The procedure described by CPT® Code 22634 refers to arthrodesis, which is a surgical technique aimed at fusing one or more lumbar vertebral joints. This procedure is typically indicated for treating conditions such as fractures or instability within the lumbar spine. The fusion is achieved using a combined posterior or posterolateral technique alongside a posterior interbody technique. The surgical approach involves making an incision in the lower back to access the affected lumbar vertebral joint(s). During the procedure, soft tissues are carefully dissected to expose the vertebrae, allowing for the removal of part of the lamina using a bone drill. The intervertebral disc is excised, and the joint space is meticulously prepared for the arthrodesis. In addition to the primary fusion, the procedure may involve other separately reportable interventions, such as fracture treatment or decompression, as necessary. The preparation for fusion includes addressing the transverse processes, facet joints, and/or laminae to facilitate the placement of a bone graft. This graft can be harvested from the iliac crest or another site, and allograft bone from a bone bank may also be utilized. The graft is strategically placed in the intervertebral joint space to promote the fusion of the vertebral bodies. Additional graft material may be applied to other areas of the vertebral joint, including the transverse processes, facet joints, or laminae, to ensure a successful fusion. To stabilize the joint, drill holes are created in the facets or spinous processes of each vertebra, and wires are threaded through the vertebrae. Alternatively, other internal fixation devices, which are separately reportable, may be inserted through the pedicles or facets. After the necessary procedures are completed, a drain may be placed, and the surgical wound is closed in layers. It is important to note that CPT® Code 22634 is specifically used for reporting the fusion of each additional interspace and vertebral segment, while CPT® Code 22633 is designated for the fusion of a single interspace of the lumbar spine.

The procedure described by CPT® Code 22634 is indicated for the following conditions:
The procedure for CPT® Code 22634 involves several critical steps to achieve successful arthrodesis:
Post-procedure care following arthrodesis using CPT® Code 22634 typically involves monitoring the patient for any signs of complications, such as infection or excessive bleeding. Patients may be advised to limit physical activity and follow specific rehabilitation protocols to support recovery. Pain management strategies will be implemented to ensure patient comfort during the healing process. Follow-up appointments will be necessary to assess the success of the fusion and to monitor the overall recovery progress. The healthcare team will provide guidance on when it is safe to resume normal activities and any restrictions that may be necessary during the recovery period.

| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | GC | This service has been performed in part by a resident under the direction of a teaching physician | 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). | 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. | 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. | 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. | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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). | 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). | 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. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CR | Catastrophe/disaster related | ET | Emergency services | LT | Left side (used to identify procedures performed on the left side of the body) | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | RT | Right side (used to identify procedures performed on the right side of the body) | SA | Nurse practitioner rendering service in collaboration with a physician | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
