Official Description

Removal, under anesthesia, of external fixation system

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 20694 involves the removal of an external fixation system, which is a medical device used to stabilize fractures or other orthopedic conditions. This procedure is performed under general anesthesia to ensure the patient is completely unconscious and free from pain during the operation. The external fixation device typically consists of pins or wires that are inserted through the skin and into the bone, providing support and alignment to the affected area. During the removal process, the physician carefully extracts these pins or wires, which may be secured to the external device. Following the removal, any incisions made during the procedure are meticulously closed using sutures or Steri-strips to promote proper healing and minimize the risk of infection. This procedure is crucial for patients who have completed their treatment and no longer require the external fixation device for stabilization.

1. Indications

The procedure is indicated for patients who have undergone treatment involving an external fixation device and require its removal. This may include individuals with the following conditions:

  • Fracture Stabilization Patients who have had fractures stabilized with an external fixation device and have reached a point in their recovery where the device is no longer necessary.
  • Bone Healing Individuals whose bones have healed sufficiently, as determined by clinical evaluation and imaging studies, necessitating the removal of the fixation system.
  • Infection Management Patients who may have developed complications such as infection around the fixation site, requiring the removal of the device for treatment.

2. Procedure

The procedure for the removal of the external fixation system involves several key steps, each critical to ensuring a safe and effective outcome.

  • Preparation and Anesthesia The patient is first prepared for the procedure, which includes obtaining informed consent and ensuring that all necessary equipment is available. The patient is then placed under general anesthesia to ensure they are completely unconscious and free from pain during the procedure.
  • Accessing the Fixation Device Once the patient is anesthetized, the surgeon carefully examines the external fixation device to identify the pins or wires that need to be removed. This may involve palpating the area to locate the fixation points accurately.
  • Removal of Pins or Wires The surgeon proceeds to remove the pins or wires that have been inserted through the skin and into the bone. This is done with precision to minimize trauma to the surrounding tissues. The fixation device is detached, and the surgeon ensures that all components are completely removed.
  • Closure of Incisions After the removal of the external fixation system, any incisions made during the procedure are closed. This may involve suturing the skin or applying Steri-strips to promote healing. The surgeon ensures that the closure is secure to reduce the risk of infection and facilitate recovery.

3. Post-Procedure

Post-procedure care involves monitoring the patient as they recover from anesthesia. The surgical site is assessed for any signs of complications, such as excessive bleeding or infection. Patients are typically advised on how to care for the incision site, including keeping it clean and dry. Follow-up appointments may be scheduled to evaluate the healing process and to determine if any further treatment is necessary. Patients may also receive instructions regarding pain management and activity restrictions to ensure a smooth recovery.

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.
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).
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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.)
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
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.
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.
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).
