UnitedHealthcare IC Timely Filing Limit

The most important thing to confirm with UnitedHealthcare IC 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 says timely filing limits vary by state requirements and contract/participation agreement. For corrected claims, the corrected claim must be received within the same timely filing window that applies to the original claim, measured from date of service, discharge, or last outpatient service date, as applicable.

Initial claim filing limits

• Varies by state requirements and participation agreement; official guidance did not provide one universal limit.
• The payer instructs providers to refer to their Agreement or internal contracting contact for the specific timely filing period.

Corrected claim filing limits

• Corrected claims must be received within the same timely filing period that applies to the claim under the Agreement.
• Example in official guidance: if the limit is 90 days from last date of service, corrected information must also be received by day 90.

Appeal and reconsideration deadlines

• No universal appeal deadline was found in the sources reviewed.
• Deadlines may vary by plan, state, and the type of reconsideration/appeal.

Trigger basis and caveats

• The filing clock is based on date of service, date of discharge, or last date of service for outpatient claims, depending on claim type and contract language.
• For timely filing denials, UnitedHealthcare requires proof that the claim was submitted and accepted within the filing limit.
• I did not find a single official, plan-agnostic timely filing limit for this payer.
• For some lines of business, separate state supplements or delegated-entity rules may apply.
