Official Description

Osteotomy of spine, including discectomy, anterior approach, single vertebral segment; each additional vertebral segment (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An osteotomy of the spine is a surgical procedure that involves the removal of a portion of a vertebra to correct spinal deformities, such as a flexion deformity. This procedure is performed through an anterior approach, which may involve incisions in the neck, thoracic region, thoracoabdominal area, abdomen, retropleural space, or retroperitoneal space, depending on the specific location of the deformity. The goal of the osteotomy is to realign the affected vertebral segment, thereby improving the overall function and stability of the spine while alleviating associated pain. During the procedure, soft tissues are carefully dissected to expose the vertebrae, and subperiosteal dissection is performed along the vertebral segment as necessary. Accessing the intervertebral disc may require the removal of a portion of the lamina. A curette is then utilized to excise the intervertebral disc or any disc fragments. A wedge of bone is resected from the vertebral body, which may also involve the excision of surrounding ligaments and spinous processes. The surgeon applies manual pressure at the osteotomy site to facilitate realignment, ensuring that nerve roots and other critical structures are protected throughout the process. Once the bony gap created by the wedge resection is closed, additional stabilization may be achieved through the use of bone grafts and/or spinal instrumentation. Post-operatively, a body cast or jacket may be applied to immobilize the spine as needed. This code, CPT® 22226, is specifically used to report each additional vertebral segment involved in the osteotomy procedure, following the primary procedure code for the first segment.

1. Indications

The osteotomy of the spine is indicated for various conditions that necessitate the correction of spinal deformities. These may include:

  • Flexion Deformity A condition where the spine is abnormally bent forward, leading to functional impairment and discomfort.
  • Spinal Instability Situations where the vertebrae are not properly aligned, causing pain and potential neurological issues.
  • Deformities Due to Trauma Injuries that result in misalignment or structural changes in the vertebrae.
  • Congenital Deformities Abnormalities present at birth that affect the normal structure and function of the spine.

2. Procedure

The procedure for spinal osteotomy involves several critical steps to ensure successful correction of the deformity. These steps include:

  • Incision An anterior approach is selected, and an incision is made in the appropriate area, which may include the neck, thoracic region, or abdomen, depending on the location of the deformity.
  • Soft Tissue Dissection The surgeon carefully dissects the soft tissues to expose the vertebrae, ensuring minimal damage to surrounding structures.
  • Subperiosteal Dissection This step involves dissecting along the vertebral segment to access the necessary areas for the osteotomy.
  • Accessing the Intervertebral Disc If required, a portion of the lamina may be removed to gain access to the intervertebral disc, which is crucial for the procedure.
  • Disc Removal A curette is utilized to excise the intervertebral disc or any fragments that may be causing issues.
  • Wedge Resection A wedge of bone is resected from the vertebral body, which may also involve the removal of surrounding ligaments and spinous processes to facilitate realignment.
  • Realignment The patient is repositioned, and manual pressure is applied at the osteotomy site to realign the vertebra, ensuring that nerve roots and vital structures are protected during this process.
  • Closure of Bony Gap Once the bony gap created by the wedge resection is closed, the surgeon may utilize bone grafts and/or spinal instrumentation to stabilize the spine.
  • Immobilization A body cast or jacket may be applied post-operatively to immobilize the spine and support the healing process.

3. Post-Procedure

After the spinal osteotomy, patients can expect a recovery period that may involve pain management and physical therapy. The application of a body cast or jacket is often necessary to immobilize the spine and promote healing. Regular follow-up appointments will be required to monitor the healing process and ensure that the spine is stabilizing correctly. Patients should be advised on activity restrictions and any signs of complications that may require immediate medical attention.

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
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).
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.
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.
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.
