A claim is denied for timely filing, but your system shows that it was originally submitted before the payer’s deadline. What evidence would you look for?

When a payer denies a claim for timely filing even though the billing system shows an earlier submission date, the key question is whether there is valid proof of timely submission and receipt.

The first step is to review the claim transmission history.

Useful evidence may include:

• Clearinghouse acceptance reports
• Payer acknowledgment reports
• Electronic submission logs
• Claim transmission batch reports
• Payer portal claim history
• Claim status inquiry records
• Internal billing system submission history
• Prior payer reference or claim numbers

A submission date in the billing system alone may not always be enough. The claim must generally have been transmitted successfully and accepted through the expected channel.

For example, if the claim was sent before the deadline but rejected by the clearinghouse because of invalid data, the payer may not consider that a valid timely filing submission.

That is why the rejection and acceptance history must be reviewed carefully.

I would also verify:

• Correct payer ID
• Correct insurance plan
• Correct patient and member information
• Date of service
• Original claim type
• Whether the claim was sent as primary or secondary
• Whether the payer actually received the claim
• Whether any corrected claim or resubmission occurred later

If the claim was submitted and accepted on time, I would gather the supporting documentation and follow the payer’s reconsideration or appeal process.

The supporting evidence should clearly show the original submission date and, when available, payer acceptance or receipt.

If the claim was originally sent to the wrong payer or rejected before reaching the correct payer, the timely filing denial may be valid unless the payer allows an exception.

The correct action depends on the payer’s rules, provider contract, and the quality of the available submission evidence.

A claim is denied for timely filing.

The billing system shows that it was submitted 45 days after the date of service, well within the payer’s filing limit.

The AR representative reviews the clearinghouse history and finds an acceptance report showing that the claim passed clearinghouse edits and was transmitted to the correct payer.

The payer portal also shows a claim reference number from that original submission.

The AR representative submits these records with a reconsideration request as proof that the claim was filed on time.
