UnitedHealthcare Timely Filing Limit

The most important thing to confirm with UnitedHealthcare is not just the number of days, but also what event starts the clock. Some payer documents measure from date of service, some from discharge, and some publish different rules for corrected claims or appeals.

At a glance

• UnitedHealthcare’s official materials state that timely filing is governed by the provider’s Participation Agreement/contract and can vary by state, plan, and line of business. For UnitedHealthcare Community Plan manual examples reviewed, initial claims are 180 days and corrections/resubmissions are 365 days, but the same manual warns that timely filing limits can vary based on state requirements and contracts.

Initial claim filing limits

• Varies by Participation Agreement/contract for Commercial, Exchange, and Medicare Advantage lines in the official sources reviewed.
• UnitedHealthcare Community Plan manual example reviewed: initial claims 180 days.

Corrected claim filing limits

• Varies by Participation Agreement/contract for Commercial, Exchange, and Medicare Advantage lines in the official sources reviewed.
• UnitedHealthcare Community Plan manual example reviewed: resubmissions/corrections 365 days.

Appeal and reconsideration deadlines

• Timelines vary; refer to the Participation Agreement for timely filing information.
• For Community Plan manual examples reviewed, claim reconsideration/appeal timing is tied to the claim issue and contract; specific universal appeal deadlines were not stated in the official sources reviewed.

Trigger basis and caveats

• Official sources cite date of service, discharge, or final outpatient visit as the baseline for claim timeliness.
• For some Community Plan scenarios, the date on the other carrier’s payment correspondence starts the timely filing period for COB-related submissions.
• For corrected claims, UnitedHealthcare states all claim information, including corrections, must be submitted within the required number of days from the relevant service date.
• Timely filing varies by state, contract, line of business, and claim scenario.
• The 2026 administrative guide reviewed explicitly says to refer to the Participation Agreement for timely filing information.
• Community Plan examples should not be assumed to apply to Commercial, Exchange, or Medicare Advantage unless the specific contract says so.
