Before you begin, gather:

  • Insurance card and member ID
  • Complete HAE diagnosis documentation
  • Lab results (C4, C1-INH functional and antigenic levels)
  • Attack frequency logs from the past 6-12 months
  • List of previous HAE treatments tried and outcomes

Eligibility Triage: Do You Qualify?

Likely Eligible ✅

  • Confirmed HAE diagnosis with C1-INH deficiency (low functional level <50% or low antigenic level)
  • Age 6 or older (FDA indication requirement)
  • Specialist involvement (allergist, immunologist, or HAE expert)
  • Attack frequency requiring prophylaxis (typically ≥1 attack per month)
  • Previous therapy documentation (if step therapy applies)

Possibly Eligible ⚠️

  • Normal C1-INH levels but suspected HAE with normal C1-INH (requires genetic testing)
  • Incomplete diagnosis workup (missing functional or antigenic C1-INH testing)
  • Limited attack history but severe symptoms
  • No specialist consultation yet

Not Yet Eligible ❌

  • No confirmed HAE diagnosis
  • Under age 6

  • Other causes of angioedema not ruled out (ACE inhibitor-induced, etc.)

If Likely Eligible: Document Checklist

Your HAE specialist should submit these documents with the prior authorization:

Required Clinical Documentation

  • C1-INH functional assay results showing <50% activity
  • C1-INH antigenic level (low in Type I HAE, normal/elevated in Type II)
  • C4 level (typically low in both HAE types)
  • Attack frequency log with dates, severity, and anatomical locations
  • Previous treatment history including failures or intolerances
  • Current weight for dosing calculations (60 IU/kg twice weekly)

Administrative Requirements

Tip: Aetna requires prescriber attestation that Haegarda won't be used with other HAE prophylaxis medications. Include this statement in your submission.

Submission path: Most Haegarda prescriptions go through CVS Specialty Pharmacy. Your specialist can fax the complete PA packet or submit through Aetna's provider portal.

If Possibly Eligible: Tests to Request

Ask your doctor to order:

  1. Complete HAE panel if not done:
    • C4 level
    • C1-INH functional assay
    • C1-INH antigenic level
  2. Genetic testing if C1-INH levels are normal but HAE suspected:
    • SERPING1 gene mutations
    • F12, ANGPT1, PLG, KNG1, HS3ST6, MYOF genes
  3. Family history documentation if genetic testing is positive

Timeline to re-apply: Allow 2-4 weeks for lab results, then resubmit PA with complete documentation.

If Not Yet Eligible: Alternatives

Discuss these options with your specialist:

  • Oral options: Berotralstat (Orladeyo) may have different coverage criteria
  • IV prophylaxis: Cinryze (IV C1-INH) for patients who can't self-inject
  • On-demand therapy: Icatibant (Firazyr) or ecallantide (Kalbitor) for acute attacks

Prepare for exception requests: Document why alternatives aren't suitable (contraindications, access issues, previous failures).

From our advocates: We've seen successful appeals when families included detailed attack logs showing frequency, severity, and impact on daily activities. One composite case involved a teenager whose school attendance improved dramatically after approval—the concrete functional improvement data helped convince the external reviewer that prophylaxis was medically necessary over on-demand treatment alone.

For self-funded employer plans: ERISA rules may apply instead of Ohio external review. Contact your HR department to confirm your plan type and appeal rights.

FAQ

How long does Aetna prior authorization take for Haegarda? Standard PA decisions typically take 30-45 days. Expedited reviews (when delay could jeopardize health) are decided within 72 hours.

What if Haegarda is non-formulary on my plan? You can request a formulary exception with medical necessity documentation. Include evidence that formulary alternatives (like lanadelumab or berotralstat) aren't appropriate for your case.

Can I request an expedited appeal in Ohio? Yes, both internal appeals with Aetna and external reviews through Ohio DOI offer expedited timelines (72 hours) when your prescriber certifies that delay could seriously harm your health.

Does step therapy apply if I've failed treatments outside Ohio? Treatment history from any location should count toward step therapy requirements. Include complete documentation of previous therapies, dates tried, and reasons for discontinuation.

How much does Haegarda cost without insurance? Retail cost varies by vial strength and quantity but typically ranges in the high four to five figures monthly. Haegarda Connect offers patient assistance programs and copay support.

What's the difference between functional and antigenic C1-INH testing? Functional testing measures how well the protein works; antigenic testing measures how much protein is present. HAE Type I has low levels of both, while Type II has normal/high antigenic levels but low functional activity.

Can pharmacists help with prior authorization? CVS Specialty Pharmacy (Aetna's specialty pharmacy) can assist with PA submission and follow-up, but the prescriber must provide clinical documentation and medical necessity rationale.
