Insurance and Denial Prevention

Key Payer Rules:

• Surgical procedures may be covered under dental or medical insurance depending on the plan
• Impacted tooth extractions are often covered under both dental and medical plans
• Complex surgical procedures may require prior authorization
• Pathology-related procedures may be better covered under the medical benefit

Common Denials and How to Respond:

• Should be billed to medical - Some oral surgery codes are covered under medical rather than dental benefits. Check both plans.
• Not medically necessary - Submit operative notes, radiographs, and pathology reports to support the surgical indication.
• Complexity level disputed - Document the surgical approach, complications, and any bone removal or tooth sectioning performed.
