Handling Coordination of Benefits in Open Dental

Insurance & Billing3 min read4/11/2026

When a patient has two insurance plans, managing the open dental coordination of benefits process is often where billing errors occur, leading to rejected secondary claims or incorrect patient balances. If you fail to link the primary payment correctly or neglect to set the secondary claim status to "Hold until Pri Received," you will likely end up with frustrated patients and unpaid claims that sit in your aging report indefinitely.

Before You Start

Before attempting to bill a secondary insurance plan, ensure the following prerequisites are met in your system:

  1. Verify Insurance Plans: Ensure both the primary and secondary insurance plans are entered correctly in the Family Module. The secondary plan must be listed below the primary plan in the "Insurance Plans" section.
  2. Verify Order of Benefits: Confirm that the "Order of Benefits" is set correctly for the patient. You can check this by double-clicking the insurance plan in the Family Module and ensuring the "Relationship to Subscriber" and "Coordination of Benefits" fields are accurate.
  3. Clear Primary Claim: The primary claim must be marked as "Received" in the Account Module before you can accurately bill the secondary carrier.

Step-by-Step Instructions

Follow these steps to process a secondary claim after the primary insurance has paid.

  1. Receive Primary Payment: Go to the Account Module. Locate the primary claim, double-click it to open the Edit Claim window, and click the "Receive Payment" button. Enter the payment details from the EOB or ERA.
  2. Create Secondary Claim: In the Account Module, click the dropdown arrow next to the "New Claim" button and select "Secondary Claim."
  3. Configure Secondary Claim: The Edit Claim window will open. Ensure the "Claim Type" is set to "Secondary."
  4. Set Status: On the Other Ins Info tab within the Edit Claim window, verify that the "Claim Status" is set to "Waiting to Send." If you are waiting for the primary EOB to be fully processed or attached, you may set the status to "Hold until Pri Received."
  5. Attach Primary EOB: If your clearinghouse requires the primary EOB for the secondary claim, use the "Attachments" section in the Edit Claim window to upload the primary EOB image.
  6. Submit Claim: Once the claim is ready, click "OK" to save. When you are ready to transmit, go to the Manage Module > "Send Claims" to batch and send the secondary claim to your clearinghouse.
