Overdenture Partial Mandibular - CDT Code Guide

Prosthodontics, removable/Other Removable Prosthetic Services

Overview

CDT code D5866 refers to the procedure of creating and fitting an overdenture partial for the mandibular arch. This procedure is part of the removable prosthodontics category and involves designing a partial denture that fits over existing teeth or implants in the lower jaw. It is typically used in cases where patients have lost several teeth but still retain some natural teeth or implants that can support a partial denture. The overdenture helps in restoring function and aesthetics, improving chewing ability, and maintaining the structure of the jawbone by distributing the forces evenly across the dental arch.

When to Use This Code

When a patient has multiple missing teeth in the mandibular arch but retains some natural teeth or implants.
For patients who require improved stability and retention of their dentures.
In cases where preserving the remaining natural teeth is essential for maintaining jawbone structure.
When a patient desires a removable prosthetic option that offers enhanced comfort and functionality.
For patients with compromised oral health who need a conservative approach to tooth replacement.

Documentation Requirements

Detailed patient dental history and current oral health status.
Clinical notes on the condition of the remaining teeth or implants in the mandibular arch.
Radiographic evidence supporting the need for an overdenture.
A treatment plan outlining the design and materials used for the overdenture.
Patient consent forms and documentation of discussions regarding treatment options.
Records of any adjustments or follow-up appointments related to the overdenture.

Billing Considerations

When billing for D5866, it's important to consider the frequency limitations set by insurance providers, as some may only cover this procedure once every few years. Common modifiers may include those indicating the arch treated or adjustments made. Ensure that the patient's insurance plan covers removable prosthetics, as coverage can vary significantly.
