Official Description

Laminectomy, facetectomy and foraminotomy (unilateral or bilateral with decompression of spinal cord, cauda equina and/or nerve root[s], [eg, spinal or lateral recess stenosis]), single vertebral segment; thoracic

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. This procedure is particularly relevant in cases where there is spinal or lateral recess stenosis, which can lead to significant discomfort and neurological symptoms. The lamina is a bony structure that forms the posterior aspect of the vertebral arch, and its removal is essential for accessing the underlying structures of the spine. During the procedure, a posterior skin incision is made over the affected area of the spine, allowing the surgeon to retract the overlying fat and muscle to expose the lamina. The excision of the lamina, along with the paired ligaments known as the ligamentum flavum, facilitates a thorough inspection of the spinal anatomy, including the superior and inferior articular facets and the pars interarticularis. This access enables the surgeon to explore the openings under the facet joints where spinal nerves emerge, and to remove any bone that may be compressing the nerve roots. The procedure also involves enlarging the intervertebral foramen to decompress the spinal cord, lysing any adhesions between the dura mater and the ligamentum flavum, and carefully dissecting the spinal nerve roots and/or cauda equina to free them within the intervertebral foramen. The surgical wound is then closed in layers, ensuring proper healing. This specific code, CPT® 63046, is designated for laminectomy, facetectomy, and foraminotomy performed at a single vertebral segment in the thoracic region.

1. Indications

The procedure is indicated for patients experiencing symptoms related to spinal or lateral recess stenosis, which may include:

  • Back Pain Persistent pain in the back that may radiate to other areas.
  • Nerve Root Compression Symptoms such as numbness, tingling, or weakness in the extremities due to pressure on spinal nerves.
  • Cauda Equina Syndrome A serious condition characterized by severe back pain, loss of bladder or bowel control, and weakness in the legs.
  • Spinal Cord Compression Symptoms including difficulty walking, balance issues, or other neurological deficits resulting from pressure on the spinal cord.

2. Procedure

The laminectomy, facetectomy, and foraminotomy procedure involves several critical steps to ensure effective decompression of the spinal structures:

  • Step 1: Incision A posterior skin incision is made over the affected segment of the thoracic spine, allowing access to the underlying structures.
  • Step 2: Retraction The overlying fat and muscle are carefully retracted to expose the lamina, which is the bony structure that will be excised.
  • Step 3: Lamina Excision The lamina is excised to relieve pressure on the spinal cord and nerve roots. This step is crucial for accessing the spinal canal.
  • Step 4: Ligament Removal The paired ligaments, known as the ligamentum flavum, that connect adjacent laminae are also excised to facilitate further exploration.
  • Step 5: Inspection of Facets The superior and inferior articular facets and the pars interarticularis are inspected for any abnormalities or additional sources of compression.
  • Step 6: Nerve Root Exploration The openings under the facet joints, where the spinal nerves emerge, are explored, and any bone compressing the nerve roots is removed as necessary.
  • Step 7: Spinal Canal Exposure The spinal canal is fully exposed and explored to assess the condition of the spinal cord and surrounding structures.
  • Step 8: Foramen Enlargement The intervertebral foramen is enlarged to decompress the spinal cord and nerve roots, alleviating pressure and improving function.
  • Step 9: Adhesion Lysis Any adhesions between the dura mater and the ligamentum flavum are lysed to free the spinal structures.
  • Step 10: Dissection of Nerve Roots The spinal nerve roots and/or cauda equina are carefully dissected and freed within the intervertebral foramen to ensure they are not compressed.
  • Step 11: Wound Closure The surgical wound is closed in layers, ensuring proper healing and minimizing the risk of infection.

3. Post-Procedure

After the laminectomy, facetectomy, and foraminotomy procedure, patients can expect a recovery period that may involve pain management and physical therapy. Monitoring for any signs of complications, such as infection or neurological deficits, is essential. Patients are typically advised to follow specific post-operative care instructions, which may include restrictions on physical activity and guidelines for wound care. The expected recovery time can vary based on individual health factors and the extent of the surgery performed.

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
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.
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).
GC This service has been performed in part by a resident under the direction of a teaching physician
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
