How does coordination of benefits affect UB-04 submissions?

• A. It determines the payer order of payment and which fields must be populated for secondary payers.
• B. It has no effect on UB-04 submissions.
• C. It changes patient name on the claim.
• D. It determines facility location.

Answer: (A)

Coordination of benefits governs how to handle multiple insurances by setting the payer order and the data you must include for a secondary payer. On a UB-04 claim, you must identify which payer is primary and, if there is a secondary payer, fill in the fields for that secondary payer as well. The primary payer processes first and, depending on adjudication, may leave an unpaid amount that the secondary payer could cover. Because of this, the claim needs the primary payer’s details and the amount they paid, plus the secondary payer’s details and the amount they’re expected to pay, so the claim can be properly coordinated or cross-claimed. This helps prevent delays or denials due to missing or misordered payer information. Note that COB does not alter the patient’s name or the facility location; those elements are separate from payer sequencing and data.
