Insurance and Denial Prevention

Key Payer Rules:

• Fixed prosthodontic procedures are typically covered as major services
• Implant coverage varies widely by plan. Many plans exclude implants entirely
• Material downgrades may apply (high noble to base metal)
• Prior authorization is commonly required for implant and bridge procedures

Common Denials and How to Respond:

• Implants not covered - Check if the medical plan covers implants when the dental plan does not. Submit a detailed treatment narrative.
• Material downgrade - Bill the actual material placed and inform the patient of any balance due to plan downgrades.
• Missing tooth clause - Some plans exclude replacement of teeth that were missing before the plan effective date. Verify plan terms.
