How long does a metallic onlay last?

With proper care, a metallic onlay can last many years, often exceeding 10-15 years, depending on the patient's oral hygiene and habits.

Is a metallic onlay better than a crown?

A metallic onlay is less invasive than a crown and is suitable when the tooth structure is sufficient to support it. Crowns are used when more extensive coverage is needed.

Can a metallic onlay be used on any tooth?

Metallic onlays are typically used on molars and premolars where the strength of the material is most beneficial.

Are there aesthetic concerns with metallic onlays?

Yes, metallic onlays are visible and may not be preferred for front teeth due to aesthetic reasons. Patients should be informed about the appearance before proceeding.

Onlay Metallic Four Surfaces - CDT Code Guide

Restorative/Inlay/Onlay Restorations

Overview

CDT code D2544 refers to a restorative dental procedure involving the placement of a metallic onlay covering four or more surfaces of a tooth. This procedure is typically used when a tooth has extensive decay or damage that cannot be adequately restored with a simple filling but does not require a full crown. The metallic onlay is custom-made to fit the specific contours of the tooth, providing a durable and long-lasting restoration. This code is commonly used in scenarios where the structural integrity of the tooth needs reinforcement, and the patient desires a strong, metal-based restoration.

When to Use This Code

When a tooth has significant decay affecting four or more surfaces.
In cases where a tooth has been fractured and requires substantial restoration.
When previous restorations have failed, and a more durable solution is needed.
For patients who prefer a metal restoration for its strength and longevity.
When a tooth requires reinforcement but a full crown is not necessary.

Documentation Requirements

Detailed chart notes describing the extent of the decay or damage.
Pre-operative and post-operative radiographs showing the tooth condition.
Documentation of the patient's consent for the metallic onlay procedure.
A description of the materials used and the surfaces covered by the onlay.
A record of the patient's dental history and previous restorations.

Billing Considerations

When billing for D2544, it's important to note that insurance coverage may vary, and some plans may have frequency limitations on restorative procedures. Common modifiers such as 'U' for upper arch or 'L' for lower arch may be used. Ensure that the procedure is justified with appropriate documentation to avoid claim denials.
