Prefabricated Post and Core - CDT Code Guide
Overview
CDT code D2954 refers to the procedure of placing a prefabricated post and core in addition to a crown. This restorative service is essential when a tooth has undergone root canal therapy and lacks sufficient tooth structure to support a crown. The procedure involves inserting a prefabricated post into the root canal, around which a core is built to provide a stable foundation for the crown. This code is commonly used in restorative dentistry to ensure the longevity and stability of the crown restoration, especially in cases where the tooth structure is significantly compromised.
When to Use This Code
- When a tooth has undergone root canal treatment and lacks sufficient structure for a crown.
- In cases where there is significant tooth structure loss due to decay or fracture.
- When reinforcing a tooth that has been previously restored and needs additional support.
- For teeth that require a crown but have minimal remaining natural tooth structure.
- In situations where a prefabricated post is more suitable than a custom cast post.
Documentation Requirements
- Detailed clinical notes describing the need for a post and core.
- Radiographic evidence supporting the lack of tooth structure.
- Documentation of the materials used for the post and core.
- Patient's consent form acknowledging understanding of the procedure.
- Pre- and post-operative images if applicable.
- Notation of any complications or additional procedures performed.
Billing Considerations
When billing for D2954, it's important to note that this code is used in conjunction with a crown code. Ensure that the post and core are necessary and not included in the crown fee. Frequency limitations may apply, so verify with the patient's insurance. Common modifiers include those indicating the quadrant or arch. Always check for specific insurance guidelines regarding coverage for post and core procedures.
