Answer Box: Getting Vigabatrin Covered by Humana in Pennsylvania

Vigabatrin (Sabril) is typically non-formulary under Humana Medicare Part D plans, requiring a formulary exception with extensive documentation. In Pennsylvania, your fastest path to approval involves three key steps: 1) Ensure REMS program enrollment for prescriber, pharmacy, and patient with baseline vision testing documented, 2) Submit a comprehensive formulary exception request with medical necessity letter detailing failed alternatives, and 3) If denied, file an external review with Pennsylvania's Insurance Department within 4 months—which has a 50% success rate for overturning denials. Start today by verifying your Humana plan's formulary status and gathering documentation of prior medication failures.

Understanding Your Denial Letter

When Humana denies vigabatrin coverage, the denial letter will specify the exact reason. Common denial codes include:

Non-formulary status: The drug isn't on your plan's covered medication list. This requires a formulary exception request with detailed medical justification.

Missing REMS documentation: Humana requires proof that all parties are enrolled in the vigabatrin REMS program and that baseline vision testing has been completed.

Insufficient medical necessity: The plan needs more evidence that vigabatrin is medically necessary and that other treatments have failed or are inappropriate.

Age or indication restrictions: For infantile spasms, coverage is typically limited to ages 1 month to 2 years. For refractory complex partial seizures, documentation must show the condition is truly refractory to multiple other antiepileptic drugs.

Tip: Look for the specific denial reason code in your letter and match it to Humana's published coverage criteria to understand exactly what additional documentation is needed.

Fixing Common Issues

Denial Reason How to Fix Required Documentation
REMS not enrolled Complete enrollment for all parties REMS confirmation numbers
Missing vision testing Schedule and complete baseline exam Ophthalmology report with visual fields
Insufficient prior trials Document failed medications Detailed medication history with dates, doses, outcomes
Wrong indication Clarify diagnosis and age appropriateness ICD-10 codes, clinical notes, EEG results
Non-formulary status Request formulary exception Medical necessity letter with clinical justification

FAQ

How long does Humana prior authorization take for vigabatrin? Standard prior authorization decisions are made within 14 days. Expedited reviews for urgent cases can be completed within 72 hours if medical urgency is documented.

What if vigabatrin is completely non-formulary on my Humana plan? You can request a formulary exception, which requires demonstrating medical necessity and that no covered alternatives are appropriate. This process typically takes longer than standard prior authorization.

Can I get an expedited appeal for vigabatrin? Yes, if delay in treatment poses a serious threat to your health. For infantile spasms, developmental urgency often qualifies for expedited review.

Does Pennsylvania's external review apply to Medicare plans? No, Medicare Advantage and Part D plans follow federal appeals processes. Pennsylvania's external review applies to commercial and ACA marketplace plans.

What happens if I start paying out-of-pocket while appealing? Keep all receipts. If your appeal is successful, Humana must reimburse you for covered medications purchased during the appeals process.

How much does vigabatrin cost without insurance? Generic vigabatrin costs approximately $4,557 for a 100-tablet supply (500mg), while brand Sabril can cost around $19,722 for the same quantity.

Do I need a neurologist to prescribe vigabatrin? While not always required, specialist involvement strengthens prior authorization requests. Pediatric neurologists are typically involved for infantile spasms cases.

What if my pharmacy isn't REMS-enrolled? The prescription cannot be filled at a non-enrolled pharmacy. You'll need to transfer to a REMS-certified pharmacy or have your current pharmacy complete enrollment.
