Send an EOB from the Primary Payer with the Claim

Secondary claim information goes in to loop 2320. We do not have any documentation on what is required for secondary claims since that is a billing-specific question. Also, if you want to send the EOB to the payer, work with the billing team to determine how you want those submitted. For more information about Billing or Invoice Assistance, check out the last page of the Support & Escalation Guide.
