How to Get Xospata (Gilteritinib) Covered by Blue Cross Blue Shield in Illinois: Complete PA Guide & Appeal Process

Answer Box: Getting Xospata Covered by BCBS Illinois

Blue Cross Blue Shield of Illinois requires prior authorization for Xospata (gilteritinib), typically placing it in non-preferred specialty tiers with quantity limits. Success requires documented FLT3-mutated relapsed/refractory AML, prior therapy failures, and prescriber attestation. Your first step: Have your hematologist/oncologist submit the PA request through BCBS Illinois or their designated vendor (often Carelon for oncology) with mutation testing results and treatment history. If denied, Illinois law provides strong appeal rights including external review within 30 days of final denial. Start the PA process immediately—standard review takes 72 hours, expedited takes 24-72 hours for urgent cases.
