Can a stress breaker be used in all fixed partial dentures?

No, stress breakers are specifically used when there is a need to manage differences in tooth mobility or protect weak abutment teeth.

How does a stress breaker differ from a rigid connector?

Unlike rigid connectors, stress breakers allow for slight movement between parts of the prosthesis, which helps in distributing forces more evenly.

Is pre-authorization required for billing D6940?

Pre-authorization may be required depending on the patient's insurance plan, so it's important to verify coverage beforehand.

What documentation is needed to justify the use of a stress breaker?

Documentation should include a detailed treatment plan, radiographic evidence, and notes on the condition of the abutment teeth.

Stress Breaker - CDT Code Guide

Prosthodontics, fixed/Other Fixed Partial Denture Services

Overview

CDT Code D6940 refers to a 'stress breaker,' which is a non-rigid connector used in fixed prosthodontics. This procedure involves the use of a device that allows for some movement between parts of a dental prosthesis, helping to distribute occlusal forces and reduce stress on the abutment teeth. Stress breakers are typically used in cases where there is a need to protect weak abutment teeth or when there is a significant difference in the mobility of the abutment teeth. By incorporating a non-rigid connector, the dental prosthesis can accommodate slight movements, which can be crucial for the longevity of the restoration and the health of the supporting structures.

When to Use This Code

When there is a significant difference in mobility between abutment teeth.
In cases where abutment teeth are weak and need protection from excessive forces.
When designing a fixed partial denture that spans a long edentulous area.
To prevent torque on abutment teeth in a fixed prosthesis.
In situations where stress distribution is critical to the success of the prosthesis.

Documentation Requirements

Detailed chart notes describing the need for a stress breaker.
Radiographic evidence supporting the choice of a non-rigid connector.
Comprehensive treatment plan outlining the prosthodontic design.
Patient consent form acknowledging understanding of the procedure.
Documentation of any pre-existing conditions affecting abutment teeth.

Billing Considerations

When billing for D6940, ensure that the use of a stress breaker is clearly justified in the patient's treatment plan. Be aware of any frequency limitations set by the patient's insurance provider. Common modifiers may include those indicating the specific location or complexity of the procedure. It's important to verify coverage with the insurance provider, as some may consider this procedure elective or require pre-authorization.
