Restorative Foundation - CDT Code Guide

Restorative/Other Restorative Services

Overview

CDT Code D2949 refers to the placement of a restorative foundation for an indirect restoration. This procedure involves using restorative material to create a more ideal tooth form, which includes the elimination of undercuts that could interfere with the placement of an indirect restoration such as a crown or bridge. This code is typically used when the existing tooth structure is insufficient to support an indirect restoration, necessitating the use of additional material to build up the tooth. Dental professionals often encounter this scenario in cases of significant tooth decay or fracture where the remaining tooth structure is compromised.

When to Use This Code

When preparing a tooth for a crown and the existing structure is inadequate.
In cases of significant decay where undercuts need to be eliminated for proper restoration fit.
When a tooth fracture has left insufficient structure for direct restoration.
During the preparation for a bridge where the abutment teeth require additional support.
In situations where previous restorations have failed and additional foundation is needed.

Documentation Requirements

Detailed chart notes describing the extent of tooth structure loss.
Pre-operative and post-operative images showing the necessity of the procedure.
Documentation of the materials used for the restorative foundation.
A clear description of the clinical rationale for choosing an indirect restoration.
Patient consent forms acknowledging the procedure and its purpose.

Billing Considerations

When billing for D2949, it's important to note that this code is often used in conjunction with codes for crowns or other indirect restorations. Be aware of any frequency limitations imposed by insurance carriers. Common modifiers may include those indicating the specific tooth treated. Ensure that the procedure is not billed as a separate restoration but as a foundation for an indirect restoration.
