Policy Overview: How Humana Covers Hemlibra

Humana Medicare Advantage and Part D plans classify Hemlibra on the Specialty Tier (Tier 4) with 25-33% coinsurance after prior authorization approval. The drug falls under Medicare Part B when administered in clinical settings or Part D for home administration through specialty pharmacy.

Plan Types and Applications

  • Medicare Advantage (Part C): Covers Hemlibra with prior authorization; follows Medicare guidelines with plan-specific formulary placement
  • Medicare Part D: Requires specialty pharmacy dispensing; coverage subject to formulary tier and PA requirements
  • Commercial plans: Vary by employer group; generally follow similar medical necessity criteria

You can verify your specific plan's formulary status through Humana's drug lookup tool or by calling member services.

Indication Requirements: FDA and Medical Necessity

FDA-Approved Indications

Hemlibra is FDA-approved for routine prophylaxis to prevent or reduce bleeding episodes in patients with hemophilia A (congenital factor VIII deficiency) with or without factor VIII inhibitors. The approval covers patients 1 year and older.

Humana's Medical Necessity Criteria

Humana typically requires documentation of:

  • Primary diagnosis: Hemophilia A (ICD-10 code D66)
  • Disease severity: Factor VIII activity levels <5% (moderate to severe)
  • Inhibitor status: For patients with inhibitors, documented titer ≥5 Bethesda units
  • Clinical need: History of bleeding episodes requiring prophylactic treatment
Note: Off-label use for acute bleeding treatment is typically denied and requires robust clinical justification.

Step Therapy & Exceptions

Standard Step Therapy Requirements

For hemophilia A patients without inhibitors, Humana Medicare plans often require trials of two factor VIII concentrates before approving Hemlibra:

Step 1 Options:

  • Adynovate, Afstyla, Altuviiio, Jivi, Kovaltry, Nuwiq

Step 2 Options:

  • Advate, Kogenate, Novoeight, Recombinate, Xyntha

Medical Exception Pathways

Step therapy can be bypassed with documentation of:

  • Factor VIII inhibitors (≥5 Bethesda units)
  • Contraindications to factor VIII products
  • Inadequate response to factor concentrates despite appropriate dosing
  • Intolerance to factor VIII with documented adverse reactions

Submit exception requests with the initial PA application, including clinical notes documenting the medical rationale.

Quantity and Frequency Limits

Dosing Parameters

Humana covers FDA-approved dosing regimens based on patient weight:

Loading Dose: 3 mg/kg subcutaneously weekly for 4 weeks

Maintenance Options:

  • 1.5 mg/kg weekly
  • 3 mg/kg every 2 weeks
  • 6 mg/kg every 4 weeks

Quantity Limits and Renewals

  • Initial approval: Up to 6 months with clinical response documentation
  • Renewal requirements: Bleeding episode logs, adherence records, continued medical necessity
  • Dose escalation: Requires documentation of breakthrough bleeding on standard dosing

Coverage is limited to FDA-recommended maximums unless exceptional circumstances are documented with peer-reviewed evidence.

Required Diagnostics and Documentation

Essential Laboratory Tests

Baseline Requirements:

  • Factor VIII activity level (within 12 months)
  • Factor VIII inhibitor screen and titer (Bethesda assay)
  • Complete blood count and comprehensive metabolic panel
  • Coagulation studies (PT/INR, aPTT)

For Inhibitor-Positive Patients:

  • Bethesda titer ≥5 units (high-titer) or documented low-titer with clinical bleeding
  • Historical response to factor VIII concentrates

Clinical Documentation Timing

  • Laboratory results must be within 12 months of PA submission
  • Bleeding episode logs should cover 6-12 months prior to request
  • Prior treatment history with outcomes and durations

Counterforce Health helps clinicians organize these requirements into compelling prior authorization submissions that address payer-specific criteria systematically.

Site of Care and Specialty Pharmacy Requirements

Approved Administration Settings

Humana covers Hemlibra administration in:

  • Home setting (most common after training)
  • Physician office
  • Outpatient infusion center (when medically necessary)
  • Hospital outpatient department (exceptional cases only)

Specialty Pharmacy Network

Hemlibra must be dispensed through Humana's contracted specialty pharmacies. The HEMLIBRA Access Solutions program coordinates with over 100 in-network specialty pharmacies and can help identify Humana-preferred providers.

Required Steps:

  1. Enroll through HEMLIBRA Access Solutions
  2. Submit Patient Consent Form and Prescriber Service Form
  3. Coordinate with Humana-approved specialty pharmacy for dispensing

Evidence to Support Medical Necessity

Primary Guidelines and Citations

When building your medical necessity case, reference these authoritative sources:

  • FDA prescribing information for approved indications and dosing
  • World Federation of Hemophilia guidelines for prophylaxis recommendations
  • CDC hemophilia care guidelines for inhibitor management
  • International Society on Thrombosis and Haemostasis (ISTH) recommendations

Clinical Evidence Requirements

Include peer-reviewed studies supporting:

  • Efficacy in similar patient populations
  • Safety profile for proposed duration
  • Comparative effectiveness vs. alternatives when applicable

Keep citations concise but authoritative—payers review hundreds of requests and appreciate well-organized, evidence-based submissions.

Sample Medical Necessity Narrative

Template Paragraph Structure:

"[Patient] is a [age]-year-old with severe hemophilia A (factor VIII <1%) and high-titer inhibitors (Bethesda titer [X] units) experiencing [frequency] bleeding episodes despite [prior treatments]. Factor VIII concentrates are contraindicated/ineffective due to [inhibitor status/adverse reactions]. Hemlibra prophylaxis at [dose] is medically necessary per FDA labeling and WFH guidelines to prevent life-threatening bleeding complications. Expected outcome: >50% reduction in bleeding episodes based on clinical trials. Monitoring plan includes [schedule] assessments for breakthrough bleeding and adherence."

Edge Cases and Special Considerations

Pediatric Patients (1-12 years)

  • Weight-based dosing calculations required
  • Caregiver training documentation for home administration
  • Pediatric hematologist involvement typically strengthens approval

Pregnancy Considerations

  • Limited data requires case-by-case review
  • Maternal-fetal medicine consultation recommended
  • Alternative options assessment required

Comorbidity Considerations

  • Renal impairment: No dose adjustment typically needed
  • Hepatic impairment: Monitor for bleeding risk
  • Concurrent anticoagulants: Requires careful risk-benefit analysis

Escalation Pathways

For complex cases, request peer-to-peer review with Humana's medical director. This allows direct clinician-to-clinician discussion of unusual circumstances or cutting-edge applications.

Appeals Process in New Jersey

Humana Internal Appeals

Timeline: 65 days from denial notice Method: Online portal, phone (866-421-5663), or written appeal Required: Original denial letter, additional clinical documentation, updated medical necessity letter

Expedited Appeals: 72 hours for urgent cases where delay could jeopardize health

New Jersey External Review (IHCAP)

If Humana's internal appeal is denied, New Jersey residents can access the Independent Health Care Appeals Program (IHCAP) administered by Maximus Federal Services.

Eligibility:

  • Fully-insured plan (not self-funded employer plans)
  • Denial based on medical necessity
  • Internal appeals completed
  • Filed within 4 months of final denial

Filing Process:

  1. Submit through Maximus IHCAP Portal
  2. Include appeal form, denial letters, medical records release
  3. Pay required fee (amount specified on form)

Timeline:

  • Standard review: 45 calendar days
  • Expedited review: 48 hours for urgent cases
  • Binding decision on insurance plan

The external review process is particularly effective for specialty drugs like Hemlibra when clinical evidence supports medical necessity but payer policies are overly restrictive.

Counterforce Health's platform can help organize your appeal documentation to meet both Humana's requirements and New Jersey's IHCAP standards, ensuring nothing is missed in the process.

FAQ
