Prior Authorization Process

Step-by-Step: Fastest Path to Approval

  1. Confirm Diagnosis and Testing (Patient + Doctor)
    • Genetic testing confirming pathogenic TTR mutation
    • Clinical documentation of hATTR polyneuropathy symptoms
    • Timeline: 1-2 weeks for genetic results
  2. Complete REMS Enrollment (Doctor + Patient)
    • Provider enrolls in Tegsedi REMS program
    • Patient completes REMS education and consent
    • Timeline: 1-3 business days for processing
  3. Document Step Therapy (Doctor)
    • Records of failed/contraindicated first-line therapies (Onpattro, Amvuttra)
    • Clinical rationale if step therapy exception needed
    • Timeline: Immediate if records exist
  4. Submit Prior Authorization (Doctor)
    • Complete PA request via BCBSTX provider portal
    • Include all supporting documentation
    • Timeline: Same day submission
  5. BCBSTX Review (Insurance)
    • Standard review: 15 business days
    • Expedited review: 72 hours (if urgent)
    • Timeline: Varies by request type
  6. Specialty Pharmacy Coordination (Patient + Pharmacy)
    • Prescription sent to approved specialty pharmacy
    • Benefit verification and patient education
    • Timeline: 2-3 days for first shipment

Required Documentation Checklist

  • Genetic test results showing pathogenic TTR mutation
  • Clinical notes documenting hATTR polyneuropathy diagnosis
  • Treatment history with first-line therapies
  • REMS program enrollment confirmation
  • Baseline laboratory values (platelet count, kidney function)
  • Medical necessity letter from prescribing physician

REMS Program Requirements

The FDA requires both patients and prescribers to enroll in Tegsedi's Risk Evaluation and Mitigation Strategy (REMS) program due to serious safety risks.

Patient Requirements

  • Complete REMS education about thrombocytopenia and kidney risks
  • Sign informed consent acknowledging safety monitoring needs
  • Commit to required laboratory monitoring schedule

Prescriber Requirements

  • Complete REMS training and certification
  • Agree to monitor patients per protocol
  • Report adverse events as required

Ongoing Monitoring Schedule

  • Platelet counts: Weekly for first 8 weeks, then every 2 weeks
  • Kidney function: Every 2 weeks throughout treatment
  • Clinical assessments: Regular follow-up visits per prescriber judgment
Critical: Failure to maintain REMS compliance will result in therapy discontinuation and coverage termination.

Step Therapy and Medical Necessity

BCBSTX typically requires documented trial and failure of first-line hATTR treatments before approving Tegsedi.

Preferred First-Line Therapies

  1. Onpattro (patisiran) - siRNA therapy
  2. Amvuttra (vutrisiran) - newer siRNA option

Medical Necessity Criteria

Your doctor must document:

  • Confirmed hATTR amyloidosis with polyneuropathy
  • Inadequate response to preferred therapies after adequate trial
  • OR contraindications/intolerance to first-line options
  • Clinical rationale for Tegsedi specifically

Step Therapy Exception Requests

If you haven't tried first-line therapies, your doctor can request an exception by documenting:

  • Medical contraindications to preferred drugs
  • Previous severe adverse reactions
  • Clinical factors making Tegsedi the most appropriate choice

Specialty Pharmacy Requirements

BCBSTX requires Tegsedi to be dispensed only through their in-network specialty pharmacy network.

Why Specialty Pharmacy is Required

  • Complex handling and storage requirements
  • REMS program compliance monitoring
  • Patient education and injection training
  • Coordination with required laboratory monitoring

What to Expect

  • Benefit verification: Pharmacy confirms coverage and copay
  • Patient education: Training on injection technique and safety
  • Delivery coordination: Home delivery with temperature monitoring
  • Ongoing support: 24/7 pharmacist access for questions
Note: Attempting to fill Tegsedi at a retail pharmacy will result in coverage denial.

Understanding Costs and Coverage Gaps

Typical Cost Structure

  • Copay plans: Fixed amount per prescription (varies by tier)
  • Coinsurance plans: Percentage of drug cost (typically 10-40% for specialty drugs)
  • Deductible: May apply before copay/coinsurance kicks in

Financial Assistance Options

  1. Manufacturer Support: Limited programs available for legacy patients (verify with Ionis Connect)
  2. Foundation Grants: HealthWell Foundation, Patient Access Network Foundation
  3. State Programs: Texas may have additional assistance programs
Important: Government insurance (Medicare, Medicaid) typically cannot use manufacturer copay assistance programs.
