Official Description

Repair of nonunion or malunion, radius OR ulna; without graft (eg, compression technique)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25400 pertains to the surgical repair of a nonunion or malunion of the radius or ulna, specifically when this repair is performed without the use of a bone graft. A nonunion occurs when the fracture fragments fail to unite after an adequate period of healing, while a malunion refers to a situation where the fragments heal in an incorrect position, leading to potential complications. These complications can include osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement, which may result in functional impairment. During the procedure, the original fracture sites of the radius and/or ulna are surgically exposed to assess the condition of the nonunion or malunion. The evaluation determines the necessary repair technique, which may involve the application of internal fixation methods. In cases where a bone graft is not utilized, a compression plate may be employed to stabilize the fracture site. The procedure may also involve refracturing the bone to realign it properly in cases of malunion. The fixation device's stability and the alignment of the fracture are confirmed through radiographic imaging, ensuring that the repair is effective and that the bone is positioned correctly for optimal healing.

1. Indications

The procedure is indicated for the following conditions:

  • Nonunion of Fracture - This occurs when the fracture fragments do not unite after an adequate healing period, necessitating surgical intervention to promote healing.
  • Malunion of Fracture - This condition arises when the fracture heals in an improper alignment, which can lead to functional impairment and other complications, requiring correction through surgical repair.

2. Procedure

The surgical procedure for the repair of nonunion or malunion of the radius or ulna without a graft involves several key steps:

  • Exposure of Fracture Site - The initial step involves making an incision to expose the original fracture sites of the radius and/or ulna. This allows the surgeon to directly visualize the nonunion or malunion and assess the condition of the bone fragments.
  • Evaluation of Nonunion or Malunion - Once exposed, the surgeon evaluates the fracture site to determine the appropriate repair technique. This assessment is crucial for deciding whether internal fixation alone is sufficient or if additional measures, such as refracturing, are necessary.
  • Application of Internal Fixation - For a nonunion, a compression plate is placed over the fracture site and secured with lag screws to stabilize the fragments. In cases of malunion, the surgeon may refracture the bone to realign it properly and then apply internal fixation to maintain anatomical alignment.
  • Stability and Alignment Verification - After the fixation device is placed, the surgeon checks the stability of the fracture and verifies the alignment through radiographic imaging, ensuring that the repair is effective.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for signs of infection and ensuring proper healing. Patients may be advised on activity restrictions to avoid stress on the repaired area. Follow-up appointments are essential to assess the healing process through imaging studies and clinical evaluations. The expected recovery time may vary based on the individual’s health status and adherence to rehabilitation protocols.

LT Left side (used to identify procedures performed on the left side of the body)
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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
