LeFort I (Maxilla Segmented) - CDT Code Guide
Overview
CDT code D7947 pertains to the LeFort I osteotomy procedure, specifically when the maxilla is segmented. This surgical intervention is often necessary for correcting maxillary deficiencies or deformities, facilitating proper alignment and occlusion. The procedure typically involves surgically assisted palatal expansion without a downfracture, which is crucial for patients requiring maxillary expansion due to congenital or acquired conditions. Dental professionals should note that this code requires detailed reporting, as it involves reduced service when compared to full osteotomy procedures. Understanding the clinical context and patient-specific needs is essential for the appropriate application of this code.
When to Use This Code
- When performing surgically assisted palatal expansion without downfracture.
- In cases of maxillary deficiency requiring segmentation for proper alignment.
- For patients with congenital maxillary deformities needing surgical intervention.
- During orthognathic surgery planning where maxillary segmentation is indicated.
- In conjunction with orthodontic treatment plans requiring surgical assistance.
Documentation Requirements
- Detailed surgical report outlining the procedure specifics.
- Pre-operative and post-operative imaging to support the need for segmentation.
- Patient consent forms acknowledging understanding of the procedure.
- Clinical notes describing the diagnosis and rationale for the surgery.
- Documentation of any complications or additional procedures performed.
Billing Considerations
When billing for D7947, ensure that the procedure is well-documented as 'by report' due to its reduced service nature. Be aware of potential frequency limitations imposed by insurance providers. Common modifiers may include those indicating bilateral procedures or additional complexity. Always verify with the patient's insurance for pre-authorization requirements and coverage specifics.
