What Horizon Blue Cross Blue Shield of New Jersey's policy requires for myasthenia gravis & cidp

Cited policy: BCBS Vyvgart Hytrulo (efgartigimod alfa + hyaluronidase) SC for CIDP

Diagnosis of CIDP per EAN/PNS 2021 criteria (definite or probable) confirmed by neuromuscular specialist. ICD-10 G61.81. Documented inadequate response, intolerance, or chronic dependence on standard CIDP therapy (IVIG, corticosteroids, or PLEX). INCAT or I-RODS disability documented. Reauth at 6 mo with disability scoring response.

How Horizon Blue Cross Blue Shield of New Jersey denies myasthenia gravis & cidp — and how to counter it

Where Horizon Blue Cross Blue Shield of New Jersey pushes back: 1) Must fail IVIG, steroids, AND PLEX before Vyvgart; 2) IVIG-responsive patients should continue IVIG indefinitely; 3) CIDP diagnosis questioned without nerve biopsy.

Counter-arguments that hold up: ADHERE (Allen Lancet Neurol 2024) — Phase 3 Vyvgart Hytrulo SC in CIDP enrolled BOTH IVIG-refractory AND IVIG-responsive patients on chronic IVIG dependence; significant relapse-risk reduction. Supported FDA approval Jun 21, 2024 — label is CIDP, no step-therapy requirement. EAN/PNS 2021 (Van den Bergh JPNS 2021) lists IVIG/steroids/PLEX as PARALLEL first-line, NOT sequential. Chronic IVIG dependence is itself an indication. EAN/PNS 2021 diagnostic criteria do NOT require nerve biopsy — definite/probable based on clinical + electrodiagnostic features (NCS demyelinating: prolonged distal motor latency, conduction velocity slowing, partial conduction block, prolonged F-waves) with supportive CSF cytoalbuminologic dissociation.
