Official Description

Repair, nonunion or malunion, femur, distal to head and neck; with iliac or other autogenous bone graft (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 27472 involves the surgical repair of a nonunion or malunion of the femur, specifically located distal to the head and neck of the femur. 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 pain and functional impairment for the patient. During the procedure, the original fracture site is surgically exposed to assess the condition of the nonunion or malunion. The surgeon determines the appropriate method of repair, which may involve the use of an autogenous bone graft to fill any bone defects and promote healing. This graft is typically harvested from the iliac crest, and the procedure includes obtaining the graft as part of the overall surgical intervention. The use of a bone graft is essential in this context, as it provides the necessary biological material to facilitate the healing process, especially in cases where the fracture has not healed properly on its own.

1. Indications

The procedure described by CPT® Code 27472 is indicated for the following conditions:

  • Nonunion of the femur - This condition occurs when the fracture fragments do not unite after an adequate healing period, necessitating surgical intervention to promote healing.
  • Malunion of the femur - This situation arises when the fracture heals in an improper alignment, leading to functional impairment and potential complications that require correction through surgical means.

2. Procedure

The surgical procedure for CPT® Code 27472 involves several critical steps to effectively repair the nonunion or malunion of the femur:

  • Step 1: Exposure of the fracture site - The surgeon begins by making an incision to expose the original fracture site in the femur. This allows for direct visualization and assessment of the nonunion or malunion, which is essential for determining the appropriate repair technique.
  • Step 2: Evaluation of the nonunion or malunion - Once the fracture site is exposed, the surgeon evaluates the condition of the bone fragments. This assessment helps in deciding whether a bone graft is necessary and what type of fixation will be used to stabilize the fracture.
  • Step 3: Harvesting the bone graft - If a bone graft is required, the surgeon proceeds to harvest an autogenous bone graft, typically from the iliac crest. A skin incision is made over the iliac crest, and the muscle is carefully stripped away to expose the bone surface. The surgeon then removes cortical and/or cancellous bone, which will be used to fill the defect at the fracture site.
  • Step 4: Preparing the bone defect - The site of the nonunion or malunion is prepared for the graft. This may involve refracturing the bone to ensure proper alignment and fit of the graft. The harvested bone graft is then shaped to match the size and configuration of the defect, or cancellous bone may be morcellized and packed into the defect.
  • Step 5: Securing the bone graft - The bone graft is secured in place using internal fixation methods, such as pins or wires, as needed. Additionally, a compression plate and screws or other forms of internal fixation are applied to stabilize the fracture and maintain anatomical alignment during the healing process.
  • Step 6: Verification of stability and alignment - After the fixation devices are in place, the surgeon checks the stability of the fracture and verifies the alignment radiographically to ensure that the repair is successful and that the bone is positioned correctly for optimal healing.

3. Post-Procedure

Post-procedure care for patients undergoing the repair of a nonunion or malunion of the femur typically includes monitoring for signs of healing and complications. Patients may be advised to limit weight-bearing activities on the affected limb for a specified period to allow for proper healing. Follow-up appointments are essential to assess the healing process through imaging studies, such as X-rays, to confirm that the bone is healing correctly and that the alignment is maintained. Pain management and rehabilitation exercises may also be part of the recovery plan to restore function and strength to the affected limb.

This is a primary code that can be used with these additional add-on codes.

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.
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).
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
CR Catastrophe/disaster related
GC This service has been performed in part by a resident under the direction of a teaching physician
