Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement.

Provider actions and documentation

Prior Authorization

Prior authorization is required for initial and continuation therapy. Submission of medical records confirming the required diagnostic, treatment history, and response is required. Initial authorizations and reauthorizations will be for no more than 12 months.

Documentation Required

Clinical documentation required (MGFA, MG-ADL baseline/changes, prior therapies, electrodiagnostics, neurologist involvement)

Required clinical documentation includes MGFA clinical classification, MG-ADL score at baseline and documented changes (including ≥2-point improvement for continuation), prior immunosuppressive therapy trials, prior IVIG/PLEX courses, electrodiagnostic evidence for CIDP per EFNS/PNS criteria, and that the prescription was made by or in consultation with a neurologist.

Clinical evidence and supporting information were updated in this revision (see Summary of Changes). Key trial endpoints referenced in the updated Clinical Evidence include: Vyvgart (efgartigimod alfa-fcab) MG-ADL responder rate advantage (67.7% vs 29.7%, p < 0.0001), Vyvgart QMG responder rate (63.1% vs 14.1%, p < 0.0001), Rystiggo (rozanolixizumab-noli) MG-ADL change at day 43 (-3.4 vs -0.8, p < 0.001), and Vyvgart Hytrulo CIDP hazard ratio for time to deterioration (HR 0.394, 95% CI: 0.253–0.614; p < 0.0001).

More detailed supporting information and full references are provided in the archived and updated Supporting Information and Clinical Evidence sections as noted in the changes entry.

Definitions

MG-ADL: The Myasthenia Gravis Activities of Daily Living scale is an 8-item instrument with a total score ranging from 0 to 24; higher scores indicate greater impairment. Clinically meaningful change is commonly considered a 2-point reduction for responder definitions used in trials.

MGFA: The Myasthenia Gravis Foundation of America Clinical Classification (MGFA) is used to describe clinical severity (classes II–IV are referenced in criteria for initiation of therapy).

CIDP EFNS/PNS: Electrodiagnostic criteria per the European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) define demyelinating features (e.g., motor distal latency prolongation, reduced motor conduction velocity, prolonged F-wave latency, absent F-waves, conduction block, abnormal temporal dispersion, distal CMAP duration increase) required to support a diagnosis of definite CIDP.

Background: This policy covers FcRn blockers that reduce circulating IgG, specifically efgartigimod alfa-fcab (Vyvgart IV), efgartigimod alfa + hyaluronidase (Vyvgart Hytrulo SC vial), and rozanolixizumab-noli (Rystiggo SC).

As noted in the Coverage Rationale, the Vyvgart Hytrulo prefilled syringe is a self-administered subcutaneous product obtained under the pharmacy benefit and is not covered under this medical benefit policy.
