Guided Tissue Regeneration - CDT Code Guide
Overview
CDT code D7957 refers to the guided tissue regeneration procedure using a non-resorbable barrier in edentulous areas. This surgical procedure is often employed to regenerate bone and soft tissue in areas where teeth are missing, enhancing the foundation for future dental restorations or implants. It is particularly useful in cases of ridge augmentation, sinus lift procedures, and post-tooth extraction healing. The process involves placing a barrier membrane to direct the growth of new bone and tissue, ensuring that the regenerated area is suitable for further dental work. This code specifically excludes flap entry and closure, wound debridement, osseous contouring, and the use of bone grafts or biologic materials.
When to Use This Code
- Ridge augmentation in preparation for dental implants
- Sinus lift procedures to facilitate implant placement
- Post-extraction site preparation for future prosthetics
- Cases requiring enhanced bone regeneration in edentulous areas
- When a non-resorbable barrier is preferred over a resorbable one
Documentation Requirements
- Detailed clinical notes describing the edentulous site
- Pre-operative and post-operative radiographs
- Description of the barrier material used
- Surgical notes excluding flap entry and closure
- Patient consent forms for the procedure
- Documentation of any complications or additional procedures
Billing Considerations
When billing for D7957, ensure that the procedure is not bundled with other surgeries such as flap entry or osseous contouring. Check for frequency limitations as some insurance plans may restrict the number of times this procedure can be performed. Common modifiers include those indicating separate procedures or bilateral sites. Verify with the patient's insurance for coverage specifics, as some plans may require pre-authorization.
