Official Description

Application of a multiplane (pins or wires in more than 1 plane), unilateral, external fixation system (eg, Ilizarov, Monticelli type)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 20692 refers to the application of a multiplane external fixation system, which is a specialized device used to stabilize fractures or joint injuries. This procedure is performed unilaterally, meaning it is applied to one side of the body. The term "multiplane" indicates that the fixation system involves the use of pins or wires that are positioned in more than one plane, providing enhanced stability and support to the affected area. The external fixation device, which may include systems such as the Ilizarov or Monticelli types, is designed to hold the bones in the correct position while they heal. This method is particularly useful in complex fractures or when traditional casting is insufficient. The procedure typically requires the patient to be under general anesthesia, ensuring comfort and immobility during the application of the fixation system. The use of this code is essential for accurate medical billing and coding, as it distinguishes between different types of external fixation systems based on their complexity and the planes involved.

1. Indications

External fixation systems, such as those described by CPT® Code 20692, are indicated for various conditions and situations where stabilization of a fracture or joint injury is necessary. The following are the explicitly provided indications for this procedure:

  • Fractures The application of a multiplane external fixation system is indicated for complex fractures that require stabilization to promote proper healing.
  • Joint Injuries This procedure is also indicated for joint injuries where traditional methods of stabilization may not provide adequate support.
  • Bone Deformities The use of external fixation may be indicated in cases of bone deformities that require correction and stabilization during the healing process.

2. Procedure

The procedure for applying a multiplane external fixation system involves several critical steps to ensure proper stabilization of the affected area. The following procedural steps are outlined:

  • Step 1: Anesthesia Administration The patient is placed under general anesthesia to ensure comfort and immobility during the procedure. This is a crucial step as it allows the physician to work without causing pain or distress to the patient.
  • Step 2: Bone Preparation The physician uses a drill to create small holes through the affected bones. This preparation is essential for the subsequent placement of wires or pins, which will anchor the external fixation device securely to the bone.
  • Step 3: Placement of Pins or Wires Wires or pins are then inserted through the skin and into the holes created in the bone. This step is critical as it establishes the connection between the bone and the external fixation device, providing the necessary stability.
  • Step 4: Attachment of the External Fixation Device The external fixation device is then attached to the pins or wires. This device is designed to hold the bones in the correct position, allowing for proper alignment and stabilization during the healing process.

3. Post-Procedure

After the application of the multiplane external fixation system, the patient will require specific post-procedure care to ensure optimal healing and recovery. The physician will typically provide instructions regarding the care of the fixation device, including how to keep the area clean and monitor for any signs of infection. Regular follow-up appointments will be necessary to assess the healing process and make any adjustments to the fixation system as needed. Patients may also be advised on weight-bearing restrictions and rehabilitation exercises to promote recovery while minimizing the risk of complications. Overall, careful monitoring and adherence to post-procedure guidelines are essential for successful outcomes following this 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).
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.
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.
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.
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.
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).
