Official Description

Removal of anterior instrumentation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 22855 involves the removal of anterior instrumentation, which refers to the surgical extraction of metal devices that have been previously implanted in the front (anterior) part of the spinal column. These instruments are typically used to stabilize the spine following surgical interventions or to support the healing process after spinal injuries or conditions. The removal of such instrumentation may be necessary due to various reasons, including complications, hardware failure, or the completion of the healing process. This procedure is performed by a qualified physician who specializes in spinal surgery and requires careful consideration of the patient's overall health and the specific circumstances surrounding the need for removal.

1. Indications

The removal of anterior instrumentation, as indicated by CPT® Code 22855, is performed under specific circumstances that necessitate the extraction of previously implanted hardware. The following are common indications for this procedure:

  • Complications from Hardware The presence of complications such as infection, pain, or discomfort associated with the implanted instrumentation may warrant its removal.
  • Hardware Failure Instances where the metal instruments have failed or become ineffective in providing the necessary support to the spinal column can lead to the decision to remove them.
  • Completion of Healing Once the spinal column has sufficiently healed, the physician may determine that the instrumentation is no longer required and proceed with its removal.

2. Procedure

The procedure for the removal of anterior instrumentation involves several critical steps to ensure the safety and effectiveness of the operation. Each step is performed with precision and care to minimize risks and promote optimal recovery.

  • Step 1: Anesthesia Administration The procedure begins with the administration of anesthesia to ensure the patient is comfortable and pain-free throughout the operation. This may involve general anesthesia or local anesthesia, depending on the specific case and physician preference.
  • Step 2: Incision The surgeon makes a carefully planned incision in the anterior region of the neck or abdomen, depending on the location of the instrumentation. This incision allows access to the spinal column and the implanted hardware.
  • Step 3: Exposure of Instrumentation Once the incision is made, the surgeon carefully dissects through the surrounding tissues to expose the anterior instrumentation. This step requires meticulous attention to avoid damaging nearby structures, such as nerves and blood vessels.
  • Step 4: Removal of Instrumentation After the instrumentation is fully exposed, the surgeon proceeds to remove the metal devices. This may involve unscrewing or detaching the hardware from the spinal column, ensuring that all components are safely extracted.
  • Step 5: Closure Following the successful removal of the instrumentation, the surgeon meticulously closes the incision using sutures or staples. Proper closure is essential to promote healing and reduce the risk of infection.

3. Post-Procedure

After the removal of anterior instrumentation, patients typically require post-procedure care to ensure a smooth recovery. This may include monitoring for any signs of complications, such as infection or excessive pain. Patients are often advised to follow specific guidelines regarding activity levels, including restrictions on heavy lifting or strenuous activities for a designated period. Follow-up appointments are essential to assess the healing process and address any concerns that may arise during recovery. The physician may also provide pain management strategies and rehabilitation recommendations to support the patient's return to normal activities.

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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.
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).
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.)
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).
