Core Buildup - CDT Code Guide
Overview
The CDT code D2950 refers to a core buildup procedure, which is essential when there is insufficient tooth structure to support a crown or other extracoronal restorative procedures. This procedure involves rebuilding the coronal structure of a tooth, often using materials like composite or amalgam, to provide adequate retention for the final restoration. It is important to note that a core buildup is not simply a filler for undercuts or irregularities in the tooth preparation; it serves a critical role in ensuring the stability and longevity of the final restoration. Dental professionals typically perform a core buildup when a tooth has been significantly compromised due to decay, fracture, or previous restorations, and requires additional support before placing a crown.
When to Use This Code
- When a tooth has extensive decay and lacks sufficient structure to support a crown.
- In cases where a tooth has fractured and needs reinforcement before a crown placement.
- When previous restorations have failed, and the tooth requires additional support.
- For teeth that have undergone endodontic treatment and need a stable foundation for a crown.
- When preparing a tooth for a bridge abutment that requires additional structural support.
Documentation Requirements
- Detailed clinical notes describing the need for a core buildup.
- Radiographic evidence supporting the lack of sufficient tooth structure.
- Documentation of the materials used for the buildup.
- Pre- and post-operative photographs, if applicable.
- Patient consent forms acknowledging understanding of the procedure.
- Insurance claim forms with accurate coding and descriptions.
Billing Considerations
When billing for D2950, it's important to note that some insurance plans may have frequency limitations on core buildups, often allowing one per tooth every few years. Additionally, modifiers may be necessary if the procedure is performed in conjunction with other restorative services. Always verify with the patient's insurance provider regarding coverage specifics and pre-authorization requirements.
