If denied, New Jersey residents can appeal through Humana's internal process, then file a free external review with the Independent Health Care Appeals Program (IHCAP) within 60 days.

Policy Overview: Humana's Vigabatrin Coverage

Humana Medicare Advantage and Part D plans in New Jersey require prior authorization for vigabatrin, whether generic or brand name Sabril. This applies to most Humana plans including the Basic Rx Plan (PDP S5884-131-0) and Gold Plus HMO (H6622-066).

The medication typically falls under Tier 4 or 5 coverage, meaning higher copays (21-47% coinsurance), but exact placement varies by specific plan. Check your plan's formulary at Humana.com/MedicareDrugList or call member services.

Note: New Medicare enrollees get a 90-day grace period without prior authorization requirements to avoid care disruption, effective July 1, 2024.

FDA Indication Requirements

Vigabatrin has two FDA-approved indications that Humana covers:

  1. Infantile spasms (monotherapy) - Ages 1 month to 2 years
  2. Refractory complex partial seizures (adjunctive therapy) - Ages 2 years and older

The medication must be used within these specific age ranges and clinical scenarios. Off-label use requires additional justification and may face higher denial rates.

Required ICD-10 Codes

  • G40.4 - Infantile spasms
  • G40.2 - Localization-related (focal) epilepsy with complex partial seizures

Step Therapy & Medical Exceptions

Required Failed Medication Trials

Humana requires documentation of inadequate response or intolerance to at least 2-4 prior antiseizure medications before approving vigabatrin. Common first-line medications include:

  • For infantile spasms: ACTH, corticosteroids, levetiracetam
  • For refractory seizures: Levetiracetam (60 mg/kg/day), topiramate, carbamazepine, phenytoin

Documentation Requirements

For each failed medication, include:

  • Specific drug name and dosage
  • Duration of trial (minimum 2-4 weeks for most AEDs)
  • Reason for failure (lack of efficacy, intolerable side effects, contraindication)
  • Dates of treatment
Tip: Out-of-state medication failures count if thoroughly documented with pharmacy records or provider notes.

REMS Program Requirements

All vigabatrin products require enrollment in the FDA-mandated Vigabatrin REMS program due to risk of permanent vision loss. This is a shared system covering all brands and generics.

  • Post-treatment: Follow-up as clinically indicated

Required Diagnostics & Documentation

Essential Clinical Documentation

  • EEG results showing seizure pattern (hypsarrhythmia for infantile spasms)
  • MRI or CT if structural abnormalities suspected
  • Baseline vision assessment from ophthalmologist

What if vigabatrin isn't on my Humana formulary? You can request a formulary exception through the prior authorization process. Include strong medical necessity justification and evidence that formulary alternatives are inappropriate.

What happens if I develop vision problems on vigabatrin? Report immediately to your prescriber and the REMS program. Vision changes may require treatment discontinuation and affect ongoing coverage approval.
