FAQ

How long does BCBS Texas PA take for Rezlidhia? Standard prior authorization decisions are made within 15 business days. Expedited requests for urgent medical situations are decided within 72 hours.

What if Rezlidhia is non-formulary on my plan? Request a formulary exception by demonstrating medical necessity and failure/contraindication to formulary alternatives. Your oncologist must provide clinical justification.

Can I request an expedited appeal in Texas? Yes, if delay would seriously jeopardize your health. Both internal appeals (72 hours) and external IRO reviews (5 days) have expedited timelines.

Does step therapy apply if I failed treatments outside Texas? Treatment history from any state counts toward step therapy requirements. Provide complete documentation of all prior therapies regardless of location.

What happens if the IRO overturns BCBS TX's denial? The IRO decision is binding. BCBS TX must approve coverage and cannot re-deny for the same medical reasons.

How much does Rezlidhia cost without insurance? List price is approximately $32,000 per month. Patient assistance programs and foundation grants can help reduce out-of-pocket costs while pursuing coverage.

Can I appeal if I have an ERISA plan? ERISA self-funded plans follow federal appeals rules, not Texas IRO process. Check your plan documents or contact HR to determine your plan type.

What if my oncologist won't write a medical necessity letter? Seek a second opinion from another hematologist/oncologist familiar with IDH1-mutated AML. Medical necessity letters are standard practice for specialty drug approvals.
