Official Description

Amputation, leg, through tibia and fibula; open, circular (guillotine)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Guillotine amputation through the tibia and fibula, as described by CPT® Code 27882, is a surgical procedure typically indicated in cases of severe trauma or infection of the leg. This type of amputation is characterized by its open, circular technique, which is employed when the leg is heavily contaminated or when there is a significant infection that necessitates immediate intervention. The procedure aims to remove the affected limb while minimizing the risk of further complications associated with infection. The level of amputation is carefully determined based on the extent of the injury or the severity of the infection, ensuring that the procedure addresses the underlying issues effectively. During the operation, the surgeon meticulously marks the skin to facilitate the development of skin flaps, which are designed to be as distal as possible to optimize healing. The incision is made down to the deep fascia, allowing for retraction of the skin and subsequent layers. The circular incision around the tibia and fibula is performed with precision, and as the procedure progresses, nerves are transected upon encounter, and blood vessels are ligated and cut to control bleeding. The final step involves the transection of the tibia and fibula in alignment with the retracted muscle, leaving the stump open for dressing application. This open approach allows for monitoring and management of any potential infection. Once the risk of infection has subsided, a secondary closure or re-amputation at a higher level may be performed, which is reported separately.

1. Indications

Guillotine amputation through the tibia and fibula is indicated in specific clinical scenarios where immediate surgical intervention is necessary. The following conditions warrant this procedure:

  • Severe Trauma The procedure is often performed following significant injuries to the leg that may compromise the viability of the limb.
  • Heavily Contaminated Wounds In cases where the leg has sustained wounds that are heavily contaminated, a guillotine amputation may be required to prevent the spread of infection.
  • Severe Infection The presence of a severe infection in the leg that poses a risk to the patient's health may necessitate this type of amputation to remove infected tissue and prevent systemic complications.

2. Procedure

The guillotine amputation procedure involves several critical steps that are executed with precision to ensure the best possible outcome for the patient. The following outlines the procedural steps:

  • Step 1: Skin Marking The surgeon begins by marking the skin to delineate the area for the amputation. This marking is crucial as it allows for the development of skin flaps that can be created as distally as possible, which aids in future closure and healing.
  • Step 2: Skin Incision An incision is made through the marked skin down to the deep fascia. This incision is carefully executed to allow the skin to retract, providing access to the underlying structures.
  • Step 3: Muscle Incision The muscle surrounding the tibia and fibula is then incised in a circular fashion. This step is essential for exposing the bones and allows the muscle to retract, facilitating the subsequent steps of the procedure.
  • Step 4: Nerve Transection As the procedure progresses, nerves are transected as they are encountered. This is a necessary step to prevent pain and ensure that the amputation is complete.
  • Step 5: Blood Vessel Management Blood vessels in the area are carefully suture ligated and transected to control bleeding and minimize the risk of complications during and after the procedure.
  • Step 6: Bone Transection The tibia and fibula are then transected in line with the retracted muscle. This step marks the final removal of the limb, ensuring that the amputation is performed at the appropriate level based on the initial assessment of the injury or infection.
  • Step 7: Stump Management After the bones are transected, the stump is left open. Dressings are applied to the open stump to protect the area and allow for monitoring of any potential infection.

3. Post-Procedure

Post-procedure care following a guillotine amputation is critical for patient recovery and infection management. The open stump requires careful monitoring for signs of infection, and appropriate dressings must be maintained to protect the area. Once the risk of infection has diminished, a secondary closure or re-amputation at a higher level may be performed. This subsequent procedure is separately reportable and is essential for optimizing the healing process and preparing the patient for rehabilitation. The overall recovery will depend on the patient's condition, the extent of the initial injury or infection, and adherence to post-operative care instructions.

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.
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.
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).
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).
