Work With Your Doctor to Get Haegarda (C1-Esterase Inhibitor) Approved by UnitedHealthcare in California

Quick Answer: Getting Haegarda Covered by UnitedHealthcare in California

Haegarda requires prior authorization from UnitedHealthcare for hereditary angioedema (HAE) prophylaxis in California. Your best path: gather HAE diagnosis documentation (C4, C1-INH functional/quantitative levels), work with an HAE specialist to submit a complete prior authorization request, and be prepared for potential step therapy requirements favoring lanadelumab first. If denied, California's Independent Medical Review (IMR) system overturns about 55-61% of medical necessity denials. Start today: call your doctor's office to request your lab results and schedule a consultation to discuss prophylaxis options.

Set Your Goal: Understanding UnitedHealthcare's Requirements

UnitedHealthcare requires prior authorization for Haegarda with specific medical necessity criteria that you and your doctor must address together. Here's what approval requires:

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed Source
Confirmed HAE diagnosis Type I/II HAE or HAE with normal C1-INH Lab results showing low C4, abnormal C1-INH levels/function UHC Policy
Age requirement 6 years or older Medical records confirming age UHC Policy
Prophylaxis use only Prevention of attacks, not acute treatment Clinical notes documenting prophylactic intent UHC Policy
Specialist prescriber Allergist, immunologist, or hematologist Provider credentials on file UHC Policy
No combination therapy Cannot use with other HAE prophylaxis drugs Attestation of single-agent use UHC Policy

Step Therapy Considerations

Important: UnitedHealthcare often requires patients to try lanadelumab (Takhzyro) before approving Haegarda. Be prepared to document why lanadelumab isn't appropriate or has failed if you've tried it previously.

Visit Preparation: Building Your Clinical Case

Before meeting with your HAE specialist, gather this information to strengthen your case:

Symptom Timeline Documentation

Create a detailed log including:

  • Attack frequency: How often you experience HAE episodes (weekly, monthly)
  • Attack severity: Impact on daily activities, emergency room visits, hospitalizations
  • Triggers identified: Known factors that precipitate attacks
  • Current management: On-demand medications used and their effectiveness

Previous Treatment History

Document all HAE treatments you've tried:

  • On-demand therapies: Icatibant, ecallantide, C1-INH for acute attacks
  • Previous prophylaxis attempts: Lanadelumab, berotralstat, androgens, antifibrinolytics
  • Reasons for discontinuation: Lack of efficacy, side effects, contraindications
  • Response to treatment: Specific outcomes and timeframes

Functional Impact Assessment

Prepare to discuss:

  • Work or school days missed due to HAE attacks
  • Activities you avoid due to fear of attacks
  • Quality of life impact on you and your family
  • Psychological effects of unpredictable attacks

Evidence Kit: Essential Documentation

Work with your doctor's office to compile these critical documents:

Laboratory Evidence

Required HAE diagnostic tests:

  • C4 level: Usually low in HAE types I and II
  • C1-INH quantitative (antigenic) level: Low in type I, normal/elevated in type II
  • C1-INH functional assay: Reduced in both type I and II HAE
Tip: Request copies of actual lab reports with reference ranges, not just summaries. UnitedHealthcare reviewers need to see specific values and lab interpretations.

Clinical Documentation

  • Specialist consultation notes from allergist, immunologist, or hematologist
  • Family history documentation if available (HAE can be inherited)
  • Emergency department records from HAE attacks
  • Imaging or other tests that support your diagnosis

Treatment History Records

  • Medication trial documentation with dates, dosages, and outcomes
  • Allergy or contraindication notes for alternative therapies
  • Response assessments showing inadequate control with current management

Letter of Medical Necessity Structure

Your specialist will need to write a comprehensive letter addressing these key elements:

Essential Components

  1. Patient identification and diagnosis
    • Confirmed HAE type with supporting lab values
    • ICD-10 diagnosis code (typically D84.1 for HAE)
  2. Clinical rationale for Haegarda
    • Attack frequency and severity despite current management
    • Why Haegarda is medically necessary for this patient
    • Specific dosing plan (up to 60 IU/kg subcutaneously, twice weekly maximum)
  3. Previous treatment failures or contraindications
    • Documented trials of alternative therapies
    • Specific reasons other options aren't suitable
  4. Risk of treatment delay
    • Potential for life-threatening laryngeal attacks
    • Impact on patient's ability to function normally
  5. Supporting references
    • FDA approval for HAE prophylaxis
    • Published clinical trial data
    • Professional society guidelines

When Counterforce Health helps healthcare providers with prior authorization letters, they ensure each element is thoroughly documented with evidence-based citations tailored to the specific payer's requirements.

Peer-to-Peer Review Support

If UnitedHealthcare requests a peer-to-peer review, help your doctor prepare by:

Scheduling Coordination

  • Provide availability windows: Give your doctor's office multiple time slots when the physician can take the call
  • Confirm contact information: Ensure UnitedHealthcare has current phone numbers
  • Request advance notice: Ask for at least 24-48 hours' notice when possible

Case Summary Preparation

Help your doctor create a concise summary including:

  • 30-second elevator pitch: Why you need Haegarda specifically
  • Key lab values: C1-INH levels and functional assay results
  • Treatment history: What you've tried and why it didn't work
  • Clinical urgency: Risk of continued attacks without prophylaxis

Key Talking Points

Your doctor should emphasize:

  • Confirmed HAE diagnosis with specific lab abnormalities
  • Inadequate control with current management
  • Specialist recommendation for prophylactic therapy
  • Patient-specific factors that make Haegarda the best choice

After-Visit Documentation

After your appointment, ensure proper documentation and follow-up:

Save Everything

  • Copies of all forms submitted to UnitedHealthcare
  • Prior authorization reference numbers and submission dates
  • Contact information for the UnitedHealthcare pharmacy department
  • Timeline expectations provided by your doctor's office

Portal Communication

Use your healthcare provider's patient portal to:

  • Follow up on submission status without calling the office
  • Request updates on prior authorization decisions
  • Share additional information if requested by UnitedHealthcare

Insurance Communication

  • Monitor your UnitedHealthcare member portal for updates
  • Save all correspondence including emails and letters
  • Document phone calls with date, time, and representative name

Respectful Persistence and Follow-Up

Appropriate Follow-Up Cadence

  • Week 1: Confirm submission and reference number
  • Week 2: Check status if no response received
  • Week 3: Escalate if still pending without explanation
  • After denial: Begin appeal process immediately

How to Escalate Politely

When calling your doctor's office:

  • Acknowledge their workload: "I know you're busy, but could you help me check..."
  • Be specific: "The prior auth was submitted on [date] with reference [number]"
  • Offer to help: "Is there anything I can gather to support the request?"

Working with Office Staff

  • Build relationships with prior authorization coordinators
  • Provide your contact information for quick questions
  • Be available to provide additional information promptly

California Appeals Process

If UnitedHealthcare denies coverage, California offers strong appeal rights:

Internal Appeals (First Step)

  • Timeline: Must file within 180 days of denial
  • Process: Submit through UnitedHealthcare member portal or by mail
  • Documentation: Include all supporting medical records
  • Decision timeframe: 30 days for standard appeals, 72 hours for urgent

Independent Medical Review (IMR)

California's external review system has favorable success rates:

  • Eligibility: Available after internal appeal completion or 30-day wait
  • Success rate: Approximately 55-61% of medical necessity denials are overturned
  • Timeline: 30 days for standard review, 7 days for expedited
  • Cost: Free to patients
  • Contact: DMHC Help Center at 888-466-2219
From Our Advocates: We've seen several California patients successfully overturn Haegarda denials through IMR by submitting comprehensive attack logs, specialist letters emphasizing the life-threatening nature of laryngeal attacks, and evidence that less expensive alternatives were ineffective. The key was demonstrating that prophylaxis was medically necessary to prevent emergency situations.

Required Documentation for Appeals

  • Original denial letter from UnitedHealthcare
  • Updated medical necessity letter from your specialist
  • Complete medical records including lab results and treatment history
  • Patient impact statement describing functional limitations

Common Denial Reasons & Solutions

Denial Reason How to Address Documentation Needed

FAQ

How long does UnitedHealthcare prior authorization take for Haegarda in California? Standard prior authorization decisions are typically made within 14 business days. Urgent requests may be processed within 72 hours if clinical urgency is documented.

What if Haegarda is not on my UnitedHealthcare formulary? Haegarda requires prior authorization on most UnitedHealthcare plans but is generally covered when medical necessity criteria are met. Non-formulary status doesn't prevent coverage with proper documentation.

Can I request an expedited appeal if denied? Yes, if your doctor documents that delays in treatment could seriously jeopardize your health. California requires expedited appeals to be processed within 72 hours for urgent situations.

Does step therapy apply if I tried lanadelumab outside California? Treatment history from any state should count toward step therapy requirements. Ensure your California provider has complete records of previous trials and outcomes.

What happens if UnitedHealthcare delays my prior authorization decision? In California, you can file a complaint with the DMHC if your health plan doesn't meet required decision timeframes. Contact the DMHC Help Center at 888-466-2219.

How much does Haegarda cost without insurance coverage? Retail prices vary by dosage but typically range in the high four to five figures monthly before insurance. Patient assistance programs may help reduce costs while pursuing coverage.

Can I use Haegarda for acute HAE attacks? No, Haegarda is FDA-approved only for prophylaxis (prevention) of HAE attacks. It's not indicated for treating acute episodes.

What if my employer health plan has different rules? Self-funded employer plans (ERISA) may have different appeal processes than standard UnitedHealthcare policies. Check your Summary Plan Description for specific procedures.
