Official Description

Allograft, includes templating, cutting, placement and internal fixation, when performed; osteoarticular, including articular surface and contiguous bone (List separately in addition to code for primary procedure)

Common Language Description

The CPT® Code 20932 refers to the procedure involving the insertion of an allograft, which is a graft of tissue obtained from a donor (often a cadaver) that is used to reconstruct a bone or soft tissue deficit. This procedure is particularly relevant in cases where there is a need to address significant bone loss due to various conditions such as tumors, osteochondral cysts, posttraumatic or degenerative arthritis, traumatic injuries, or avascular necrosis. The goal of using an allograft is to avoid limb amputation and to preserve the function of the limb by restoring the structural integrity of the affected area. The allograft itself typically consists of bone, cartilage, or other tissues that are anatomically similar to the tissue being replaced. During the procedure, the surgeon accesses the joint or bone area, resecting the damaged tissue down to viable healthy bone or tissue. The allograft is then sculpted to match the shape and size of the removed tissue, using the excised material as a template. Once shaped, the allograft is inserted into the prepared site and secured in place using various fixation methods, which may include rods, cerclage wires, intramedullary nails, plates, or screws. This procedure can involve either a partial or complete intercalary allograft, depending on the extent of the bone loss. The use of this code is essential when billing for the allograft procedure, as it is listed separately in addition to the primary procedure code for radical resection of the diseased bone or joint or for implant removal.

1. Indications

The procedure associated with CPT® Code 20932 is indicated for various conditions that result in significant bone or soft tissue deficits. These include:

  • Tumors - The presence of bone tumors may necessitate the removal of affected bone tissue, leading to the need for reconstruction with an allograft.
  • Osteochondral cysts - These cysts can cause damage to the bone and cartilage, requiring surgical intervention to restore joint function.
  • Posttraumatic or degenerative arthritis - Damage from arthritis can lead to substantial joint deterioration, making allograft reconstruction a viable option to restore joint integrity.
  • Traumatic injury - Severe injuries that compromise bone structure may require the use of an allograft to facilitate healing and maintain limb function.
  • Avascular necrosis - This condition, characterized by the death of bone tissue due to a lack of blood supply, may necessitate the use of an allograft to replace the affected area.

2. Procedure

The procedure for CPT® Code 20932 involves several critical steps to ensure the successful insertion of the allograft. These steps include:

  • Accessing the Joint or Bone Area - The surgeon begins by making an incision to access the affected joint or bone. This step is crucial for visualizing the area that requires reconstruction.
  • Resecting the Defect - The damaged or diseased tissue is carefully resected down to viable healthy bone or tissue. This ensures that the allograft will have a solid foundation for integration.
  • Sculpting the Allograft - The allograft is then sculpted to match the shape and size of the resected area, using the excised bone or tissue as a template. This step is vital for achieving a proper fit and function.
  • Inserting the Allograft - Once sculpted, the allograft is inserted into the prepared site. The precise placement is essential for optimal healing and function.
  • Fixating the Allograft - The allograft is secured in place using appropriate fixation hardware, which may include rods, cerclage wires, intramedullary nails, plates, or screws. This fixation is necessary to stabilize the graft during the healing process.

3. Post-Procedure

After the allograft procedure is completed, post-procedure care is essential for ensuring proper recovery and integration of the graft. Patients may require monitoring for signs of infection or complications at the surgical site. Rehabilitation may involve physical therapy to restore function and strength to the affected limb. The expected recovery time can vary based on the extent of the procedure and the individual patient's health status. Follow-up appointments will be necessary to assess the healing process and the success of the allograft integration into the surrounding bone or tissue.

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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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
