How long do I have to appeal a Humana denial?

Humana commercial plans allow 180 calendar days from the denial date. Humana Medicare Advantage appeals must be filed within 65 calendar days of the denial notice (CMS mandates a 60-day minimum; Humana, like UnitedHealthcare, implements 65 as a uniform policy). Humana Medicaid plans generally run 60 days. Since most Humana volume is Medicare Advantage, treat 65 days as the default operating assumption unless the plan type says otherwise.

How do I submit a Humana provider appeal?

Availity Essentials is Humana's provider portal for disputes, claim status, and documentation. Medicare Advantage appeals can also be submitted through Humana's dedicated resolutions channel (Resolutions.Humana.com) or to the address on the denial notice. Whatever the channel, keep the case or confirmation number — it is your proof of a timely filing.

What happens after a Humana Medicare Advantage appeal is denied?

The federal MA appeal ladder takes over: if Humana upholds its denial at Level 1 reconsideration, it must automatically forward the case to the Independent Review Entity (MAXIMUS) — you don't have to request it. Beyond the IRE, cases can proceed to an ALJ hearing, the Medicare Appeals Council, and federal court, with each level's deadline running from the previous decision. Standard Level 1 decisions take 30 days; expedited, 72 hours.

What changed for Medicare Advantage prior authorization in 2026?

Under CMS-0057-F, effective January 1, 2026, MA plans must decide standard prior authorization requests within 7 calendar days and expedited requests within 72 hours, and denials must cite specific clinical reasons. Use the plan's own stated denial reason verbatim as the frame for your rebuttal — it defines exactly what your appeal must disprove.

Humana's trap: the 180-day number that doesn't apply to most of your claims

On paper, Humana looks like Aetna and Cigna: 180 calendar days to appeal a commercial denial. In practice, Humana is overwhelmingly a Medicare Advantage company — and its MA appeals run on a 65-day window from the denial notice (CMS mandates 60 as the floor; Humana, like UnitedHealthcare, implements 65 across its MA book). Humana Medicaid plans generally allow 60 days. The failure mode is obvious: a billing team that files everything on "commercial time" quietly forfeits its MA appeals.

Operating rule: treat 65 days as the Humana default, and let the 180-day commercial window be the pleasant surprise, not the assumption. The clock runs from the date printed on the denial notice, not the day it was opened. Get exact dates for any plan with our deadline checker.

The MA appeal ladder works for you — if you file Level 1 on time

Humana MA denials follow the federal Part C process (42 CFR Part 422). File a written Level 1 reconsideration within 65 days — via Availity, Humana's resolutions channel (Resolutions.Humana.com), or the address on the denial notice. Standard decisions take 30 days; expedited, 72 hours where delay would jeopardize the patient.

Here's the structural gift of the MA system: if Humana upholds its own denial, it must automatically forward your case to the Independent Review Entity (MAXIMUS) — a federal contractor outside Humana. You don't request it; it happens. That means a well-built Level 1 file is really an audition for an independent reviewer, so write it for a stranger: complete records, clear criteria mapping, nothing assumed. Beyond the IRE, the ladder continues to an ALJ hearing, the Medicare Appeals Council, and federal court, each deadline running from the prior decision.

New for 2026 under CMS-0057-F: MA plans must decide standard prior auths in 7 calendar days (72 hours expedited) and must cite specific clinical denial reasons. Use Humana's own stated reason verbatim as the skeleton of your rebuttal — it tells you exactly what to disprove. And keep pre-service PA appeals and post-service claim appeals in their separate tracks; mixing the two changes which forms and timelines apply.

Building the letter: Humana's policies + Medicare's coverage rules

Humana evaluates medical necessity against its published medical coverage policies — and for MA claims, those sit on top of Medicare's own NCD/LCD coverage determinations. The strongest MA appeals address both layers: cite the Humana policy the denial referenced (name and number), and where a Medicare NCD/LCD governs the service, show the patient meets it. Then the universal structure: quote the criteria, map the documented clinical findings to each point, attach exactly the records that prove each one. For denials tied to timely filing (CO-29), the proof standard is the same as every payer — a clearinghouse EDI acceptance report tied to the claim, per our CO-29 guide. Recurring denial patterns are cheaper to fix upstream: see how to reduce claim denials.
