Transseptal Fiberotomy - CDT Code Guide
Overview
CDT Code D7291 refers to the transseptal fiberotomy/supra crestal fiberotomy procedure. This surgical intervention involves severing the supraosseous connective tissue attachment around the teeth. It is typically performed when there are adjacent teeth, requiring the involvement of at least three teeth for a single tooth fiberotomy. The procedure is conducted within the gingival sulcus, ensuring that the root surface remains uninstrumented. This allows the area to heal through the reattachment of connective tissue to the root surface where viable periodontal tissue is present. This procedure is often utilized in orthodontic treatments to prevent relapse by reducing the tension in the gingival fibers.
When to Use This Code
- During orthodontic treatment to prevent relapse after tooth movement.
- When there is a need to reduce gingival fiber tension in periodontal therapy.
- In cases where supra crestal fiberotomy is necessary to facilitate better tooth alignment.
- For patients with high relapse risk post-orthodontic treatment.
- When surgical intervention is required to manage periodontal attachment issues.
Documentation Requirements
- Detailed surgical report outlining the procedure.
- Pre- and post-operative photographs of the surgical site.
- Patient's consent form for the surgical procedure.
- Clinical notes documenting the necessity of the procedure.
- Orthodontic treatment plan if applicable.
- Post-operative care instructions provided to the patient.
Billing Considerations
When billing for D7291, ensure that the procedure is clearly documented and justified in the patient's records. This code may not be covered by all insurance plans, so verifying coverage beforehand is crucial. Frequency limitations may apply, especially in orthodontic cases. Common modifiers like -59 may be used to indicate distinct procedural services when performed in conjunction with other surgeries.
