How is secondary payer data captured on a UB-04 claim?

• A. Secondary payer information is included alongside primary payer data to support coordination of benefits.
• B. Secondary payer data replaces primary payer data when needed.
• C. There is no support for secondary payers on UB-04.
• D. Secondary payer data is only recorded on the claim if the service is inpatient.

Answer: (A)

Coordination of benefits is what this is about. On a UB-04 claim, secondary payer data is captured alongside the primary payer information so the claim can reflect more than one payer involved in a patient’s coverage. This setup lets the payer system determine responsibility in sequence—primary pays first, and the secondary payer can cover remaining amounts if the policy allows—without losing track of either payer’s details. It also supports benefit verification across multiple coverages for both inpatient and other institutional services. It isn’t about replacing the primary payer data, and the UB-04 does provide for secondary payer information beyond inpatient-only scenarios.
