Official Description

Computer-assisted musculoskeletal surgical navigational orthopedic procedure, with image-guidance based on CT/MRI images (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A computer-assisted musculoskeletal surgical navigation orthopedic procedure is a sophisticated technique that utilizes advanced imaging technology, specifically CT (Computed Tomography) or MRI (Magnetic Resonance Imaging) images, to guide orthopedic surgeons during complex surgical interventions. This procedure is particularly beneficial for operations such as joint replacements, including arthroplasty, or the fixation of fractures in the femur or pelvis. By employing computer-assisted navigation systems, surgeons can achieve enhanced precision, which is crucial for the successful outcome of intricate orthopedic surgeries. The use of these systems not only improves surgical accuracy but also contributes to reduced operative time, minimized blood loss, and a quicker recovery period for patients post-surgery. The process of computer-assisted surgical navigation is methodical and consists of three primary steps: data acquisition, registration, and tracking. Initially, tracker pins are strategically placed at specific anatomical sites, followed by the acquisition of fluoroscopic, CT, or MRI images. These images serve as a foundation for the subsequent registration techniques, which correlate the anatomical surface data with the bony structures present in the surgical field. A computer-generated model is then created from the radiographic images and aligned with the surface data points. Throughout the surgical procedure, the computer-assisted navigation system continuously tracks the position and orientation of surgical instruments and/or internal fixation devices, ensuring that the surgeon can perform the operation with optimal accuracy and safety.

1. Indications

The computer-assisted musculoskeletal surgical navigation orthopedic procedure is indicated for various complex orthopedic conditions and surgical interventions. These include:

  • Joint Replacement (Arthroplasty) This procedure is often performed for patients suffering from severe joint degeneration, typically due to conditions such as osteoarthritis or rheumatoid arthritis, where traditional surgical methods may pose higher risks.
  • Fracture Fixation Specifically for complex fractures of the femur or pelvis, where precise alignment and stabilization are critical for optimal healing and functional recovery.

2. Procedure

The computer-assisted musculoskeletal surgical navigation orthopedic procedure involves several detailed steps to ensure accuracy and effectiveness during surgery. These steps include:

  • Step 1: Data Acquisition Initially, the surgeon places tracker pins at predetermined anatomical sites on the patient. Following this, fluoroscopic, CT, or MRI images are obtained to create a comprehensive view of the surgical area. This imaging is crucial as it provides the necessary anatomical information required for the subsequent steps.
  • Step 2: Registration Once the images are acquired, registration techniques are employed to correlate the anatomical surface data obtained from the imaging with the actual bony anatomy present in the surgical field. This step is vital as it ensures that the computer-generated model accurately reflects the patient's unique anatomy.
  • Step 3: Tracking After registration, a computer-generated model is prepared from the radiographic images and aligned with the surface data points. During the surgical procedure, the computer-assisted navigational system tracks the position and orientation of surgical tools and/or internal fixation devices. This real-time tracking allows the surgeon to navigate with precision, enhancing the overall safety and effectiveness of the procedure.

3. Post-Procedure

Post-procedure care following a computer-assisted musculoskeletal surgical navigation orthopedic procedure typically involves monitoring the patient for any immediate complications and ensuring proper recovery. Patients may experience a reduced recovery time due to the minimally invasive nature of the procedure. Rehabilitation protocols will be established based on the specific surgery performed, focusing on restoring mobility and strength. Follow-up appointments are essential to assess healing and to make any necessary adjustments to the rehabilitation plan. Additionally, the surgical team will provide instructions regarding pain management, activity restrictions, and signs of potential complications that the patient should monitor during their recovery period.

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.
GZ Item or service expected to be denied as not reasonable and necessary
GA Waiver of liability statement issued as required by payer policy, individual case
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).
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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.)
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.
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.
