Frequently Asked Questions

How long does Aetna prior authorization take for Bylvay in New York? Standard prior authorization decisions are typically made within 1-5 days for complete submissions. Expedited reviews (for urgent clinical situations) must be completed within 24 hours per Aetna policy.

What if Bylvay is not on my Aetna formulary? Most Aetna plans list Bylvay as non-formulary, requiring a medical exception. Your specialist can request coverage based on medical necessity, FDA approval, and lack of therapeutic alternatives.

Can I get an expedited appeal if denied? Yes. New York allows expedited external appeals when delay would seriously jeopardize health or when you're currently taking a non-formulary medication. Decisions must be made within 72 hours (24 hours for urgent non-formulary drugs).

Does step therapy apply to Bylvay? Aetna typically requires documentation of failed or inadequate response to ursodeoxycholic acid and at least one antipruritic medication before approving Bylvay.

What if I'm already taking Bylvay and my plan changes? New York law may require Aetna to continue coverage through the plan year for established patients. Contact Community Health Advocates at 888-614-5400 for assistance.

How much does Bylvay cost without insurance? Annual costs can range from approximately $170,000 to $530,000 depending on the patient's weight and required dosing. The IPSEN CARES copay program can reduce out-of-pocket costs to $0 for eligible patients.

Can my pediatrician prescribe Bylvay? While pediatricians can technically prescribe Bylvay, prior authorization success rates are significantly higher when submitted by pediatric hepatologists or gastroenterologists familiar with the clinical evidence and payer requirements.

What happens if the external appeal is denied? External appeal decisions through New York DFS are final and binding. However, you may still pursue other options such as filing complaints with state regulators or seeking legal counsel for potential bad faith denial claims.

The combination of specialist involvement and comprehensive clinical documentation significantly improves approval odds, especially when families understand their appeal rights under New York law.
