Retainer Onlay Cast Base Metal - CDT Code Guide

Prosthodontics, fixed/Fixed Partial Denture Retainers Inlays/Onlays

Overview

CDT Code D6612 refers to a retainer onlay that is cast from predominantly base metal and covers two surfaces. This procedure is part of fixed prosthodontics, specifically within the category of fixed partial denture retainers inlays/onlays. It involves creating a metal onlay that serves as a retainer for a fixed partial denture. This is typically used when a tooth requires additional support and coverage due to structural damage or decay, and when a more conservative approach than a full crown is desired. The base metal used in this procedure is chosen for its durability and cost-effectiveness, making it a practical choice for many patients.

When to Use This Code

  • When a tooth requires additional support for a fixed partial denture.
  • In cases where two surfaces of a tooth need restoration due to decay or damage.
  • When a more conservative approach than a full crown is preferred.
  • For patients who require a cost-effective solution using base metal.
  • When a durable restoration is needed for long-term stability.

Documentation Requirements

  • Detailed chart notes describing the tooth surfaces involved.
  • Pre-operative and post-operative radiographs.
  • Patient consent form acknowledging the use of base metal.
  • Documentation of the clinical necessity for a retainer onlay.
  • Material specifications and lab work orders.
  • Insurance pre-authorization, if required.

Billing Considerations

When billing for D6612, ensure that the procedure is documented thoroughly to justify the use of a retainer onlay. Be aware of any frequency limitations imposed by the patient's insurance plan. Common modifiers may include those indicating the specific tooth or quadrant. It's important to verify coverage for base metal materials, as some insurance plans may have restrictions or require additional documentation.
