Set Your Goal: What Approval Requires

Aetna CVS Health requires specific criteria for Haegarda coverage. Understanding these upfront helps you and your provider build the strongest case from day one.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Confirmed HAE diagnosis Lab evidence of C1-INH deficiency/dysfunction Aetna medical policy
Age ≥6 years FDA indication minimum FDA prescribing information
Specialist involvement Allergist, immunologist, or HAE-experienced physician Aetna prior authorization form
Prophylaxis indication Prevention of attacks, not acute treatment Medical necessity documentation
No concurrent HAE prophylaxis Cannot use with Takhzyro or other preventive agents Aetna formulary policy

Your Partnership Strategy

Work with your provider to position Haegarda as medically necessary rather than just convenient. This means documenting:

  • Frequency and severity of HAE attacks before treatment
  • Impact on daily functioning and quality of life
  • Previous treatments tried and why they failed or weren't tolerated
  • Clinical rationale for subcutaneous C1-INH specifically
Tip: Aetna doesn't require step therapy between Haegarda and Takhzyro, so either can be first-line if criteria are met.

Visit Prep: Document Your HAE Journey

Before your appointment, create a comprehensive timeline that your provider can use in the prior authorization and medical necessity letter.

Essential Information to Gather

Symptom Timeline:

  • When did HAE symptoms first appear?
  • How often do you experience attacks (per month/year)?
  • Which body parts are typically affected?
  • How long do attacks typically last?
  • What triggers have you identified?

Treatment History:

  • List every HAE medication tried (including dates and duration)
  • Document why each treatment was discontinued (ineffective, side effects, access issues)
  • Include on-demand treatments used and their effectiveness
  • Note any hospitalizations or ER visits for HAE attacks

Functional Impact:

  • Days of work/school missed due to HAE
  • Activities you've had to avoid or modify
  • Impact on family members or caregivers
  • Any psychological effects (anxiety about attacks, etc.)

Laboratory Results to Request

Your provider will need recent lab confirmation of HAE. Request copies of:

  • C4 complement level (should be low in HAE)
  • C1-INH antigenic level (low in Type I HAE, normal/elevated in Type II)
  • C1-INH functional assay (low in both Type I and II HAE)
  • C1q level (normal in hereditary HAE, helps rule out acquired forms)

If you don't have recent labs, ask your provider to order the hereditary angioedema panel to confirm diagnosis.

Evidence Kit: Labs, Guidelines, and History

Your provider needs clinical evidence beyond just your symptoms. Help them compile a comprehensive evidence package.

Published Guidelines to Reference

Your medical necessity letter should cite established treatment guidelines:

  • FDA prescribing information for Haegarda's approved indication
  • World Allergy Organization (WAO) guidelines for HAE management
  • American Academy of Allergy, Asthma & Immunology (AAAAI) position statements

Medication History Summary

Create a one-page summary of your HAE treatment journey:

Format:

Previous HAE Treatments:
1. [Medication name] - [Dates used] - [Outcome/reason for discontinuation]
2. [On-demand treatments] - [Frequency of use] - [Effectiveness rating]
3. [Any other prophylactic attempts] - [Duration] - [Results]

Current situation:
- Attack frequency: [X attacks per month]
- Severity: [Describe typical attack]
- Impact: [Days missed work/activities]

Medical Necessity Letter Structure

The medical necessity letter is crucial for approval. Here's the structure your provider should follow:

Clinician Corner: Medical Necessity Checklist

For Healthcare Providers: Your letter should include these key elements in order:

1. Patient Demographics and Diagnosis

  • Clear statement of HAE Type I or II diagnosis
  • Date of diagnosis and confirming physician
  • Laboratory evidence with specific values and dates

2. Clinical Rationale for Haegarda

  • Current attack frequency and severity
  • Impact on patient's daily functioning
  • Why subcutaneous C1-INH is appropriate for this patient
  • Age appropriateness (≥6 years for Haegarda)

3. Previous Treatment History

  • Detailed list of prior HAE therapies tried
  • Specific reasons for discontinuation or inadequacy
  • Documentation of treatment failures or intolerance

4. Risks of Delayed Treatment

  • Potential for increased attack frequency
  • Risk of laryngeal edema and airway compromise
  • Impact on quality of life and productivity

5. Supporting References

Peer-to-Peer Support Strategy

If the initial prior authorization is denied, Aetna often offers peer-to-peer review where your provider can speak directly with their medical director.

How to Support Your Provider

Offer Availability Windows:

  • Provide your provider with your schedule for urgent calls
  • Be available to clarify symptoms or treatment history during the call

Prepare a Concise Case Summary:

Patient: [Age] with confirmed HAE Type [I/II]
Current status: [X] attacks per month, [impact description]
Previous treatments: [Brief list with outcomes]
Request: Haegarda for prophylaxis per FDA indication
Key point: [Most compelling reason for approval]

Gather Supporting Documentation:

  • Recent attack diary or calendar
  • Photos of swelling (if appropriate and consented)
  • Work/school absence documentation

After-Visit Documentation

Proper documentation after your appointment ensures nothing gets lost in the approval process.

What to Save

  • Copy of the prior authorization submission
  • Medical necessity letter (request a copy for your records)
  • All supporting lab results and clinical notes
  • Confirmation of submission (reference number, date, method)

Portal Communication Tips

When messaging your provider through the patient portal:

  • Be specific: "Following up on Haegarda PA submitted [date]"
  • Include reference numbers: "PA reference #12345"
  • Ask for updates: "What's the expected timeline for a decision?"
  • Offer help: "Happy to provide additional information if needed"

Respectful Persistence and Escalation

Insurance approvals take time, but knowing when and how to follow up keeps your case moving.

Follow-Up Cadence

Week 1-2: Allow processing time, no follow-up needed Week 3: Check status through Aetna member services Week 4: Contact your provider's office for updates Week 5+: Consider escalation if no decision received

How to Escalate Politely

With Your Provider:

  • "I understand these things take time. Is there anything I can do to help move this along?"
  • "Would it be helpful if I contacted Aetna directly to check on the status?"

With Aetna:

  • "I'm calling to check on the status of prior authorization request #[number]"
  • "My condition requires prompt treatment. Is there an expedited review process?"

FAQ

How long does Aetna CVS Health prior authorization take in North Carolina? Standard PA decisions typically take 14-30 days. Urgent requests must be decided within 72 hours. You can check status through the Aetna member portal or by calling member services.

What if Haegarda is non-formulary on my plan? You can request a formulary exception by demonstrating medical necessity and providing evidence that formulary alternatives are inappropriate or ineffective for your specific situation.

Can I request an expedited appeal in North Carolina? Yes, both Aetna and Smart NC offer expedited reviews when delays could seriously jeopardize your health. Your provider must document the urgency and potential harm from delayed treatment.

Does step therapy apply if I haven't tried other HAE medications? Aetna's current policy doesn't require step therapy between Haegarda and Takhzyro. However, they may require documentation of why Haegarda is preferred over other available options.

What if I'm traveling and need treatment while my appeal is pending? Contact Aetna's 24/7 member services for emergency coverage authorization. Keep documentation of any out-of-pocket costs for potential reimbursement if your appeal succeeds.

How much does Haegarda cost without insurance? Retail cost per vial typically ranges in the high four to five figures. Total monthly costs vary based on weight-based dosing. CSL Behring's Haegarda Connect program offers copay assistance for eligible commercially-insured patients.

From our advocates: We've seen many HAE patients succeed with Aetna appeals by focusing on functional impact rather than just attack frequency. One patient documented how unpredictable swelling episodes prevented them from traveling for work, ultimately convincing the reviewer that prophylaxis was essential for maintaining employment. The key was specific, measurable examples rather than general statements about quality of life.
