Onlay Metallic Two Surfaces - CDT Code Guide

Restorative/Inlay/Onlay Restorations

Overview

CDT Code D2542 refers to the placement of a metallic onlay covering two surfaces of a tooth. This restorative procedure is typically used when a tooth has sustained damage or decay that cannot be adequately repaired with a simple filling but does not require a full crown. The onlay is custom-made to fit the specific contours of the tooth and is bonded to the tooth to restore its function and appearance. This procedure is common in cases where the tooth structure needs reinforcement, and it provides a durable solution that can withstand the forces of chewing.

In clinical practice, a metallic onlay is often chosen for its strength and longevity, particularly in posterior teeth where the forces of mastication are greatest. The procedure involves preparing the tooth, taking an impression, and then fabricating the onlay, which is later cemented into place. Dental professionals should ensure that the tooth is adequately prepared and that the onlay fits precisely to prevent future complications.

When to Use This Code

  • When a tooth has moderate decay or fracture that involves two surfaces.
  • In cases where a simple filling is insufficient but a full crown is unnecessary.
  • For posterior teeth requiring additional strength and durability.
  • When the patient prefers a metallic restoration for its longevity.
  • To restore a tooth with existing large restorations that have failed.

Documentation Requirements

  • Detailed chart notes describing the tooth surfaces involved.
  • Pre-operative and post-operative radiographs to support the necessity of the onlay.
  • A narrative explaining why a full crown was not chosen.
  • Documentation of patient consent for the metallic material used.
  • Impression records or digital scans used for onlay fabrication.

Billing Considerations

When billing for D2542, ensure that the procedure is justified by the extent of the decay or damage. Insurance plans may have frequency limitations on restorative procedures, so verify patient benefits beforehand. Common modifiers include those indicating multiple procedures in the same visit. Be aware that some insurance plans may have specific coverage policies regarding metallic restorations versus other materials.
