Frequently Asked Questions
How long does Humana prior authorization take in Virginia? Standard PA decisions are made within 30 days of complete submission. Expedited reviews for urgent medical necessity are completed within 72 hours.
What if Xembify is non-formulary on my plan? Non-formulary medications can still be covered through formulary exceptions based on medical necessity. Submit a detailed clinical rationale explaining why preferred alternatives are inappropriate.
Can I request an expedited appeal? Yes, if your doctor certifies that waiting for standard review could seriously jeopardize your health. Virginia allows expedited external reviews decided within 72 hours.
Does step therapy apply if I've been on IVIG outside Virginia? Prior therapy documentation from any state counts toward step therapy requirements. Provide complete records of previous treatments and outcomes.
What if I can't afford Xembify while appealing? Contact Grifols patient assistance programs and explore temporary IVIG options through your immunologist while appeals are pending.
How do I know if my Humana plan covers Xembify? Check your plan's formulary or call member services. All Humana plans in Virginia require prior authorization, but coverage varies by specific plan type.
Can my doctor do a peer-to-peer review? Yes, request a peer-to-peer consultation where your prescriber speaks directly with Humana's medical director to discuss your case.
What happens if external review denies my appeal? The decision is final and binding, but you retain rights to pursue legal action separately if you believe there were procedural violations.
From our advocates: We've seen many Virginia patients succeed with Xembify appeals by focusing on functional immunity testing rather than just immunoglobulin levels. One patient with borderline IgG values but poor vaccine responses and recurrent pneumonia got approved after their immunologist provided detailed vaccination titer results showing functional deficiency despite "normal" lab ranges.
