Your medical claim keeps getting denied as “timely filing” after the Change Healthcare outage: how to resubmit, appeal, and get paid in 2026

Try this
A common 2025–2026 headache is getting old medical claims denied for “timely filing” (submitted too late), even when the delay traces back to the February 2024 Change Healthcare cyberattack and its long recovery. The fix is usually not one magical phone call—it’s building a simple paper trail (proof of the disruption), resubmitting correctly, and escalating with the right documentation. This guide gives a practical, step-by-step playbook for patients and providers to reverse timely-filing denials and reduce the chance they happen again.

Your medical claim keeps getting denied as “timely filing” after the Change Healthcare outage (2026 fix guide)

The problem (and who it hits)

If you’ve seen one of these messages, you’re not alone:
  • EOB/ERA says: “Denied—timely filing,” “claim filed after time limit,” or similar.
  • Provider says: “We billed, but insurance won’t pay because it’s late.”
  • Patient experience: You get a bill months later (sometimes a surprise balance) because the insurer rejected the claim.

This has been especially common since the Change Healthcare cyberattack (February 2024) disrupted claims, eligibility checks, payments, and other core healthcare transactions nationwide. The American Hospital Association (AHA) reported broad operational and financial impact across hospitals, and many organizations used manual workarounds for weeks/months. Even after systems came back, backlogs and downstream processing delays continued for some providers—creating a perfect setup for late submissions and denials. [1] [2]

Why it’s happening (what changed)

Three overlapping realities are driving this:

1. A massive clearinghouse outage created delayed or “stuck” claims. Change Healthcare is a major transaction hub; the disruption affected claims processing and payment workflows across the U.S. healthcare system. [1] [3]

2. Insurers’ timely-filing rules didn’t automatically pause everywhere. Many payers have filing windows (often measured in days from date of service). When providers couldn’t transmit claims normally (or had to rework batches later), some claims crossed those deadlines.

3. The fallout persisted long after the initial outage. Physician groups and associations reported that timely-filing denials continued more than a year after the incident, even with guidance urging flexibility. [4]

Separately, the incident was enabled by basic security failures—U.S. and major media reporting indicated attackers used compromised credentials and accessed a Citrix portal that lacked multifactor authentication—underscoring why the disruption was so severe and prolonged. [5]

Solutions: what to do (step-by-step)

Solution A (providers): Build a “timely filing exception” packet and resubmit

Goal: Get the payer to treat the claim as on-time (or grant an exception) due to the documented disruption.

1) Identify exactly what the payer wants


  • Pull the denial: note payer, claim number, CPT/HCPCS, DOS, denial code, and the timely filing limit referenced.

  • Check whether the payer has a specific reconsideration form or portal flow.

2) Assemble proof the delay was disruption-related (keep it simple)
Include 2–5 items max:


  • A short cover letter: “Request timely filing exception due to Change Healthcare outage-related transmission disruption.”

  • Clearinghouse evidence: rejection reports, queued batches, outage notices, screenshots, ticket numbers.

  • Internal log: when the claim was created, held, retransmitted.

3) Resubmit the clean claim correctly


  • Use the payer’s preferred channel (EDI, portal, paper—whatever they require for reconsiderations).

  • Make sure provider NPI, taxonomy, payer ID, subscriber ID, and place of service match exactly.

4) Send it to the right place and track it


  • If paper: certified mail or trackable shipping.

  • If portal: save the submission confirmation.

  • Set a follow-up date (e.g., 14 business days) and call with the exact reference.

5) If denied again: escalate to a formal appeal


  • Ask the payer rep: “Is this eligible for appeal vs reconsideration?”

  • Attach the earlier packet plus the new denial.

Solution B (patients): Stop a “late claim” from becoming your bill

Patients usually can’t fix EDI timing—but you can prevent a denial from turning into collections.

1) Ask the provider for two things in writing


  • A copy of the insurer denial/EOB showing timely filing.

  • A statement that they will appeal/rebill and will pause patient billing during the appeal.

2) Call the insurer and open a case
Use a script:


  • “This was denied for timely filing. The provider indicates the delay relates to the Change Healthcare outage. I’m requesting a review and guidance for resubmission/appeal.”


Get: case number + mailing/fax address + required wording.

3) Request a billing hold with the provider’s billing office


  • Ask for a 90-day hold (or their standard appeal hold).

  • If you already received a collection notice, request a pause while the dispute is active.

4) If you’re stuck: file a complaint with your state regulator


  • For fully insured plans: your state’s Department of Insurance can often help.

  • For some employer self-funded plans, escalation may be through the plan administrator; ask the insurer which it is.

Solution C (small practices): Reduce future timely-filing risk (low-cost)

1) Add a weekly “timely filing clock” report
  • Sort unsubmitted claims by date of service.
  • Flag anything approaching the payer limit.

2) Maintain dual submission paths


  • If your main clearinghouse is down, have a documented backup: payer portals for top payers, paper for the rest.

3) Keep outage documentation templates ready


  • A one-page letter template + a folder for screenshots/tickets.

4) Confirm your clearinghouse/payer connectivity is truly restored


  • Don’t assume “system is up” equals “your submitter ID is flowing.” Do test claims and verify acknowledgments.

Checklist (copy/paste)

  • [ ] Denial code confirms timely filing (not eligibility, coverage, or missing info)
  • [ ] Claim number + DOS + payer timely-filing limit recorded
  • [ ] Exception packet prepared (cover letter + proof + claim copy)
  • [ ] Resubmitted via payer-required channel
  • [ ] Tracking saved (portal confirmation / certified mail receipt)
  • [ ] Follow-up date scheduled
  • [ ] If patient: provider billing hold requested + insurer case number obtained

FAQ

1) What does “timely filing” actually mean?
It’s the insurer’s rule for how long after the date of service a claim must be received to be eligible for payment. If they treat it as “received late,” they deny—even if the service was covered.

2) Will the payer automatically waive timely filing because of the Change Healthcare incident?
Not always. Many situations require a specific reconsideration/appeal with documentation showing the delay was disruption-related. [4]

3) I’m the patient—can I appeal this myself?
You can open a case and submit an appeal for coverage decisions, but timely filing is often processed on the provider claim side. Your best leverage is (a) a documented request that the provider appeal and (b) an insurer case that notes the issue.

4) What evidence is most convincing?
Clearinghouse rejection/hold reports, dated screenshots, and tickets tied to the impacted period. Pair those with a short, clear cover letter.

5) How big was the Change Healthcare incident, really?
HHS’ Change Healthcare incident FAQ notes that Change reported to OCR that about 192.7 million individuals were impacted (reported July 31, 2025). [6]

Key Takeaways

  • Timely-filing denials are often reversible when you document the disruption and follow the payer’s reconsideration/appeal process.
  • Use a tight exception packet: cover letter + proof + clean claim.
  • Patients should focus on billing holds, insurer case numbers, and preventing collections while the provider appeals.
  • Build a lightweight weekly workflow so claims don’t age past payer limits.
