Timely filing · commercial and Medicare Advantage
Humana timely filing limit
Short answer
Humana's timely filing limit for Medicare Advantage claims is one year from the date of service, applied when your agreement and state or federal law do not specify another period. The 2025 Provider Manual publishes no default for commercial plans, so the commercial window is whatever your participation agreement says. Medicaid plans follow the state-specific Humana Medicaid manual.
If you disagree with how a claim was adjudicated, a claim dispute or reopening request has to reach Humana within 18 months of the date the claim was paid, again unless law or your agreement sets a different period. Disputes are filed through Availity Essentials from the Claim Status tool. Compare other payers in the timely filing limits table.

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 one year forward from a date of service of Monday, March 2, 2026 gives Tuesday, March 2, 2027. 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
Your agreement or the law sets a different period
The one-year Medicare figure in the manual is a fallback. Where your participation agreement, a state law or a federal rule specifies a filing period, that period applies instead, whether longer or shorter.
Medicaid lines of business
Humana Medicaid plans (Humana Healthy Horizons) are excluded from the manual's general time frame. Their filing limits sit in the state-specific Medicaid provider manual and change by state.
What counts as proof of timely filing
- The clearinghouse acceptance report showing Humana received and accepted the original claim, with the patient, date of service and submission date
- The 277CA acknowledgement for the original submission
- The remittance for the original claim when you are disputing a paid or denied line
- For paper claims, a certified mail receipt tied to the claim batch
Notes for billers
- The 2025 Provider Manual lists filing time frames only for Medicare and Medicaid lines of business; it does not state a commercial default. Check the agreement before assuming a number.
- Disputes are submitted online through Availity Essentials (Claim Status tool, Dispute Claim), by fax or by mail. A provider who is unhappy with the outcome can ask for an escalated review through Humana's Provider Concierge Unit.
- Selecting Dispute Claim in the Availity Claim Status tool only adds the claim to your Appeals worklist; Humana receives the dispute when you submit it from that worklist. The online function covers finalized Medicare, Medicaid and commercial claims, not preauthorization appeals without a claim and not overpayment or payment integrity disputes.
- A mailed dispute goes to Humana Correspondence, P.O. Box 14601, Lexington, KY 40512-4601, and has to carry the provider's name and TIN, the member's Humana ID, the date of service and claim number, the charged, paid and expected amounts, and the reason you are contesting the payment. Do not resubmit online a dispute you already mailed; Humana says duplicates can slow processing.
- A participating provider who disagrees with Humana's answer can escalate by secure email to HumanaProviderServices@humana.com with the Claim Escalation Form, listing every reference or interaction number from earlier attempts.
- Humana's manual does not list accepted proof of timely filing; the proofs above are the ones payers generally accept.
