Resin-Based Composite Posterior - CDT Code Guide
Overview
CDT code D2391 refers to a dental procedure involving the application of a resin-based composite to one surface of a posterior tooth. This procedure is typically performed to restore the function and appearance of a tooth that has been compromised by decay or damage. The use of resin-based composites is favored for their aesthetic qualities, as they can be closely matched to the natural color of teeth, providing a seamless restoration. This code is applicable not only for restorative purposes but also for preventive measures, as the wording has been adjusted to accommodate such uses. Dental professionals often use this procedure in cases where minimal decay is present or when a tooth requires reinforcement to prevent future decay.
When to Use This Code
- Restoring a posterior tooth with minimal decay on one surface
- Repairing a chipped or fractured posterior tooth
- Replacing an old or failing amalgam filling on a posterior tooth
- Preventive application to reinforce a weak area of a posterior tooth
- Aesthetic improvement of a discolored posterior tooth surface
Documentation Requirements
- Detailed chart notes describing the tooth surface treated
- Pre-operative and post-operative photographs if applicable
- Patient consent forms for the procedure
- Documentation of the materials used, including shade and type of composite
- Clinical justification for the use of a resin-based composite
Billing Considerations
When billing for D2391, it's important to note that insurance plans may have frequency limitations on how often this procedure can be performed on the same tooth. Common modifiers include those indicating the quadrant or specific tooth treated. Dental professionals should verify coverage with the patient's insurance provider, as some plans may have restrictions on composite restorations for posterior teeth.
