LeFort II or III with Bone Graft - CDT Code Guide
Overview
CDT code D7949 pertains to the LeFort II or LeFort III fracture repair with a bone graft, a complex oral and maxillofacial surgical procedure. This procedure involves the surgical reconstruction of midfacial fractures, often resulting from trauma, congenital deformities, or other pathological conditions. The process includes obtaining autografts, which are bone grafts taken from the patient's own body, to ensure compatibility and promote healing. This code is crucial for dental professionals dealing with severe facial injuries, as it provides a standardized way to document and bill for these intricate surgeries. Understanding the clinical context of D7949 is essential for both accurate diagnosis and effective treatment planning.
When to Use This Code
- Severe midfacial trauma requiring structural support and reconstruction
- Congenital deformities necessitating midface realignment
- Pathological conditions affecting the midfacial skeleton
- Post-traumatic reconstruction of the midface
- Complex facial surgeries involving bone grafting
Documentation Requirements
- Detailed surgical report outlining the procedure
- Pre- and post-operative imaging studies
- Documentation of the source and site of the autograft
