D2915Re-cement or Re-bond Cast or Prefabricated Post and Core

What This Code Covers

D2915 covers re-cement or re-bond cast or prefabricated post and core. A post provides retention within the root canal, and the core rebuilds the coronal structure to support a crown. This is billed in addition to the crown procedure code.

Billing Guide

Bill this code when:

• An existing restoration or appliance is re-cemented using D2915
• The device is intact and only needs to be re-attached
• Documentation confirms the device was previously placed and has loosened

Do not bill this code when:

• A new restoration or appliance is being placed for the first time
• The device is damaged and requires repair or replacement
• The re-cementation is within the payer's bundled period after initial placement
• The procedure is better described by D2910 (Re-cement or re-bond inlay, onlay, veneer or parti...)

Insurance and Denial Prevention

Key Payer Rules:

• Most plans cover restorative procedures at 50-80% depending on the specific service
• Downgrades may apply (e.g., porcelain crown downgraded to base metal on posterior teeth)
• Waiting periods often apply for major restorative services on new plans
• Some plans require prior authorization for crowns and indirect restorations

Common Denials and How to Respond:

• Material downgrade - The payer covers an alternate material at a lower fee. Bill the actual code and let the patient know about the potential balance.
• Waiting period not met - Verify the patient's plan effective date and any waiting periods for major services.
• Tooth not restorable - Submit radiographs and clinical documentation showing the tooth can be successfully restored.
