Billing Guide

Insurance and Denial Prevention

Key Payer Rules:

• Orthodontic benefits are typically separate from standard dental benefits with a lifetime maximum
• Many plans require documentation of medical necessity (handicapping malocclusion)
• Age limits may apply (some plans only cover patients under 19)
• Payment is often spread over the course of treatment

Common Denials and How to Respond:

• Not medically necessary (cosmetic) - Document the functional impairment caused by the malocclusion and submit diagnostic records.
• Lifetime maximum reached - Verify the patient's remaining orthodontic benefit and discuss payment options for any balance.
• Age limit exceeded - Some plans cover adult orthodontics. Verify plan terms and appeal if appropriate.
