Molina Healthcare of Iowa timely filing limit
Short answer
The Molina Healthcare of Iowa timely filing limit is 180 calendar days for in-network providers, counted from the date of service for outpatient care or from discharge for an inpatient stay. Out-of-network providers get 365 days.
A claim billed after another carrier gets 365 days from the last date on that carrier's EOB, and a corrected claim gets 365 days from the last adjudication date, up to 2 years from the date of service. A first-level claim dispute is due within 180 days of the date on Molina's EOP or remittance advice. These figures come from the Molina manual, quick reference guide and training slides Iowa HHS posts for IA Health Link providers. Compare other payers in the timely filing limits table.

The windows
- Initial claim
- 180 calendar days from the date of service for in-network outpatient claims, or from discharge for inpatient stays; 365 calendar days for out-of-network providers1
- Counted from
- The date of service for outpatient claims and the discharge date for inpatient stays. A claim billed after another carrier counts from the last date on the primary carrier's EOB, a corrected claim from the last adjudication date, and a claim dispute from the date on Molina's EOP or remittance advice.
- Appeal
- 180 days from the date on the EOP or provider remittance advice for a first-level claim dispute, then 30 days from that decision for a second-level dispute
- Corrected claim
- 365 calendar days from the last adjudication date of the claim, for up to 2 years from the date of service. Bill frequency code 7 to replace the claim or 8 to void it, with the original Molina claim number, or the correction denies as a duplicate.

Your participation agreement can set a different window. Where the contract and the manual disagree, the contract applies.
A visit on Monday, March 2, 2026
Counting 180 days forward from a date of service of Monday, March 2, 2026 gives Saturday, August 29, 2026. That is the last day to file under the first limit shown above; a claim filed after it is outside the window unless one of the exceptions below applies.
Exceptions the payer allows
Another carrier pays first
Medicaid is the payer of last resort, so bill the other carrier first and send Molina the claim with the primary EOB within 365 days of the last date on that EOB. In Molina's October 2025 Iowa update, a missing primary EOB on a secondary claim was the most frequent claim edit, so attach it every time.
Out-of-network providers
A provider outside Molina's Iowa network gets 365 calendar days after discharge or from the date of service, not the 180 days a network provider gets. The claim still has to meet Molina's billing rules and include medical records when Molina asks for them.
Late disputes with good cause
A claim dispute or reconsideration filed after the 180-day or 30-day window is treated as untimely and denied unless Molina can validate good cause. Send the reason for the delay and the documents that prove it with the dispute.
Commercial coverage found after Molina paid
When a commercial plan turns out to be primary on a claim Molina already paid, Molina gives notice within 270 days of the claim's paid date and asks for the overpayment back. You can resubmit the claim to Molina with the primary EOB after the commercial plan processes it.
What counts as proof of timely filing
- The 999 and 277CA acknowledgements your clearinghouse returns, which Molina's manual tells you to track because they show the claim was received for processing
- The clearinghouse clean date for an electronic claim, or the date Molina received a clean paper claim, since Molina counts receipt from that date
- For a claim billed after another carrier, the primary carrier's EOB, whose last date starts the 365-day window
- For a claim dispute, the EOP or remittance advice date and your supporting documents, each marked with the Molina claim number
Notes for billers
- Molina's Iowa payer ID is MLNIA. Submit claims through the Availity Essentials portal or your clearinghouse; Molina's gateway clearinghouse is SSI. Paper claims are accepted only on original red and white CMS-1500 or UB-04 forms, typed, and count as accepted only once they reach the correct claims PO box.
- For an EDI correction, put the original claim number in Loop 2300 REF02 with qualifier F8 in REF01. Without it the adjustment fails compliance editing and rejects. On paper, the original claim number goes in Box 22 of the CMS-1500 or field 64 of the UB-04.
- Molina says it will strive to process clean claims within 30 calendar days of receipt, and it sends a written decision on a claim dispute within 60 calendar days. A provider who finds an overpayment must report it and pay it back within 60 calendar days.
- The 2023 manual gives 90 days from the overpayment letter to dispute an overpayment. Molina's October 2025 Iowa update gives 45 days from the overpayment notification to dispute a cost recovery finding through Availity, so work to 45 days.
- Molina Healthcare of Iowa is one of three IA Health Link managed care plans, with Iowa Total Care and Wellpoint Iowa. Its manual covers Medicaid, long-term services and supports, and Hawki members, and says providers may never balance bill members for covered services.
- Iowa HHS posts the 2023 edition of Molina's Iowa provider manual, last updated May 1, 2023. The manual says Molina customarily updates it each year and keeps the current edition at MolinaHealthcare.com, and your provider agreement can set different terms, so check both before you rely on a date.
