Official Description

Osteoplasty, femur; shortening (excluding 64876)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 27465 refers to osteoplasty of the femur, specifically focusing on the shortening of the femur bone. Osteoplasty is a surgical intervention aimed at reshaping or reconstructing bone, and in this case, it involves the removal of a segment of the femur to achieve a desired reduction in length. Prior to the surgical procedure, the physician utilizes radiographic studies to accurately determine the precise locations for bone cuts, ensuring that the surgery is planned effectively to meet the patient's needs. During the operation, the femur is surgically exposed, allowing the surgeon to identify the specific sites for the bone cuts. Once these sites are established, the surgeon proceeds to excise a segment of the femur. After the segment is removed, the remaining ends of the femur are brought together and stabilized using internal fixation methods, which may include screws, plates, or other devices designed to maintain the alignment of the bone during the healing process. Alternatively, an external fixation device may be employed to provide additional support and stabilization. This procedure is critical for addressing various orthopedic conditions that may necessitate the shortening of the femur, thereby improving the patient's functional outcomes and overall quality of life.

1. Indications

The procedure described by CPT® Code 27465 is indicated for various orthopedic conditions that require the shortening of the femur. These may include:

  • Bone deformities that necessitate correction to restore proper alignment and function.
  • Leg length discrepancies where one leg is significantly longer than the other, leading to gait abnormalities and discomfort.
  • Post-traumatic deformities resulting from fractures or injuries that have healed improperly, requiring surgical intervention to restore normal anatomy.
  • Congenital conditions affecting the femur that may require surgical shortening to improve mobility and function.

2. Procedure

The procedure for CPT® Code 27465 involves several critical steps to ensure successful shortening of the femur:

  • Preoperative Planning begins with the physician conducting radiographic studies to determine the exact locations for the bone cuts. This planning phase is essential for achieving the desired shortening of the femur while minimizing complications.
  • Exposure of the Femur is performed by making an incision to access the femur. The surgical team carefully dissects through the surrounding tissues to expose the bone adequately.
  • Identification of Bone Cut Sites involves marking the specific areas on the femur where cuts will be made. This step is crucial for ensuring that the correct amount of bone is removed to achieve the intended shortening.
  • Bone Cutting and Excision is the next step, where the surgeon makes precise cuts in the femur at the identified sites. A segment of the bone is then excised, which reduces the length of the femur as planned.
  • Reconfiguration of the Bone follows the excision, where the remaining distal and proximal ends of the femur are brought into contact with each other. This step is vital for restoring the continuity of the bone.
  • Application of Internal Fixation is performed to stabilize the reconfigured bone. This may involve the use of screws, plates, or other internal fixation devices to maintain proper alignment during the healing process.
  • Alternative External Fixation may be considered if internal fixation is not suitable. An external fixation device can be applied to provide additional support and stabilization to the femur post-surgery.

3. Post-Procedure

After the completion of the osteoplasty procedure, patients typically require careful monitoring and follow-up care. Post-operative care may include pain management, physical therapy to restore mobility, and regular check-ups to assess the healing process. Patients are advised to follow specific weight-bearing restrictions and activity modifications as directed by their healthcare provider to ensure optimal recovery. The expected recovery time can vary based on individual factors, including the extent of the surgery and the patient's overall health. It is essential for patients to adhere to their post-operative instructions to minimize complications and promote successful healing of the femur.

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).
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.
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).
