LeFort II/III Osteoplasty - CDT Code Guide
Overview
CDT code D7948 refers to the LeFort II or LeFort III osteoplasty procedure, a complex surgical intervention performed by oral and maxillofacial surgeons. This procedure is typically indicated for patients with midface hypoplasia or retrusion, conditions that can affect facial symmetry and function. The surgery involves sectioning the upper jaw, making precise bone cuts, downfracturing, and segmenting the maxilla. The maxilla is then repositioned and fixed in place, followed by routine wound closure. Post-operative care is an integral part of the procedure, ensuring proper healing and monitoring for any complications. This code is crucial for accurately documenting and billing this intricate surgery, which plays a vital role in correcting facial deformities and improving patient outcomes.
When to Use This Code
- Patients with congenital midface hypoplasia requiring surgical correction
- Cases of traumatic injury leading to midface retrusion
- Patients undergoing orthognathic surgery for functional and aesthetic improvement
- Individuals with syndromic conditions affecting midface development
- Reconstructive surgery following tumor resection in the midface region
Documentation Requirements
- Detailed surgical report outlining the procedure steps
- Pre-operative and post-operative imaging studies
- Patient consent forms specific to the procedure
- Comprehensive patient history and diagnosis supporting the need for surgery
- Post-operative care instructions and follow-up visit documentation
Billing Considerations
When billing for D7948, it's important to note that this code does not include bone grafting, which should be billed separately if performed. Common modifiers such as -22 for increased procedural services may be applicable if the surgery is more complex than usual. Insurance pre-authorization is often required due to the procedure's complexity and cost. Frequency limitations may apply, and documentation must clearly justify the medical necessity of the surgery.
