Official Description

Closed treatment of mandibular fracture; with manipulation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 21451 refers to the closed treatment of a mandibular fracture that requires manipulation. This procedure is specifically indicated for cases where the fracture is minimally displaced, meaning that the bone fragments are not significantly out of alignment. In such instances, the physician will administer local anesthesia to ensure patient comfort during the procedure. The primary goal of this treatment is to manually reduce the fracture fragments back into their proper position without the need for surgical fixation. This is in contrast to CPT® Code 21450, which pertains to the evaluation of a nondisplaced mandibular fracture that does not require any manipulation or fixation. The use of radiographs is essential in both cases to confirm the presence of a fracture in the mandible, allowing for appropriate treatment planning and execution.

1. Indications

The closed treatment of a mandibular fracture with manipulation, as described by CPT® Code 21451, is indicated for the following conditions:

  • Minimally Displaced Mandibular Fracture This procedure is performed when the fracture of the mandible is minimally displaced, meaning the bone fragments are slightly misaligned but can be corrected through manual manipulation.
  • Confirmation of Fracture Radiographs are obtained to confirm the presence of a fracture in the mandible, which is essential for determining the appropriate treatment approach.

2. Procedure

The procedure for the closed treatment of a mandibular fracture with manipulation involves several key steps:

  • Step 1: Patient Preparation The patient is prepared for the procedure, which includes obtaining informed consent and ensuring that local anesthesia is administered as needed to minimize discomfort during the manipulation of the fracture.
  • Step 2: Radiographic Confirmation Radiographs are obtained to confirm the diagnosis of a mandibular fracture. This imaging is crucial for assessing the extent of the fracture and determining the appropriate course of action.
  • Step 3: Manual Reduction The physician manually reduces the fracture fragments. This involves carefully manipulating the bone fragments back into their proper alignment without the use of surgical fixation. The goal is to restore the normal anatomy of the mandible.
  • Step 4: Post-Reduction Assessment After the manipulation, the physician may reassess the alignment of the fracture through physical examination and possibly additional imaging to ensure that the fragments are properly positioned.

3. Post-Procedure

Following the closed treatment of a mandibular fracture with manipulation, the patient may be monitored for any immediate complications. Instructions regarding post-procedure care will be provided, which may include recommendations for pain management, dietary modifications, and follow-up appointments to assess healing. The patient is typically advised to avoid hard foods and activities that may stress the jaw during the initial recovery period. Regular follow-up visits may be necessary to ensure proper healing and to address any concerns that may arise during the recovery process.

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).
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.
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.
