Guided Tissue Regeneration - CDT Code Guide
Overview
CDT code D4266 refers to the procedure of guided tissue regeneration using a resorbable barrier, specifically for natural teeth. This technique is crucial in periodontal therapy, aimed at regenerating lost periodontal structures due to disease. The procedure involves placing a resorbable barrier to direct the growth of new bone and tissue, facilitating the regeneration of periodontal defects around natural teeth. It is important to note that this code does not cover flap entry and closure or additional procedures such as wound debridement or bone grafting, which may be necessary depending on the clinical situation. Dental professionals often use this code in cases where periodontal disease has resulted in significant tissue loss, and regeneration is needed to restore function and aesthetics.
When to Use This Code
- When treating periodontal defects around natural teeth requiring regeneration
- In cases where a resorbable barrier is preferred over non-resorbable options
- For patients with periodontal disease leading to significant tissue loss
- When aiming to regenerate periodontal structures without additional osseous grafting
- In conjunction with other periodontal therapies to enhance treatment outcomes
Documentation Requirements
- Detailed periodontal charting and diagnosis
- Clinical notes on the necessity of guided tissue regeneration
- Documentation of the specific site(s) treated
- Description of the resorbable barrier material used
- Pre- and post-operative radiographs if applicable
- Patient consent and understanding of the procedure
Billing Considerations
When billing for D4266, it is important to ensure that the procedure is not bundled with other periodontal surgeries unless specified by the insurance provider. Frequency limitations may apply, and it is crucial to verify patient benefits and coverage for periodontal regeneration procedures. Common modifiers such as -51 (multiple procedures) may be used if applicable. Always check with the patient's insurance for specific guidelines and pre-authorization requirements.
