Official Description

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

© 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 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 tearing of opposing ligaments, all while ensuring that nerve roots and other critical structures are visible and protected from any potential 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 post-operatively. This procedure is specifically coded as CPT® 22212 for the osteotomy of one thoracic vertebral segment, with related codes available for cervical and lumbar segments as well as for additional vertebral segments.

1. Indications

The osteotomy of the spine, specifically CPT® Code 22212, is indicated for various conditions that necessitate the correction of spinal deformities. These indications 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 Spinal deformities resulting from traumatic injuries that require surgical intervention to restore normal alignment.
  • Congenital Deformities Abnormalities present at birth that affect the structure and function of the spine.

2. Procedure

The procedure for a spinal osteotomy using CPT® Code 22212 involves several critical steps to ensure successful correction of the deformity. The following procedural steps are performed:

  • Step 1: Incision An incision is made over the affected thoracic vertebral segment or just lateral to it, allowing access to the spine.
  • Step 2: Fascia Incision The fascia covering the area is incised to expose the underlying structures, facilitating further dissection.
  • 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: Wedge Resection A wedge of bone is resected from the vertebra, which may include portions of the supraspinatus and infraspinatus ligaments and spinous processes, to create a gap for realignment.
  • Step 5: Manual Pressure Application The patient is carefully repositioned, and manual pressure is applied at the osteotomy site to facilitate the tearing of opposing ligaments while ensuring that nerve roots and other vital structures are under direct visualization.
  • Step 6: Closing the Bony Gap Once the bony gap created by the wedge resection has been closed, stabilization of the spine may be achieved through the use of separately reportable bone grafts and/or spinal instrumentation.
  • Step 7: Immobilization 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 procedure, patients are typically monitored for any complications and provided with post-operative care instructions. Expected recovery may involve a period of immobilization using a body cast or jacket to ensure proper healing of the spine. Patients may also require physical therapy to regain strength and mobility. Follow-up appointments are essential to assess the healing process and to make any necessary adjustments to the treatment plan. It is important for patients to adhere to the post-operative care guidelines to optimize recovery and minimize the risk of complications.

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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure 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.
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).
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.
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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.)
