Retainer Crown Full Cast - CDT Code Guide
Overview
CDT Code D6791 refers to a retainer crown that is full cast and predominantly made of base metal. This procedure is part of fixed prosthodontics and involves the creation and placement of a crown that serves as a retainer for a fixed partial denture. The crown is fabricated using base metals, which are durable and cost-effective materials. This procedure is typically indicated when a patient requires a fixed partial denture to replace missing teeth, and the abutment teeth need reinforcement with a crown. The full cast predominantly base metal crown offers strength and stability, making it suitable for posterior teeth where aesthetic concerns are less critical.
When to Use This Code
- When a patient requires a fixed partial denture and the abutment tooth needs reinforcement.
- In cases where the abutment tooth is structurally compromised and requires a durable crown.
- When cost-effectiveness is a priority, and the aesthetic demands are minimal.
- For posterior teeth where strength and durability are paramount.
- When a patient has a history of metal allergies, and base metals are deemed safe.
Documentation Requirements
- Detailed patient chart notes indicating the need for a fixed partial denture.
- Pre-operative radiographs showing the condition of the abutment tooth.
- Material specifications for the crown, highlighting the use of base metals.
- Documentation of patient consent for the procedure and material used.
- Post-operative notes detailing the fit and function of the crown.
- Insurance pre-authorization, if required, for the use of base metal materials.
Billing Considerations
When billing for D6791, 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. It's important to verify coverage for base metal crowns, as some insurance plans may have restrictions or require pre-authorization. Coordination with the lab for material costs is also crucial to ensure accurate billing.
