Eligibility Triage: Do You Qualify?

FDA-Approved Indications for Bavencio

Bavencio is approved for two specific cancer types. Check which category applies to you:

Metastatic Merkel Cell Carcinoma (MCC)

  • ✅ Likely eligible if: You have locally advanced, recurrent, or metastatic MCC confirmed by biopsy
  • ✅ Age requirement: Adults and pediatric patients ≥12 years
  • ✅ Prior therapy: No specific requirements (can be first-line treatment)

Urothelial Carcinoma (Bladder Cancer)

  • ✅ Likely eligible if: You have locally advanced or metastatic disease AND completed first-line platinum-based chemotherapy without progression
  • ✅ Treatment setting: Maintenance therapy only (not for active progression)
  • ✅ Prior therapy: Must have received platinum-containing regimen (cisplatin or carboplatin)

Standard dosing for both: 10 mg/kg intravenously every 2 weeks, according to FDA prescribing information.

Quick Eligibility Check

Answer these questions to determine your likely approval path:

  1. Do you have confirmed MCC or urothelial carcinoma? (Pathology report required)
  2. For urothelial carcinoma: Did you complete platinum chemotherapy without disease progression? (Treatment records needed)
  3. Are you enrolled in a Humana Medicare Advantage or Part D plan? (Check your insurance card)
  4. Can you receive infusions at a Humana-approved facility? (Verify with member services)

If "Likely Eligible": Your Document Checklist

When your case fits FDA criteria clearly, focus on assembling complete documentation for smooth prior authorization approval.

Required Clinical Documentation

Diagnosis Confirmation:

  • Pathology report with specific cancer type and staging
  • ICD-10 codes (C44.10-C44.19 for MCC; C67.x for bladder cancer)
  • Current imaging showing disease extent

Treatment History (for Urothelial Carcinoma):

  • Records of completed platinum-based chemotherapy
  • Response assessment showing stable disease or partial response
  • Timeline showing maintenance setting (no progression)

Current Status:

  • Recent performance status assessment
  • Laboratory values (CBC, comprehensive metabolic panel)
  • Contraindication screening (autoimmune conditions, immunosuppression needs)

Submission Process

Step 1: Provider Initiates Request Your oncologist submits prior authorization through Evolent's provider portal or by phone/fax as listed in Humana's current guidance.

Step 2: Timeline Expectations

  • Standard review: Up to 14 days for non-urgent requests
  • Expedited review: 72 hours if medically urgent
  • Additional information requests may extend timeline

Step 3: Coverage Verification Confirm your specific plan's specialty pharmacy network and infusion site requirements before scheduling treatment.

Tip: New Humana members already receiving oncology treatment get a 90-day grace period without prior authorization, but claims will be reviewed for medical necessity.

If "Possibly Eligible": Tests and Timeline

When your situation has gaps or uncertainties, use this section to strengthen your case before submitting.

Missing Documentation to Obtain

For Unclear Diagnosis:

  • Request immunohistochemistry staining to confirm Merkel cell markers
  • Obtain molecular testing if pathology is inconclusive
  • Get staging studies (CT chest/abdomen/pelvis, bone scan if indicated)

For Treatment History Questions:

  • Gather complete chemotherapy records from all treating facilities
  • Document specific platinum agents used and number of cycles
  • Obtain response assessment imaging from end of first-line therapy

Timeline to Reapply

Immediate (within 1-2 weeks):

  • Order missing lab work or imaging
  • Request records from previous oncologists
  • Schedule staging procedures if needed

30-60 days:

  • Complete any required "step therapy" with preferred alternatives
  • Document treatment failures or intolerances
  • Reassess disease status if time has elapsed

When to expedite: If disease progression occurs while gathering documentation, request expedited review citing urgent medical need.

If "Not Yet Eligible": Alternatives and Exceptions

When you don't meet standard criteria, explore these pathways before giving up on coverage.

Alternative Treatments to Consider

For Merkel Cell Carcinoma:

  • Clinical trial enrollment (may provide free drug access)
  • Pembrolizumab (Keytruda) - another checkpoint inhibitor with similar efficacy
  • Radiation therapy for localized disease

For Urothelial Carcinoma:

  • Enfortumab vedotin combinations for progression cases
  • Nivolumab for patients who progressed during platinum therapy
  • Clinical trials for novel agents

Exception Request Strategies

Medical Necessity Appeals: When standard criteria don't fit your situation, work with your oncologist to document:

  • Why approved alternatives are contraindicated
  • Unique clinical circumstances requiring Bavencio specifically
  • Supporting literature for off-label use (if applicable)

Step Therapy Exceptions: If Humana requires trying other drugs first, request an exception based on:

  • Prior treatment failures outside your current plan
  • Contraindications to preferred alternatives
  • Urgency of treatment initiation

FAQ: Bavencio Coverage by Humana

How long does Humana prior authorization take in California? Standard processing is up to 14 days, but expedited review (72 hours) is available for urgent medical situations. New members in active treatment get 90 days of coverage review rather than upfront denial.

What if Bavencio isn't on my plan's formulary? You can request a formulary exception through your prescriber. If denied, California's IMR process has high success rates (55%+) for medically necessary oncology drugs.

Can I get expedited appeal for cancer treatment? Yes. Both Humana and California's DMHC offer expedited processes (72 hours) when delays would seriously jeopardize your health. Request this specifically when filing appeals.

Does step therapy apply if I failed similar drugs outside California? Document prior treatment failures thoroughly. Humana should consider out-of-state treatment history, but you may need to provide complete records from previous providers.

What's the maximum I'll pay out-of-pocket? For 2026, Medicare Part D has an annual out-of-pocket maximum of $2,100, after which your plan pays 100% of covered drugs including Bavencio.

How do I find Humana-approved infusion centers? Contact member services or check your online portal for network providers. Counterforce Health can also help navigate payer-specific network requirements and site-of-care restrictions.

What if my oncologist isn't familiar with Humana's requirements? Provide them with Humana's current prior authorization forms and requirements. Many practices work with specialty pharmacies or patient access coordinators who handle insurance approvals.

Can I appeal while starting treatment? In urgent situations, yes. Request expedited processing and ask your oncologist about bridge programs or manufacturer assistance while appeals are pending.
