Retainer Porcelain/Ceramic Crown - CDT Code Guide

Prosthodontics, fixed/Fixed Partial Denture Retainers Crowns

Overview

CDT code D6740 pertains to the placement of a retainer porcelain or ceramic crown as part of a fixed partial denture. This procedure involves the use of high-quality porcelain or ceramic materials to create a crown that serves as a retainer for a fixed bridge. It is typically employed in cases where one or more teeth are missing and a fixed partial denture is necessary to restore function and aesthetics. The crown is designed to fit over an existing tooth or implant abutment, providing support for the bridge. This code is crucial for dental professionals when planning restorative treatments that require durable and aesthetically pleasing materials.

When to Use This Code

When replacing a single missing tooth with a fixed bridge
In cases where aesthetics are a primary concern, and a porcelain/ceramic material is preferred
When a patient has a healthy abutment tooth that can support a fixed partial denture
For patients requiring a long-term solution for tooth loss
In scenarios where metal allergies necessitate the use of non-metallic materials

Documentation Requirements

Detailed patient history and diagnosis supporting the need for a fixed partial denture
Clinical notes describing the condition of the abutment teeth
Radiographic evidence showing the need for a retainer crown
Material specifications for the crown used
Detailed treatment plan outlining the procedure
Patient consent forms acknowledging understanding of the procedure

Billing Considerations

When billing for D6740, ensure that the procedure is not performed more frequently than necessary, as insurance companies may have limitations on the frequency of prosthodontic treatments. It's important to verify coverage with the patient's insurance provider, as some plans may have specific exclusions for porcelain or ceramic materials. Common modifiers may include those indicating the location of the crown or any special circumstances affecting the procedure.
