Summary
Aetna has established a new medical policy (CPB 1035) for Rozanolixizumab-noli (Rystiggo), a neonatal Fc receptor blocker for generalized myasthenia gravis. The policy requires precertification before treatment, restricts prescribing to neurologists, and establishes specific clinical criteria including antibody positivity, MGFA classification II-IV, MG-ADL score ≥5, and documented failure of at least two immunosuppressive therapies or one immunosuppressive plus IVIG over 12 months. Billing teams must implement prior authorization workflows and track the new HCPCS code J9333.
Action Required
By 2026-08-11, implement the following: (1) Billing team must configure system to require precertification for all Rystiggo claims using J9333 prior to claim submission; (2) Update authorization protocols to require neurologist prescription verification and documented AChR/MuSK antibody positivity, MGFA classification II-IV, and MG-ADL score ≥5 per policy criteria; (3) Configure system to deny claims if member has not failed at least two immunosuppressive therapies over 12 months OR one immunosuppressive plus IVIG, unless documented clinical contraindication exists; (4) Establish precertification submission process to contact (866) 752-7021 or fax (888) 267-3277 with completed Statement of Medical Necessity form; (5) Update billing system to block claims combining J9333 with competing neonatal Fc receptor blockers (Imaavy, Vyvgart, Vyvgart Hytrulo), complement inhibitors (Soliris, Ultomiris, Zilbrysq), or Uplizna; (6) Train front desk and clinical staff that this medication requires neurologist consultation; (7) Configure reauthorization protocols to verify no unacceptable toxicity, disease progression, and documented positive response (MG-ADL, MMT, or MG Composite improvement) for continuation requests. Claims submitted without valid precertification will be denied.
