Retainer Onlay Cast Noble Metal - CDT Code Guide
Overview
CDT code D6615 refers to a dental procedure involving the placement of a retainer onlay made from cast noble metal, covering three or more surfaces. This procedure is typically part of a fixed partial denture, serving as a retainer to support the dental prosthesis. It is commonly used when a tooth requires restoration and reinforcement due to extensive decay or damage, providing a durable and long-lasting solution. The use of noble metal ensures strength and biocompatibility, making it a preferred choice in many clinical scenarios.
When to Use This Code
- When a tooth requires restoration and reinforcement due to extensive decay or damage.
- In cases where a fixed partial denture needs a durable retainer.
- When the patient prefers a restoration with high strength and biocompatibility.
- For teeth that have undergone root canal treatment and need additional support.
- In situations where esthetic considerations are secondary to durability.
Documentation Requirements
- Detailed clinical notes describing the tooth condition and necessity for the onlay.
- Radiographic evidence supporting the need for the procedure.
- Documentation of patient consent and discussion of material options.
- Precise charting of the tooth surfaces involved.
- Laboratory prescription and material specifications.
- Post-operative notes detailing the fit and patient feedback.
Billing Considerations
When billing for D6615, ensure that the procedure is not performed more frequently than allowed by the patient's insurance plan. Common modifiers may include those for multiple restorations or complex cases. Verify coverage for noble metal restorations, as some plans may have specific exclusions or require pre-authorization.
