Retainer Onlay Cast High Noble Metal - CDT Code Guide
Overview
CDT code D6610 refers to a dental procedure involving the placement of a retainer onlay made from high noble metal, covering two surfaces of a tooth. This procedure is typically part of fixed prosthodontics, specifically for fixed partial denture retainers. It involves casting a high noble metal onlay that serves as a retainer to support a bridge or other prosthetic device. This is often used when a tooth requires additional support due to structural compromise or to replace missing teeth in a fixed partial denture scenario. The use of high noble metal ensures durability and biocompatibility, making it a preferred choice for long-term dental restorations.
When to Use This Code
- When a tooth requires additional support for a fixed partial denture.
- In cases where a high noble metal is preferred for its durability and biocompatibility.
- When two surfaces of a tooth need coverage to provide adequate retention.
- For patients with a history of metal allergies, ensuring the use of high noble metals.
- In scenarios where a cast onlay is necessary to restore function and aesthetics.
Documentation Requirements
- Detailed chart notes describing the tooth surfaces involved.
- Pre-operative and post-operative radiographs.
- Documentation of the material used, specifying high noble metal.
- Patient consent forms acknowledging the procedure and material choice.
- Clinical notes on the necessity of the onlay for retention purposes.
Billing Considerations
When billing for D6610, ensure that the procedure is not performed more frequently than necessary, as insurance may have limitations on the frequency of prosthodontic procedures. Common modifiers include those indicating the quadrant or arch. Verify with the patient's insurance for coverage on high noble metal restorations, as some plans may have specific material restrictions.
