Visit Prep: What to Bring Your Doctor

Schedule a dedicated appointment to focus on your Takhzyro prior authorization. Come prepared with:

Symptom Timeline Documentation

  • Attack diary with dates, locations (face, throat, abdomen), duration, and triggers
  • Emergency room visits related to HAE attacks
  • Missed work/school days due to HAE symptoms
  • Functional impact on daily activities, relationships, and quality of life

Previous Treatment Records

  • Current medications for HAE (on-demand and prophylactic)
  • Past therapies tried including C1 esterase inhibitors, icatibant, ecallantide
  • Reasons for discontinuation (inadequate response, side effects, contraindications)
  • Dosing history and any adjustments made

Diagnostic Information

  • Laboratory results confirming HAE diagnosis:
    • Low C4 levels
    • Decreased C1-INH functional activity (<50%)
    • C1-INH antigenic levels (low in Type 1, normal/high in Type 2)
  • Genetic testing results if performed
  • Specialist consultation notes from allergist/immunologist
Tip: Create a one-page summary of your HAE journey including diagnosis date, key lab values, major attacks, and treatment failures. This helps your doctor quickly understand your case complexity.

Building Your Evidence Kit

Your physician needs specific documentation to build a compelling case for Takhzyro approval:

Required Clinical Evidence

  1. HAE Diagnosis Confirmation
    • Lab reports with abnormal C4 and C1-INH levels
    • ICD-10 diagnosis code D84.1 (Defects in the complement system)
    • Clinical notes describing HAE symptoms and family history
  2. Attack Documentation
    • Minimum 6-month attack log showing frequency and severity
    • Evidence of unpredictable, recurrent angioedema episodes
    • Documentation of attacks affecting face, throat, or abdomen
  3. Treatment History
    • Prior use of on-demand therapies (icatibant, ecallantide, C1-INH)
    • Previous prophylactic treatments and outcomes
    • Reasons for treatment changes or failures

Supporting Guidelines and References

Your doctor should reference these evidence sources in the medical necessity letter:

  • FDA approval for HAE prophylaxis in patients ≥2 years
  • World Allergy Organization (WAO) guidelines for HAE management
  • American Academy of Allergy, Asthma & Immunology (AAAAI) practice parameters
  • Published clinical trials demonstrating Takhzyro efficacy

Letter of Medical Necessity Structure

Work with your physician to ensure the medical necessity letter includes these key components:

Essential Elements Checklist

  • Patient identification (name, DOB, policy number)
  • Provider credentials and letterhead
  • HAE diagnosis with supporting lab values
  • Attack frequency and severity documentation
  • Prior treatment history and outcomes
  • Clinical rationale for Takhzyro specifically
  • Expected treatment goals and monitoring plan
  • FDA indication reference and dosing rationale

Clinical Rationale Framework

Your doctor should address:

  1. Why Takhzyro is necessary for your specific case
  2. How previous treatments failed or were inadequate
  3. Expected benefits (attack reduction, improved quality of life)
  4. Monitoring plan and follow-up schedule
From our advocates: We've seen strong approvals when physicians include specific attack reduction goals (e.g., "reduce attacks by ≥50%" or "eliminate laryngeal episodes") and reference the patient's individual risk factors that make prophylaxis medically necessary.

Peer-to-Peer Review Support

Availability Windows

  • Offer multiple time slots when your doctor can take the call
  • Morning slots often work better for busy specialists

Case Summary Preparation

Help your physician create a concise 2-minute summary covering:

  • HAE diagnosis with key lab values
  • Attack pattern and severity
  • Treatment failures and contraindications
  • Specific benefits expected from Takhzyro
