Ambetter Health of Florida, Timely Filing Limit

The most important thing to confirm with Ambetter Health of Florida, 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

• The Florida provider toolkit states timely filing is 180 days from date of service. The 2026 provider manual shows 180 days for initial claims and 90 days for claim reconsiderations/appeals, with coordination-of-benefits claims tied to the primary payer EOP date. For disputes/appeals and reconsiderations, the manual uses the date of the EOP or denial letter as the trigger.

Initial claim filing limits

• 180 days from date of service for initial claims
• For observation and inpatient stays, the filing clock is calculated from the discharge date

Corrected claim filing limits

• Corrected claim timing is not stated as a separate deadline in the sources reviewed; corrected claims must be submitted within the applicable filing deadline
• Claim records rejected by clearinghouse or plan edits must be corrected and resubmitted within the required filing deadline

Appeal and reconsideration deadlines

• Request for Reconsideration must be received within 90 calendar days from the date of the original explanation of payment or denial
• Claim Disputes must be received within 90 calendar days from the date of the Request for Reconsideration denial letter

Trigger basis and caveats

• Initial claims: date of service to date received, or from EOP date for certain scenarios
• Claims Dispute/Appeals: date of the EOP issued by Ambetter to date received
• Coordination of Benefits: date of the primary payer EOP to date received
• The quick reference guide only states 180 days from date of service and does not break out appeals or COB.
• The 2026 manual indicates untimely reconsiderations/disputes are administratively upheld/denied unless a qualifying circumstance is documented.
