Complete Humana Appeal Process Guide: Every Level, Every Deadline, Every Phone Number
Humana is one of the largest health insurers in the United States, serving more than 17 million members across Medicare Advantage, commercial employer plans, individual marketplace plans, dental, vision, and TRICARE. When Humana denies a claim, you have the right to appeal — but the process differs significantly depending on your plan type. This guide covers the complete appeal process for both commercial and Medicare Advantage plans, with every deadline, phone number, and address you need.

Commercial Plan Appeals: 3-Level Process
For Humana members with commercial health insurance — employer group plans or individual marketplace plans — the appeals process has three levels:
Level 1: Internal Appeal
You have the right to file an internal appeal with Humana after any claim denial or adverse benefit determination.
Deadline: Most ACA-compliant Humana plans allow 180 days from the date of the denial to file a Level 1 appeal. ERISA-governed plans may have shorter timelines specified in the Summary Plan Description — check your plan documents.
How to file:
- Online: MyHumana portal at humana.com
- Phone: 1-800-457-4708
- Mail: Humana Grievances and Appeals, P.O. Box 14546, Lexington, KY 40512
- Fax: Check your denial letter for the specific fax number for appeals
Timeline for Humana's response:
- Standard: 60 days (30 days for pre-service/Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization appeals; 60 days for post-service payment disputes) — ACA requires 60 days for post-service and 15 days for pre-service urgent care
- Expedited: 72 hours if standard timeframe would seriously jeopardize your health or your ability to regain maximum function
What to include:
- Member ID, group number, claim reference number
- Copy of the denial letter
- A detailed letter of medical necessity from your treating physician addressing each denial criterion
- Relevant medical records, lab results, imaging, and specialist notes
- Clinical guidelines supporting your treatment (from medical societies)
- Statement addressing the specific criteria Humana cited in the denial
Who reviews it: The reviewer must be someone not involved in the original denial and must be a clinical peer (physician with appropriate expertise) for clinical denials.
iro">Level 2: External Independent Review: Complete Guide" class="auto-link">External Review by IRO
If Humana upholds the denial on internal appeal, or fails to respond within the required timeframe (which itself constitutes a deemed denial), you have the right to external review by an Independent Review Organization (IRO).
Deadline: You must request external review within 4 months (approximately 122 days) of receiving the Level 1 denial.
How it works: An independent medical professional with expertise in your condition reviews Humana's decision and the clinical evidence. The IRO's decision is binding on Humana — if the IRO reverses the denial, Humana must provide coverage.
How to file: Request external review through:
- Your state's external review program (contact your state's Department of Insurance)
- The federal external review process (administered through URAC or ACME) if your state doesn't have an approved external review process
External review overturns between 40% and 60% of denials across all insurers.
Level 3: Legal Action
If external review upholds the denial, your remaining options depend on your plan type:
- ERISA plans (employer-sponsored): File suit in federal district court. You must have exhausted all internal and external appeal levels first.
- State-regulated plans (individual marketplace): File suit in state court. Consult with an insurance bad faith or ERISA attorney.
For ERISA disputes, the Department of Labor's Employee Benefits Security Administration (EBSA) can investigate complaints: 1-866-444-EBSA (1-866-444-3272).
Medicare Advantage Appeals: 5-Level Process
Humana Medicare Advantage members have a distinct five-level appeal process governed by federal CMS regulations.
Level 1: Humana Plan Reconsideration
Deadline: 60 days from the denial notice to file.
How to file:
- Online: MyHumana portal at humana.com
- Phone: 1-800-457-4708
- Mail: Humana Grievances and Appeals, P.O. Box 14546, Lexington, KY 40512
Timeline: 30 days (pre-service/coverage disputes); 60 days (payment disputes); 72 hours (expedited)
Expedited appeals: If standard timeframe would seriously jeopardize your health, call Humana and explicitly request an expedited review. Your physician must certify the urgency.

Level 2: Qualified Independent Contractor (QIC) Review
Deadline: 60 days from the Level 1 decision.
How to file: Follow the instructions in Humana's Level 1 decision letter — the QIC is assigned by CMS and contacted via the process described in the denial.
Timeline: 60 days (standard); 72 hours (expedited)
The QIC is completely independent of Humana and reviews your evidence de novo.
Level 3: Administrative Law Judge (ALJ) Hearing at OMHA
Deadline: 60 days from the QIC decision.
Amount in controversy requirement: Approximately $180 (adjusted annually).
What it is: A formal hearing before a federal Administrative Law Judge at the Office of Medicare Hearings and Appeals (OMHA). You can submit evidence, call witnesses, and present legal arguments. Reversal rates at the ALJ level are high for well-documented cases.
Level 4: Medicare Appeals Council (DAB)
Deadline: 60 days from the ALJ decision.
What it is: A paper review by the Departmental Appeals Board's Medicare Appeals Council.
Level 5: Federal District Court
Deadline: 60 days from the DAB decision.
Amount in controversy requirement: Approximately $1,760 (adjusted annually).
At this level, you will almost certainly need an attorney.
Grievances vs. Appeals: Know the Difference
An appeal challenges a denial of coverage or payment — a determination that Humana won't cover a service or pay a claim.
A grievance is a complaint about the quality of care or service — including poor customer service, billing problems, network access issues, or concerns about care quality. Humana must respond to grievances within 30 days (standard) or 24 hours (expedited quality-of-care grievances).
File a grievance AND an appeal if your situation involves both a denial and a service quality concern.
Tips for Winning Your Humana Appeal
Respond to the specific denial rationale. Vague appeals fail. Address every criterion Humana cited with specific evidence.
Get a letter from your physician. A clinical letter of medical necessity that cites Humana's specific criteria and demonstrates how your situation meets them is the most important document in your appeal.
Request a peer-to-peer review. Your physician can call 1-800-523-0023 to speak directly with Humana's clinical reviewer — this often resolves clinical denials faster than the formal appeal process.
Submit within the deadline. Missed deadlines forfeit your appeal rights. File early with the documentation you have, then supplement.
Keep records of everything. Document every call, save every letter, and send written submissions via certified mail with return receipt.
