Guided Tissue Regeneration - CDT Code Guide
Overview
CDT Code D4267 refers to the guided tissue regeneration procedure using a non-resorbable barrier for natural teeth. This periodontal procedure is designed to regenerate lost periodontal structures, such as bone and the periodontal ligament, around natural teeth. It is particularly useful in treating periodontal defects that have not responded to non-surgical treatments. The procedure involves placing a barrier membrane to direct the growth of new bone and tissue, while excluding unwanted cell types from the healing site. This code specifically does not include flap entry and closure, wound debridement, osseous contouring, or bone grafting, which may be necessary in conjunction with this procedure depending on the clinical scenario.
When to Use This Code
- When there is a periodontal defect around a natural tooth that has not responded to scaling and root planing.
- In cases where there is sufficient bone remaining to support regeneration.
- When treating infrabony defects that are amenable to regenerative therapy.
- For patients with periodontal disease who are candidates for surgical intervention.
- In conjunction with other periodontal surgeries where regeneration is desired.
Documentation Requirements
- Detailed periodontal charting and diagnosis supporting the need for regeneration.
- Clinical notes describing the defect and rationale for using a non-resorbable barrier.
- Pre-operative and post-operative radiographs showing the defect and treatment outcome.
- Documentation of patient consent for the procedure.
- Description of the materials used, including the type of barrier membrane.
- Post-operative care instructions provided to the patient.
Billing Considerations
When billing for D4267, ensure that the procedure is not billed in conjunction with flap entry and closure or other procedures unless separately documented and justified. Check with insurance providers for coverage limitations, as some may require prior authorization. Common modifiers might include those indicating multiple sites or bilateral procedures. Frequency limitations may apply, so verify patient eligibility and benefits prior to treatment.
