Below are a few variables involved when it comes to dental insurance coverage and reimbursement:

• Most insurance plans will pay for a root canal once in a lifetime and deny payment for an apicoectomy.
• PPO plans may place a time limit from the time of completion of the root canal to when the apicoectomy has been performed.
• Submitting a clear written narrative explaining the reason for the apicoectomy to be performed and long term prognosis can help facilitate approval in most cases.
• If reporting a buildup or resin composite on the same tooth at the same visit, insurance plan will deny.
• Providing x-rays, narrative, recent periodontal charting, and photographs will ensure a smooth claim approval or denial and alleviate the need to submit additional information to the insurance company later.
