Resin-Based Composite One Surface - CDT Code Guide

Preventive/Resin-Based Composite Restorations Direct

Overview

CDT Code D2391 refers to a dental procedure involving the restoration of a carious lesion or a deeply eroded area into the dentin using a resin-based composite material. This code is specifically used for posterior teeth and involves the application of composite material to one surface of the tooth. It is not a preventive procedure but rather a restorative one, aimed at repairing damage caused by decay or erosion. Dental professionals utilize this procedure to restore the tooth's function and aesthetics, ensuring the longevity of the tooth structure. Typical scenarios include treating cavities on molars or premolars where the decay has reached the dentin layer.

When to Use This Code

Restoring a single surface cavity on a posterior tooth
Repairing a deeply eroded area on a molar or premolar
Addressing decay that has penetrated into the dentin layer
Restoring function and aesthetics to a posterior tooth
When a direct resin-based composite restoration is clinically indicated

Documentation Requirements

Detailed clinical notes describing the carious lesion or erosion
Pre-operative and post-operative images if available
Documentation of the tooth number and surface treated
Description of the materials used in the restoration
Patient consent for the procedure
Notation of any complications or additional procedures performed

Billing Considerations

When billing for D2391, it is important to note that this code is specific to one surface of a posterior tooth. Frequency limitations may apply depending on the patient's insurance plan, and it is crucial to verify coverage prior to treatment. Common modifiers include those indicating the quadrant or specific tooth. Insurance companies may require pre-authorization for this procedure, especially if similar services have been billed recently.
