Set Your Goal: Understanding Humana's Requirements

Getting Firazyr (icatibant injection) approved by Humana requires meeting specific medical necessity criteria and navigating their prior authorization process. Here's what Humana expects:

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed
Prior Authorization Always required before coverage Complete PA submission via provider portal
HAE Diagnosis Confirmed hereditary angioedema Lab results: low C4, abnormal C1-INH levels
Specialist Prescription HAE specialist or consultation Allergist, immunologist, or hematologist
Attack Documentation History of acute episodes Attack diary, ER visits, severity records
Step Therapy May require other treatments first Documentation of failures/contraindications
Quantity Limits Typically 3 doses per attack/month Clinical justification for higher quantities
Specialty Pharmacy Must use CenterWell network Dispensing through Humana specialty pharmacy

Your partnership with your healthcare provider is crucial—they'll submit the prior authorization and provide the clinical documentation Humana requires for approval.

Visit Prep: Gathering Your Medical Evidence

Before meeting with your HAE specialist, prepare a comprehensive timeline of your condition and treatment history:

Symptom Timeline Checklist

  • Attack frequency: How often do episodes occur (weekly, monthly, seasonally)?
  • Severity patterns: Which body areas are affected (face, throat, abdomen, extremities)?
  • Trigger identification: Stress, trauma, medications, or unknown causes
  • Duration details: How long attacks typically last without treatment
  • Emergency care: Any ER visits, hospitalizations, or airway concerns

Previous Treatment Documentation

Document all therapies you've tried:

  • C1-INH concentrates (Berinert, Ruconest): effectiveness and access issues
  • Other acute treatments: ecallantide (Kalbitor), fresh frozen plasma
  • Prophylactic medications: if used, document outcomes and side effects
  • Antihistamines/steroids: lack of effectiveness (common in HAE)

Functional Impact Notes

Humana evaluates how HAE affects your daily life:

  • Work or school absences due to attacks
  • Limitations during episodes (eating, speaking, breathing)
  • Quality of life impact and anxiety about future attacks
  • Family history of HAE and genetic counseling results

Building Your Evidence Kit

Your specialist needs comprehensive documentation to support the prior authorization. Gather these materials in advance:

Laboratory Evidence

  • C4 complement levels: Should show consistently low values
  • C1-INH quantitative test: Measures protein amount (low in Type 1 HAE)
  • C1-INH functional assay: Measures protein activity (abnormal in Types 1 & 2)
  • Genetic testing results: If available, confirming HAE mutations

Clinical Documentation

  • Previous attack records: ER reports, urgent care visits, physician notes
  • Imaging studies: If attacks involved internal swelling or complications
  • Medication history: Prescription records showing failed treatments
  • Specialist consultation notes: From allergist, immunologist, or hematologist
