Set Your Goal: What Approval Requires

Humana requires prior authorization for vigabatrin across most Medicare Advantage and Part D plans. Your neurologist must demonstrate:

  • Appropriate diagnosis: Infantile spasms (1 month-2 years) or refractory complex partial seizures (≥2 years)
  • Failed alternatives: Documentation of inadequate response to other antiseizure medications
  • REMS compliance: Enrollment in the Vigabatrin REMS program with baseline vision testing
  • Specialist involvement: Prescription from or consultation with a pediatric neurologist/epileptologist
Note: Generic vigabatrin and brand Sabril both require the same prior authorization process and REMS enrollment.

Your role: Provide complete treatment history, gather supporting documents, and advocate alongside your provider. Provider's role: Submit clinical justification, ensure REMS compliance, and handle peer-to-peer reviews if needed.

Visit Prep: Building Your Case

Before your appointment, create a comprehensive timeline of your seizure history and treatments. This preparation strengthens your provider's ability to write a compelling medical necessity letter.

Symptom Timeline

Document:

  • Seizure onset: Age, initial presentation, triggers
  • Seizure description: Type, frequency, duration, impact on daily life
  • EEG findings: Hypsarrhythmia (for infantile spasms), focal abnormalities
  • Functional impact: Developmental regression, injuries, quality of life changes

Treatments Tried and Failed

For each medication, note:

  • Drug name and dose: Include maximum tolerated dose
  • Duration of trial: How long you tried each medication
  • Reason for discontinuation: Lack of efficacy, side effects, or contraindications
  • Specific outcomes: Percentage seizure reduction, side effects experienced
Tip: Include non-medication treatments like ketogenic diet, VNS, or epilepsy surgery if applicable.

Functional Impact Notes

Prepare specific examples:

  • For infantile spasms: Loss of milestones, feeding difficulties, sleep disruption
  • For refractory seizures: School/work absences, driving restrictions, injury risk
  • Caregiver burden: Family stress, financial impact, care coordination needs

Evidence Kit: Clinical Documentation

Gather these documents before your visit to support your provider's submission:

Essential Records

  • Insurance card and policy details: Verify Humana plan type (Medicare Advantage vs. Part D)
  • Complete medication list: Current and past antiseizure medications with dates
  • Recent EEG reports: Showing seizure patterns or treatment response
  • Imaging studies: MRI, CT scans relevant to seizure diagnosis
  • Laboratory results: Baseline labs, drug levels, genetic testing if applicable

Supporting Documentation

  • Seizure diary: Frequency, triggers, patterns over recent months
  • School/work records: Documenting functional impact and absences
  • Emergency department visits: Related to seizures or medication side effects
  • Specialist consultations: Notes from neurologists, epileptologists, or other specialists

Counterforce Health helps patients and providers streamline this documentation process by automatically identifying denial reasons and drafting targeted appeals with the right clinical evidence and payer-specific requirements.

Medical Necessity Letter Structure

Your neurologist's medical necessity letter should follow this proven framework:

1. Clinical Summary

  • Patient demographics: Age, weight, relevant medical history
  • Diagnosis with ICD-10: Infantile spasms (G40.4) or focal epilepsy codes
  • Current seizure status: Frequency, severity, functional impact

2. Treatment History

  • Chronological list: All antiseizure medications tried with doses and outcomes
  • Specific failures: "Patient failed levetiracetam 60 mg/kg/day due to behavioral side effects"
  • Contraindications: Medical reasons certain alternatives cannot be used

3. Clinical Rationale for Vigabatrin

  • FDA indication match: Specify infantile spasms (monotherapy) or refractory CPS (adjunctive)
  • Mechanism advantage: Unique GABA-transaminase inhibition not previously tried
  • Evidence base: Reference clinical trials and guidelines supporting use

4. Safety and Monitoring Plan

  • REMS compliance: Document prescriber certification and patient enrollment
  • Vision monitoring: Baseline exam completed, follow-up schedule established
  • Risk-benefit assessment: Why benefits outweigh vision loss risk for this patient

Key Clinical References

Your provider can cite these evidence sources:

  • FDA prescribing information for approved indications
  • International League Against Epilepsy guidelines for infantile spasms
  • Tuberous Sclerosis Complex consensus recommendations for TSC-related spasms

Peer-to-Peer Support

If Humana requests a peer-to-peer review, help your provider prepare:

Offer Availability Windows

  • Flexible scheduling: Provide multiple time options for the call
  • Clinical summary: Prepare a 2-3 sentence case overview
  • Key talking points: Emphasize failed alternatives and seizure urgency

Concise Case Summary

Help your provider craft: "[Age]-year-old with [diagnosis] and ongoing seizures despite trials of [list 3-4 medications]. Vigabatrin is indicated for this refractory population, patient is REMS-enrolled with vision monitoring, and delay risks continued seizures and developmental impact."

Supporting Materials

Offer to gather:

  • Recent seizure diary: Showing ongoing seizure frequency
  • Medication timeline: Visual summary of failed treatments
  • Functional impact examples: Specific instances of seizure-related impairment

After-Visit Follow-Up

Documentation to Save

  • Copy of PA submission: Request confirmation from your provider's office
  • REMS enrollment proof: Save certification numbers and forms
  • Baseline vision test: Keep copy of ophthalmology report
  • Medical necessity letter: Request copy for your records

Portal Communication

Use your provider's patient portal to:

  • Check submission status: Follow up if no response in 72 hours
  • Share additional information: Upload new seizure logs or documentation
  • Coordinate with specialists: Ensure all providers have current information
From our advocates: "One family created a shared document with their neurologist's office that tracked every medication trial, side effect, and seizure frequency change. This became the foundation for a successful appeal when the initial PA was denied for 'insufficient documentation of treatment failures.'"

Respectful Persistence

Follow-Up Cadence

Escalation Steps

  1. Provider office manager: If communication breaks down
  2. Department chair: For academic medical centers
  3. Patient advocate: Hospital-based advocacy services
  4. Insurance commissioner: For coverage disputes

Professional Communication

When following up:

  • Be specific: "I'm calling about the vigabatrin PA submitted on [date]"
  • Stay solution-focused: "What additional information would help approval?"
  • Document interactions: Keep notes of all calls and conversations

FAQ

How long does Humana prior authorization take for vigabatrin in North Carolina? Standard decisions are made within 72 hours. Expedited reviews (for urgent situations) are processed within 24 hours.

What if vigabatrin is non-formulary on my Humana plan? Request a formulary exception with prescriber support showing formulary alternatives are ineffective or cause adverse effects.

Can I request an expedited appeal if denied? Yes, if delay would seriously jeopardize your health. Contact Humana member services and explicitly request "expedited Medicare Part D appeal."

Does step therapy apply if I've failed medications outside North Carolina? Medical records from any state showing treatment failures should satisfy step therapy requirements. Ensure your provider documents these thoroughly.

What if my pharmacy can't dispense vigabatrin? Vigabatrin requires REMS-certified pharmacies. CVS Specialty and Accredo are common options, but verify REMS enrollment status.

How much does vigabatrin cost without insurance? Generic vigabatrin costs approximately $4,557 per 100 tablets (500mg), while brand Sabril costs around $19,722 per 100 tablets. Manufacturer assistance programs may be available.

Can my primary care doctor prescribe vigabatrin? While technically possible, many payers require specialist involvement (neurologist/epileptologist) for approval, especially for infantile spasms.

What happens if vision problems develop during treatment? Contact your prescriber immediately. Vision changes may require treatment modification or discontinuation, and should be reported to the REMS program.
