Can D2630 be used for anterior teeth?

While technically possible, inlays are more commonly used for posterior teeth due to their ability to withstand chewing forces.

How long does a porcelain/ceramic inlay last?

With proper care, porcelain/ceramic inlays can last 10-15 years or more, depending on oral hygiene and habits.

Are there any specific patient conditions that contraindicate the use of inlays?

Inlays may not be suitable for teeth with extensive damage requiring a crown or for patients with severe bruxism without a protective night guard.

Is a temporary restoration needed before placing an inlay?

Yes, a temporary restoration is often placed while the custom inlay is being fabricated to protect the tooth.

Inlay Porcelain/Ceramic - CDT Code Guide

Restorative/Inlay/Onlay Restorations

Overview

CDT Code D2630 pertains to the placement of an inlay made from porcelain or ceramic materials, covering three or more surfaces of a tooth. This procedure is typically used when a tooth has sustained damage or decay that affects multiple surfaces, but the tooth structure is still strong enough to not require a full crown. Inlays are custom-made to fit the specific contours of the tooth, providing a durable and aesthetic restoration. This code is commonly used in restorative dentistry to restore function and appearance, particularly in molars and premolars where chewing forces are significant.

When to Use This Code

When a tooth has decay or damage affecting three or more surfaces.
When a patient prefers a more aesthetic and durable option than a direct filling.
In cases where the tooth structure is insufficient for a filling but does not require a full crown.
When replacing an old or failing restoration that covers multiple surfaces.
For patients with allergies to metal, requiring a non-metallic restoration.

Documentation Requirements

Detailed chart notes describing the extent of decay or damage.
Pre-operative radiographs showing the affected tooth surfaces.
Documentation of patient consent for the procedure.
Description of the materials used for the inlay.
Post-operative notes confirming the fit and function of the inlay.

Billing Considerations

When billing for D2630, ensure that the procedure is not performed more frequently than necessary, as insurance companies may have limitations on the frequency of inlay restorations. Common modifiers include those indicating the quadrant or arch. Verify with the patient's insurance for coverage specifics, as some plans may categorize inlays differently from crowns or fillings.
