What This Guide Covers

This guide helps patients with relapsing multiple sclerosis (MS) and their healthcare providers navigate UnitedHealthcare's prior authorization (PA) process for Rebif (interferon beta-1a) in Washington state. Rebif is an FDA-approved disease-modifying therapy that reduces MS relapses by 30-34% in clinical trials, but it requires PA approval and costs over $10,000 per 12-syringe carton without insurance coverage.

Who this helps:

  • Patients newly diagnosed with relapsing MS
  • Those switching from other DMTs due to failure or intolerance
  • Providers submitting initial or renewal authorizations
  • Patients facing denials who need appeal guidance
