Official Description

Open treatment of fracture of weight bearing articular surface/portion of distal tibia (eg, pilon or tibial plafond), with internal fixation, when performed; of tibia only

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A fracture of the weight-bearing articular surface of the distal tibia, commonly known as a tibial plafond or tibial pilon fracture, involves a significant injury to the lower leg. This type of fracture occurs when the distal end of the tibia, which is the larger of the two bones in the lower leg, sustains a high-energy impact, often resulting from falls from heights or motor vehicle accidents. The term "articular surface" refers to the area of the bone that forms a joint with another bone, in this case, the ankle joint. When the fracture occurs, it can lead to severe damage not only to the bone but also to the surrounding soft tissues and articular cartilage, which are crucial for joint function. During the injury, the distal tibia absorbs the force, which can exceed the bone's yield point, leading to shattering. Depending on the position of the foot at the time of impact, the fibula, the smaller bone located alongside the tibia, may also be fractured. The resulting trauma can cause significant injury to the soft tissues, including subcutaneous tissue and skin, which may complicate the healing process. The open treatment of this fracture involves surgical intervention to repair the bone and restore its integrity. This procedure may include the use of internal fixation devices, such as plates and screws, to stabilize the fracture and promote healing. The surgical approach is critical, as it aims to minimize soft tissue damage while ensuring proper alignment and stability of the fractured bone. The complexity of tibial pilon fractures necessitates careful planning and execution during the surgical procedure to achieve optimal outcomes for the patient.

1. Indications

The open treatment of a fracture of the weight-bearing articular surface of the distal tibia is indicated in the following scenarios:

  • High-Energy Trauma: This procedure is typically performed following high-energy injuries, such as those resulting from falls from significant heights or severe motor vehicle accidents, which lead to tibial pilon fractures.
  • Severe Articular Damage: Indications include cases where there is substantial damage to the articular cartilage and surrounding soft tissues at the ankle joint, necessitating surgical intervention for proper healing.
  • Fracture Displacement: The procedure is indicated when there is significant displacement of the fracture fragments that cannot be adequately managed through conservative treatment methods.
  • Joint Instability: If the fracture results in instability of the ankle joint, surgical fixation is required to restore joint function and stability.

2. Procedure

The open treatment of a fracture of the weight-bearing articular surface of the distal tibia involves several critical procedural steps:

  • Step 1: Incision and Exposure An incision is made over the anterior or anteromedial aspect of the ankle joint to access the fractured tibia. Care is taken to isolate and protect the neurovascular structures in the area to prevent any damage during the procedure.
  • Step 2: Fracture Debridement The fracture site is exposed, and any debris is cleared from the area to ensure a clean surgical field. This step is essential for proper visualization and assessment of the fracture.
  • Step 3: Fracture Reduction A femoral distraction device may be utilized to assist in the reduction of the fracture and to restore the proper length of the tibia. The articular surface is carefully restored with minimal soft tissue dissection to preserve surrounding structures.
  • Step 4: Internal Fixation Internal fixation is applied as necessary, typically using a buttress plate and screws. Additional interfragmentary screws may be used to enhance stability and support the fracture site.
  • Step 5: Joint Stability Assessment After fixation, the stability of the joint is thoroughly checked to ensure that the fracture is adequately stabilized and that the joint can function properly post-surgery.
  • Step 6: Wound Closure The surgical site is irrigated to reduce the risk of infection, and the incision is closed in layers to promote optimal healing.

3. Post-Procedure

Post-procedure care following the open treatment of a tibial plafond fracture includes monitoring for signs of infection, managing pain, and ensuring proper immobilization of the affected limb. Patients may require physical therapy to regain strength and mobility in the ankle joint as healing progresses. Follow-up appointments are essential to assess the healing of the fracture and the stability of the fixation. The expected recovery time can vary based on the severity of the fracture and the individual patient's healing response, but adherence to post-operative instructions is crucial for optimal outcomes.

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).
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).
