Berinert Financial Assistance: Copay Cards, Patient Programs, and Free Drug Options

Berinert (C1 esterase inhibitor (human)) is used to treat acute attacks of hereditary angioedema (HAE) in adults and adolescents. The cost can be significant, and that is a real barrier for many people, regardless of whether they have insurance. The good news is that legitimate programs exist to help you afford this medication, and most people who apply find at least one option that fits their situation.


Manufacturer Copay Assistance

If you have commercial (private) insurance, CSL Behring's Berinert Copay Support may be available to you. Copay assistance programs cover a portion or all of your out-of-pocket costs, including your deductible, copay, or coinsurance, depending on the program terms.

To apply, visit https://www.cslbehring.com/patient-support or call the support line listed on that page. You will typically need your insurance card, prescription information, and your prescribing doctor's contact details.

Important eligibility note: Manufacturer copay cards are only available to patients with commercial (private or employer-sponsored) insurance. They cannot be used if your coverage comes from a federal or state program including Medicare, Medicaid, TRICARE, or any other government-funded plan. Using a copay card with a government plan violates federal anti-kickback law.

CSL Behring may offer copay support for eligible commercially insured Berinert patients.


Patient Assistance Programs (Free Drug)

If you are uninsured, underinsured, or on Medicare or Medicaid, a Patient Assistance Program (PAP) may provide Berinert at no cost or very low cost.

CSL Behring operates the CSL Behring Patient Assistance Program, which provides Berinert free of charge to patients who meet income and insurance eligibility requirements. Most programs require an annual income below a set threshold (often 400% to 600% of the federal poverty level, though this varies), and your prescribing doctor will typically need to submit the application on your behalf.

Independent Foundations

Independent nonprofit foundations provide financial assistance based on condition and income, separate from the manufacturer. These are a good option when you earn too much to qualify for a PAP but still cannot comfortably afford your out-of-pocket costs, or when the copay card does not work with your insurance.

The PAN Foundation (Patient Advocate Network Foundation) provides disease-specific grants to help underinsured patients cover out-of-pocket costs including copays, premiums, and transportation. Funds are limited and open on a rolling basis, so it is worth checking regularly if a disease fund applies to your condition.

The HealthWell Foundation offers financial assistance grants for a wide range of conditions, including many of the diseases treated with this medication. Eligibility is based on income and insurance status.

NeedyMeds maintains a free database of patient assistance programs, copay cards, and disease-specific foundations. You can search by drug name or condition to find options you may not have heard of.

The National Organization for Rare Disorders (NORD) provides patient assistance programs for some of the rarer conditions treated with this drug. If you have a rare diagnosis, NORD's assistance fund may be available.


What if Your Insurance Denied Berinert?

Berinert for acute HAE attacks may be denied when diagnosis confirmation or medical records documenting attack severity are missing. A denial is not always the final word. You have the right to appeal, and many denials are overturned with the right documentation.
