Before You Start: Plan Verification

Confirm Your Coverage Details

Verify REMS Certification Requirements

All vigabatrin prescribing requires enrollment in the Vigabatrin REMS Program. This shared system applies to both generic vigabatrin and brand Sabril due to the risk of permanent vision loss.

Three-party certification needed:

  1. Prescriber must complete training and certification
  2. Patient/guardian must sign consent forms acknowledging vision risks
  3. Pharmacy must be REMS-certified to dispense

Gather Required Documentation

Medical Records Checklist

Essential documents for your PA submission:

  • Diagnosis with ICD-10 codes
    • Infantile spasms: G40.822 (epileptic spasms)
    • Refractory seizures: G40.919 (epilepsy, unspecified, not intractable)
  • Prior medication history showing failures/intolerances
    • For infantile spasms: Document ACTH trial if attempted
    • For refractory seizures: Evidence of ≥2-3 failed AEDs (carbamazepine, valproic acid, levetiracetam, topiramate)
  • Baseline vision assessment (required by FDA labeling)
  • Current medication list with dosing
  • Recent clinic notes from neurologist/epileptologist
  • EEG reports confirming seizure type
  • REMS enrollment confirmations for all parties

Clinician Corner: Medical Necessity Letter

Key elements your neurologist should include:

  1. Patient presentation: Age, seizure type, frequency, impact on development/function
  2. Prior treatments: Specific medications tried, doses, duration, reasons for discontinuation
  3. Clinical rationale: Why vigabatrin is appropriate for this patient's condition
  4. Monitoring plan: Vision testing schedule, seizure tracking, safety assessments
  5. Guideline support: Reference to FDA labeling for approved indications

Sample language: "Patient has refractory complex partial seizures with inadequate response to therapeutic trials of levetiracetam (2000mg daily × 3 months) and carbamazepine (800mg daily × 4 months), discontinued due to persistent breakthrough seizures. Vigabatrin is FDA-approved for this indication and represents appropriate next-line therapy per current epilepsy guidelines."

Frequently Asked Questions

How long does Florida Blue prior authorization take for vigabatrin? Standard requests: 7-30 days. Expedited requests for urgent cases: 24-72 hours. Medicare Part D plans have a 7-day standard timeline.

What if vigabatrin isn't on my formulary? You can request a formulary exception with medical necessity documentation. Include evidence that covered alternatives have failed or are contraindicated.

Can I get expedited approval for pediatric seizures? Yes, frequent seizures affecting a child's development qualify for expedited review. Include documentation of seizure frequency and developmental impact.

Do I need a neurologist to prescribe vigabatrin? While not always required, specialist involvement strengthens your PA request. Epileptologists are most familiar with REMS requirements and monitoring protocols.

What happens if my pharmacy isn't REMS-certified? Vigabatrin cannot be dispensed from non-certified pharmacies. Use the REMS website to find certified options or ask your pharmacy to complete certification.

How often do I need vision testing? FDA labeling requires baseline testing before starting vigabatrin, then every 3 months during treatment, with post-discontinuation follow-up.

What if I move to another state during treatment? REMS certification transfers, but you'll need to verify your new state's Blue Cross Blue Shield plan coverage and potentially re-submit PA documentation.

Can I appeal directly to the state if denied? Yes, Florida offers external review through the Department of Financial Services after exhausting internal appeals. This independent review is free and can overturn insurer denials.
