Humana's Coverage Policy for Haegarda

Haegarda appears on Humana's 2025 Medicare Prior Authorization List, requiring preauthorization across Medicare Advantage and Dual Eligible Special Needs Plans nationwide. Unlike some specialty medications, Humana doesn't offer North Carolina-specific exemptions for Haegarda coverage.

Plan Types and Coverage

Plan Type PA Required? Special Notes
Medicare Advantage Yes Standard 7-30 day review; 72 hours if expedited
Dual Eligible SNP Yes Same requirements as MA plans
Medicare Part D Check formulary May vary by specific plan

The medication requires approval regardless of whether you're new to Humana or switching from another C1-esterase inhibitor therapy.

Medical Necessity Requirements

Confirmed HAE Diagnosis

Your doctor must document hereditary angioedema with laboratory evidence:

  • Low C4 complement levels during or between attacks
  • Abnormal C1-INH levels: Either low antigenic levels (Type I HAE) or low functional activity (Type II HAE)
  • Normal C1q levels to rule out acquired angioedema
  • ICD-10 diagnosis code: Typically D84.1 (defect in the complement system)
Clinician Tip: Submit all three lab values (C4, C1-INH antigen, C1-INH function) even if only one is abnormal. Include testing dates and reference ranges from your lab.

Clinical History Documentation

Humana expects evidence of:

  • Recurrent angioedema episodes affecting face, lips, tongue, throat, or extremities
  • Abdominal attacks with severe pain, nausea, or vomiting
  • Family history of similar symptoms (if applicable)
  • Poor response to antihistamines, corticosteroids, or epinephrine during attacks
  • Frequency and severity of attacks warranting prophylaxis

Step Therapy and Formulary Placement

Based on current formulary data, Humana typically prefers lanadelumab (Takhzyro) over Haegarda for HAE prophylaxis. You may need to document why Haegarda is medically necessary instead of preferred alternatives.

Common Step Therapy Requirements

  1. Trial of lanadelumab (Takhzyro) unless contraindicated
  2. Documentation of failure, intolerance, or contraindication to preferred agents
  3. Clinical rationale for subcutaneous C1-INH over alternatives

Medical Exceptions

If step therapy applies, document:

  • Allergic reactions to preferred medications
  • Injection site reactions or tolerability issues
  • Dosing frequency preferences (Haegarda twice weekly vs. Takhzyro every 2-4 weeks)
  • Patient/caregiver preference for self-administration training

Required Documentation and Training

Injection Training Requirements

Haegarda requires mandatory training before self-administration. Training typically includes:

  • Reconstitution technique using sterile water for injection
  • Proper injection technique at 90° or 45° angle
  • Site rotation (minimum 5 cm apart, usually abdominal area)
  • Competency demonstration with healthcare professional

Training is provided through the HAEGARDA Connect program, often including in-home nursing visits at no cost to patients.

Documentation for PA Submission

Document Type What to Include Source
Prescriber Letter HAE diagnosis, attack history, rationale for Haegarda Provider on letterhead
Lab Results C4, C1-INH antigen/function, C1q if tested Laboratory reports
Training Completion Certificate or attestation of injection competency Training program
Prior Therapy Records Previous treatments tried and outcomes Medical records

Prior Authorization Process

Step-by-Step Submission

  1. Verify Coverage: Confirm patient's Humana enrollment and benefits
  2. Gather Documentation: Collect all required medical records and lab results
  3. Submit PA Request: Use Humana's provider portal (preferred method)
  4. Include Required Forms: "Request for Medicare Prescription Drug Coverage Determination"
  5. Follow Up: Track status and respond to any requests for additional information

Timeline Expectations

  • Standard Review: 7-30 days from complete submission
  • Expedited Review: 72 hours with documented medical urgency
  • Incomplete Submissions: May receive requests for additional information, extending timeline
Note: Submit complete documentation upfront to avoid delays. Incomplete submissions are a common cause of extended review times.

Alternative Submission Methods

If the provider portal isn't available:

  • Phone: 866-737-5113 for expedited requests
  • Fax: Contact Humana for current fax numbers (verify before sending)

When Humana Denies Coverage

Common Denial Reasons

Denial Reason How to Address
Insufficient HAE documentation Submit complete lab panel (C4, C1-INH, C1q)
Step therapy required Document failure/intolerance of preferred agents
Training not completed Provide training completion certificate
Frequency/dosing concerns Justify weight-based dosing (60 IU/kg twice weekly)
Not medically necessary Strengthen clinical rationale with attack frequency

Strengthening Your Case

When facing a denial, Counterforce Health helps patients and clinicians turn insurance denials into targeted, evidence-backed appeals. The platform identifies the specific denial basis and drafts point-by-point rebuttals aligned to Humana's own coverage policies.

For Haegarda appeals, focus on:

  • FDA-approved indication for HAE prophylaxis in patients ≥6 years
  • Clinical guidelines supporting C1-INH prophylaxis
  • Attack frequency and impact on quality of life
  • Training completion and patient's ability to self-administer

Appeals Process in North Carolina

Important: Medicare vs. Commercial Plans

North Carolina's Smart NC external review does NOT apply to Humana Medicare Advantage plans. These follow federal Medicare appeals processes instead.

Medicare Advantage Appeals Timeline

  1. Level 1 (Organization Review): File within 65 days of denial
  2. Level 2 (IRE Review): Automatic if Level 1 denied
  3. Federal External Review: Through CMS if previous levels unsuccessful

Required Steps for Medicare Appeals

  • Written Request: Submit appeal letter with denial notice
  • Supporting Documentation: Include all medical records and clinical justification
  • Expedited Option: Available for urgent medical situations
  • Deadline Tracking: Strict 65-day deadline from denial date
From Our Advocates: We've seen Haegarda appeals succeed when families include a detailed "day in the life" description of HAE's impact alongside clinical documentation. One family's appeal was approved after they documented their teenager missing 15+ school days due to unpredictable attacks, emphasizing how prophylaxis would restore normal activities.

For non-Medicare Humana plans, North Carolina residents can use Smart NC's external review process after exhausting internal appeals.

Cost Considerations and Support

Financial Assistance Options

  • HAEGARDA Connect: Patient support program offering copay assistance and training
  • CSL Behring Foundation: Grants for eligible patients with financial need
  • Medicare Part B Coverage: May apply for certain administration scenarios

Specialty Pharmacy Coordination

Once approved, Humana typically routes Haegarda through specialty pharmacy networks. Coordinate with:

  • CenterWell Specialty Pharmacy (Humana's preferred network)
  • Training scheduling for new patients
  • Reauthorization timeline (typically annual)

FAQ

How long does Humana's prior authorization take for Haegarda? Standard review takes 7-30 days. Expedited reviews (with documented urgency) are completed within 72 hours.

What if Haegarda isn't on my Humana formulary? Request a formulary exception with medical necessity documentation. Include clinical rationale for why covered alternatives aren't appropriate.

Can I appeal if my injection training isn't covered? Training is typically provided free through HAEGARDA Connect. If your plan denies training coverage, appeal as a necessary component of therapy.

Does step therapy apply if I've used Haegarda before? Previous successful use of Haegarda may support an exception to step therapy requirements. Document your treatment history and outcomes.

What's the difference between Medicare and commercial plan appeals in North Carolina? Medicare Advantage plans follow federal CMS appeals processes. Commercial plans may use North Carolina's Smart NC external review after internal appeals.

How often do I need reauthorization? Typically annually, though some plans may require more frequent reviews. Track your approval expiration date to avoid treatment interruptions.
