Humana Medicare Advantage Claim Denied — How to Appeal

Humana is the second-largest Medicare Advantage insurer in the country, covering millions of seniors through plans like Humana Gold Plus HMO and Humana Choice PPO. Despite its scale, Humana MA members regularly face denied claims and Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization rejections — often for care their doctors say is medically necessary.

If Humana denied your claim, you have federally protected appeal rights. Here's exactly how to use them.

Why Humana Medicare Advantage Denies Claims

Humana MA plans manage costs by requiring prior authorization (PA) for many services and by applying clinical criteria that sometimes go beyond what Original Medicare requires. Common denial reasons include:

• Not medically necessary: Humana's clinical reviewers determined the requested service doesn't meet coverage criteria, even when your doctor disagrees.
• Prior authorization not obtained: The service was provided without advance approval, or the PA request was denied.
• Out-of-network provider (HMO plans): Humana Gold Plus HMO generally limits coverage to in-network providers except in emergencies.
• Skilled vs. custodial care dispute: Humana may classify your care as custodial (not covered) rather than skilled (covered).
• Formulary or step therapy issues: For drug benefits, Humana may deny a medication not on its formulary or require you to try cheaper alternatives first.
• Duplicate billing or coding errors: Administrative errors that appear as coverage denials.

Regardless of the stated reason, you have the right to appeal every denial.

Humana Medicare Advantage Appeal Timelines

Federal rules set by CMS govern Humana's appeal timelines — the plan cannot deviate from them:

• Expedited (urgent) appeal: Humana must decide within 72 hours if your health requires faster action. Request expedited review if waiting could seriously harm you.
• Standard appeal: Humana must decide within 30 calendar days for prior authorization requests and 60 calendar days for post-service claim denials.

Missing these deadlines is a CMS violation you can report.

Step 1 — Request a Peer-to-Peer Review

Before filing a formal appeal, your physician can request a peer-to-peer review — a direct call between your doctor and Humana's medical reviewer. This step isn't required, but it resolves many denials quickly. Peer-to-peer reviews typically must be requested within a few business days of the denial notice. Ask your doctor's office to call Humana's provider line and request one.

Step 2 — File a Level 1 Appeal with Humana

Your Notice of Denial from Humana includes specific instructions for filing an appeal. The Level 1 appeal goes back to Humana for internal review.

What to include:

• A copy of the denial notice
• A letter of medical necessity from your physician
• Supporting clinical records (test results, treatment notes, referrals)
• A written statement explaining why the denial is wrong

Send your appeal by the method specified in your denial letter (mail, fax, or online portal). Keep copies of everything and note the date you submitted. If you need expedited review, state clearly in writing that your condition is urgent.

Step 3 — Level 2 External Independent Review: Complete Guide" class="auto-link">External Review Through MAXIMUS

If Humana upholds the denial at Level 1, you automatically have the right to request a Level 2 external review through MAXIMUS Federal Services, an independent organization contracted by CMS. MAXIMUS reviewers are not employed by Humana and must apply Original Medicare coverage standards.

• Standard review: MAXIMUS has 60 days to decide.
• Expedited review: MAXIMUS has 72 hours.

Request Level 2 review through the information provided in Humana's Level 1 denial letter. MAXIMUS overturns a significant percentage of MA plan denials — this step is worth pursuing.

Steps 4 and 5 — ALJ Hearing and Beyond

If MAXIMUS upholds the denial and the disputed amount meets the minimum threshold (currently around $180 for an ALJ hearing), you can escalate further:

• Level 3: Request a hearing before an Administrative Law Judge (ALJ) through the Office of Medicare Hearings and Appeals (OMHA).
• Level 4: Appeal to the Medicare Appeals Council.
• Level 5: File in Federal District Court (higher dollar threshold applies).

These higher-level appeals are less common but have produced significant wins for beneficiaries, particularly for SNF, home health, and durable medical equipment denials.

Tips for a Stronger Humana MA Appeal

• Get your denial in writing: Humana is required to provide a written explanation. If you received a verbal denial, request written confirmation immediately.
• Cite the right standard: Humana must use Original Medicare coverage criteria as a floor. If Original Medicare would cover the service, say so explicitly.
• Use Jimmo v. Sebelius if applicable: If your denial involves skilled nursing or home health and Humana cited a lack of "improvement," cite this landmark case — the improvement standard is not a valid coverage criterion.
• Act fast: Most appeal deadlines are 60 days from the denial notice. Don't delay.
• File a CMS complaint: If Humana misses its timeline obligations, file a complaint at medicare.gov or call 1-800-MEDICARE.
