Official Description

Revision of total elbow arthroplasty, including allograft when performed; humeral or ulnar component

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 24370 refers to the procedure known as the revision of total elbow arthroplasty, which may include the use of allograft tissue when performed. This surgical intervention is typically indicated for patients experiencing complications such as component loosening, joint instability, infection, or periprosthetic fractures that necessitate the replacement or adjustment of the elbow joint components. During the procedure, the surgeon reopens the previous incision over the elbow joint to access the underlying structures. The ulnar nerve is carefully identified and protected to prevent injury during the operation. The procedure involves the exposure of the ulnar component, followed by the removal of any loose bone cement that may be compromising the stability of the implant. The radial nerve is also identified and safeguarded as the humeral component is exposed and evaluated. If necessary, the surgeon may debride any infected or necrotic bone and tissue. Depending on the condition of the existing components, they may be replaced with new implants or repositioned to restore proper function. The final steps involve securing the components in place using allograft bone, cerclage wires, and/or bone cement, followed by the reattachment of ligaments and tendons, and the closure of the incision in layers. This procedure is crucial for restoring the functionality of the elbow joint and alleviating pain associated with the aforementioned complications.

1. Indications

The revision of total elbow arthroplasty, as described by CPT® Code 24370, is indicated for several specific conditions that may arise post-operatively. These include:

  • Component Loosening - This occurs when the prosthetic components become unstable within the bone, leading to pain and reduced function.
  • Joint Instability - Patients may experience a lack of stability in the elbow joint, which can result in difficulty with movement and increased risk of injury.
  • Infection - The presence of infection in the joint can necessitate revision surgery to remove infected tissue and components.
  • Periprosthetic Fracture - Fractures occurring around the prosthetic joint may require surgical intervention to repair or replace the damaged components.

2. Procedure

The procedure for the revision of total elbow arthroplasty involves several critical steps, which are detailed as follows:

  • Step 1: Incision and Exposure - The surgeon begins by incising the old surgical incision over the elbow joint. This allows access to the underlying soft tissues, which are carefully dissected to reveal the ulnar nerve, ensuring it is identified and protected throughout the procedure.
  • Step 2: Ulnar Component Exposure - The ulnar component of the prosthesis is then exposed. The subperiosteum along the ulna is carefully dissected to a point just beyond the tip of the implant, facilitating access to the area where the component is seated.
  • Step 3: Cement Removal - Any loose bone cement surrounding the ulnar component is meticulously removed to prepare for the evaluation and potential replacement of the implant.
  • Step 4: Humeral Component Exposure - The radial nerve is identified and protected, followed by the exposure of the humeral component. Similar to the ulnar component, loose cement is removed to ensure a stable environment for the revision.
  • Step 5: Evaluation and Debridement - The surgeon evaluates both the ulnar and humeral components. If infection or necrotic bone is present, debridement is performed to remove any compromised tissue.
  • Step 6: Component Replacement or Repositioning - Depending on the condition of the components, they may be exchanged for new implants or repositioned to restore proper alignment and function.
  • Step 7: Securing Components - The humeral and ulnar components are secured in place using allograft bone, cerclage wires, and/or bone cement to ensure stability and proper integration with the surrounding bone.
  • Step 8: Joint Assembly - The components are locked together with a pin to create a hinged prosthetic joint, allowing for functional movement.
  • Step 9: Soft Tissue Closure - Ligaments and tendons are reattached, and the triceps muscle is medialized. A subcutaneous pocket is created for the ulnar nerve, which is then placed between subcutaneous fat and fascia near the medial epicondyle.
  • Step 10: Final Closure - The fascia and skin are closed in layers to ensure proper healing and minimize scarring.
  • Step 11: Post-Operative Care - The arm is fully extended and placed in a splint to immobilize the joint during the initial recovery phase.

3. Post-Procedure

After the revision of total elbow arthroplasty, patients can expect a recovery period that may involve pain management, physical therapy, and regular follow-up appointments to monitor healing. The arm will typically be immobilized in a splint to allow for proper healing of the surgical site and stabilization of the newly positioned or replaced components. Patients should be advised on activity restrictions and signs of complications, such as increased pain, swelling, or signs of infection, which should be reported to their healthcare provider promptly. The overall goal of the procedure is to restore function and alleviate pain associated with the previous elbow joint issues.

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).
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).
