Aetna's Berinert Coverage Policy Overview

Plan Types and Coverage:

  • Commercial Plans: Subject to standard PA requirements and formulary restrictions
  • Medicare Advantage: Must also comply with CMS coverage policies
  • Aetna Better Health (Medicaid): State-specific pharmacy prior authorization guidelines apply

Prior authorization requests must be submitted electronically through Availity/NovoLogix at least two weeks before anticipated need.

Medical Necessity Requirements

Aetna considers Berinert medically necessary for acute hereditary angioedema attacks when all criteria are met:

Core Eligibility Criteria

1. Confirmed HAE Diagnosis

  • Documented hereditary angioedema with C1-INH deficiency
  • Low C4 levels and abnormal C1-INH (quantitative or functional)
  • Recurrent angioedema without urticaria
  • Poor response to antihistamines, steroids, and epinephrine

2. Specialist Involvement

  • Prescribed by or in consultation with allergist/immunologist, hematologist, or HAE specialist

3. FDA-Aligned Use

  • On-demand treatment of acute attacks (not routine prophylaxis)
  • Weight-based dosing: 20 units/kg IV per attack

4. Exclusion of Combination Therapy

  • Will not be used with other acute HAE medications for same attack

Step Therapy and Exceptions

Aetna's policy states that Berinert is considered medically necessary only when the member has contraindication, intolerance, or ineffective response to available preferred alternatives.

Required Documentation for Step Therapy Exception:

  • Trial and failure of preferred HAE agents (icatibant, other C1-INH products)
  • Contraindications to alternative therapies with clinical rationale
  • Intolerance with specific adverse reactions documented
  • Dates, doses, and outcomes of prior therapies
Tip: Include detailed attack logs showing inadequate response to preferred agents, including emergency department visits and severity scores.

Quantity and Frequency Limits

Standard Coverage Limits:

  • Per attack: 20 IU/kg per dose (one infusion per attack per FDA label)
  • Per 24 hours: Up to 2 doses for severe or persistent attacks
  • Monthly cap: Typically 2-4 treated attacks per month (4-8 standard doses)

Quantity Override Requirements:

For patients needing >2 severe attacks per month:

  • Attack frequency documentation over prior 3-6 months
  • Emergency department records and hospitalizations
  • Medical director review with supporting clinical justification
  • Weight-based dosing calculations for higher quantities

Required Diagnostic Documentation

Laboratory Requirements:

Test Expected Result ICD-10/CPT
C4 Level Low (often <30% normal) 86160
C1-INH Quantitative Low (Type I) or Normal/High (Type II) 86160
C1-INH Functional <40% activity 86161
C1q Normal (to exclude acquired deficiency) 86160

Diagnosis Code: D84.1 (Hereditary angioedema)

Clinical Documentation:

  • Attack history: Frequency, anatomical sites (laryngeal, facial, abdominal)
  • Family history: Hereditary pattern documentation
  • Prior treatments: Response to antihistamines, steroids, epinephrine
  • Emergency care: ICU stays, intubations related to HAE
Note: Submit actual lab reports with reference ranges, not just narrative descriptions.

Site of Care Requirements

Aetna CVS Specialty allows multiple administration settings with appropriate documentation:

Home Administration/Self-Infusion:

Requirements:

  • Prior authorization for both drug and site of care
  • Training documentation by healthcare professional
  • Patient competency verification for IV administration
  • Emergency action plan for laryngeal attacks
  • Stable venous access and appropriate home environment

Hospital Outpatient (requires justification):

Approved when:

  • History of severe hypersensitivity requiring hospital-level monitoring
  • Significant comorbidities making home infusion unsafe
  • Difficult IV access requiring hospital services
  • No available home infusion or ambulatory options

Evidence to Support Medical Necessity

Clinical Guidelines to Reference:

  • FDA prescribing information for acute HAE attacks
  • World Allergy Organization (WAO) HAE guidelines
  • Hereditary Angioedema Association clinical recommendations

Key Evidence Points:

  • Efficacy data: 20 IU/kg dose shortens time to relief vs. placebo
  • Safety profile: Established for on-demand use in clinical trials
  • Guideline support: Recommended as first-line therapy for acute attacks

Sample Medical Necessity Narrative

"Patient has confirmed Type I hereditary angioedema with documented C4 level of [X mg/dL] (normal 16-47) and C1-INH functional activity of [X%] (normal ≥68%). Despite trials of icatibant resulting in [specific outcome/adverse reaction], patient continues to experience severe abdominal and facial angioedema attacks requiring emergency care [X times in past 6 months]. Berinert 20 units/kg IV is medically necessary for on-demand treatment consistent with FDA labeling and WAO guidelines, as alternative therapies have proven ineffective/contraindicated due to [specific clinical reasons]."
