Connective Tissue Graft - CDT Code Guide
Overview
The D4273 code refers to the autogenous connective tissue graft procedure, a periodontal surgical service. This procedure involves two surgical sites: a recipient site and a donor site. At the recipient site, a split thickness incision is made to retain a flap of gingiva or mucosa. The connective tissue is then harvested from a donor site, typically the palate, leaving an epithelialized flap for closure. This procedure is commonly used to treat gingival recession, improve aesthetics, or enhance the thickness of the gingiva around teeth or implants. It is essential for maintaining periodontal health and can be a crucial part of comprehensive periodontal therapy.
When to Use This Code
- To address gingival recession and root exposure
- To increase the thickness of gingiva around dental implants
- For aesthetic improvement in areas with thin gingival biotype
- To cover exposed root surfaces in teeth with recession
- When preparing a site for future restorative or orthodontic treatment
Documentation Requirements
- Detailed clinical notes describing the recipient and donor sites
- Pre-operative and post-operative photographs
- Patient consent forms for surgical procedures
- Documentation of the patient's periodontal condition and treatment plan
- Post-operative care instructions provided to the patient
Billing Considerations
When billing for D4273, it is important to note that this procedure is typically covered once per site per lifetime by most insurance plans. Modifiers may be necessary if the procedure is performed in conjunction with other periodontal surgeries. Verify with the patient's insurance for specific coverage details and any pre-authorization requirements.
