Official Description

Osteotomy of spine, posterior or posterolateral approach, 1 vertebral segment; cervical

© 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 specifically performed using a posterior or posterolateral approach, which means that the incision is made either directly over the affected vertebral segment or just to the side of it. The goal of the osteotomy is to realign the vertebral segment, thereby improving the overall function and stability of the spine while also alleviating pain associated with the deformity. During the procedure, the fascia is incised, and a subperiosteal dissection is carried out along the spinal process, lamina, transverse processes, and rib head of the vertebral segment as necessary. A wedge of bone is then resected, which may involve the removal of parts of the supraspinatus and infraspinatus ligaments and spinous processes. The surgeon carefully repositions the patient and applies manual pressure at the osteotomy site to facilitate the realignment of the vertebra, ensuring that nerve roots and other critical structures are kept in view to prevent any impingement. After the bony gap created by the wedge resection is closed, additional stabilization may be achieved through separately reportable bone grafts and/or spinal instrumentation. To ensure proper healing and immobilization of the spine, a body cast or jacket may be applied as needed. This procedure is specifically coded as CPT® Code 22210 for the osteotomy of one cervical vertebral segment, with additional codes available for thoracic and lumbar segments.

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 pain and functional limitations.
  • Spinal Instability Situations where the vertebrae are not properly aligned, causing instability and potential neurological compromise.
  • Deformities Due to Trauma Injuries that result in misalignment or deformity of the vertebrae, requiring surgical intervention to restore normal anatomy.
  • Congenital Deformities Birth defects that affect the structure of the spine, necessitating surgical correction to improve function and quality of life.

2. Procedure

The procedure for a spinal osteotomy involves several critical steps to ensure successful correction of the deformity. The following outlines the procedural steps:

  • Step 1: Incision An incision is made over the affected vertebral segment or just lateral to it, allowing access to the spine.
  • Step 2: Fascia Incision The fascia covering the muscles and tissues is incised to expose the underlying structures of the spine.
  • Step 3: Subperiosteal Dissection A subperiosteal dissection is performed along the spinal process, lamina, transverse processes, and rib head of the vertebral segment as needed to access the bone.
  • Step 4: Resection of Bone Wedge A wedge of bone is resected from the vertebra, which may include portions of the supraspinatus and infraspinatus ligaments and spinous processes to facilitate realignment.
  • Step 5: Repositioning and Manual Pressure The patient is carefully repositioned, and manual pressure is applied at the osteotomy site until the opposing ligaments tear, allowing for the necessary manipulation of the vertebra.
  • Step 6: Visualization of Nerve Roots Throughout the procedure, nerve roots and other vital structures are kept under direct visualization to prevent any impingement during the manipulation of the vertebra.
  • Step 7: Closure of Bony Gap Once the bony gap created by the wedge resection has been closed, stabilization may be achieved through the use of separately reportable bone grafts and/or spinal instrumentation.
  • Step 8: Application of Body Cast or Jacket A body cast or jacket is applied as needed to immobilize the spine and support the healing process.

3. Post-Procedure

After the spinal osteotomy, patients typically require careful monitoring and follow-up care to ensure proper healing. Post-procedure care may include pain management, physical therapy, and regular assessments to evaluate spinal stability and recovery. The application of a body cast or jacket is crucial for immobilization, which aids in the healing of the spine. Patients are advised to follow specific activity restrictions to prevent complications and promote optimal recovery. The duration of recovery may vary based on individual circumstances and the extent of the procedure performed.

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.
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).
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.
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).
