FAQ: Common Renewal Questions

How long does BCBSM take to process Xospata renewals? Standard renewals take 15 business days. Expedited reviews for urgent cases are completed within 72 hours when physician documentation supports medical urgency.

What if my FLT3 mutation status has changed? Repeat FLT3 testing is required if disease progression occurs. BCBSM may deny renewal if FLT3 mutations are no longer detectable, as this affects Xospata's mechanism of action and clinical benefit.

Can I request an expedited renewal? Yes, if delaying treatment would jeopardize your health. Your hematologist must provide written documentation of medical urgency, and you must be within 7 days of running out of medication.

What happens if I miss my renewal deadline? Coverage will lapse, but you can still submit a new prior authorization request. Consider patient assistance programs to bridge any gap in coverage during processing.

Does step therapy apply to Xospata renewals? No additional step therapy requirements were added for 2025. However, BCBSM may require documentation that alternative therapies remain inappropriate or have failed.

How do I appeal a renewal denial in Michigan? File an internal appeal with BCBSM within 180 days, then request external review through Michigan DIFS within 127 days of the final internal denial.

Are there cost assistance options during renewal gaps? Yes, the Astellas Patient Assistance Program provides free medication for eligible patients during coverage gaps or appeals.

What documentation is most important for renewal success? Treatment response data showing clinical benefit is crucial. This includes recent bone marrow biopsies, blood count improvements, or stable disease documentation from your hematologist-oncologist.
