Who Should Use This Guide

This guide is for Michigan residents with Humana Medicare Advantage or Part D coverage who need Spinraza (nusinersen) for spinal muscular atrophy (SMA). You'll find this helpful if you're:

  • Newly diagnosed with SMA and starting treatment
  • Facing a Humana denial for Spinraza coverage
  • Switching from another SMA medication
  • Moving to Michigan with existing Spinraza therapy

Expected outcome: With proper documentation and following this process, most medically appropriate Spinraza requests get approved. Humana's Medicare Advantage denial rate is relatively low at ~3.5%, and appeals are often successful when clinical criteria are met.
