Official Description

Laminectomy with exploration and/or decompression of spinal cord and/or cauda equina, without facetectomy, foraminotomy or discectomy (eg, spinal stenosis), 1 or 2 vertebral segments; thoracic

Common Language Description

Laminectomy, also known as lamina excision, is a surgical procedure aimed at alleviating back pain and addressing issues related to the spinal cord, spinal nerve roots, and/or cauda equina. This procedure involves the removal of the lamina, which is the bony structure that forms the posterior part of the vertebral arch. By excising the lamina, the surgeon can relieve pressure on the spinal structures, which may be caused by conditions such as spinal stenosis. The procedure typically begins with a posterior skin incision made over the affected area of the spine, allowing access to the underlying structures. Once the incision is made, the overlying fat and muscle are carefully retracted to expose the lamina. The lamina is then excised, along with the paired ligaments known as the ligamentum flavum that connect adjacent vertebrae. This excision provides access to the spinal canal, where the surgeon can explore the area for any abnormalities. During the procedure, any adhesions between the dura mater and the ligamentum flavum are lysed, and the spinal nerve roots and/or cauda equina are meticulously dissected and freed within the intervertebral foramen. The laminectomy can be performed on one or two contiguous vertebral segments, depending on the patient's specific condition. If necessary, a separate arthrodesis may be performed to stabilize the spine following the laminectomy. It is important to note that laminectomy procedures are categorized based on the location of the vertebrae involved, with specific codes assigned for cervical, thoracic, lumbar, and sacral spine laminectomies.

1. Indications

The laminectomy procedure is indicated for various conditions that necessitate the exploration and/or decompression of the spinal cord and/or cauda equina. The following are explicitly provided indications for performing a laminectomy:

  • Spinal Stenosis - A condition characterized by the narrowing of the spinal canal, which can lead to pressure on the spinal cord and nerve roots, causing pain and neurological symptoms.
  • Back Pain - Persistent or severe back pain that may be attributed to compression of spinal structures, necessitating surgical intervention for relief.
  • Neurological Symptoms - Symptoms such as weakness, numbness, or tingling in the extremities that may result from nerve root compression.

2. Procedure

The laminectomy procedure involves several critical steps to ensure effective decompression of the spinal structures. The following procedural steps are outlined:

  • Step 1: Incision - A posterior skin incision is made over the affected segment of the spine to provide access to the underlying vertebrae. This incision is carefully planned to minimize damage to surrounding tissues.
  • Step 2: Retraction - The overlying fat and muscle tissues are retracted away from the lamina to expose the bony structure. This retraction is essential for clear visibility and access to the surgical site.
  • Step 3: Lamina Excision - The lamina is excised, which involves the removal of the bony arch of the vertebra. This step is crucial for relieving pressure on the spinal cord and nerve roots.
  • Step 4: Ligament Removal - The paired ligaments, known as the ligamentum flavum, that connect adjacent vertebrae are also excised. This removal further facilitates access to the spinal canal.
  • Step 5: Exploration of the Spinal Canal - The spinal canal is thoroughly explored to identify any abnormalities or adhesions. This exploration allows the surgeon to assess the condition of the spinal cord and nerve roots.
  • Step 6: Lysis of Adhesions - Any adhesions between the dura mater and the ligamentum flavum are lysed to free the spinal structures. This step is vital for restoring normal function and alleviating symptoms.
  • Step 7: Dissection of Nerve Roots - The spinal nerve roots and/or cauda equina are carefully dissected and freed within the intervertebral foramen, ensuring that they are no longer compressed.
  • Step 8: Stabilization (if necessary) - If indicated, a separate arthrodesis may be performed to stabilize the spine following the laminectomy, particularly if there is a risk of instability after the removal of the lamina.

3. Post-Procedure

After the laminectomy procedure, patients typically require monitoring for any immediate complications. Post-operative care may include pain management, physical therapy, and instructions for activity restrictions to promote healing. Patients are often advised to avoid heavy lifting and twisting motions during the initial recovery period. Follow-up appointments are essential to assess the surgical site, monitor recovery progress, and determine if additional interventions, such as arthrodesis, are necessary for spinal stabilization. The expected recovery time can vary based on the extent of the surgery and the individual patient's health status.

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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
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).
