When a claim is sent as a paper claim, the claim is submitted to the clearinghouse and goes through the same claim-scrubbing processes as electronically-submitted claims.
The claim is then sent to an intermediary that prints and mails the claim to the payer. The delivery date of the claim from the Intermediary to the payer will follow standard USPS mail services.
To ensure that a claim has made it to the Intermediary, you can check the Processing Events tab after clicking into any claim ID. The status of the claim will be "Claim to be Printed and Mailed" when this process is complete. We advise waiting 5-7 business days before calling the payer to confirm receipt of the claim.
