837P Claim from Payer A to Payer B (Coordination of Benefits)

This is an example of how coordination of benefits between multiple payers could be implemented.

Payer A will pass the claim directly to Payer B without intervention from provider.

If this claim were to go from the Billing Provider to Payer A and then Payer A were to send it claim directly to Payer B, the transaction would look like this as it comes out of Payer A’s processing system. In this situation, the Billing Provider must send Payer A all the COB information on Payer B.

This is an example of an EDI transaction provided by X12. Both the EDI string and the explanation are available here.
