Official Description

Open treatment of mandibular fracture; without interdental fixation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 21461 refers to the open treatment of a mandibular fracture without the use of interdental fixation. This procedure is typically performed by a physician to address fractures of the mandible, which is the lower jawbone. The process begins with the creation of an incision, which can be made either directly above the fracture site or intraorally through the mucosa, allowing for direct access to the fractured area. Once the fracture is isolated and visualized, the physician proceeds to reduce the fracture, which involves realigning the bone fragments to their proper anatomical position. To maintain this alignment, various fixation devices such as plates, wires, and screws are employed. It is important to note that this specific code is applicable only when intermaxillary fixation is not utilized; if such fixation is required, a different code (CPT® 21462) should be used, indicating that the jaws are wired together to stabilize the fracture during the healing process.

1. Indications

The open treatment of a mandibular fracture without interdental fixation, represented by CPT® Code 21461, is indicated for patients who have sustained a fracture of the mandible that requires surgical intervention. The procedure is typically performed in cases where the fracture is displaced, meaning the bone fragments are not aligned properly, and there is a need for direct visualization and stabilization of the fracture site. This treatment is essential for restoring the function and aesthetics of the jaw, alleviating pain, and preventing complications associated with improper healing of the fracture.

  • Mandibular Fracture A fracture of the lower jawbone that may result from trauma, such as a fall, accident, or physical altercation.
  • Displaced Fracture A fracture where the bone fragments are misaligned, necessitating surgical intervention for proper alignment.
  • Need for Surgical Stabilization Indicated when non-surgical methods are insufficient to ensure proper healing and function of the mandible.

2. Procedure

The procedure for the open treatment of a mandibular fracture without interdental fixation involves several critical steps to ensure effective treatment and stabilization of the fracture.

  • Step 1: Incision The physician begins by making an incision either directly above the fracture point or intraorally through the mucosa. This incision provides access to the fractured area of the mandible, allowing for direct visualization and manipulation of the bone fragments.
  • Step 2: Isolation and Visualization Once the incision is made, the physician isolates the fracture site. This involves carefully dissecting the surrounding tissues to expose the fracture, allowing for a clear view of the bone fragments that need to be realigned.
  • Step 3: Reduction of the Fracture After visualizing the fracture, the physician performs a reduction, which is the process of realigning the bone fragments to their normal anatomical position. This step is crucial for restoring the function of the mandible and ensuring proper healing.
  • Step 4: Stabilization To maintain the alignment achieved during the reduction, the physician uses fixation devices such as plates, wires, and/or screws. These devices are carefully placed to hold the mandible in the correct position, providing stability as the fracture heals.

3. Post-Procedure

After the open treatment of a mandibular fracture without interdental fixation, patients typically require post-procedure care to ensure proper healing and recovery. This may include monitoring for any signs of infection at the incision site, managing pain with prescribed medications, and following specific dietary recommendations to avoid placing undue stress on the jaw during the healing process. Patients are often advised to avoid hard or chewy foods and may need to follow up with their physician for regular assessments of the healing progress. Additionally, instructions regarding oral hygiene and care of the surgical site are provided to minimize complications and promote optimal recovery.

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).
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.
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).
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.
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
