The procedure described by CPT® Code 21127 involves the augmentation of the mandibular body or angle, which is a surgical intervention aimed at enhancing the structure and contour of the lower jaw. This augmentation can be achieved through the use of a bone graft, which is a piece of bone taken from another part of the patient's body, or through the application of prosthetic material. The procedure is comprehensive, as it includes the process of obtaining the autograft, which is the harvesting of the patient's own bone. The physician typically performs this surgery through both intraoral and extraoral incisions, allowing for effective access to the mandible. The harvested bone graft is then carefully placed into the targeted area of the mandible and secured using wires or screws to ensure stability. Following the placement of the graft, all incisions are meticulously closed to promote healing and minimize scarring. This procedure is essential for patients requiring structural support in the mandible due to various conditions, including congenital defects, trauma, or previous surgical interventions.

The procedure described by CPT® Code 21127 is indicated for patients who require augmentation of the mandibular body or angle due to various conditions. These may include:
The procedure for CPT® Code 21127 involves several critical steps to ensure successful augmentation of the mandibular body or angle:
Post-procedure care for patients undergoing augmentation of the mandibular body or angle includes monitoring for any signs of complications, such as infection or graft failure. Patients are typically advised to follow a soft diet for a specified period to avoid stress on the surgical site. Pain management may be necessary, and the physician will provide instructions on the use of prescribed medications. Follow-up appointments are essential to assess healing and the integration of the graft. Patients should also be informed about the importance of maintaining oral hygiene to prevent infection at the surgical site.

| 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.) | 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. | LT | Left side (used to identify procedures performed on the left side of the body) |
