The Cigna timely filing limit requires participating providers to submit claims within 90 days of the date of service, and out-of-network providers within 180 days. Miss the deadline and Cigna denies the claim with adjustment code CO-29, a balance the provider’s contract prohibits billing to the patient. Getting claims out the door inside this window is one of the simplest ways to protect revenue, which is why claims submission and processing speed matters as much as accuracy.
What Is Cigna’s Timely Filing Limit for In-Network Providers?
Participating (in-network) providers must submit claims within 90 days, or three months, of the date of service.
What Is Cigna’s Timely Filing Limit for Out-of-Network Providers?
Out-of-network providers have 180 days, or six months, from the date of service to submit a claim.
What Is Cigna’s Deadline for Corrected Claims?
The original filing deadline generally still applies to a corrected claim, unless Cigna specifically requested additional information, in which case a different timeframe may apply.
What Is Cigna’s Appeal Deadline?
Providers have 180 calendar days from the date of the initial payment or denial decision to file an appeal.
Key Takeaways
- The Cigna timely filing limit is 90 days from the date of service for participating providers and 180 days for out-of-network providers.
- For consecutive-day services, such as a hospital confinement, the clock starts from the last date of service, not the first.
- Appeals must be filed within 180 calendar days of the initial payment or denial decision.
- A missed deadline results in a CO-29 denial, which the provider’s contract prohibits billing to the patient.
- Exceptions exist for coordination-of-benefits claims, applicable law, and specific provider agreement terms.
- Non-participating providers billing Cigna Healthcare for Seniors get a much longer window, 15 to 27 months, under Medicare processing rules.
What Counts as the Start of Cigna’s Filing Clock?
The clock starts on the date of service for a single visit. For services rendered on consecutive days, such as an inpatient hospital confinement, the deadline is counted from the last date of service in that stay, not the first. This distinction matters most in hospitalist billing, where multi-day stays are the norm rather than the exception.
What Happens If a Claim Is Filed Late?
Cigna returns the claim with adjustment code CO-29, the time limit for filing has expired. Because this is a contractual obligation denial, the provider’s agreement with Cigna prohibits balance-billing the patient for it, making a late claim a pure write-off.
What Are the Key Things to Know About the Cigna Timely Filing Limit?
The ten points below cover the deadlines, exceptions, and resolution paths specific to Cigna.
The 90-Day In-Network Standard
Cigna’s own provider policy states that participating provider claims are considered timely when submitted within three months, or 90 days, of the date of service. This is on the tighter end compared to some other major commercial payers, making prompt submission especially important for in-network practices.
The 180-Day Out-of-Network Standard
Out-of-network claims get double the window, 180 days or six months, from the date of service. This wider margin reflects that out-of-network providers may not have the same direct administrative relationship or claims-submission infrastructure as contracted practices.
Consecutive-Day Service Counting
For services spanning multiple consecutive days, such as an inpatient stay, Cigna counts the filing deadline from the last date of service in that continuous period, not from the admission date. This gives providers the full window relative to when the entire episode of care concluded.
Corrected Claim Deadlines
A corrected claim generally must still meet the original filing deadline from the date of service, unless Cigna specifically requested additional information as part of processing the original claim, in which case a different, request-specific deadline may apply instead.
The Appeal Window
Once a claim has been paid or denied, providers have 180 calendar days from that decision to file an appeal, a separate and later deadline from the original claim submission window. This appeal deadline applies broadly, not just to timely filing disputes.
Coordination of Benefits Exceptions
When another payer is primary, Cigna’s timely filing clock for the secondary claim is measured from the processing date on the primary carrier’s explanation of benefits or payment, not from the original date of service, giving providers a fair window after the primary payer’s determination.
State Law and Contract Exceptions
Cigna’s policy explicitly allows for a longer filing period when applicable state law requires it, or when a specific provider agreement grants additional time beyond the standard 90 or 180 days. Practices should check their own contract language rather than assuming the standard deadlines always apply.
Cigna Healthcare for Seniors (Medicare Advantage)
For Cigna’s Medicare Advantage business, non-participating providers follow Medicare’s own processing rules rather than Cigna’s standard commercial deadlines, generally giving 15 to 27 months to file a new claim, substantially longer than the commercial timelines.
No Balance Billing for Timely Filing Denials
Cigna’s provider contracts explicitly prohibit balance-billing the patient when a claim is denied for missing the timely filing deadline. This makes a CO-29 denial a direct loss to the practice rather than a cost that can be recovered from the patient.
How CO-29 Denials Can Sometimes Be Overturned
A CO-29 denial can occasionally be reversed with dated proof the claim was actually received on time, such as a clearinghouse acceptance report, even if the payer’s own system shows a later date. A rejected claim is not proof of timely filing; it still needs to be corrected and resubmitted within the original window.
When Does the 90-Day Rule Apply?
The 90-day rule applies to claims submitted by participating (in-network) providers under a Cigna provider agreement, measured from the date of service or, for consecutive-day stays, the last date of service.
When Does the 180-Day Rule Apply?
The 180-day rule applies to out-of-network provider claims, and separately, to appeals filed after an initial payment or denial decision regardless of network status. Out-of-network billing is common in behavioral health and certain ambulatory surgery settings, making this longer window particularly relevant there.
Best Practices for Meeting Cigna’s Timely Filing Deadline
- Submit claims within days of the encounter rather than batching them toward the end of the filing window.
- Track consecutive-day stays carefully so the filing clock is measured from the correct last date of service.
- Keep a clearinghouse acceptance report for every submission as dated proof of timely filing.
- Flag coordination-of-benefits claims separately, since their clock starts from the primary payer’s EOB date.
- Review provider agreement language for any negotiated exception to the standard 90- or 180-day window.
Mistakes to Avoid With Cigna Timely Filing
- Assuming a rejected claim counts as timely filed without correcting and resubmitting it within the original window.
- Measuring a multi-day inpatient stay’s deadline from the admission date instead of the last date of service.
- Letting claims sit unworked instead of tracking them through active accounts receivable management until submission.
- Attempting to balance-bill a patient for a CO-29 denial, which violates the provider contract.
- Missing the separate 180-day appeal deadline after focusing only on the original filing deadline.
Illustrative Documentation Example
The scenario below is a hypothetical example for teaching purposes, not an actual patient billing case.
A participating provider’s claim for a patient’s three-day hospital stay is submitted 95 days after the discharge date. Because Cigna counts the deadline from the last date of service, the 90-day window closed 5 days earlier, and Cigna returns the claim as CO-29. The practice pulls its clearinghouse log to check whether an earlier submission attempt exists before accepting the denial as final.
Conclusion
Cigna’s timely filing rules are straightforward on paper, 90 days in-network, 180 out, but the details that trip up billing teams are the exceptions: consecutive-day counting, coordination of benefits, and contract-specific extensions. A practice with frequent Cigna volume often benefits from a medical billing audit that checks whether these deadlines are being tracked consistently.
FAQs
Does Cigna’s timely filing limit apply to secondary claims?
No, not in the same way. When Cigna is the secondary payer, the filing clock is measured from the primary payer’s explanation of benefits or payment processing date, not the original date of service.
Can a practice request an extension to Cigna’s filing deadline?
Only under the exceptions Cigna’s policy allows: a specific provider agreement term granting more time, or an applicable state law requiring a longer period. There is no general discretionary extension process for routine late claims.
What is the difference between a rejected claim and a denied claim for timely filing purposes?
A rejected claim never entered Cigna’s adjudication system and must be corrected and resubmitted within the original deadline. A denied claim was processed and formally denied, in this case with CO-29, and follows the appeal process instead.
How does Cigna’s timely filing limit compare to other major payers?
Cigna’s 90-day in-network standard is on the shorter end; some payers allow up to a full year for initial claims. Always check each payer’s specific policy rather than assuming a uniform industry standard.
Does the timely filing clock pause while a claim is pending prior authorization?
Generally no. The date-of-service clock continues to run regardless of authorization status, so practices should not wait for authorization resolution to submit a claim if the filing deadline is approaching.
