Official Description

Transpedicular approach with decompression of spinal cord, equina and/or nerve root(s) (eg, herniated intervertebral disc), single segment; each additional segment, thoracic or lumbar (List separately in addition to code for primary procedure)

Common Language Description

The CPT® Code 63057 refers to a surgical procedure involving a transpedicular approach for the decompression of the spinal cord, cauda equina, and/or nerve root(s), particularly in cases of a herniated intervertebral disc. This procedure is performed on a single segment of the thoracic or lumbar spine, with the option to list additional segments separately. The term "transpedicular" indicates that the approach involves the removal of part of one of the two pedicles, which are bony structures that project from the vertebra and help form the vertebral arch that encases the spinal cord. The procedure begins with a skin incision made at the lateral margin of the spinous process of the affected disc, followed by the elevation of paraspinal muscles to access the underlying structures. The lamina and facet joint are then exposed, allowing for the removal of specific bony portions to relieve pressure on the spinal cord and nerve roots. This detailed approach is crucial for addressing conditions such as herniated discs, where decompression is necessary to alleviate pain and restore function. The procedure is complex and requires careful manipulation of the spinal anatomy to ensure successful outcomes while minimizing risks to surrounding structures.

1. Indications

The procedure described by CPT® Code 63057 is indicated for specific conditions affecting the spinal cord and nerve roots. These indications include:

  • Herniated Intervertebral Disc - A condition where the inner gel-like core of the disc bulges out through a tear in the outer layer, potentially compressing nearby nerves or the spinal cord.
  • Spinal Stenosis - A narrowing of the spinal canal that can lead to pressure on the spinal cord and nerve roots, causing pain and neurological symptoms.
  • Bone Spurs - Bony growths that can develop on the vertebrae and contribute to nerve compression, often associated with degenerative disc disease.

2. Procedure

The procedure involves several critical steps to ensure effective decompression of the spinal structures. These steps include:

  • Step 1: Skin Incision - A skin incision is made at the lateral margin of the spinous process of the affected cervical disc to access the underlying spinal structures.
  • Step 2: Muscle Elevation - The paraspinal muscles are carefully elevated off the spinous process, lamina, and transverse process to expose the necessary anatomical landmarks for the procedure.
  • Step 3: Exposure of Lamina and Facet Joint - The lamina and facet joint are exposed, allowing the surgeon to visualize the area requiring decompression.
  • Step 4: Removal of Bony Structures - Using a high-speed drill, the medial portion of the facet and the lateral portion of the lamina are removed to create space for decompression.
  • Step 5: Pedicle Removal - The pedicle is partially removed to further expose the lateral margin of the spinal cord, facilitating access to the affected nerve structures.
  • Step 6: Identification of Nerve Root and Herniated Disc - The spinal nerve root and the herniated portion of the intervertebral disc are identified, which is crucial for targeted decompression.
  • Step 7: Excision of Bone Spurs - Any bone spurs present at the site of herniation are excised to relieve pressure on the nerve root and spinal cord.
  • Step 8: Creation of Cavity - A cavity is created and enlarged to remove ruptured disc fragments or bulging nucleus pulposus that may be impinging on the spinal cord, nerve root, and/or cauda equina.
  • Step 9: Additional Bone Removal - Additional bone may be removed as needed to ensure adequate relief of pressure on the affected nerve structures.
  • Step 10: Hemostasis and Closure - Bleeding is controlled, and the surgical wound is closed in layers to promote healing and minimize complications.

3. Post-Procedure

Post-procedure care following the transpedicular decompression involves monitoring for any complications, managing pain, and ensuring proper recovery. Patients may be advised to follow specific activity restrictions to allow for healing. Physical therapy may be recommended to aid in rehabilitation and restore function. Follow-up appointments are essential to assess the surgical site and the patient's recovery progress. Any signs of infection, increased pain, or neurological deficits should be reported to the healthcare provider immediately for further evaluation.

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
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).
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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).
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.)
