When handling claims with more than one payer on CMS-1500, what is the correct submission order?

• A. Submit to both payers simultaneously.
• B. Submit only to the payer that pays the majority of the claim.
• C. Submit to the primary payer first, then the secondary with any required COB information and EOBs.
• D. Submit to the secondary payer first.

Answer: (C)

Coordinating benefits is the key idea here. When more than one payer could cover a claim, you must determine which payer is primary and which is secondary, then submit the claim in that order. The correct approach is to send the claim to the primary payer first. After the primary payer processes the claim, you submit to the secondary payer, supplying any required coordination of benefits information and the primary payer’s EOB. The secondary uses the primary EOB to determine what the secondary should pay, what the patient still owes, and how to coordinate benefits so there’s no duplicate or inappropriate payment. Submitting to both at the same time isn’t the standard workflow because the secondary relies on the outcome and details from the primary (via the EOB and COB data) to adjudicate correctly. Submitting to the secondary first or choosing a different payer as primary doesn’t follow the COB rules and can lead to delays or incorrect payments.
