How Horizon Blue Cross Blue Shield of New Jersey denies autoimmune cytopenias (itp + aiha) — and how to counter it

Where Horizon Blue Cross Blue Shield of New Jersey pushes back: 1) Must trial rituximab first; 2) Must trial steroids first; 3) Insufficient hemolysis severity.

Counter-arguments that hold up: Hill et al. International consensus for cold AIHA (BJH 2024) + Berentsen review supports sutimlimab as targeted classical-complement C1s blockade. CARDINAL (Roth NEJM 2021;384:1323-1334) — open-label, 54% composite response in recently-transfused CAD. CADENZA (Roth Blood 2022;140:980-991) — randomized placebo-controlled, composite primary endpoint met by 73% sutimlimab vs 15% placebo. CADENZA Part B (eClinicalMedicine 2024) confirmed durability. For patients with thrombosis / TIA history (CAD doubles thromboembolism risk per Broome Blood 2020) or transfusion dependence, do NOT delay sutimlimab. Steroids inappropriate first-line for CAD per BSH 2017 + Hill 2024 (low response, high toxicity). Rituximab response in CAD ~50% with months-long onset — sutimlimab acts within 1-3 wk.
