Frequently Asked Questions

How long does Blue Cross Blue Shield prior authorization take in New York? Standard PA decisions are issued within 5-7 business days. Expedited requests (when health is at serious risk) are decided within 72 hours.

What if Elzonris is non-formulary on my plan? You can request a formulary exception with clinical justification. If denied, the appeals process applies, including external review through New York DFS.

Can I request an expedited appeal? Yes, if your physician attests that your health is in serious jeopardy. Expedited appeals are decided within 72 hours (24 hours for urgent drug denials).

Does step therapy apply to Elzonris? BPDCN is a rare cancer with limited treatment options. Most BCBS plans don't require step therapy for Elzonris when used for FDA-approved indications, but confirm with your specific plan.

What happens if I start treatment before PA approval? Claims will likely be denied, and you may be responsible for the full cost (~$38,579 per vial). Always wait for PA approval unless it's a life-threatening emergency.

Can my provider file an appeal on my behalf? Yes, providers can file appeals within 60 days of a denial. However, as the patient, you also have independent appeal rights with longer timelines (4 months for external appeals in New York).

What if my BCBS plan is through Medicare or Medicaid? Different rules may apply. Medicare Advantage plans follow Medicare appeals processes, while Medicaid managed care has both DFS external appeals and state Fair Hearing options.
