Additional Prefabricated Post - CDT Code Guide

Restorative/Other Restorative Services

Overview

CDT code D2957 is used for billing each additional prefabricated post placed in the same tooth, following the initial post placement coded under D2954. This procedure is typically necessary when a tooth requires additional support due to extensive structural damage or decay. Prefabricated posts are used to reinforce the tooth structure before placing a crown, ensuring stability and longevity of the restoration. Dental professionals often encounter this scenario in teeth that have undergone root canal therapy and need additional reinforcement to support the final restoration. The use of multiple posts can help distribute stress and prevent fracture of the remaining tooth structure.

When to Use This Code

When a tooth requires additional support after the initial prefabricated post (D2954) has been placed.
In cases where the tooth structure is severely compromised and cannot support a crown with a single post.
For teeth that have undergone root canal therapy and need multiple posts for adequate reinforcement.
When restoring a tooth with significant coronal loss requiring multiple posts for stability.
In situations where the initial post does not provide sufficient retention for the planned restoration.

Documentation Requirements

Detailed clinical notes indicating the need for additional posts.
Radiographic evidence supporting the placement of multiple posts.
Documentation of the tooth number and the specific location of each post.
A description of the condition of the tooth and justification for additional support.
Verification of the initial post placement under code D2954.
Patient consent for the procedure, noting the use of multiple posts.

Billing Considerations

When billing for D2957, ensure that the initial post is billed under D2954. This code is used for each additional post on the same tooth, and it is important to document the necessity clearly. Be aware of any frequency limitations set by insurance providers, and consider using appropriate modifiers if required. Always verify with the patient's insurance for coverage specifics, as some plans may have restrictions on the number of posts covered per tooth.
