Billing Guide

Bill this code when:

• A prefabricated porcelain/ceramic crown - primary tooth is delivered and cemented on a prepared tooth
• The material and fabrication method match the code description
• The tooth preparation, impression, and delivery are documented

Do not bill this code when:

• The material or metal type does not match this code description
• The restoration is on an implant abutment rather than a natural tooth. Use the appropriate D6xxx implant crown code
• Only a temporary crown is placed. Use D2799 for a provisional crown
• 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.
