**Depending on your income or, in some cases, if your medication is obtained from an out-of-network provider, effective January 1, 2021 there is an annual cap that limits the amount of assistance that you can receive over one year. Federal and state laws and other factors may prevent or otherwise restrict eligibility. People covered by Medicare, Medicaid, the VA/DoD, or any other federal plans are not eligible to enroll. You may be eligible to enroll in the Biogen Copay Program for as long as it is offered and you are treated with a Biogen relapsing MS medication.
