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; sacral

Common Language Description

Laminectomy, also known as lamina excision, is a surgical procedure aimed at alleviating back pain and relieving pressure on the spinal cord, spinal nerve roots, and/or cauda equina. The lamina refers to the bony structure that forms the posterior aspect of the vertebral arch, which is crucial for protecting the spinal cord. During the procedure, a posterior skin incision is made over the affected area of the spine to access the lamina. The surgeon retracts the overlying fat and muscle to expose the lamina, which is then excised. This excision also involves the removal of the paired ligaments, known as the ligamentum flavum, that connect the laminae of adjacent vertebrae. By doing so, the spinal canal is opened up, allowing for exploration and identification of any underlying issues. The procedure may also involve lysis of adhesions between the dura mater and the ligamentum flavum, facilitating the careful dissection and freeing of the spinal nerve roots and/or cauda equina within the intervertebral foramen. Laminectomy can be performed on one or two contiguous vertebral segments, and if necessary, a separate arthrodesis may be conducted to stabilize the spine. This specific code, CPT® 63011, is designated for laminectomy procedures performed on the sacral spine.

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 this procedure:

  • 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 nerve compression or other spinal issues that require surgical intervention for relief.
  • Neurological Symptoms - Symptoms such as weakness, numbness, or tingling in the lower extremities that may result from spinal cord or 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 lamina. This incision is carefully placed to minimize damage to surrounding tissues.
  • Step 2: Retraction - The overlying fat and muscle are retracted away from the lamina to expose the bony structure. This step is crucial for providing a clear view of the surgical field and ensuring that the lamina can be adequately accessed.
  • Step 3: Excision of the Lamina - The lamina is excised, which involves removing the bony arch of the vertebra. This excision is essential for relieving pressure on the spinal cord and nerve roots.
  • Step 4: Removal of Ligamentum Flavum - The paired ligaments, known as the ligamentum flavum, that connect the laminae of adjacent vertebrae are also excised. This step further opens the spinal canal and allows for better access to the underlying structures.
  • Step 5: Exploration of the Spinal Canal - The spinal canal is thoroughly explored to identify any adhesions or abnormalities. This exploration may involve lysis of adhesions between the dura mater and the ligamentum flavum, which can contribute to nerve compression.
  • Step 6: Dissection of Nerve Roots - The spinal nerve roots and/or cauda equina are carefully dissected and freed within the intervertebral foramen. This step is critical for alleviating any compression that may be causing neurological symptoms.
  • Step 7: Stabilization (if necessary) - If indicated, a separate arthrodesis may be performed to stabilize the spine following the laminectomy. This step is not part of the laminectomy itself but may be necessary depending on the patient's condition.

3. Post-Procedure

Post-procedure care following a laminectomy involves monitoring the patient for any complications and managing pain effectively. Patients are typically advised to follow specific recovery protocols, which may include physical therapy to strengthen the back and improve mobility. The expected recovery time can vary based on the extent of the surgery and the individual patient's health status. It is essential for patients to adhere to follow-up appointments to ensure proper healing and to address any concerns that may arise during the recovery process.

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).
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.
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.
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.
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).
CC Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed)
