What is the appeals process for denied claims with Humana?
Short answer
Insurance question
If Humana denies your claim or prior authorization request, you have the legal right to appeal. The standard process involves a first-level internal appeal with Humana, followed by an external independent review if the internal appeal is denied. Medicare Advantage members have a separate, CMS-supervised appeals process with additional stages and timelines.

Key facts
Federal law requires all health plans to have an internal appeals process and guarantees access to external independent review for most commercial plans.
Medicare Advantage members have up to 5 appeal levels supervised by CMS, including expedited options for urgent medical situations.
Medicare.gov — Appeals in Medicare health plans (Medicare Advantage).
Expedited commercial plan appeals (when delay would jeopardize health) require a response within 72 hours.
Here's the nuance
A one-liner rarely tells the whole story. This is the honest detail behind the short answer above.
When Humana denies a claim — whether for coverage of a service, prior authorization, or continued care — federal law guarantees your right to appeal that decision. Understanding the process and acting within the required timeframes is essential.
For Humana commercial and ACA marketplace plan members, the appeals process generally works in two levels. First, you file an internal appeal with Humana, providing documentation of why you believe the denial was incorrect — such as a letter of medical necessity from your physician, clinical guidelines supporting coverage, or evidence that the service is a covered benefit under your plan. Humana is required to review the appeal and issue a written decision within specific timeframes: typically 30 days for a pre-service (prior auth) appeal and 60 days for a post-service (claim payment) appeal. Expedited appeal processing (within 72 hours) is available when a standard timeline would seriously jeopardize your health.
If Humana upholds the denial at the internal level, you have the right to request an external independent review. An independent review organization (IRO) — a neutral third party not affiliated with Humana — reviews your case and issues a binding decision. If the IRO decides in your favor, Humana must comply. The IRO request is typically submitted within 4 months of the final internal appeal denial.
For Humana Medicare Advantage members, the appeals process has up to five levels supervised by CMS: (1) redetermination by the plan, (2) reconsideration by a Qualified Independent Contractor (QIC), (3) Office of Medicare Hearings and Appeals (OMHA) hearing, (4) Medicare Appeals Council review, and (5) federal court review. Expedited appeals (for urgent medical situations) require Humana to respond within 72 hours at the plan level. Detailed timelines and forms are available at Medicare.gov.
In all cases, request the denial in writing, document the reason cited, and ask your physician to support the appeal with a letter of medical necessity. Keep copies of everything you submit.
The key points
The handful of things that decide the answer — skim these if you only read one section.
You have a legal right to appeal any Humana denial
Federal law requires Humana to have an appeals process. You cannot be blocked from appealing a denied claim, prior authorization, or coverage decision.
Level 1: internal appeal with Humana
Submit a written appeal with supporting documentation (physician letter, clinical guidelines). Humana must respond within federally set timeframes — 30 days for pre-service appeals, 60 days for post-service, 72 hours for urgent situations.
Level 2: external independent review — binding on Humana
If Humana upholds the denial internally, you can request an external review by a neutral Independent Review Organization. If the IRO rules in your favor, Humana must comply. This right applies to most commercial and ACA plans.
Medicare Advantage members have up to 5 appeal levels
Humana MA denials can be appealed through CMS's five-level Medicare appeals process, from plan redetermination through federal court. Expedited appeals (72-hour response) are available for urgent medical situations.
Time limits apply — act promptly
Each appeal stage has submission deadlines. Missing a deadline can forfeit your appeal rights at that level. The deadline for internal appeal is typically 180 days from the denial notice for commercial plans. Check your denial letter for specific deadlines.

Frequently Asked Questions
Start by reviewing your Explanation of Benefits (EOB) or denial notice, which explains the reason for denial and lists the appeal rights and deadlines. Submit your appeal in writing to the address listed in the denial notice, including your member ID, a description of the service, the reason you believe the denial was incorrect, and any supporting documentation from your physician. You can also call Humana Member Services for guidance on where to submit the appeal for your specific plan type.
For commercial and ACA marketplace plans, Humana must respond to a pre-service (prior authorization) appeal within 30 days and a post-service (claim payment) appeal within 60 days. Urgent care appeals must be processed within 72 hours. For Medicare Advantage members, plan-level redetermination must occur within 60 days for standard appeals and 72 hours for expedited appeals. Check your denial notice for the specific timeframes that apply to your case.
If Humana upholds the denial at the internal appeal level, you can request an external independent review. The external reviewer is a neutral organization not affiliated with Humana, and their decision is binding on Humana. For Medicare Advantage members, additional appeal levels through CMS are available beyond the plan level. Each stage has its own submission deadline — act promptly after receiving each denial to preserve your rights.
Yes. Your state's Consumer Assistance Program (CAP) or Insurance Commissioner's office can provide free assistance navigating the appeals process. Patient advocates, social workers, and some non-profit organizations also provide appeal support. Your physician can assist by writing a detailed letter of medical necessity. For Medicare Advantage disputes, the State Health Insurance Assistance Program (SHIP) offers free counseling to Medicare beneficiaries — find your local SHIP through Medicare.gov.
An expedited appeal is for situations where following the standard appeal timeline would seriously jeopardize your health, safety, or ability to regain maximum function. For commercial plans, expedited appeals must be decided within 72 hours. For Humana Medicare Advantage, expedited redeterminations also require a 72-hour response from the plan. Request expedited status in your appeal letter and ask your physician to confirm why the standard timeline is insufficient.
