Handling an Open Dental Insurance Overpayment

Insurance & Billing4 min read3/31/2026

When an insurance carrier pays more than the expected amount for a procedure, it creates an open dental insurance overpayment that can quickly clutter your patient ledgers. If you simply leave the extra money sitting on the claim, your production and collection reports will be inaccurate, and you may struggle to determine if the money belongs to the patient or needs to be refunded to the insurance company.

Before You Start

Before addressing an overpayment, ensure your practice is using version 25.2 or 25.3 to take advantage of the latest payment handling features. You should have the original EOB or ERA in front of you to verify the payment details. Ensure that the insurance plan is correctly set up in the Family Module and that the claim status is currently marked as "Received." If you are working with electronic payments, confirm that your clearinghouse integration is functioning correctly so that the payment amounts match your bank deposits.

Step-by-Step Instructions

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

  1. Locate the Claim: In the Account Module, find the claim that resulted in the overpayment. Double-click the claim to open the Edit Claim window.
  2. Verify Payment: Ensure the payment has been entered correctly. If you need to adjust the payment amount, click the "Supplemental" button if you are adding to an existing payment, or edit the existing payment line item if the total amount received was entered incorrectly.
  3. Identify the Overpayment: If the insurance paid more than the allowed amount for a procedure, you will see a negative balance on that specific procedure line.
  4. Handle the Credit:
    • If the overpayment is a mistake by the insurance company and they request a refund, you must create a negative payment entry to offset the ledger.
    • In the Account Module, click the "New Payment" button.
    • Select the insurance carrier as the "Payor."
    • Enter the amount as a negative number (e.g., -50.00).
    • In the "Note" field, clearly document that this is a "Refund to Insurance for Overpayment" and include the check or ERA reference number.
  5. Finalize: Click "OK" to save the payment. The patient's account balance will now reflect the corrected amount, and the insurance ledger will be balanced.
