How to appeal a Timely Filing denial

Why payers issue it

• The claim was sent on time but the payer has no record of it
• It bounced between primary and secondary payers (COB) and aged out
• A clearinghouse rejection wasn't caught and reworked in time
• The claim genuinely missed the window

What overturns it

• Submit proof of timely submission: clearinghouse acceptance reports, payer acknowledgment, or a screenshot of the original send
• For COB cases, show the primary payer's EOB date to reset the clock
• Invoke payer-specific exceptions (provider error vs payer error, retroactive eligibility)
• Document any system or eligibility issue outside your control

How do I appeal a Timely Filing denial?

A timely filing denial means the claim was received after the payer's filing deadline. It's the denial practices most often write off, and the one most often recoverable with proof. To overturn it: submit proof of timely submission: clearinghouse acceptance reports, payer acknowledgment, or a screenshot of the original send; for COB cases, show the primary payer's EOB date to reset the clock; invoke payer-specific exceptions (provider error vs payer error, retroactive eligibility); document any system or eligibility issue outside your control. The key is matching the documentation to the payer's own rule for timely filing denials.

Is a Timely Filing denial worth appealing?
