Official Description

Open treatment of bimalleolar ankle fracture (eg, lateral and medial malleoli, or lateral and posterior malleoli, or medial and posterior malleoli), includes internal fixation, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 27814 refers to the open treatment of a bimalleolar ankle fracture, which involves the lateral and medial malleoli, the lateral and posterior malleoli, or the medial and posterior malleoli. This procedure includes the use of internal fixation when necessary. A bimalleolar ankle fracture is characterized by the involvement of two of the three bony prominences around the ankle joint: the lateral malleolus, which is the bony projection of the distal fibula on the outer side of the ankle; the medial malleolus, located at the distal end of the tibia on the inner side; and the posterior malleolus, also known as the posterior lip, which is the bony process at the back of the tibia. The open treatment approach allows for direct access to the fracture site, enabling the surgeon to properly align and stabilize the fractured bones. This is crucial for restoring the normal anatomy and function of the ankle joint, which is essential for weight-bearing and mobility. The procedure is performed under sterile conditions, and careful dissection is required to protect surrounding nerves and tissues during the operation.

1. Indications

The open treatment of a bimalleolar ankle fracture is indicated for patients who present with specific types of fractures involving the lateral and medial malleoli, the lateral and posterior malleoli, or the medial and posterior malleoli. These fractures typically occur due to trauma, such as falls, sports injuries, or accidents, leading to significant instability of the ankle joint. Indications for this procedure include:

  • Bimalleolar ankle fracture involving the lateral and medial malleoli, lateral and posterior malleoli, or medial and posterior malleoli.
  • Fractures that result in joint instability requiring surgical intervention to restore proper alignment and function.
  • Fractures that cannot be adequately treated with conservative management such as casting or splinting due to the severity of the injury.

2. Procedure

The procedure for the open treatment of a bimalleolar ankle fracture involves several critical steps to ensure proper alignment and stabilization of the fractured bones. The following procedural steps are performed:

  • Step 1: A lateral incision is made over the fracture site in the distal fibula to access the lateral malleolus. Care is taken to isolate and protect the branches of the superficial peroneal and sural nerves during dissection.
  • Step 2: Dissection continues until the periosteum is elevated, exposing the fracture site. The area is cleared of any debris to prepare for fracture reduction.
  • Step 3: The fracture is reduced and maintained using a bone clamp. Radiographic imaging is utilized to confirm that the reduction is satisfactory.
  • Step 4: If internal fixation is deemed necessary, a guidewire is inserted through the fracture site, followed by the application of internal fixation devices, such as a plate and screw system.
  • Step 5: A second incision is made over the medial malleolus to expose the fracture site. This area is also cleared of debris and reduced as needed, with internal fixation applied if required.
  • Step 6: In cases where the fracture involves the posterior malleolus, it may reduce spontaneously once the lateral or medial malleolus fracture is addressed. If it does not, the incision may be extended posteriorly to allow for active reduction and fixation of the posterior malleolus.
  • Step 7: Following the repair of the bimalleolar fracture, the stability of the ankle syndesmosis is verified to ensure proper alignment and function of the ankle joint.

3. Post-Procedure

Post-procedure care for patients who have undergone open treatment of a bimalleolar ankle fracture typically includes monitoring for complications such as infection, proper wound healing, and ensuring that the internal fixation remains stable. Patients may be advised to keep the affected limb elevated and to follow specific weight-bearing restrictions as determined by the surgeon. Rehabilitation may involve physical therapy to restore range of motion, strength, and function to the ankle joint. Follow-up appointments are essential to assess healing through imaging studies and to make any necessary adjustments to the treatment plan.

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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
56 Preoperative management only: when 1 physician or other qualified health care professional performed the preoperative care and evaluation and another performed the surgical procedure, the preoperative component may be identified by adding modifier 56 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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
