Insurance and Denial Prevention

Key Payer Rules:

• Endodontic treatment is typically covered at 50-80% as a major service
• Some payers require pre-operative radiographs for approval
• Retreatment codes have different fee schedules than initial treatment
• Surgical endodontic procedures may require prior authorization

Common Denials and How to Respond:

• Not medically necessary - Submit radiographs showing the pathology and document the diagnosis and treatment rationale.
• Should be extraction - Provide documentation of why the tooth is restorable and worth saving.
• Bundled with final root canal - If this is an interim procedure, document separate dates of service and the clinical reason for staged treatment.
