Amalgam Three Surfaces - CDT Code Guide
Overview
CDT Code D2160 refers to the dental procedure involving the restoration of a tooth with an amalgam filling covering three surfaces. This procedure is applicable to both primary and permanent teeth. During this process, the dentist prepares the tooth and applies all necessary adhesives, including amalgam bonding agents. Liners and bases are also included in the restoration process. This code is typically used when a tooth has decay or damage that affects three surfaces, requiring a durable and long-lasting restoration. Amalgam restorations are known for their strength and are often used in posterior teeth where the forces of chewing are greatest. It is important to note that if pins are used to retain the amalgam, they must be reported separately under code D2951.
When to Use This Code
- When a tooth has decay affecting three surfaces
- For restoring a primary tooth with significant surface damage
- In cases where a permanent tooth requires a strong, durable restoration
- When a patient prefers amalgam over composite for posterior teeth
- In situations where cost-effective restoration is needed
Documentation Requirements
- Detailed charting of the tooth surfaces involved
- Clinical notes describing the extent of decay or damage
- Documentation of patient consent for amalgam use
- Record of all materials used, including adhesives and liners
- Justification for the use of pins if applicable
- Pre- and post-operative images if available
Billing Considerations
When billing for D2160, it is important to consider the frequency limitations set by insurance providers, as some may restrict the number of restorations covered per year. Common modifiers may include those indicating the tooth number and surfaces treated. Additionally, insurance plans may have specific policies regarding the use of amalgam versus composite materials, so it's crucial to verify coverage details with the patient's insurer.
