Aetna CVS Health Policy Overview

Aetna CVS Health requires prior authorization for all Takhzyro (lanadelumab) prescriptions across their commercial, Medicare, and Medicaid plans in Pennsylvania. The medication is processed through CVS Specialty Pharmacy and subject to quantity limits based on dosing intervals.

Plan Types and Coverage

Plan Type PA Required Formulary Status Specialty Pharmacy
Commercial HMO/PPO Yes Tier 3-4 Specialty CVS Specialty only
Medicare Part D Yes Non-preferred specialty CVS Specialty only
Medicaid (Aetna Better Health) Yes Prior authorization CVS Specialty only

All Takhzyro prescriptions must go through CVS Specialty Pharmacy—you cannot fill this medication at retail pharmacies. The 2025 precertification list confirms PA requirements for both 150mg/mL and 300mg/2mL formulations.

Medical Necessity Requirements

FDA-Approved Indication

Takhzyro is only covered for routine prophylaxis to prevent attacks of hereditary angioedema (HAE) in patients 2 years and older. Aetna will deny coverage for off-label uses like ACE-inhibitor induced angioedema or idiopathic angioedema.

Required Clinical Documentation

Your prescriber must submit documentation proving:

1. Confirmed HAE Diagnosis

  • Laboratory evidence of C1-inhibitor deficiency:
    • Type I HAE: Low C1-INH antigenic level AND low functional activity
    • Type II HAE: Normal/elevated C1-INH antigenic level BUT low functional activity
  • Low complement C4 level (supportive finding)
  • Genetic testing results if C1-INH levels are normal

2. Specialist Prescriber Requirement

  • Must be prescribed by or in consultation with an allergist or immunologist experienced in HAE management
  • General practitioners and other specialists typically require consultation notes

3. Attack History Documentation

  • Frequency and severity of HAE attacks
  • Impact on quality of life and daily activities
  • Emergency department visits or hospitalizations
  • Use of on-demand rescue medications
Tip: Keep a detailed attack diary including dates, locations affected (face, throat, abdomen), severity (1-10 scale), triggers, and treatments used. This documentation strengthens your PA request significantly.

Step Therapy and Exceptions

Required Prior Therapies

Aetna requires documented trial and failure of at least one alternative HAE prophylactic therapy before approving Takhzyro:

Alternative Documentation Required

Orladeyo (berotralstat oral) Duration of trial, adherence, effectiveness, side effects or contraindications

Medical Exception Pathways

You can bypass step therapy requirements if you have:

Documented Contraindications

  • Hypersensitivity to alternative medications
  • Inability to self-inject (for Haegarda)
  • Severe gastrointestinal issues preventing oral absorption (for Orladeyo)
  • Lack of IV access or infusion center availability (for Cinryze)

Prior Treatment Failures

  • Inadequate attack reduction (less than 50% improvement)
  • Severe adverse reactions requiring discontinuation
  • Non-adherence due to administration burden or side effects
