have serious neurological consequences. During the procedure, an incision is made over the thoracic region where the AVM is situated, extending down to the spinous processes. The surgical team retracts the muscle away from the lamina and facet joint to gain access. A bone drill is then utilized to remove part or all of the lamina, allowing for exposure of the spinal cord. Once the AVM is located, the blood vessels supplying it are identified and ligated with sutures. The AVM can then be excised or occluded permanently using sutures or clamps, effectively addressing the vascular anomaly and mitigating the associated risks.

1. Indications

The procedure coded as CPT® 63251 is indicated for the treatment of arteriovenous malformations (AVMs) located in the thoracic region of the spinal cord. The following conditions may warrant this surgical intervention:

  • Spinal Cord AVM A congenital anomaly characterized by abnormally tangled arteries and veins that can disrupt normal blood flow to spinal cord tissues.
  • Neurological Symptoms Symptoms such as pain, weakness, or sensory deficits that may arise due to the compression of the spinal cord or surrounding structures caused by the AVM.
  • Risk of Rupture The potential for rupture of the AVM, which can lead to hemorrhage and significant neurological damage.
  • Progressive Symptoms Worsening neurological deficits or other complications that may arise from the presence of the AVM, necessitating surgical intervention.

2. Procedure

The procedure for CPT® 63251 involves several critical steps to ensure the successful excision or occlusion of the thoracic spinal cord AVM. The following procedural steps are undertaken:

  • Step 1: Incision The surgical process begins with an incision made over the thoracic region where the AVM is located. This incision is carefully extended down to the spinous processes to provide adequate access to the underlying structures.
  • Step 2: Muscle Retraction Once the incision is made, the muscle tissue is retracted away from the lamina and facet joint. This retraction is essential to expose the bony structures of the spine and facilitate the next steps of the procedure.
  • Step 3: Laminectomy A bone drill is employed to remove part or all of the lamina, which is the bony arch of the vertebra. This step is crucial as it allows for direct exposure of the spinal cord and the AVM itself.
  • Step 4: Identification of AVM With the spinal cord now exposed, the surgeon locates the AVM. This involves careful examination of the vascular structures to identify the abnormal tangle of blood vessels.
  • Step 5: Ligation of Blood Vessels The blood vessels supplying the AVM are identified and ligated using sutures. This step is critical to prevent excessive bleeding during the excision or occlusion of the AVM.
  • Step 6: Excision or Occlusion Finally, the AVM is either excised or permanently occluded using sutures or clamps. This definitive step aims to eliminate the abnormal blood flow associated with the AVM, thereby reducing the risk of complications.

3. Post-Procedure

After the completion of the procedure, patients typically require careful monitoring for any signs of complications, such as bleeding or neurological deficits. Post-operative care may include pain management, physical therapy, and follow-up imaging studies to assess the success of the intervention. Recovery time can vary based on the extent of the surgery and the patient's overall health, but close observation is essential to ensure proper healing and to address any potential issues that may arise following the procedure.

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).
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.
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).
