Official Description

Amputation, arm through humerus; re-amputation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Re-amputation of the arm through the humerus, as described by CPT® Code 24930, refers to a surgical procedure where the arm is amputated at a higher level than a previous amputation. This procedure is typically performed to eliminate diseased, infected, or nonviable tissue that poses a risk to the patient's health. Additionally, re-amputation may be necessary to create a healthy stump that can accommodate a prosthesis. The procedure involves careful planning and execution, beginning with the marking of incision lines on the skin to ensure precision. The surgical team incises the skin and underlying soft tissue, exposing the muscles, which are then isolated and divided by muscle group. Critical structures such as nerves and blood vessels are identified and handled with care to prevent complications. The humerus, the bone of the upper arm, is exposed, and periosteal flaps are created to facilitate a clean transection of the bone. The remaining bone is then covered with muscle and skin flaps to promote healing and functionality. This detailed approach is essential for ensuring the best possible outcome for the patient, particularly in terms of recovery and the potential use of a prosthetic limb.

1. Indications

The procedure of re-amputation of the arm through the humerus is indicated in specific clinical scenarios where the integrity of the arm is compromised. The following conditions may warrant this surgical intervention:

  • Disease The presence of disease in the arm that cannot be managed through conservative treatment methods.
  • Infection Severe infections that threaten the viability of the arm and cannot be resolved with antibiotics or other treatments.
  • Nonviable Tissue The existence of nonviable tissue that poses a risk of further complications, such as necrosis or systemic infection.
  • Prosthetic Fit The need to create a healthy stump that is suitable for the fitting of a prosthesis, enhancing the patient's quality of life.

2. Procedure

The re-amputation procedure involves several critical steps to ensure a successful outcome. Each step is performed with precision and care to minimize complications and promote healing.

  • Step 1: Marking Incision Lines The surgical team begins by marking the incision lines on the patient's skin, which guides the subsequent surgical approach and ensures accuracy in the re-amputation site.
  • Step 2: Incision and Exposure The skin and underlying soft tissue are incised along the marked lines. This initial incision allows access to the muscles and deeper structures of the arm.
  • Step 3: Muscle Isolation and Division Once the soft tissue is incised, the muscles are exposed. The surgeon isolates the muscles by group and divides them to facilitate access to the underlying nerves and blood vessels.
  • Step 4: Nerve and Blood Vessel Management Critical structures such as nerves and blood vessels are identified and carefully isolated. The surgeon ensures that nerves are separated from arteries to prevent pulsatile irritation. Nerves are then transected and allowed to retract into the surrounding soft tissue, while blood vessels are ligated and transected to control bleeding.
  • Step 5: Humerus Exposure and Transection The humerus is exposed, and periosteal flaps are created to protect the surrounding tissue. The humerus is then transected at the level of the periosteal flaps, ensuring a clean cut.
  • Step 6: Muscle and Skin Closure The periosteal flaps are sutured over the remaining bone, and antagonistic muscle groups are sutured to each other and anchored to the periosteum. This technique ensures that the remaining portion of the humerus is completely enveloped in muscle. Finally, skin flaps are fashioned and sutured over the muscle to complete the procedure.

3. Post-Procedure

After the re-amputation procedure, the patient will require careful monitoring and post-operative care to ensure proper healing. This may include pain management, wound care, and physical therapy to promote recovery and mobility. The surgical site will need to be kept clean and dry, and any signs of infection or complications should be reported to the healthcare provider immediately. The patient may also begin the process of fitting for a prosthesis, depending on their recovery progress and overall health status.

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.
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.
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.)
