Which Option Below Best Describes Your Insurance Situation?

I Have Insurance Through an Employer or Private Individual Policy

BIMZELX prescriptions will cost the majority of patients between $0 and 26% of drug cost every two months based on their benefit design.3

What you pay for BIMZELX will depend on your insurance plan. Each plan has different preferred drug lists and out-of-pocket amounts, and most include an annual deductible. If you haven’t met your deductible, you’ll see higher prices until the deductible is met; then your out-of-pocket cost will likely drop. Commercially insured patients may pay as little as $5 per dose utilizing UCB’s savings programs. If you have additional questions about affordability, you can reach out to one of our BIMZELX Nurse Navigators at 1-833-931-6877.

I Have Medicare Coverage

If you have Part D coverage and are eligible for the Extra Help4 program, you can expect to pay $4.50-  $11.20 for each prescription.5

If you are unsure whether you qualify for Extra Help, please visit the Social Security Administration website for more information.

If you don’t qualify for Extra Help, your out-of-pocket costs may vary throughout the year depending on which phase of the Part D benefit you are currently in.


I Have Medicaid Coverage
