Official Description

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

Common Language Description

Laminectomy, specifically referred to in CPT® Code 63017, is a surgical procedure that involves the excision of the lamina, which is the bony structure forming the posterior aspect of the vertebral arch. This procedure is primarily performed to investigate the underlying causes of back pain and to alleviate pressure on critical structures such as the spinal cord, spinal nerve roots, and the cauda equina. The cauda equina is a bundle of spinal nerves located at the lower end of the spinal cord, and its compression can lead to significant neurological deficits. During the procedure, a posterior skin incision is made over the affected area of the spine, allowing access to the lamina. The surrounding fat and muscle tissues are carefully retracted to expose the lamina, which is then excised. Additionally, the paired ligaments known as the ligamentum flavum, which connect adjacent vertebrae, are also removed to fully access the spinal canal. This exposure allows for exploration of the spinal canal and the identification of any adhesions that may be present between the dura mater and the ligamentum flavum. The surgical team meticulously dissects and frees the spinal nerve roots and/or cauda equina within the intervertebral foramen, ensuring that any impingement is resolved. It is important to note that this specific laminectomy procedure is performed on more than two contiguous vertebrae in the lumbar region. If stabilization of the spine is required, a separate arthrodesis procedure may be reported in conjunction with this laminectomy. For laminectomies involving more than two vertebral segments in the cervical and thoracic regions, different CPT codes (63015 and 63016, respectively) are utilized.

1. Indications

The laminectomy procedure described by CPT® Code 63017 is indicated for various conditions that necessitate the exploration and decompression of the spinal cord and/or cauda equina. The following are the explicitly provided indications for this procedure:

  • Spinal Stenosis - A narrowing of the spinal canal that can lead to pressure on the spinal cord and nerve roots, causing pain, numbness, or weakness.
  • Back Pain - Persistent or severe back pain that may be attributed to nerve compression or other spinal issues.
  • Neurological Symptoms - Symptoms such as weakness, numbness, or tingling in the legs or lower body that may indicate nerve root involvement.

2. Procedure

The laminectomy procedure involves several critical steps, each aimed at effectively relieving pressure on the spinal structures. The following procedural steps are outlined:

  • Step 1: Incision - A posterior skin incision is made over the affected segment of the lumbar spine. This incision allows access to the underlying structures that require intervention.
  • Step 2: Retraction - The overlying fat and muscle tissues are carefully retracted to expose the lamina. This step is crucial for providing a clear view of the surgical field and ensuring that the lamina can be accessed without damaging surrounding tissues.
  • Step 3: Excision of the Lamina - The lamina is excised to relieve pressure on the spinal cord and nerve roots. This excision is performed with precision to minimize trauma to adjacent structures.
  • Step 4: Removal of Ligamentum Flavum - The paired ligaments, known as the ligamentum flavum, which connect the lamina of adjacent vertebrae, are also excised. This step further opens the spinal canal and allows for better access to the underlying neural structures.
  • Step 5: Exploration of the Spinal Canal - The spinal canal is thoroughly explored to identify any adhesions or abnormalities. This exploration is essential for diagnosing the cause of the patient's symptoms.
  • Step 6: Lysis of Adhesions - Any adhesions between the dura mater and the ligamentum flavum are lysed to free the spinal cord and nerve roots, facilitating better mobility and function.
  • 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 any compression is alleviated.

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. Recovery time can vary based on the extent of the surgery and the patient's overall health. Patients are often advised to avoid heavy lifting and strenuous activities during the initial recovery phase. Follow-up appointments are essential to assess the surgical site, monitor for any signs of infection, and evaluate the effectiveness of the procedure in alleviating symptoms. If additional stabilization of the spine is necessary, separate arthrodesis may be performed, which will also be considered in the post-operative care plan.

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.
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).
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).
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
GC This service has been performed in part by a resident under the direction of a teaching physician
LT Left side (used to identify procedures performed on the left side of the body)
PD Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
