UnitedHealthcare’s timely filing limit for participating commercial claims is generally 90 days from the date of service, non-participating providers get up to 180 days, and noncontracted Medicare Advantage claims get 365 days. UHC’s own 2026 Administrative Guide is explicit that the number governing any specific claim comes from the provider’s Participation Agreement, not a single company-wide rule.
UHC’s Timely Filing Windows by Claim Type
- Participating commercial claims: generally 90 days from the date of service
- Non-participating commercial claims: generally up to 180 days
- Medicare Advantage (noncontracted providers): 365 days from the through date of service
- Community Plan (Medicaid): state-specific, commonly 90 to 180 days — verify the applicable state manual rather than assuming a national figure
- Corrected claims: as of the 2026 Administrative Guide, corrections follow the same filing window as the original claim, measured from the same starting event — an ERA does not reset the clock
- Appeals (commercial): 65 calendar days from the denial date, the shortest appeal window among major payers
- Appeals (Medicare Advantage, Part D, Medicaid Community Plans): 60 days
Why the 65-Day Appeal Window Matters
Aetna, Blue Cross Blue Shield, and Cigna each generally allow 180 days to appeal a denial. UHC’s commercial appeal window is 65 days — less than half that of the other major payers. A billing team that applies a standard 180-day mental model to every payer’s appeals will miss the UHC window entirely on a denial that was otherwise appealable.
Corrected Claims: What the 2026 Guide Clarified
UHC’s 2026 guidance specifically addressed a point of confusion: a corrected claim does not get a fresh clock starting from the date the original ERA arrived. It follows the same Participation-Agreement-defined window as the original claim, counted from the same starting event. A practice that submits an original claim on day 30 and assumes it has a fresh window from the ERA date to submit a correction can end up filing the correction too late without realizing it.
How to Avoid UHC Timely Filing Denials
- Verify network status per claim, since participating and non-participating status can change the deadline by 90 days
- Track separate deadlines by product line — commercial, Individual Exchange, Medicare Advantage, and Community Plan claims can each carry different windows for the same practice
- Calendar the 65-day appeal window separately from the initial filing deadline, since it is meaningfully shorter than other major payers
- Confirm the corrected-claim starting event against the practice’s own Participation Agreement rather than assuming an ERA-based reset
Frequently Asked Questions About UHC Timely Filing
What is UnitedHealthcare’s timely filing limit for commercial claims?
Generally 90 days from the date of service for participating providers and up to 180 days for non-participating providers, though the exact figure is set by the provider’s Participation Agreement.
What is UHC’s appeal deadline?
Generally 65 calendar days from the denial date for commercial plans, and 60 days for Medicare Advantage, Part D, and Medicaid Community Plans. The commercial appeal window is the shortest among major payers.
Does the corrected claim deadline reset after an ERA arrives?
No. As of UHC’s 2026 Administrative Guide, a corrected claim follows the same window as the original claim, measured from the same starting event, not from the date the ERA was received.
What happens if a UHC claim misses timely filing?
The claim is denied, typically under code CO-29, and the practice generally cannot bill the patient for the denied amount. Overturning the denial requires documented proof of timely submission, such as an EDI acceptance report or clearinghouse timestamp.
What OmniBridge Actually Does
We track filing and appeal deadlines by payer, plan, and product line as part of our medical billing service, so a UHC claim never gets the wrong deadline applied to it. See how Aetna’s timely filing rules compare if you also bill that payer.

What is the UnitedHealthcare timely filing limit?
UnitedHealthcare states that providers should refer to their internal contracting contact or Participation Agreement for timely filing information. Its provider guidance gives an example where a 90-day filing requirement would make a May 1 date of service due by July 30. Source: UnitedHealthcare claim returns and rework guidance.
UnitedHealthcare also announced that its 2026 Care Provider Administrative Guide includes updates to corrected-claim timely filing requirements. Source: UnitedHealthcare 2026 Provider Administrative Guide update.
AEO and GEO-ready answer
The safest answer is that UnitedHealthcare timely filing limits are not one universal number for every provider and plan. Billing teams should verify the Participation Agreement, plan type, network status, original claim deadline, corrected claim deadline, and appeal deadline before writing off a claim or assuming it can still be submitted.
