IVIG Financial Assistance: Real Help for a Treatment That Costs More Than Most People’s Mortgage

Here is the number that keeps IVIG patients up at night: $10,000 to $30,000 or more — per infusion. For a treatment that many patients need every 3-4 weeks, indefinitely. That is the reality of immunoglobulin therapy in the United States, and even with insurance, the out-of-pocket burden can be crushing.

But here is what too many patients do not hear soon enough: help exists.

Multiple financial assistance programs — from manufacturer support and copay cards to independent foundation grants and government programs — can dramatically reduce or even eliminate IVIG costs for qualifying patients. The challenge is not that help is unavailable; it is that the programs are scattered, confusing, and rarely explained clearly. This guide maps out every major option, who qualifies, and exactly how to apply.

Why Does IVIG Cost So Much?

Understanding why IVIG is expensive does not make the bill easier to pay — but it helps explain why so many assistance programs exist and why manufacturers, foundations, and the government all play a role.

IVIG is not a pill made in a factory. It is a biologic product derived from human plasma — the liquid portion of donated blood. According to the National Institutes of Health, producing a single dose of IVIG requires plasma from 1,000 or more individual donors. Each donation must be screened, tested for pathogens, processed through a complex fractionation procedure, purified, and then quality-tested before it can be bottled and shipped.

The entire process — from blood donation to finished product — takes 7 to 12 months. The infrastructure, safety testing, and regulatory compliance required at every step are what drive the cost. There is no generic IVIG. While multiple brands exist, each is manufactured through a similarly complex (and expensive) process.

The result: even though demand for IVIG has grown significantly over the past two decades, the supply chain cannot scale the way pharmaceutical manufacturing does for traditional drugs. This scarcity, combined with manufacturing complexity, keeps prices high.

Manufacturer Patient Assistance Programs

Every major IVIG manufacturer operates a patient support program. These programs offer different levels of assistance, from copay reduction for commercially insured patients to free medication for uninsured patients who meet income requirements.

CSL Behring — IgIQ

CSL Behring manufactures Privigen and Hizentra. Their IgIQ program provides:

• Copay assistance for eligible commercially insured patients
• Help navigating insurance and prior authorization
• Connections to independent copay foundations
• Patient assistance for uninsured or underinsured patients (income-based)

To enroll, patients or their providers can call IgIQ directly or visit the CSL Behring patient support website.

Grifols — MyIgSource

Grifols manufactures Gamunex-C and Xembify. The MyIgSource program offers:

• Copay support for eligible patients with commercial insurance
• Insurance navigation assistance
• Connection to independent foundation programs
• Patient assistance for qualifying uninsured patients

Takeda — Patient Support

Takeda manufactures Gammagard, Gammagard S/D, and Hyqvia. Their patient support program provides:

• Copay assistance for eligible commercially insured patients
• Dedicated case managers to help with insurance issues
• Patient assistance programs for uninsured patients based on financial need

Copay Cards and Copay Assistance

Copay cards work like discount cards applied to your out-of-pocket costs. When you fill your IVIG prescription, the copay card covers a portion (or sometimes all) of your copay or coinsurance. Most manufacturer copay programs cover up to a set annual maximum — often $5,000 to $15,000 per year — which can make a dramatic difference.

How to use a copay card:

1. Enroll through the manufacturer’s patient support program (usually online or by phone)
2. Receive a copay card number or physical card
3. Provide the card information to your specialty pharmacy
4. The pharmacy applies the card at billing, reducing your out-of-pocket amount

A few things to know:

• Copay cards are for commercially insured patients only — not Medicare, Medicaid, or Tricare
• Some cards have annual limits; once the limit is reached, you are responsible for the remaining costs
• In some states, copay card payments do not count toward your insurance deductible (check with your insurer)
• You can often combine manufacturer copay support with independent foundation grants

Independent Foundation Grants

Several independent nonprofit foundations provide copay assistance grants to patients with specific diagnoses. Unlike manufacturer programs, these foundations can help patients with any type of insurance, including Medicare. Grants are typically awarded on a first-come, first-served basis and may cover copays, coinsurance, deductibles, and sometimes even premiums.

Key Foundations for IVIG Patients

Foundation funds open and close throughout the year depending on available funding. When a fund is “open,” apply immediately — they can close within days or even hours. Many patients set up alerts or check the foundation websites weekly. Your specialty pharmacy may also track fund availability and notify you when a relevant fund opens.

Government Programs: Medicare and Medicaid

Medicare

Medicare Part B covers IVIG for patients with primary immunodeficiency when administered at home — this is one of the few self-administered drugs covered under Part B. For IVIG administered in a doctor’s office or outpatient setting, it is also covered under Part B. Medicare Part D may cover certain immunoglobulin products in specific circumstances.

Even with Medicare, the 20% coinsurance on IVIG can be thousands of dollars per infusion. Options to reduce this include:

• Medigap (Medicare Supplement) policies — many cover the 20% coinsurance
• Medicare Extra Help (Low-Income Subsidy) — reduces Part D costs for qualifying patients
• State Pharmaceutical Assistance Programs (SPAPs) — some states offer additional help
• Independent foundation grants (described above) — available to Medicare patients

Medicaid

Medicaid covers IVIG in all states, though specifics vary by state program. For patients who qualify based on income, Medicaid typically covers IVIG with minimal or no out-of-pocket cost. If you have been denied Medicaid but believe you qualify, contact your state’s Medicaid office or a local legal aid organization for assistance.

Some patients qualify for both Medicare and Medicaid (“dual eligible”). In this case, Medicaid typically covers what Medicare does not, and out-of-pocket costs can be very low or zero.

Hospital Charity Care

If you receive IVIG in a hospital outpatient setting, you may be eligible for the hospital’s financial assistance or charity care program. Under the Affordable Care Act, nonprofit hospitals are required to have financial assistance policies and to make them available to patients. These programs can reduce or write off the patient’s portion of the bill based on income.

To access charity care:

1. Ask the billing department for a financial assistance application
2. Provide documentation of your household income (tax returns, pay stubs)
3. The hospital will evaluate your application against their financial assistance policy
4. If approved, your bill may be reduced or eliminated entirely

This option is especially valuable for uninsured patients or those with high deductibles who receive IVIG in a hospital setting.

Steps You Can Take Today

Financial stress on top of a chronic condition is exhausting. But the path forward is clearer than it seems. Here is what to do, starting right now:

1. Call your IVIG manufacturer’s patient support line. Every manufacturer listed above has a dedicated phone number. Even if you are not sure which brand you use, your specialty pharmacy can tell you. Call and ask what programs you qualify for.
2. Ask your specialty pharmacy for help. Many pharmacies have financial counselors or patient advocates on staff who specialize in connecting patients with assistance programs. If your pharmacy does not offer this, ask them who does.
3. Apply to foundation grants now. Visit the NORD, PAN Foundation, and Chronic Disease Fund websites. Check if funds for your diagnosis are currently open. If they are closed, sign up for notifications.
4. Review your insurance benefits. Understand your deductible, coinsurance, and out-of-pocket maximum. Know whether IVIG is covered under your medical or pharmacy benefit. See IVIG Insurance Coverage for a detailed guide.
5. Ask about prior authorization status. A pending or denied prior auth can delay access to all financial assistance programs. Make sure your coverage is approved or actively being appealed.
6. Talk to a social worker. If you receive care at a hospital or large clinic, ask for a referral to a social worker. They know the local and national resources that can help — and they do this every day.
7. Do not stop treatment because of cost. Skipping infusions can have serious health consequences. If you are at risk of missing treatment due to cost, tell your doctor immediately. Emergency options may be available.

You Are Not Alone in This

The financial burden of IVIG is real, and the frustration of navigating a confusing web of programs while managing a chronic condition is completely valid. But the programs described in this guide have helped thousands of patients access the treatment they need. Many patients who felt overwhelmed at the beginning found that, with the right guidance, the financial picture became manageable.

If there is one thing to remember from this article, let it be this: do not assume you cannot afford treatment until you have explored every option. The manufacturer, the foundation, the social worker, the pharmacy — each one holds a piece of the puzzle. And more often than not, the pieces fit together in a way that makes treatment possible.

For patients still navigating the insurance side of the equation, the companion article on IVIG insurance coverage provides a step-by-step guide to approvals, denials, and appeals. For a broader look at how step therapy affects access to biologics like IVIG, that guide covers your rights and options as well.
