Retainer Inlay Porcelain/Ceramic - CDT Code Guide
Overview
CDT code D6600 pertains to the placement of a retainer inlay made from porcelain or ceramic, covering two surfaces. This procedure is part of fixed prosthodontics, specifically within the category of fixed partial denture retainers inlays/onlays. The inlay serves as a retainer to support a fixed partial denture, providing stability and function. Typically, this procedure is used when there is a need to restore the structural integrity of a tooth that supports a bridge, ensuring both aesthetic appeal and durability. Dental professionals often choose porcelain or ceramic materials for their natural appearance and strength, making them ideal for visible areas in the mouth.
When to Use This Code
- When a patient requires a fixed partial denture and the abutment tooth needs restoration.
- In cases where a tooth has moderate decay or damage affecting two surfaces and requires reinforcement.
- When replacing an existing retainer inlay that has failed or deteriorated.
- For patients with aesthetic concerns who prefer porcelain/ceramic materials for visible teeth.
- When a conservative restoration approach is preferred over a full crown.
Documentation Requirements
- Detailed clinical notes describing the tooth surfaces involved and the necessity for the inlay.
- Pre-operative and post-operative radiographs to support the treatment decision.
- Patient consent forms acknowledging the procedure and material choice.
- Documentation of the materials used, including the type of porcelain or ceramic.
- A comprehensive treatment plan outlining the role of the inlay in the overall prosthodontic solution.
Billing Considerations
When billing for D6600, ensure that the procedure is not performed more frequently than allowed by the patient's insurance plan. Common modifiers may include those indicating the quadrant or arch. Verify with the insurance provider regarding coverage for porcelain/ceramic materials, as some plans may have specific exclusions or limitations.
