Onlay Resin-Based Composite - CDT Code Guide
Overview
CDT code D2663 refers to the placement of an onlay made from resin-based composite material covering three surfaces of a tooth. This procedure is typically used when a tooth is too damaged for a simple filling but does not require a full crown. The onlay helps restore the tooth’s function and appearance, providing a durable and aesthetic solution. Dental professionals often choose this procedure for patients with moderate decay or fractures that compromise multiple surfaces of a tooth. The resin-based composite material offers a natural look and is bonded to the tooth structure, enhancing strength and longevity.
When to Use This Code
- When a tooth has moderate decay affecting three surfaces
- For a fractured tooth that does not require a full crown
- In cases where aesthetics are important and a natural look is desired
- When a patient prefers a less invasive option compared to a crown
- To restore function and prevent further decay in a compromised tooth
Documentation Requirements
- Detailed chart notes describing the tooth surfaces involved
- Pre-operative and post-operative radiographs
- Patient consent forms for the procedure
- Documentation of the materials used
- Clinical justification for choosing an onlay over other restorations
Billing Considerations
Ensure the onlay is not billed more frequently than allowed by the patient's insurance plan. Be aware of any specific insurance policies regarding composite materials. Common modifiers may include those indicating multiple restorations on the same tooth. Verify coverage for resin-based materials, as some plans may have restrictions.
