Common Language Description

Laminotomy, specifically a hemilaminectomy, is a surgical procedure performed to relieve pressure on nerve roots in the cervical spine. This procedure is indicated for patients who have previously undergone surgery in the cervical region and require re-exploration due to persistent symptoms or complications. The term "laminotomy" refers to the surgical removal of a portion of the lamina, which is the bony arch of the vertebra that covers the spinal canal. In this context, a hemilaminectomy involves the removal of one side of the lamina to access the spinal canal and the nerve roots. The procedure may also include additional techniques such as partial facetectomy, which involves the removal of a portion of the facet joint, and foraminotomy, which is the enlargement of the foramen to relieve nerve root compression. Furthermore, if a herniated intervertebral disc is present, the surgeon may excise the herniated disc material to decompress the affected nerve root. The goal of this procedure is to alleviate pain, restore function, and improve the quality of life for patients suffering from nerve root compression in the cervical spine.

1. Indications

The laminotomy (hemilaminectomy) procedure is indicated for the following conditions:

  • Re-exploration of cervical disc space - This procedure is performed when a patient has previously undergone cervical spine surgery and requires further intervention due to unresolved symptoms or complications.
  • Decompression of nerve root(s) - Indicated for patients experiencing nerve root compression, which may manifest as pain, weakness, or numbness in the upper extremities.
  • Herniated intervertebral disc - The procedure is indicated when a herniated disc is identified as the source of nerve root compression, necessitating excision of the herniated material.

2. Procedure

The laminotomy (hemilaminectomy) procedure involves several key steps to ensure effective decompression of the nerve roots:

  • Step 1: Reopening the incision - The surgeon begins by reopening the previous skin incision made during the initial surgery to access the cervical spine. This allows for direct access to the previously explored disc space.
  • Step 2: Exposure of the disc space - Once the incision is reopened, the surgeon carefully exposes the disc space. This may involve the removal of scar tissue that has formed over the laminae since the last procedure.
  • Step 3: Enlarging the laminotomy - The existing laminotomy is enlarged to provide better access to the spinal canal and the nerve roots. This step is crucial for effective decompression.
  • Step 4: Dissection of scar tissue - The surgeon meticulously dissects any scar tissue present within the disc space, which may be contributing to nerve root compression.
  • Step 5: Identification and exploration of the nerve root - The nerve root is identified and explored to assess the extent of compression and to determine the necessary interventions.
  • Step 6: Removal of scar tissue and bony spurs - Any scar tissue or bony spurs that are compressing the nerve root are removed to alleviate pressure and restore normal function.
  • Step 7: Facetectomy (if necessary) - If indicated, a portion of the flat articular surface (facet) of the vertebra may be excised to further relieve nerve root compression.
  • Step 8: Foraminotomy (if necessary) - The foramen, the opening through which the nerve root exits the spinal canal, may be enlarged as needed to ensure adequate decompression.
  • Step 9: Excision of herniated disc material - If a herniated disc is found during the procedure, the surgeon will curette the disc material from the disc space to decompress the affected nerve root.
  • Step 10: Wound closure - Upon completion of the procedure, the surgeon controls any bleeding through coagulation, irrigates the wound, and then closes the incisions to promote healing.

3. Post-Procedure

After the laminotomy (hemilaminectomy) procedure, patients can expect a recovery period that may involve monitoring for any complications, managing pain, and following specific post-operative care instructions. It is essential for patients to adhere to their surgeon's recommendations regarding activity restrictions, physical therapy, and follow-up appointments to ensure optimal recovery and to assess the success of the procedure. The expected recovery time may vary based on individual circumstances, including the extent of the surgery and the patient's overall health.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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)
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
GC This service has been performed in part by a resident under the direction of a teaching physician
