Amalgam One Surface - CDT Code Guide
Overview
CDT Code D2140 pertains to the dental procedure involving an amalgam restoration on one surface of a primary or permanent tooth. This procedure includes the preparation of the tooth, application of all necessary adhesives, and the use of liners and bases as part of the restoration process. Amalgam, a durable and cost-effective material, is often used for restoring decayed areas of a tooth. This code is typically utilized in scenarios where a tooth has minor decay or damage that affects only one surface. It is important to note that if pins are used to secure the restoration, they must be reported separately under code D2951. This procedure is essential for maintaining tooth integrity and preventing further decay.
When to Use This Code
- When a patient presents with minor decay on one surface of a primary or permanent tooth.
- For restoring a chipped or worn surface of a tooth.
- In cases where a cost-effective restoration is preferred.
- When a durable restoration is needed for a posterior tooth.
- For patients with a history of amalgam restorations who require a similar repair.
Documentation Requirements
- Detailed chart notes describing the tooth surface treated.
- Documentation of the materials used, including adhesives and liners.
- Patient consent for the use of amalgam material.
- Radiographs or photographs showing the pre-operative condition of the tooth.
- Post-operative notes detailing the restoration process and outcome.
Billing Considerations
When billing for D2140, ensure that the procedure is not performed more frequently than allowed by the patient's insurance plan. Common modifiers may include those indicating the tooth number and surface. It's important to verify with the patient's insurance provider regarding coverage for amalgam restorations, as some plans may have restrictions or prefer alternative materials.
