Connector Bar - CDT Code Guide

Prosthodontics, fixed/Other Fixed Partial Denture Services

Overview

CDT code D6920 refers to the use of a connector bar, an essential component in prosthodontics for stabilizing and anchoring removable overdenture prostheses. This device is attached to a fixed partial denture retainer or coping, providing a secure foundation for removable dentures. Typically, a connector bar is used in cases where patients require additional support for their dentures due to insufficient natural tooth structure or bone support. By distributing the forces evenly across the dental arch, the connector bar enhances the comfort and functionality of the overdenture, improving the patient's ability to chew and speak effectively.

When to Use This Code

  • When a patient requires stabilization for a removable overdenture due to insufficient natural tooth support.
  • In cases where a fixed partial denture is already in place and needs to support an overdenture.
  • For patients with significant bone loss where additional support for dentures is necessary.
  • When enhancing the retention and stability of an overdenture is needed.
  • In complex prosthodontic cases requiring a combination of fixed and removable prostheses.

Documentation Requirements

  • Detailed patient history and diagnosis supporting the need for a connector bar.
  • Clinical notes describing the existing fixed partial denture and the need for additional support.
  • Radiographic evidence showing the dental arch and existing prosthetic structures.
  • A treatment plan outlining the procedure and expected outcomes.
  • Patient consent forms and documentation of discussions regarding treatment options.

Billing Considerations

When billing for D6920, ensure that the procedure is not performed more frequently than necessary, as overuse may not be covered by insurance. Common modifiers may include those indicating the specific quadrant or arch involved. It's important to verify with the patient's insurance provider regarding coverage for prosthodontic services, as policies can vary significantly.
