Set Your Goal: What Approval Requires

Your partnership with your HAE specialist is crucial for Haegarda approval. Aetna CVS Health requires prior authorization for this subcutaneous C1-esterase inhibitor, and success depends on thorough documentation of your HAE diagnosis and treatment history.

Core approval requirements include:

  • Confirmed HAE Type I or II diagnosis with laboratory evidence
  • Prescription from allergist, immunologist, or HAE specialist
  • Documentation of attack frequency and severity
  • Evidence that prophylaxis is medically necessary
  • Completed training plan for self-injection

Your doctor will need to demonstrate that Haegarda meets Aetna's specific criteria for long-term prophylaxis, which typically requires either severe monthly attacks, significant disability from HAE, or history of laryngeal involvement.

From our advocates: We've seen cases where patients brought detailed attack logs to their specialist appointments, which helped doctors write stronger medical necessity letters. One patient's three-month diary of missed work days and ER visits became the foundation for a successful authorization that was initially denied for "insufficient documentation."

Visit Prep: Documenting Your HAE Journey

Before your specialist appointment, gather comprehensive documentation of your HAE experience. This preparation ensures your doctor has everything needed for a strong authorization request.

Create a detailed symptom timeline:

  • Attack frequency over the past 6 months
  • Specific locations (face, throat, abdomen, extremities)
  • Duration of each episode
  • Triggers you've identified
  • Impact on daily activities, work, or school

Document all treatments tried:

  • On-demand medications (icatibant, ecallantide, C1-INH)
  • Previous prophylaxis attempts
  • Response to each treatment
  • Side effects or intolerance issues
  • Reasons for discontinuation

Functional impact notes:

  • Days of work/school missed
  • Emergency department visits
  • Hospitalizations or urgent care visits
  • Activities you've had to avoid
  • Quality of life impacts

This documentation helps your specialist understand the full scope of your condition and provides concrete evidence for medical necessity.

Evidence Kit: Labs, Guidelines, and Treatment History

Work with your doctor to compile a comprehensive evidence package that meets Aetna's documentation requirements.

Essential laboratory results:

  • C4 complement level (typically low in HAE)
  • C1-INH antigenic level
  • C1-INH functional level (<68% indicates deficiency)
  • C1q quantitative (to rule out acquired angioedema)

Clinical documentation:

  • Specialist consultation notes confirming HAE diagnosis
  • ICD-10 code D84.1 (Defects in the complement system)
  • Attack frequency records
  • Prior treatment responses

Published guidelines support: According to FDA labeling, Haegarda is indicated for routine prophylaxis to prevent HAE attacks in patients 6 years and older. Your specialist can reference this approval and relevant clinical studies demonstrating efficacy in reducing attack frequency.

Medication history summary: Your doctor should document any previous trials of other HAE medications, including specific reasons for failure or intolerance. This is particularly important if Aetna has step therapy requirements favoring other treatments first.

Medical Necessity Letter Structure

Your specialist's medical necessity letter is the cornerstone of your authorization request. Help ensure it includes all required elements by discussing these components during your visit.

Diagnosis section:

  • Clear statement of HAE Type I or II diagnosis
  • Specific laboratory values demonstrating C1-INH deficiency
  • Date of initial diagnosis and confirming specialist

Clinical rationale:

  • Current attack frequency and severity
  • Specific examples of recent episodes
  • Impact on patient function and quality of life
  • Why prophylaxis is necessary rather than on-demand treatment only

Treatment history:

  • Previous medications tried with specific outcomes
  • Reasons for treatment failures or discontinuation
  • Contraindications to alternative therapies

Haegarda-specific justification:

  • Why this particular medication is most appropriate
  • Dosing plan (typically 60 IU/kg twice weekly)
  • Monitoring strategy
  • Expected clinical outcomes

Risk assessment:

  • Consequences of delayed treatment
  • Potential for serious complications (airway involvement)
  • Impact of continued attacks on patient wellbeing

Supporting Your Doctor's Peer-to-Peer Review

If Aetna requests a peer-to-peer review, your preparation can help your doctor present the strongest possible case to the insurance medical reviewer.

Offer availability windows: Provide your specialist's office with your preferred times for the review call, as you may need to be available for additional questions about your experience.

Prepare a concise case summary: Help your doctor by organizing key points:

  • Most compelling recent attack examples
  • Specific functional limitations
  • Previous treatment failures with dates
  • Family history if relevant

Key talking points for your specialist:

  • Emphasize specialist qualifications (required by Aetna)
  • Highlight confirmed C1-INH deficiency with specific lab values
  • Document attack frequency meeting prophylaxis criteria
  • Explain why on-demand therapy alone is insufficient

Training documentation: Ensure your doctor can confirm that Haegarda Connect training has been arranged or completed, as this is often required for approval.

After-Visit Action Items

Following your specialist appointment, take specific steps to support the authorization process and maintain clear communication.

Document everything:

  • Save copies of all forms submitted
  • Keep records of submission dates and methods
  • Note reference numbers provided by Aetna
  • Track all communication with insurance

Portal messaging strategy: Use your healthcare system's patient portal to:

  • Confirm receipt of authorization submission
  • Request updates on processing status
  • Share any additional documentation requested by Aetna

Stay organized: Create a dedicated folder for all HAE-related insurance documents, including denial letters, appeal forms, and correspondence. This organization will be crucial if appeals become necessary.

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to draft point-by-point rebuttals aligned to each plan's specific rules. Their platform helps patients and clinicians navigate complex prior authorization requirements with payer-specific workflows and procedural compliance.

Respectful Persistence: Follow-Up Strategy

Maintain appropriate follow-up without overwhelming your healthcare team or insurance company.

Timeline expectations:

  • Initial authorization decisions: typically 5-7 business days
  • Expedited reviews (if urgent): 72 hours for most plans
  • Appeals processing: 30-45 days for standard appeals

Follow-up cadence:

  • Week 1: Confirm submission receipt
  • Week 2: Check processing status if no response
  • Week 3: Escalate if still pending without explanation

Escalation approach:

  • Start with your specialist's office for status updates
  • Contact Aetna member services if delays occur
  • Request supervisor involvement for unreasonable delays
  • Consider filing complaints with Pennsylvania Insurance Department if necessary

Professional communication: Always remain courteous and document all interactions. Frame follow-ups as seeking information rather than demanding action, which maintains positive relationships while ensuring progress.
