Coverage Requirements Overview

Aetna CVS Health covers Alprolix (eftrenonacog alfa) for hemophilia B under its specialty pharmacy benefit, but prior authorization is mandatory for all members. The medication is typically classified as a non-preferred specialty drug, requiring step therapy documentation in most cases.

Coverage Element Requirement Source
Prior Authorization Required for all plans Aetna 2025 Precertification List
Prescriber Board-certified hematologist Aetna Medical Policy
Dispensing CVS Specialty only CVS Caremark Network
Step Therapy Usually required Plan-specific formulary
Quantity Limits 50 IU/kg weekly or 100 IU/kg every 10 days FDA labeling

Medical Necessity Criteria

Aetna requires specific clinical criteria to establish medical necessity for Alprolix coverage:

Core Requirements

  • Confirmed hemophilia B diagnosis with genetic testing when available
  • Factor IX activity ≤2% of normal (documented within past 6 months)
  • Detailed bleeding history with frequency, severity, and impact documentation
  • Negative inhibitor screen (Bethesda assay <0.6 BU within 30 days)
  • Age 12 years or older for standard prophylaxis dosing
  • Board-certified hematologist prescription and ongoing management

Laboratory Requirements

  • Factor IX activity level (chromogenic or one-stage assay)
  • Complete blood count with platelet count ≥50,000/μL
  • Comprehensive metabolic panel
  • Liver function tests (ALT, AST within 2x upper normal limit)
  • Hepatitis B/C and HIV screening (negative for active infection)
Tip: Extended half-life factor products like Alprolix may affect some factor IX assays. Ensure your lab uses appropriate testing methods and timing relative to last dose.

Step Therapy and Preferred Products

Most Aetna plans require step therapy, meaning you must try preferred factor IX products before Alprolix approval. However, medical exceptions are available with proper documentation.

Typical Preferred Products

  • Standard half-life factor IX concentrates (BeneFIX, RIXUBIS)
  • Other extended half-life products may be preferred depending on plan

Medical Exception Pathways

You can bypass step therapy by documenting:

  • Previous failure of preferred products (inadequate bleeding control)
  • Intolerance or adverse reactions to preferred agents
  • Contraindications to preferred treatments
  • Clinical superiority of Alprolix for your specific situation

Required Documentation Checklist

Gather these documents before submitting your prior authorization:

Medical Records

  • Hemophilia B diagnosis confirmation
  • Factor IX activity lab results (within 6 months)
  • Bleeding diary or episode documentation
  • Previous treatment history and outcomes
  • Inhibitor testing results (within 30 days)
  • Complete blood count and chemistry panel

Clinical Documentation

  • Hematologist consultation notes
  • Treatment plan and dosing rationale
  • Prior therapy failure documentation (if applicable)
  • Medical necessity letter from prescriber

Reference FDA labeling and current hemophilia treatment guidelines from the World Federation of Hemophilia.

Common Denial Reasons and Solutions

Denial Reason Solution Strategy Required Documentation
Non-preferred product Submit medical exception request Prior therapy failure records, adverse reaction documentation
Insufficient bleeding history Provide detailed episode log Bleeding diary, emergency department records, hospitalization summaries
Dosing above limits Justify clinical need Pharmacokinetic data, breakthrough bleeding documentation
Missing hematologist involvement Ensure specialist prescription Board certification verification, consultation notes
Incomplete documentation Resubmit with all requirements Complete checklist verification
