Managing an Open Dental Insurance Overpayment

Insurance & Billing3 min read3/29/2026

When an insurance carrier pays more than the expected amount for a procedure, it creates an open dental insurance overpayment that can throw off your patient balances and aging reports. If you simply ignore the extra funds or apply them incorrectly, your practice’s financial data becomes unreliable, making it difficult to reconcile your bank deposits or explain balances to patients.

Before You Start

Before addressing an overpayment, ensure your practice is running version 25.2 or 25.3 to utilize the most current payment reconciliation tools. You must have the original insurance payment already entered in the system. If you are receiving an ERA, ensure your clearinghouse is correctly configured to import these payments. Finally, verify that the patient’s insurance plan is correctly set up in the Family Module, as incorrect fee schedules are the most common cause of unexpected overpayments.

Step-by-Step Instructions

Follow these steps in the Account Module to correctly document and resolve the overpayment:

  1. Locate the Payment: In the Account Module, find the insurance payment line item that caused the overpayment. Double-click the payment to open the Edit Insurance Payment window.
  2. Verify the Allocation: Ensure the payment was applied correctly using the By Procedure button. If the payment was entered as a lump sum, you may need to adjust the individual procedure amounts to reflect the actual payment received.
  3. Create a Negative Adjustment: If the insurance company has requested a refund or if you need to reduce the patient's credit balance, go to the Account Module and click the Adj button.
  4. Configure the Adjustment: In the Edit Adjustment window, select an adjustment type specifically created for "Insurance Overpayment" or "Insurance Refund." Enter the overpayment amount as a negative number (e.g., -50.00).
  5. Attach to Provider: Ensure the adjustment is attached to the correct provider and date. Click OK to save.
  6. Handle the Refund: If you are sending a check back to the insurance company, create a manual check from your practice account. In Open Dental, use the Payment button in the Account Module to record a "negative payment" or a refund transaction to balance the account ledger.
