Official Description

Repair of nonunion or malunion, radius OR ulna; with autograft (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25405 involves the surgical repair of a nonunion or malunion of the radius or ulna, specifically when a bone graft is utilized. A nonunion occurs when the fracture fragments fail to heal together after an adequate period, while a malunion refers to the improper alignment of the fracture fragments, which can lead to various complications such as osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement. During the procedure, the surgeon exposes the original fracture sites of the radius and/or ulna to assess the condition of the nonunion or malunion. Depending on the evaluation, the repair may involve internal fixation techniques, which can be performed with or without the addition of a bone graft. In cases where internal fixation is applied without a graft, a compression plate may be used to stabilize the fracture. For nonunions, a compression plate is placed over the fracture site and secured with lag screws, while malunions may require refracturing and realigning the bone to restore anatomical alignment. If a bone graft is necessary, the site is prepared, which may involve refracturing the bone to facilitate healing. An autograft is typically harvested from the iliac crest, where a skin incision is made, and the muscle is stripped to expose the bone surface for harvesting cortical and/or cancellous bone. The harvested bone is then shaped to fit the defect, and internal fixation devices may be employed to secure the graft in place. This comprehensive approach aims to restore proper alignment and stability to the fractured bone, promoting effective healing and recovery.

1. Indications

The procedure is indicated for the following conditions:

  • Nonunion of the Fracture: This occurs when the fracture fragments do not unite after an adequate healing period, necessitating surgical intervention to promote healing.
  • Malunion of the Fracture: This condition arises when the fracture heals in an improper alignment, leading to potential complications such as pain, dysfunction, and deformity.

2. Procedure

The surgical procedure for the repair of nonunion or malunion of the radius or ulna with autograft involves several critical steps:

  • Step 1: Exposure of the Fracture Site The surgeon begins by making an incision to expose the original fracture sites of the radius and/or ulna. This allows for a thorough evaluation of the nonunion or malunion to determine the appropriate repair method.
  • Step 2: Evaluation and Preparation Once exposed, the surgeon assesses the condition of the fracture. For nonunions, a compression plate is placed over the fracture site and secured with lag screws. In cases of malunion, the bone may need to be refractured and realigned to restore proper anatomical positioning.
  • Step 3: Bone Graft Harvesting If a bone graft is required, the site of the nonunion or malunion is prepared, which may include refracturing the bone. An autograft is harvested from the iliac crest, where a skin incision is made, and the muscle is stripped to reveal the bone surface. The surgeon then harvests cortical and/or cancellous bone as needed.
  • Step 4: Graft Preparation and Placement The harvested bone is shaped to fit the defect in the radius or ulna. Cancellous bone may be morcellized and packed into the defect. Internal fixation devices, such as pins or wires, may be used to secure the bone graft in place.
  • Step 5: Stabilization of the Fracture After the graft is placed, a compression plate and screws or other internal fixation methods are utilized to stabilize the fracture. The stability of the fracture is checked, and alignment is verified through radiographic imaging to ensure proper positioning.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for signs of infection and ensuring proper healing of the bone. Patients may require follow-up imaging to assess the alignment and stability of the fracture and the success of the bone graft. Rehabilitation may be necessary to restore function and strength to the affected limb, and the healthcare team will provide specific instructions regarding activity restrictions and physical therapy as needed.

20703 Add-on Code MPFS Status: Active Code APC N Removal of drug-delivery device(s), intramedullary (List separately in addition to code for primary procedure)
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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
