Official Description

Laminotomy (hemilaminectomy), with decompression of nerve root(s), including partial facetectomy, foraminotomy and/or excision of herniated intervertebral disc, reexploration, single interspace; each additional lumbar interspace (List separately in addition to code for primary procedure)

Common Language Description

The CPT® Code 63044 refers to a surgical procedure known as laminotomy or hemilaminectomy, which involves the re-exploration of a lumbar vertebra that has previously undergone decompression. This procedure is specifically aimed at relieving pressure on the nerve root(s) by removing portions of the facet joint and the bony arch that lies between the vertebral body and the spinal cord. The term 'laminotomy' indicates that a portion of the lamina, which is the bony structure that forms the back of the vertebral arch, is removed to access the spinal canal and the nerve roots. In addition to the decompression, this procedure may also include a partial facetectomy, which is the removal of part of the facet joint, and a foraminotomy, which is the widening of the foramen (the opening through which nerve roots exit the spinal column). Furthermore, if there is a herniated intervertebral disc present, the surgeon may excise this disc material to alleviate nerve compression. It is important to note that this code is used for each additional lumbar interspace treated during the procedure, and it is listed separately in addition to the code for the primary procedure. For procedures involving the cervical spine, different codes are utilized, specifically CPT® Code 63040 for the neck and CPT® Code 63042 for the lower back. If additional vertebrae are involved, CPT® Code 63043 is applicable for the neck, while CPT® Code 63044 is used for additional lumbar interspaces.

1. Indications

The procedure associated with CPT® Code 63044 is indicated for patients experiencing symptoms related to nerve root compression in the lumbar region. This may include conditions such as:

  • Herniated Intervertebral Disc - A condition where the disc material protrudes and compresses nearby nerve roots, causing pain, numbness, or weakness.
  • Spinal Stenosis - Narrowing of the spinal canal that can lead to nerve root compression and associated symptoms.
  • Degenerative Disc Disease - A condition where the intervertebral discs lose hydration and elasticity, potentially leading to nerve root irritation.
  • Facet Joint Osteoarthritis - Degeneration of the facet joints can contribute to nerve root compression, necessitating surgical intervention.

2. Procedure

The procedure for CPT® Code 63044 involves several key steps, which are detailed as follows:

  • Step 1: Anesthesia Administration - The patient is placed under appropriate anesthesia to ensure comfort and pain management during the procedure.
  • Step 2: Incision and Exposure - A surgical incision is made over the affected lumbar vertebra to access the spinal canal. The surrounding tissues are carefully retracted to expose the vertebra and the lamina.
  • Step 3: Laminotomy/Hemilaminectomy - A portion of the lamina is removed to create an opening in the vertebral arch, allowing access to the spinal canal and the nerve roots. This step is crucial for relieving pressure on the affected nerve root(s).
  • Step 4: Decompression of Nerve Root(s) - The surgeon identifies the compressed nerve root(s) and performs decompression by removing any obstructive tissue, including part of the facet joint and any herniated disc material that may be pressing on the nerve.
  • Step 5: Foraminotomy (if necessary) - If indicated, the foramen is widened to further alleviate pressure on the nerve root as it exits the spinal column.
  • Step 6: Closure - Once the decompression is complete, the surgical site is closed in layers, and the incision is sutured or stapled to promote healing.

3. Post-Procedure

After the completion of the procedure associated with CPT® Code 63044, patients are typically monitored in a recovery area until the effects of anesthesia wear off. Post-operative care may include pain management strategies, physical therapy recommendations, and instructions for activity restrictions to promote healing. Patients are advised to follow up with their healthcare provider to assess recovery progress and address any complications that may arise. The expected recovery time can vary based on individual health factors and the extent of the surgery performed.

80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
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).
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.
LT Left side (used to identify procedures performed on the left side of the body)
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).
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.
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.)
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
